    NANO ENCAPSULATION OF dsRNA OF METAMORPHOSIS RELATED GENE AND ITS INSECTICIDAL POTENTIAL AGAINST DIAMOND BACK MOTH.
    (Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-03-31) PIMPALZARE, PRANALI SUBHASHRAO.; Deshmukh, Mr. A. G.
    The present investigation entitled “Nano encapsulation of dsRNA of metamorphosis related gene and its insecticidal potential against diamond back moth” was carried out at Biotechnology Centre, Department of Agricultural Botany, Post Graduate Institute, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the academic year 2019-2021. RNA interference (RNAi) technology post transcriptional mechanism triggerd by dsRNA to silence specific genes by down regulating their expression. It has become a potential strategy for functional and regulatory studies of insect genes and has potential to control insect pest. Though it has been challenging to produce effective RNAi in lepidopteran Diamond back moth (P. xylostella). Some important factors significantly influencing the silencing potential effects are concentration and length of dsRNA, nucleotide sequence, and determination of the silencing effect and life stage of the target organism. The P.xylostella shows RNAi effects after feeding of nanoencapsulated dsRNA. Considering the potential impact on the normal physiological functions of healthy adults, Juvenile Hormone Esterase gene select as targets for dsRNA mediated gene silencing. Juvenile Hormone Esterase gene sequence obtained from NCBI database. Off targets were predicted to avoid non target effects. Possible RNAi sites were depicted to identify the region having maximum RNAi targets. The aim of studies was to prepared PLGA nanoparticles, because of their possibility to target specific cells with high biodegradability and biocompatibility. It is approved for human use by the Food and Drug Administration. Here, we describes in great details about the formation and characterization of PLGA nanoparticles. Poly (lactic-co-glycolic acid) nanoparticles synthesized using double emulsification method. PVA (poly vinyl alcohol) used as stabilizer during the synthesis of PLGA nanoparticles. This protocol can be readily adapted to use alternative emulsifiers PVA (e.g. Poly vinyl alcohol) or solvent (e.g. methanol). A typical peak at 380nm having 0.56 absorbance on UV- visible spectroscopy indicates synthesis of PLGA nanoparticles. Particle size and zeta potential are determined with Nanoparticle size analyzer and Zeta potential analyzer. The PLGA nanoparticles characterized during present study showed 244.9 nm particle sizes and -4.59 mV zeta potential. FTIR analysis, carried out in wave range 1000- 4000 cm-1, showed different functional groups like 3884 cm-1 and 3410 cm-1 (Alcohol), 1780 cm-1 (Carbonyl group), 1494 cm-1 and 1666 cm-1 (Glycolic acid) 1382 cm-1, and 1187 cm-1 (Esters), 1472 cm-1 and 1096 cm-1(Vinyl) in PLGA NPs synthesis. The process of encapsulation of dsRNA with PLGA NPs done to increase the insecticidal potential of dsRNA-JHE(A) and dsRNA-JHE(B). The encapsulated nanoparticles were also characterized by UV spectrophotometry, particle size was determined with Nanoparticle size analyzer and Zeta potential analyzer. We provide representative images for nanoparticles produced. Effect of dsRNA and encapsulated dsRNA with PLGA NPs was checked out by performing insect bioassay studies on P. xylostella larvae. The dsRNAs and encapsulated dsRNA with PLGANPs were individually spread on to the cabbage leaf discs and twelve larvae were released into 3 replication. We detected that encapsulated dsRNA-JHE(A) and encapsulated dsRNA-JHE(B) which had the highest mortality 60% and 72% as compared to control 0% (only water) and dsRNA 36% JHE(A) and 48% JHE(B). These findings largely broaden the target selection for RNAi-based technology and deliver dsRNA into the insect and potential against insect damage and insect control management.

    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-10-05) Authors : NAKADE, NIKESH UDARAM.; Advisor : Yadgirwar, Dr. P. V.
    Abstract : The present investigation entitled “EVALUATION OF NSE AT DIFFERENT CONCENTRATIONS AND SOAKING PERIODS AGAINST MAJOR PESTS OF TOMATO” was undertaken on tomato crop (Variety local popular hybrid Abhilash) under field condition At Post Ambadi, Tq. Kuhi, Dist. Nagpur during kharif season of 2020-21 with a view to study effect of different soaking periods on field efficacy of NSE against major pests of tomato. Similarly, investigations were also aimed to evaluate field efficacy of different concentrations of NSE and work out economics of different treatments. The experiment was laid out in a randomized block design with seven treatments replicated three times. The treatments comprised of NSE 5% with 12, 24 and 36 hours soaking period, NSE 7% with 12, 24 and 36 hours soaking period and untreated control. The defoliator (Spodoptera litura), whitefly (Bemisia tabaci), aphid (Myzus persicae), leaf miner (Liriomyza trifolii) and fruit borer (Helicoverpa armigera) were observed as major pests causing damage at various growth stages of the crop. Among the different treatments NSE 7% with 12 hours soaking period was found significantly most effective and was at par with NSE 5% with 12 hours soaking period against all major pests viz., Spodoptera litura, whitefly, aphid, leaf miner and fruit borer. The next effective treatments were, NSE 7% with 24 hours soaking period, NSE 5% with 24 hours soaking period, NSE 7% with 36 hours soaking period and NSE 5% with 36 hours soaking period . However, significantly highest infestations was observed in control (water spray). The highest yield was recorded in NSE 7% with 12 hours soaking period (243.38 q/ha) which was at par with NSE 5% with 12 hours soaking period (229.27 q/ha) and NSE 7% with 24 hours soaking period (218.69 q/ha). Those treatments were followed by NSE 5% with 24 hours soaking period (208.14 q/ha), NSE 7% with 36 hours soaking period (204.58 q/ha) and NSE 5% with 36 hours soaking period (197.53 q/ha). The lowest yield was recorded in untreated control (172.83 q/ha). The highest incremental cost benefit ratio was obtained in the treatment of NSE 7% with 12 hours soaking period (1:6.39) followed by NSE 5% with 12 hours soaking period (1:5.60), NSE 7% when soaked for 24 hours (1:3.80), NSE 5% with 24 hours soaking period (1:3.13), NSE 7% with 36 hours soaking period (1:2.32) and NSE 5% with 36 hours soaking period (1:1.89), respectively.

    Title : Differential gene expression profiling during Fusarium wilting in chickpea using cDNA SCoT markers.
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-07-20) Authors : SHARMA, PALAK.; Advisor : Moharil, Dr. M. P.
    Abstract : Chickpea (Cicer arietinum L.) is an annual, autonomous legume cultivated over 30 different countries having genome size of 740 Mbp and has a place within family Leguminoseae. India is the fundamental and prime producer of the chickpea contributing 65% in total world chickpea production and 75% of area coverage in the world. Various abiotic and biotic stresses are responsible for the loss in chickpea productivity. Fusarium wilt, caused by Fusarium oxysporum f. species ciceris is an economically important disease of chickpea. The pathogen can survive in soil for more than six years even in the absence of chickpea and causes 10%-15% yield losses annually. Keeping in view of importance of this crop and potential threat of Fusarium wilt in chickpea growing areas and to address the need for genomic tools in chickpea for Fusarium wilt resistance, the present investigation entitled “Differential Gene Expression Profiling During Fusarium Wilting in Chickpea Using cDNA SCoT Markers” was undertaken to determine differential gene expression analysis using cDNA-SCoT profiling to identify differentially expressed fragments (DEF’s) in resistant and susceptible cultivars. This study focused on which genes are responsible for Fusarium wilt resistance in the chickpea genotypes. This programme was carried out during 2019-21 at Biotechnology Centre, Department of Agricultural Botany, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Pathogenicity test of Fusarium oxysporum f.sp.ciceri by root dip inoculation method was performed which showed 84 percent wilting in susceptible cultivar at 25th days after inoculation whereas, in resistant cultivar few plants with wilting symptoms were observed. Characterization of resistant and susceptible genotypes of chickpea using quantified cDNA of both plant samples was profiled using 13 SCoT primers, all primers showed reproducibility. About 77 amplicons were generated amongst that 63 were polymorphic and 14 were monomorphic. The polymorphic amplicons were re-amplified (nested PCR) and sequenced using Applied Biosystem by Sanger sequencing method. The DEF’s were further analyzed using computational tools viz., BLAST homology, string protein interaction. Similarity search showed that both the differentially expressed fragment showed maximum homology by i.e 84.21% and 91.43% with Cicer arietinum cysteine rich PAK1 inhibitor like mRNA (LOC101498699) which act as a defensin like peptide. The P21 activated kinase 1 (PAK1) inhibitory compound having antifungal activity. Plant cysteine rich peptides were able to inhibit pathogenic growth and helps the legume formation in plants. String protein interaction studies revealed that the target protein interacts with the regulatory proteins like Receptor-like protein 12; Leucine-rich repeat receptor protein kinase EXS-like which are Leucine Rich Receptor Like Kinase contributes to Fusarium resistance in cereals. Cicer arietinum cystine rich receptor-like protein kinase (XP_004500476.1) interact with many other proteins which suggest the suitability of using this gene as a candidate gene in development of transgenic plants resistance against Fusarium wilt. The cDNA-SCoT technique is becoming increasingly important in the study of differentially expressed genes, the discovery of novel genes, and the exploration of molecular pathways. It should be made available to future researchers as an alternative to cDNA-AFLP, cDNA-SRAP, and other comparable technologies for multifunctional plant gene differential expression applications and studies. The information gained from identifying differentially expressed DEFs in tissues of infected and uninfected plants could be used to predict gene(s) involved in Fusarium wilt resistance in chickpea genotypes, for further, more detailed studies.

    Title : ASSESSMENT OF SILICON EFFECT IN RESPONSE TO CHARCOAL ROT IN SOYBEAN (Glycine max L.).
    (Publisher : Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, Maharashtra., 2022-10-04) Authors : KHODE, VAIBHAVI.; Advisor : JADHAV, Dr. P. V.
    Abstract : The present study entitled “Assessment of silicon effect in response to charcoal rot in soybean (Glycine max L.)” was carried out at Department of Agricultural Botany, Dr. PDKV, Akola during the academic year 2020-21 to evaluate the effect of silicon in response to charcoal rot disease in soybean genotypes. Considering the severity of the disease, potassium silicate (K2SiO3) which is known for activating defense mechanism and enhancing the morphological characters in plants. To identify effect of K2SiO3, mass culture of M. phaseolina was prepared for in-vitro screening under sick pot condition for charcoal rot tolerance in soybean genotypes. Silicon gets accumulated in higher concentration in the epidermal cells and has been detected to benefit the plants that are exposed to biotic stresses. The susceptible genotype, TAMS-38 in charcoal rot infected condition showed disease symptoms whereas resistant genotype AMS-MB-5-18 showed normal growth. But in both the treatments 0.7mM and 1.7mM of K2SiO3 (K2SiO3 + C.R. infected), TAMS-38, AMS-MB-5-18 and JS-335 showed tolerance to charcoal disease as well as healthy growth. To identify the amount of accumulation of silicon in the susceptible and resistant genotypes, SEM-EDX analysis was done. The result revealed higher deposition of the silicon in the trichomes of the susceptible genotype. Accumulation of Si in the genotypes and plant response against charcoal rot disease with different morphological observations was recorded. To assess the in-vitro effect of silicon at phenotypic level various morphological characters were recorded such as plant height (cm), number of branches, 50% flowering (D), days to maturity (D), number of pods per plant, grain yield per plant (g) and 100 seed weight (g). The analysis of variance showed significant difference between the genotypes of different concentrations of Si treated pots (0.7mM and 1.7mM of K2SiO3) with charcoal rot, control pot and Si control. The phenotypic screening of soybean genotype against charcoal rot disease revealed that K2SiO3 leads to better adaptability in soybean genotype under charcoal rot disease condition. The effect of Si was also studied at molecular level by using cDNA-RAPD profiling which revealed due to K2SiO3 treatments various genes were activated in response to charcoal rot disease. Each cluster represents different response towards charcoal rot in each individual genotype. Out of the total screened alleles 75 were monomorphic alleles with an average of 3.75 and 69 were polymorphic alleles with an average of 3.45. Results showed an average of 47.68 polymorphism percent. The IDVs (intensity derived values) were calculated to study expression of varying size of polymorphic amplicons. The highest IDV (241002) value was recorded for primer OPH-12 in 1.7 mM of K2SiO3 treated plant of susceptible genotype TAMS-38. The study revealed that both the treatments 0.7mM and 1.7mM of K2SiO3 showed healthier growth in all three soybean genotypes. 1.7mM of K2SiO3 treatment showed superior results at morphological as well as molecular level.
