Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    MOLECULAR TAGGING OF YELLOW STRIPE LIKE (OsYSL) PROTEIN FAMILY GENES FOR GRAIN FE AND ZN CONTENT IN RICE (Oryza Sativa L.)
    (Acharya N.G. Ranga Agricultural University, 2017) AJAY KUMAR, DOKUPARTHI; SRIVIDHYA, A
    Association mapping (AM) provides useful insights on the genetic architecture of traits using a large number of natural populations. However, candidate gene/family based association study provides precise mapping and prompt recovery of major loci associated with respective trait from the gene level, that help to achieve precision in plant breeding. Hence, in the current study the knowledge of functionally characterized genes that participate in the uptake, long distance transport and grain loading of micronutrients viz. Fe and Zn were used for identification of markers/genes that associate with respective traits using genic Indel and SSR markers from these known loci. The grain Fe and Zn content of a total of 67 diverse rice genotypes were analysed with acid digestion method using Atomic Absorption Spectroscopy(AAS). The mean Fe content of the association panel was 55.07ppm, with a highest Fe content of 77.37ppm (BC1F3-75; a line derived from cross involving LND384 and INRC10192). The mean Zn content observed was 22.27ppm wherein the genotype (BC1F3 75 (LND384/INRC10192) showed highest Zn content of 47.63ppm. When compared to the released biofortified rice varieties, a total of six genotypes viz. BC1F375 (77.37ppm, 47.63ppm), Swarna (76.33ppm, 31.71ppm), MTU1061 (63.91ppm, 30.47ppm), LN388 (71.57ppm, 27.72ppm), JGL17004 (64.50ppm, 27.07ppm) and HKR47 (69.40ppm, 26.53ppm) that out performed for Fe (>60ppm) and Zn (>25ppm) content, respectively were identified. A very high significant positive correlation value (r2 = 0.882**) was observed between grain Fe and Zn content measured among the genotypes, denotes that selection for grain Fe content simultaneously improves Zn content also. Genotyping of the association panel was done by employing a total of 40 markers (Indels and SSRs) targeting 18 YSL genes and another 7 reported QTL linked markers. The annealing temperatures for the primers were ranged from 55ºC to 64ºC. Of 41 used, ten markers (24.39%) were polymorphic, suggesting the availability of potential variability for few of the selected loci. The genotyping of association panel resulted in the generation of allele size range of 80bp - 450bp for the markers RM17621 and vf0419060908, respectively. Diversity study using YSL gene specific polymorphic markers in association panel revealed a total of 23 alleles, with an average of 3.8 alleles per loci. Highest number of alleles (6) was observed for YSL2 gene and lowest number of alleles was observed for YSL13 (2). The polymorphism information content (PIC) value for these primers ranged from a 0.59 (04g44300) to 0.88 (vf0509222520), followed by 0.88 (vf0226164382) with an average PIC value of 0.72. Diversity study using four polymorphic QTL linked markers, total of 24 alleles were found with a range of 5 alleles (RM243 and RM3412) to 8 (RM17) and with mean allele value of 6. The polymorphism information content (PIC) value for these primers ranged from a 0.69 (RM3412) to 0.87 (RM17) with an average PIC value of 0.80 Marker – trait association study using TASSEL software revealed 6 YSL gene specific and 5 QTL linked associations, on four chromosomes. The associations at five loci namely, YSL2 (LOC_Os02g43370), YSL8 (LOC_Os02g02460), YSL13 (LOC_Os04g44300), qFe1.1 and (qZn12.1, qFe12.1) were commonly associated with both grain Fe and Zn content. Hence, these regions may governing grain loading of both Fe and Zn. The R2 (%) values of most of the markers that associated with grain Fe and Zn are ≥15%. suggesting the major role of these loci/genes/QTLs in controlling the respective trait. Thus, these can be regarded as potential sources in the simultaneous development of grain Fe and Zn. Among these genes, the potency of YSL2, YSL8 and YSL13 were proved through transgenic approaches also. Hence, our study has revealed the importance of usage of the knowledge about functionally characterized genes in unravelling the association of highly significant and major genomic loci, while highlighting their functional importance to use in targeted breeding programmes with high veracity
