Abstract
Pearl millet (Pennisetum glauccum (L.) R. Br.) is an annual,
cross pollinating, monocot crop belonging to the family Poaceae and
sub family Penicedae. It is the sixth most important cereal of the
world and has critical value as food security in some of the world’s
hottest and driest cultivated areas of Africa and Asia. However, the
crop faces constraints to the productivity which includes the
prevalence of different biotic and abiotic stresses. Among them, the
major biotic constraint in pearl millet production is downy mildew
disease caused by the pathogen Sclerospora graminicola (Sacc.)
which has a great negative impact on the Indian economy with an
estimated yield loss of up to 40–60%. The present work was carried
out with an aim to find out the candidate genes responsible for
resistance in pearl millet against downy mildew and comparison of
gene expression between control and infected (different time
interval) tissues within susceptible and resistant genotypes through
RT-PCR.
