Phenoty** Drought-Induced Morpho-Physiological Changes and Genetic Diversity Among Pigeon Pea (Cajanus cajan (L.) Millsp.) Genotypes
Drought stress at reproductive stages is mainly responsible for low yield in pigeon pea especially in semi-arid regions. Understanding genetic makeup at the phenotypic and genotypic level for stress tolerance-...

Stress Reactions of Maize Genotypes to Drought Stress at Different Phenophases and Recovery
Maize (Zea mays L.) cultivated worldwide, is often exposed to various biotic and abiotic stresses affecting productivity. We evaluated three maize genotypes, SNJ201126, Z10115 and HKI161 for morpho-physiological,...

Differential response of antioxidative enzymes to various abiotic stresses in Pennisetum glaucum seedlings
Antioxidative enzyme activities and their isozyme patterns under water-deficit, salinity, high and low temperature stresses were studied in the seedlings of Pennisetum glaucum (L.) R.Br. It was observed that unde...

In silico targeted genome mining and comparative modelling reveals a putative protein similar to an Arabidopsis drought tolerance DNA binding transcription factor in Chromosome 6 of Sorghum bicolor genome
Arabidopsis Thaliana HARDY (AtHRD) is a gene with an APETELA 2 / Ethylene Responsive Factor (AP2/ERF) domain linked to improved performance under drought in rice. We hypothesized that the sorghum genome could pos...
