    ABSTRACT: In the present study, six drought susceptible, six drought tolerant and seven wild sorghum genotypes were compared for their response to varying degrees of PEG-6000 induced water stress. Germination percentages, root length, shoot length, root to shoot ratio and chlorophyll content were decreased however membrane injury index was increased with increasing water stress. Under stress drought tolerant genotypes had more chlorophyll a, chlorophyll b, total chlorophyll content and less membrane injury index. A drought tolerant genotype M-35-1 had maximum root length, shoot length, and less membrane injury index than the rest of the genotypes. Proline content and activity of P5CS increased in all genotypes of sorghum due to water stress. Wild genotypes had higher proline content under water stress however; fold increase of proline was higher in drought tolerant genotypes. Soluble protein also increased in all sorghum genotypes in response to imposed water stress. Activities of antioxidant enzymes viz., SOD, POD, CAT increased under stressed condition in all sorghum genotypes. Activities of all these enzymes were higher in drought tolerant genotypes followed by those wild genotypes. Highest antioxidant enzyme activities under moisture stress condition were found in M-35-1, a drought tolerant genotype which may contribute for its better adaptation under water stress.

    ABSTRACT: The objective of this study was to understand how abiotic factors affected dry matter (DM) yield and nutritional composition of maize whole-plant for silage. We analyzed data from maize hybrids performance trials completed at two sites (ie, Southern Piedmont and Shenandoah Valley regions) during 2011 and 2012. Data from eight maize hybrids (110 to 117 days to maturity) were tested in both sites and years. Dry matter yield and nutritional composition were analyzed through mixed model analysis. Climate data were obtained from weather stations located in Blackstone and Elkton (Virginia, USA). Whole-plant DM yields varied significantly across site.years (P < 0.01), ranging from 4,556 to 15,092 kg ha-1. Dry matter (DM; P < 0.01) and crude protein (CP; P < 0.01) concentrations differed among site.years. These high variations are attributed to the low DM concentration (25.3% DM) and to the high CP concentration (10.9% CP) observed for the Southern Piedmont region in 2012. Neutral detergent fiber (NDF; P < 0.01) and acid detergent fiber (ADF; P < 0.01) were significantly different between site.years. That NDF concentration in 2012 was substantially lower for the Shenandoah Valley region (43.0% NDF) than for the Southern Piedmont region (56.6% NDF) indicates that maize crops were affected differently despite summer drought. We concluded that heat stress had a major adverse effect on kernel development in the Southern Piedmont region, but not in the Shenandoah Valley region, and that heat stress exacerbated the effects of drought reducing substantially DM yields and increasing whole plant fiber concentration.

    ABSTRACT: Drought stress is a major challenge for the production of maize (Zea mays L), leading to reduced growth of aerial parts and, to a large extent, reproductive stages of development. We applied the 454 GS FLX titanium platform to identify drought differentially regulated genes in the maize vegetative and reproductive tissues. A total of 2,199 genes of which 1,284 in reproductive and 915 in vegetative tissues were identified by the platform. QuantitativeRT-PCR of differentially expressed genes was carried out to confirm their expression. The results showed thatthe transcripts were correctly assembled and represented actively expressed genes, which genes were furthersubjected to gene ontology analysis for biological processes, molecular function and cell component functionalterms. Significantly enriched terms indicates that catabolism of proteins and maintenance of cellular homeostasisprocesses were significantly enriched in the vegetative tissues, while on the other hand carbohydrate metabolism was enriched in the reproductive tissues. Photosynthesis, and energy metabolism as well as protein biosynthesiswere highly repressed in both tissues. These add to the concept that drought stress target photosynthesis andcauses a transition of metabolism from protein synthesis by repressing amino acid biosynthesis and translation to degradation by inducing the ubiquitin-proteasome pathway. Identified genes are potential candidates for maizeimprovement through transgenic and mutagenic approaches.
