Lack of uniformity of plant stand while conducting a field experiment can substantially contribute to errors in the prediction of association between plant phenotype and genotype. Among the several factors that can contribute to experimental errors, inconsistent seed depth and plant spacing often occur due to lack of precision when seeds are sown by hand or seed drills. Hence, we compare three planting methods, novel dibbling, seed drill, and hand sowing, to determine the most efficient method f...

Supraoptimal temperatures and unpredictable fluctuations in global climate adversely affect plant growth and development resulting in a severe threat to wheat production. Although all the growth stages of wheat are sensitive to supraoptimal temperatures, the reproductive phase is the most sensitive one as it affects both grain setting and grain filling (GF). High temperature can alter biochemical, physiological, and morpho-anatomical behavior in wheat, which in turn affects its growth and develo...

Terminal heat stress (THS) causes abrupt modulation in the expression of stress-related proteins in developing seeds. These differential expressions are thought to enhance thermotolerance. Hence, a field experiment was conducted with three spring wheat genotypes, Raj 4014 (heat sensitive), K 7903 (heat escaper) and WH 730 (heat tolerant), for the identification of THS-associated proteins. To expose the plants to different levels of temperatures at the time of grain filling, the crop was sown dur...

Pectin-degrading enzymes (pectinase and pectin lyase) were produced in solid state fermentation by Bacillus subtilis SAV-21 isolated from fruit and vegetable market waste soil of Yamuna Nagar, Haryana, India, and identified by 16S rDNA sequencing. Under optimized conditions, maximum production of pectinase (3315 U/gds) and pectin lyase (10.5 U/gds) was recorded in the presence of a combination of orange peel and coconut fiber (4:1), with a moisture content of 60% at 35 °C and pH 4.0 after 4 days...

A lipolytic isolate Bacillus sp. DVL43 was screened from oil contaminated area of common city garbage site using tributyrin as substrate. The qualitative analysis using tributyrin, rhodamine-agar, and Tween20/ Tween 80 indicated that this isolate produced both lipase as well as esterase. The effect of three different production media (PM1, PM2 and PM3) on quantitative production of lipase and esterase by Bacillus sp. DVL43 revealed maximum intracellular and extracellular lipase activity in PM2 a...

Terminal heat stress has the potential negative impact on wheat production across the world, especially in South Asia. Under the threat of terminal heat stress, wheat genotypes with stay green trait would suffer from high temperature stress during their long grain filling duration (GFD). The genotypes with short GFD would be advantageous. To identify quantitative trait loci (QTL) for heat tolerance, a RIL population of K 7903 (heat tolerant) and RAJ 4014 (heat sensitive) wheat genotypes was inve...

Heat stress alters various physiological phenomenons which adversely affect yield components and ultimately lead to a severe reduction in economic yield in wheat (Triticum aestivum L.). To cope with heat stress, plants have army of heat shock proteins (HSPs) which acts as molecular chaperones stabilizing the polypeptides and membranes. The thermo-tolerance ability of different genotypes of a plant species resides in their genetic diversity of HSP genes. In this study, association of HSPs with ph...
