The highly coordinated, dynamic nature of growth requires plants to perceive and react to various environmental signals in an interactive manner. Elaborate signaling networks mediate this plasticity in growth and the ability to adapt to changing environmental conditions. The fluctuations of stress-responsive hormones help alter the cellular dynamics and(More)
Selection for drought-tolerant cereal varieties has successfully moved to screening for grain yield under stress. Grain yield is the culmination of the process of grain filling, which in turn is closely linked to flag leaf functionalities. For grain filling to occur under drought, either a relatively uncompromised or a favorably reprogrammed functioning of(More)
MSI working papers are distributed for the benefit of MSI corporate and academic members and the general public. Reports are not to be reproduced or published in any form or by any means, electronic or mechanical, without written permission. Report Summary Over the past decade, 22% of Fortune 500 firms—acting on the assumption that structuring divisions(More)
Green Revolution (GR) rice varieties are high yielding but typically drought sensitive. This is partly due to the tight linkage between the loci governing plant height and drought tolerance. This linkage is illustrated here through characterization of qDTY1.1, a QTL for grain yield under drought that co-segregates with the GR gene sd1 for semi-dwarf plant(More)
Sub-QTLs and multiple intra-QTL genes are hypothesized to underpin large-effect QTLs. Known QTLs over gene families, biosynthetic pathways or certain traits represent functional gene-clusters of genes of the same gene ontology (GO). Gene-clusters containing genes of different GO have not been elaborated, except in silico as coexpressed genes within QTLs.(More)
Smallholder rice cultivation productivity is directly related to alleviating hunger and poverty. Biotic and abiotic stresses increasingly subvert the process, and drought is the most common stress. A mechanistic understanding of plant response to drought could lead to the use of gene-based markers to generate drought-tolerant rice. Such an understanding is(More)
Plants respond to stress conditions through early stress-response factors (ESRF), which serve the function of stress sensing and/or signal transduction. These mainly comprise qualitative and/or quantitative flux in the redox molecules, calcium ions (Ca2+), phosphatidic acid, hexose sugars and phytohormones. The role of resident proteins such as phytohormone(More)
Plant proteomics has made tremendous contributions in understanding the complex processes of plant biology. Here, its current status in India and Nepal is discussed. Gel-based proteomics is predominantly utilized on crops and non-crops to analyze majorly abiotic (49 %) and biotic (18 %) stress, development (11 %) and post-translational modifications (7 %).(More)
Quantitative reverse transcription PCR (qRT-PCR) has been routinely used to quantify gene expression level. This technique determines the expression of a target gene by comparison to an internal control gene uniformly expressed among the samples analyzed. The reproducibility and reliability of the results depend heavily on the reference genes used. To(More)
Present and future food security is a critical issue compounded by the consequences of climate change on agriculture. Stress perception and signal transduction in plants causes changes in gene or protein expression which lead to metabolic and physiological responses. Phytohormones play a central role in the integration of different upstream signals into(More)
