UV - B radiation exposure for upto 3 h did not cause direct damage to physiology, but adjusted secondary metabolism and metabolites accumulation as an effective acclimation mechanism to mitigate the adverse effects of radiation. Artemisia annua L. plants were irradiated with UV-B radiation (280–315 nm; 2.8 Wm−2) for different short-term (1, 2, 3 and 4 h)(More)
In vitro propagated Artemisia annua plantlets were exposed to low dose (2.8 W m−2) of UV-B (280–315 nm) radiation for different short-term (1, 2, 3 and 4 h) durations that resulted in 103 and 100 % enhanced artemisinin and flavonoid yield respectively after 3 h of UV-B irradiation. UV-B irradiation resulted in reduced chlorophyll a, b and carotenoids while(More)
Root length and its architecture govern the adaptability of plants to various stress conditions, including drought stress. Genetic variations in root growth, length, and architecture are genotypes dependent. In this study, we compared the drought-induced transcriptome of four genotypes of Gossypium herbaceum that differed in their drought tolerance(More)
Transcription factors (TF) play a crucial role in regulating gene expression and are fit to regulate diverse cellular processes by interacting with other proteins. A TF named calmodulin binding transcription activator (CAMTA) was identified in Arabidopsis thaliana (AtCAMTA1-6). To explore the role of CAMTA1 in drought response, the phenotypic differences(More)
Genome-wide gene expression profiling and detailed physiological investigation were used for understanding the molecular mechanism and physiological response of Gossypium herbaceum, which governs the adaptability of plants in drought conditions. Recently, microarray-based gene expression analysis is commonly used to decipher genes and genetic networks(More)
Sweet corn has emerged as one of the popular choices as fresh and processed vegetables, worldwide. Two genes namely, sugary1 (su1) and shrunken2 (sh2) that cause significant increase in sugar levels of endosperm, have been extensively used in sweet corn cultivar development. In order to identify and validate microsatellite/SSR markers linked to su1 and sh2,(More)
Application of traditional Chinese drug, artemisinin, originally derived from Artemisia annua L., in malaria therapy has now been globally accepted. Artemisinin and its derivatives, with their established safety records, form the first line of malaria treatment via artemisinin combination therapies (ACTs). In addition to its antimalarial effects,(More)
Cotton is mostly cultivated under rain-fed conditions in India, thus faces frequent drought conditions during its life cycle. Drought being a major stress factor responsible for yield penalty, there has always been a high priority to generate knowledge on adaptation and tolerance of cotton. In the present study, four cotton varieties, JKC-770 and KC-2(More)
The effects of Zn deficiency on antioxidant responses of two pea (Pisum sativum L.) genotypes, a Zn-efficient IPFD-99-13 and Zn-inefficient KPMR-500, grown in sand culture were studied. In the pea genotype KPMR-500, Zn deficiency decreased dry matter yield, tissue Zn concentration, and antioxidant enzyme activities istronger than in the genotype IPFD-99-13.(More)
A set of 24 genotypes bred at different centres in India as well as in CIMMYT showing variability for drought tolerance were selected for molecular and morpho-physiological characterization. A set of 35 SSR markers, having genome-wide coverage, was chosen for genotyping the inbreds. These markers generated a total of 111 polymorphic alleles with an average(More)
