Drought tolerance can be measured by a plant's ability to resist premature senescence, often described as stay-green.

These observations validate our approach which should be seen as representing a cost-effective initial screen that could be subsequently employed to target drought tolerance in segregating populations. Below is the link to the electronic supplementary material. Hence, understanding both the effects of the stress and plant response is indispensable for improving drought tolerance of the crop. The site is secure. briefly, drought severity values were assessed daily according to a 0-5 scale where 0 = vigorous plant, with no leaves showing drought symptoms; 1 = one or two leaves show mild drought. Data were collected for days to 50% flowering (DTF), dry panicle weight (DPW, g), plant height (PH, cm), yield (YLD, t ha1), 100-grain weight (HGW, g), overall disease score (ODS), overall pest score (OPS), area under Striga number progress curve (ASNPC), maximum above-ground Striga (NS Main conclusion Droughts negatively affect sorghums productivity and nutritional quality.

Anthropogenic activities in the past and present eras have created global warming and consequently a storm of drought stress, affecting both plants and animals. USDA COOPERATIVE AGREEMENT. 2001). Nature 401:914917, Tripathy JN, Zhang J, Robin S, Nguyen TT, Nguyen HT (2000) QTLs for cell-membrane stability mapped in rice (Oryza sativa L.) under drought stress. [4] However, research into the molecular pathways involving stress tolerance have revealed that overexpression of such genes can enhance drought tolerance, leading to projects focused on the development of transgenic crop varieties.

Both projects have found improved grain yield and will be used to help develop future varieties that can be used commercially.[9]. Here's how you know Zhang D, Cheng Y, Lu Z, Wang J, Ye X, Zhang X, Luo X, Wang H, Zhang B. Genetic diversity was determined using Diversity Arrays Technology (DArT) sequencing and Quality Control (QC) markers were generated using a java script. The genotype SE438 produced the highest grain yield (2.65 ton ha1) in water-stressed environment and NA316C yielded highest (3.42 ton ha1) under well-watered (7 mm/day) environment. Plant Signal Behav. Drought, which directly affected the yield of crops and trees, is a natural disaster with a profound impact on the economy. Water stress (0 mm/day) was applied at post-flowering to plant maturity in water-stressed treatment. Transgenic Petunias, Poinsettias, New Guinea Impatiens, and Geraniums are being evaluated for frost, drought, and disease resistance. [9] Another similar project in collaboration with CGIAR, Embrapa, RIKEN, and the University of Tokyo have introduced AREB and DREB stress-tolerant genes into soybeans, finding several transgenic soybean lines with drought tolerance. There were higher genetic predictability ratios for days to flowering, panicle weight and grain weight, suggesting that additive gene action played a bigger role than non-additive genes in the control of these traits. For example, DREB proteins including DREB2A cooperate with AREB/ABF proteins in gene expression, specifically in the DREB2A gene under osmotic stress conditions. Under certain changing circumstances, there is a need to improve the drought tolerance of the plant. [18] However, abiotic stress resistance is being explored in ornamental plants by Ornamental Biosciences. By using our site, you agree to our collection of information through the use of cookies. The parents, F1 progenies and their reciprocals showed significant difference for days to flowering suggesting their diversity with regard to this triat.

It is an important food security crop in arid and semi-arid lands, where its production potential is hampered by drought. It is an important food security crop in arid and semi-arid lands, where its production potential is hampered by drought. [9] Some of these include dehydration-responsive element-binding protein (DREB), ABA-responsive element-binding factor (AREB), no apical meristem (NAM), Arabidopsis transcription activation factor (ATAF), and cup-shaped cotyledon (CUC).

Would you like email updates of new search results? government site. [3] Some examples of short-term and long-term physiological responses include: In response to drought conditions, there is an alteration of gene expression, induced by or activated by transcription factors (TFs). We thank CRF (INIA, Madrid) for kindly supplying the seeds of the accessions used. This . There were significant differences of most traits evaluated at p < 0.01 across environments. [9] Overexpression in the aforementioned plants improves stress and drought tolerance. Ethiopian 'zera zera' sorghum landraces and line developed from them being involved in hybrid development at ICRISAT and other countries in modern sorghum breeding program. sharing sensitive information, make sure youre on a federal To improve utilization of germplasm, a core subset of 387 lines were selected following posteriori grouping of genotypes based on cluster groups obtained through GBS analysis followed by stratified random sampling using quantitative traits. [9] Overexpression of these genes enhance the tolerance of drought, high salinity, and low temperature in transgenic lines from Arabidopsis, rice, and tobacco.
