(PDF) Adaptation assessment of drought tolerance in maize populations It is an important food security crop in arid and semi-arid lands, where its production potential is hampered by drought. Sorry, preview is currently unavailable. These results confirm earlier reports that wild relatives and landraces are a good source of drought tolerance alleles.

Drought tolerance indices, formulas, and references. The objective of this study was to assess the extent of variation available in the chickpea minicore germplasm collection for drought tolerance, assessed with the DTI, and identify contrasting sources of tolerance to diversify the genetic base of breeding programs. 2016 Feb;243(2):441-9. doi: 10.1007/s00425-015-2414-1. The parents, F1 progenies and their reciprocals showed significant difference for days to flowering suggesting their diversity with regard to this triat. Phytochemistry 32:11031108, Mittler R, Blumwald E (2010) Genetic engineering for modern agriculture: challenges and perspectives. Much of the molecular work to understand the regulation of drought tolerance has been done in Arabidopsis, helping elucidate the basic processes below. [19] This will allow for a wider range of environments in which these plants can grow. Annual. The indices geometric mean productivity (GMP) and mean productivity (MP) were highly correlated with yield under well-watered (YP) and water-stressed condition (YS) and each othe ILRI works with partners worldwide to help poor people keep their farm animals alive and productive, increase and sustain their livestock and farm productivity, and find profitable markets for their animal products.

HHS Vulnerability Disclosure, Help Tsutsui et al 2009 found Arabidopsis DEAR1 (At3g50260) to respond to pathogen infection, chitin, and oligomers of chitin. The development of staygreen genotypes through hybridization is an important food security strategy in the semi-arid tropics. Rhubarb is drought-tolerant because of its fibrous root systems, but it's also cold-hardy, too! The crop is indigenous to Ethiopian as far as its domestication has long time and genetic diversity exhibited variation among cultivated and wild relatives of the crop concentrated in the country.

All traits revealed high heritability (broad sense) ranging from 60.14% for RCC, to 98.4% for DFL. FOIA Unable to load your collection due to an error, Unable to load your delegates due to an error. Sorghum (Sorghum bicolor [L.] Moench) is the fifth most important cereal crop worldwide and second aftermaize (Zeamays L.) in Kenya. Drought tolerance: Drought tolerance refers to the ability of the plant to produce some yield by withstanding low water potential . Although sorghum is generally considered tolerant, drought stress still significantly hampers its productivity and nutritional quality across its major cultivation areas. Data was collected on plant height (PHT), flag leaf area (FLA), panicle weight (PWT), hundred seed weight (HSW), relative chlorophyll content (RCC), number of green leaves at maturity (GLAM) and days to flowering (DFL). This . Epub 2015 Nov 25. This project aims to select at least 10 lines for agricultural use. Some of these interactions include stomatal conductance, carotenoid degradation and anthocyanin accumulation, the intervention of osmoprotectants (such as sucrose, glycine, and proline), ROS-scavenging enzymes. Characterization and identification of sorghum germplasms which provide desirable traits for genetic improvement is a basis in plant breeding. Accessibility Anthropogenic activities in the past and present eras have created global warming and consequently a storm of drought stress, affecting both plants and animals. 2016 May;18(3):406-16. doi: 10.1111/plb.12409.

Novel sources of drought tolerance from landraces and wild sorghum relatives Forty-four sorghum genotypes that included 16 improved, 9 landraces and 17 wild relatives of sorghum alongside known stay-green sources, B35 and E36-1, were evaluated under well-watered and water-stressed conditions in an alpha-lattice design of three replications. Academia.edu uses cookies to personalize content, tailor ads and improve the user experience. 0414149 Grant No. [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. The mean squares of traits for genotypes by environments revealed interactions at p < 0.05 and p < 0.01. Many of the wild Hordeum species including H. bogdanii, H. secalinum, H. depressum, H. patagonicum, H. bulbosum, HMA, H. euclaston, H. pusillum and H. arizonicum were found in drought and salt-affected dryland habitats, and therefore could be a useful source of tolerance to salt and drought stress (Mano and Takeda, Reference Mano and Takeda 1998). Under certain changing circumstances, there is a need to improve the drought tolerance of the plant. Plant Pathol 60:846856, Schonfeld MA, Johnson RC, Carver BF, Mornhinweg DW (1988) Water relations in winter-wheat as drought resistance indicators. 1), leaf temperature, water use efficiency (WUE), lipid peroxidation, lipoxygenase activity, chlorophyll levels and antioxidant capacity during a drought time course experiment.

Drought Stress Impacts on Plants and Different Approaches to Alleviate Genetic diversity was determined using Diversity Arrays Technology (DArT) sequencing and Quality Control (QC) markers were generated using a java script. Planta The plant hormone ethylene is known to play a key role in drought tolerance; in particular, lower ethylene levels result in higher drought tolerance. Novel sources of drought tolerance from landraces and wild - ICRISAT Both projects have found improved grain yield and will be used to help develop future varieties that can be used commercially.[9].

About 2010 Ethiopian sorghum accessions were phenotyped for different traits at multiple locations. The crop is affected by post-flowering drought; therefore, the study was conducted to screen traits contributing to drought tolerance using BC2F4 sorghum genotypes in stressed and unstressed water conditions in a split-plot design. Funding Source.

Snchez-Martn, J., Mur, L.A.J., Rubiales, D. et al. USDA COOPERATIVE AGREEMENT. This regulation also functions in the control of drought tolerance in the vegetative stage as well as the seed maturation and germination. Elucidating the drought tolerance of barley during seed germination would indeed pave the way towards improving the performance of all cereals. Annu Rev Plant Biol.

Sources of tolerance to terminal drought in the chickpea (C Canales FJ, Montilla-Bascn G, Rispail N, Prats E. Plant Signal Behav. Authors Disclaimer, National Library of Medicine Drought Sorghum (Sorghum bicolor [L.] Moench) is the fifth most important cereal crop worldwide and second after maize in Kenya. This page was last edited on 29 October 2022, at 12:19. Being sessile, plants are more vulnerable to drought stress and consequently reduce plant growth and yield. In this study, we find and characterize the sources of tolerance to drought amongst an oat (Avena sativa L.) germplasm collection of 174 landraces and cultivars. [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). Targeting sources of drought tolerance within an Avena spp. collection This study was undertaken with the aim of identifying new sources of resistance to Striga in comparison with the conventional sources as standard checks.

[18] This significant lag in development is due to the fact that more transgenic ornamental plants are being developed for other reasons than drought tolerance. Plant Physiol Biochem 44:211219, Levitt J (1980) Responses of plants to environmental stresses. sharing sensitive information, make sure youre on a federal Sorghum (2 n = 2 x = 20) is considered a major staple food for a large portion of the world's population. The native form of AREB1 cannot target drought stress genes like RD29B in Arabidopsis, so modification is necessary for transcriptional activation. There were significant differences of most traits evaluated at p < 0.01 across environments.
