Plant transformation has been used to develop multiple drought resistant crop varieties, but only limited varieties of ornamental plants. 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). Water stress (0 mm/day) was applied at post-flowering to plant maturity in water-stressed treatment. It is an important food security crop mainly in semi-arid and tropical parts of the African countries. Epub 2018 Sep 10.

[12], DREB proteins are involved in a variety of functions related to drought tolerance. Plants can be subjected to slowly developing water shortages (ie, taking days, weeks, or months), or they may face short-term deficits of water (ie, hours to days). Therefore, the combination of short-term plus long-term responses allow for plants to produce a few viable seeds.

Farmers have traditionally managed Striga using cultural methods, but the most effective and practical solution to poor smallholder farmers is to develop Striga-resistant varieties. Understanding population genetic structure and diversity of a crop is essential in designing selection strategies in plant breeding. The SMIL collection displayed high genetic diversity with some redundancy with the USDA-NPGS germplasm but SAP showed clear distinction. Planta 236, 15291545 (2012). The existence of tremendous amount sorghum variability exhibiting native genetic variation to drought, disease and insect resistance, having good grain quality and high lysine, made Ethiopia as genetic resource reservoir ranking first in contributing germplasm collection worldwide in today's sorghum breeding program.

The collection was assessed for relative water content (RWC), cell membrane stability, stomatal conductance (g (1)), leaf temperature, water use efficiency (WUE), lipid peroxidation, lipoxygenase activity, chlorophyll levels and antioxidant capacity during a drought time course experiment. Plant Physiol Biochem. 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. A collection of maize populations from Saharan oases was evaluated under drought and control conditions in Spain and Algeria. In: Suttie JM, Reynolds SG (eds) Fodder oats: a world overview.

Drought is considered one of the most acute environmental stresses presently affecting agriculture. Different combinations of morpho-physiological traits are responsible for tolerance to drought in wild tomatoes Solanum chilense and Solanum peruvianum. 2007 Jun;10(3):296-302 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.

Fig. Drought tolerance is the ability to which a plant maintains its biomass production during arid or drought conditions. Authors [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). 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. Planta DNA based molecular marker and PCR based are the best to characterize and identify sorghum genotypes which provide desirable traits as compared to field experimental evaluation due to time and environmental effect. Physiological and metabolomic analysis of Punica granatum (L.) under drought stress. Overexpression of DREB2Aca enhances drought and heat stress tolerance levels in Arabidopsis. [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. Keywords: Sorghum spp., Climate change, drought tolerance, stay-green, water stress, CWR, Resaerchjournali's Journal of Agriculutre. Sorghum [Sorghum bicolor (L.)

Citing Literature Supporting Information However, other parameters involved in water use such as g (1) and WUE were less able to discriminate between the accessions. Drought tolerance is an important attribute of commercial maize.20 The plant hormone ethylene is known to play a key role in drought tolerance; in particular, lower ethylene levels result in higher drought tolerance. The site is secure. Download scientific diagram | Drought tolerance indices, formulas, and references. [2], Drought-tolerant plants which are developed through biotechnology enable farmers to protect their harvest and reduces losses in times of intense drought by using water more efficiently. Under certain changing circumstances, there is a need to improve the drought tolerance of the plant. [9], Plants in naturally arid conditions retain large amounts of biomass due to drought tolerance and can be classified into 4 categories of adaptation:[13], Many adaptations for dry conditions are structural, including the following:[14], With the frequency and severity of droughts increasing in recent years, damage to crops has become more serious, lowering the crop yield, growth, and production.
