Microbiol. Dissecting these complex phenotypic traits into simpler heritable traits has led to the identification of genes associated with some QTLs for DR. In upland cotton, interminate genotypes yielded more than determinate genotypes in a semiarid environment. Morphological characters which are associated with drought resistance included earliness, shape, size and structure of stomato, size, number and orientation of leaves; presence of cuticle; Waxiness on leaf lamina and stem, rooting pattern, growth habit . The OsRINGzf1 OE plants, with higher leaf-related water content (LRWC) and lower leaf water loss rate (LWLR), exhibited enhanced drought resistance, whereas the RNAi and knockout plants of OsRINGzf1 were more sensitive to drought. 1). Sorghum is well adapted to hot dry environments and regarded as a model for studying drought resistance among the grasses. three key processes contribute to improved drought resistance: (i) acquiring greater amount of water by the root system from the soil profile to facilitate transpiration, (ii) acquiring more carbon (biomass) in exchange for the water transpired by crop, e.g. Euphytica 135:255263, Vijayalakshmi K, Fritz AK, Paulsen GM, Bai G, Pandravada S, Gill BS (2010) Modeling and mapping QTL for senescence-related traits in winter wheat under high temperature. Handbook of plant ecophysiology techniques Kluwer Academic Publishers Dordrecht, The Netherlands, Hare, P.D., Cress, W.A. Other plants, specifically crops like corn, wheat, and rice, have become increasingly tolerant to drought with new varieties created via genetic engineering.

This suggests that ABA may be associated with drought tolerance because of its functions as a signal molecule for regulating stomatal closure and antioxidant defense. It can also serve as drought avoidance mechanisms.

In summary, the results of this study indicate that drought stress caused decline in turfgrass quality and LWC. ins.dataset.adChannel = cid; Results showed that five Mesoamerican lines SEA 5, SEA 15, SER 22, SER 16, SER 8 and one Andean line SEQ 1003 have superior resistance to drought. The ability of root systems to provide for evapotranspirational demand from deep soil moisture and capadty for osmotic adjustment are considered major drought resistance traits in rice and close collaboration between molecular geneticists, plant physiologists, and breeders is needed. Van Gogh had greater LWC than AST7002 as measured at Days 8, 12, and 16. Many of these traits relate to making appropriate use of water when it is available, often with the aim of ensuring reproductive success and grain yield.

In the R Sp population in 2001 the lines responded differently to drought; responses (i.e., differences between irrigated- and drought-grown pairs) ranged from 1.33 to 3.26 t ha 1 ( p 0.001). doi:10.2135/cropsci2008.09.0529, Hall AE (2004) Comparative ecophysiology of cowpea, common bean and peanut. The four treatments were compared based on the data at each sampling date at the 5% probability level. It contains information from experimentally verified protein-coding sequences (CDS), expression profiling under several abiotic stresses (drought, salinity, dehydration and ABA), and computationally predicted protein subcellular localization and cis -regulatory elements (CREs) analysis. Expand 392 Save Alert 'Drought resistance' (DR) is a broader term applied to plant species with adaptive features that enable them to escape, avoid, or tolerate drought stress 4. Stress avoidance due to morphological, anatomical characteristics which themselves are the consequences of the physiological processes induced by drought these zerophytic characteristics are quantitative a d vary according to environmental conditions. Mycorrhizal fungi are known to provide their hosts with increased drought resistance in many circumstances, either through improved resource acquisition, direct uptake of water, or translocation of water obtained by their hosts.
