In a similar microarray study of the drought-resistant species A. duranensis, most contigs belonged to the molecular function category (49%), with fewer belonging to cellular component (26%) and biological process (39%) categories [ 4].
The results of this study demonstrate that the drought stress response in sunflower leaves and roots comprises a complex mechanism involving multiple metabolic pathways.
For 24 of the disease candidate loci in this study and three of the drought tolerance candidates from previous work, we were able to amplify in single copy one or two gametes from the related pine species Pinus sylvestris (Scots pine).
This review describes the recent advances in the study of the effect of drought stress on morpho-biochemical changes in soybean and the application of plant growth-promoting rhizobacteria, marker assisted selection, and different omics approaches to unravel the mechanism of drought tolerance.
Mass-mortality (up to 65% mortality in the locality studied) of the most drought resistant tree in the region, Juniperus monosperma (Engelm)Sarq., resulted in a conspicuously heterogeneous dieback pattern.
This study assessed the drought response of 64 small red-seeded genotypes of common bean grown in a lattice design replicated twice under contrasting moisture regimes, terminal drought stress and non-stress, in Ethiopia during the dry season from November 2014 to March 2015.
Recent progress has been made in the study of drought responses at the molecular, cellular, organ, individual, species, community, and landscape levels.
Not only did Stahle's study bracket the timing of the drought to 897 922 ce, but it also revealed that this drought event was more widespread than previously surmised, affecting regions as far north as central Mexico.
For the remaining six days of the study, the soil drought in the stressed pots decreased ≈ 15 g per day.
Similar results were reported in a recent transcriptome profiling study of the leaf elongation zone under drought that compared the gene expression between drought-tolerant and drought-sensitive rice varieties (Cal et al. 2013).
The first two studies included a study of long-term drought, the first of its kind in the eastern US.
