“…Drought is recognized as the most significant abiotic stress which affects crops both qualitatively and quantitatively (Lucas et al 2011b; Budak et al 2015b). Altered climate conditions are predicted to lead to increased rates of evaporation and decreased precipitation in many major cropping regions; these conditions are expected to lead to increased severity of drought stress.…”

“…Additionally, it also serves as an important model for Triticeae genetics and genomics studies by courtesy of its diploid genome (Mayer et al 2011; Mayer et al 2012). Given the overall significance of the Triticeae tribe, many biological and physiological studies have been conducted on its members (Kantar et al 2010; Lucas et al 2011a; Lucas et al 2011b; Budak et al 2013a; Baldoni et al 2015a; Budak et al 2015b). However, numerous biological phenomena associated with these crops remain elusive.…”

The continued growth in world population necessitates increases in both the quantity and quality of agricultural production. Triticeae members, particularly wheat and barley, make an important contribution to world food reserves by providing rich sources of carbohydrate and protein. These crops are grown over diverse production environments that are characterized by a range of environmental or abiotic stresses. Abiotic stresses such as drought, heat, salinity, or nutrient deficiencies and toxicities cause large yield losses resulting in economic and environmental damage. The negative effects of abiotic stresses have increased at an alarming rate in recent years and are predicted to further deteriorate due to climate change, land degradation, and declining water supply. New technologies have provided an important tool with great potential for improving crop tolerance to the abiotic stresses: microRNAs (miRNAs). miRNAs are small regulators of gene expression that act on many different molecular and biochemical processes such as development, environmental adaptation, and stress tolerance. miRNAs can act at both the transcriptional and post-transcriptional levels, although post-transcriptional regulation is the most common in plants where miRNAs can inhibit the translation of their mRNA targets via complementary binding and cleavage. To date, expression of several miRNA families such as miR156, miR159, and miR398 has been detected as responsive to environmental conditions to regulate stress-associated molecular mechanisms individually and/or together with their various miRNA partners. Manipulation of these miRNAs and their targets may pave the way to improve crop performance under several abiotic stresses. Here, we summarize the current status of our knowledge on abiotic stress-associated miRNAs in members of the Triticeae tribe, specifically in wheat and barley, and the miRNA-based regulatory mechanisms triggered by stress conditions. Exploration of further miRNA families together with their functions under stress will improve our knowledge and provide opportunities to enhance plant performance to help us meet global food demand.

“…Post-transcriptional regulation of Dehydration Responsive Element Binding Proteins 2 (DREB2) genes by alternative splicing has been reported in Arabidopsis, tomato and wheat (Rehman & Mahmood, 2015;Pirrello et al, 2012;Lata & Prasad, 2011;Lucas et al, 2011;Mizoi et al 2012). In the case of alternative splicing, two types of transcripts may exist.…”

“…TR39477 has previously been shown to tolerate drought better than the other genotypes in this study and the same result was observed here, as measured by loss of leaf greenness. Recently, we showed that an important transcription factor involved in regulation of the drought response, TdicDRF1, is also specifically upregulated in TR39477 but not Ttd22 (Lucas et al, 2011). The similar behaviour of TdicTMPIT1 in root tissue suggests that this protein may have a function in helping to protect the cell against drought-stress related damage.…”
