“…Studies have shown that SLAC1 activity loss due to mutation continues to affect CO 2 responsiveness in stomatal closure and does not affect the same way under ABA, suggesting the presence of an ABA independent signalling network under eCO 2 conditions to cause stomatal closure. This adds to the intrigue in the signalling response, and possible answers can be found when we can characterize the full complement of guard cell signalling sensors [ 26 , 27 , 28 , 29 , 30 ]. The role of guard cell chloroplasts in regulating CO 2 has also been extensively studied; they are not directly involved in the control of stomatal closure as induced by CO 2 , as it is controlled by the conversion of CO 2 to protons by carbonic anhydrases with HCO 3 being the primary signalling molecules bringing about changes in the proton concentration, and as a result, controlling the opening and closure of the stomata [ 31 , 32 , 33 , 34 ].…”

The changing dynamics in the climate are the primary and important determinants of agriculture productivity. The effects of this changing climate on overall productivity in agriculture can be understood when we study the effects of individual components contributing to the changing climate on plants and crops. Elevated CO2 (eCO2) and drought due to high variability in rainfall is one of the important manifestations of the changing climate. There is a considerable amount of literature that addresses climate effects on plant systems from molecules to ecosystems. Of particular interest is the effect of increased CO2 on plants in relation to drought and water stress. As it is known that one of the consistent effects of increased CO2 in the atmosphere is increased photosynthesis, especially in C3 plants, it will be interesting to know the effect of drought in relation to elevated CO2. The potential of elevated CO2 ameliorating the effects of water deficit stress is evident from literature, which suggests that these two agents are brothers in arms protecting the plant from stress rather than partners in crime, specifically for water deficit when in isolation. The possible mechanisms by which this occurs will be discussed in this minireview. Interpreting the effects of short-term and long-term exposure of plants to elevated CO2 in the context of ameliorating the negative impacts of drought will show us the possible ways by which there can be effective adaption to crops in the changing climate scenario.

“…Cuticle permeability is a critical parameter influencing drought tolerance (Monda et al, 2021) and is affected by the quantity of cuticular wax (Mao et al, 2012). As the stomatal analysis results could not explain the reduced WLR and drought insensitivity in ditl1 plants, we investigated non-stomatal transpiration reduction.…”

Drought stress is a major abiotic stress that limits rice yield. Therefore, the development of new varieties tolerant to drought stress is a high priority in breeding programs. In this study, 150 rice M10 mutant lines, previously developed using gamma‐ray irradiation, were used, and a drought‐insensitive rice mutant (ditl1) was selected by drought stress screening. The ditl1 mutant exhibited significantly decreased water loss, leaf curling, and H2O2 accumulation under drought stress. Chlorophyll leaching assay and toluidine blue staining suggested lower cuticle permeability in ditl1 mutants than in wild‐type (WT) plants. In addition, transmission electron microscopy revealed that ditl1 plants accumulated more cuticular wax on the epidermal surface. Whole‐genome resequencing analysis suggested that the deletion of a single nucleotide on the LOC_Os05g48260 gene, a putative ortholog of WSD1 (wax ester synthase/diacylglycerol O‐acyltransferase in Arabidopsis), maybe be the gene responsible for the drought insensitive phenotype of ditl1. The ditl1 mutant will be a valuable breeding resource for developing drought stress tolerant rice cultivar.
