“…Gavassi et al (2017) exposed 7‐day‐old seedlings of tomato to a low water potential solution and detected higher shoot and root lengths in phyB1 mutants compared to WT, as well as a higher content of proline and glycine‐betaine. Proline and glycine‐betaine are helpful osmoprotectants that actively support the osmotic regulation of cells, which helps plants cope with drought injury (Abro et al, 2019). The aforementioned escape strategy also contributes to give importance to phyB as a drought stress mediator.…”

Photoreceptors are primarily known as key photomorphogenic modulators of various physiological events during plant development. Although there are different groups of photoreceptors, the phytochrome B (phyB) family mediates developmental responses in a wide range of plant species, from seed germination to flowering. In addition, these molecules also regulate abiotic stress acclimation responses, such as salinity, drought, low/high temperature, high light and heavy metals. The signalling pathways mediated by phyB could enhance plant resistance to environmental stresses, as phyB photoreceptors reduce leaf transpiration, increase the antioxidant system, enhance protective pigments and increase the expression of genes related to plant stress acclimation. Thus, the elucidation of positive or negative roles for phyB in these stress tolerance characteristics would provide essential knowledge for genetic engineering, improving plant growth and development in critical environments. In this review, we cover the main findings on how the phyB family works to modulate abiotic stress by discussing biochemical and molecular aspects of the underlying mechanisms operated by these photoreceptors.

“…Each stage of plant growth is eventually impacted by the impacts of drought on crop output. Additionally, there is a reduction in germination potential, coleoptile length, and vigour (Mahpara et al, 2022;Abro et al, 2019). The primary limiting variables for germination are semi-arid locations and low moisture places.…”

Drought is a significant issue because of the worldwide effects of climate change and the negative effects it has on wheat output. For improving production in water-scarce locations, screening drought-tolerant wheat cultivars is crucial. At the Plant Physiology Division of NIA, Tando Jam, the current experiment was conducted during the Rabi year of 2021. At both the P0.01 and P0.05 probability levels, the growth measurements at the seedling stage revealed extremely significant variations for all characteristics among genotypes, treatments, and interactions. The results demonstrated a stronger osmotic impact when using -0.5 MPa PEG. At the seedling stage, the genotype SDW-3 had higher decreases in a number of growth indices, such as shoot length (-11.3), root length (-72.6), and shoot fresh weight (-4.4), with an increase in PEG (-0.5 MPa) level. According to the results of the current study, all six wheat genotypes' seed incubation shoot, root length, and shoot fresh weight drastically decreased under laboratory conditions due to osmotic stress. The genotype SDW-3 showed the greatest decrease under increased osmotic stress brought on by PEG-6000 (-5.0 MPa). As a result, the genotypes AST-1(V1), SDW-1, and SDW-2 may be employed in future breeding programmes and are drought resistant.
