“…DGDG accumulation thickens the head group, increases the concentration of hydroxyl groups, and enhances the repulsive force between adjacent films, which is beneficial to the stability of the bilayer membrane structure (Moellering & Benning, 2011; Chen et al ., 2018). Triticum aestivum is very sensitive to drought, especially at the booting and filling stages (Sanad et al ., 2020). The spring wheat genotype has a shallow root system with several branches, and its rich unsaturated membrane lipids help it to adapt to drought stress and conditions of water shortage.…”

Lipids are the primary form of energy storage and a major component of plasma membranes, which form the interface between the cell and the extracellular environment. Several lipidsincluding phosphoinositide, phosphatidic acid, sphingolipids, lysophospholipids, oxylipins, and free fatty acidsalso serve as substrates for the generation of signalling molecules. Abiotic stresses, such as drought and temperature stress, are known to affect plant growth. In addition, abiotic stresses can activate certain lipid-dependent signalling pathways that control the expression of stressresponsive genes and contribute to plant stress adaptation. Many studies have focused either on the enzymatic production and metabolism of lipids, or on the mechanisms of abiotic stress response. However, there is little information regarding the roles of plant lipids in plant responses to abiotic stress. In this review, we describe the metabolism of plant lipids and discuss their involvement in plant responses to abiotic stress. As such, this review provides crucial background for further research on the interactions between plant lipids and abiotic stress.

Although peroxisomes are integral for both primary and secondary metabolism, how developmental changes affect activity of peroxisomes remains poorly understood. Here, we used published RNA‐seq data to analyze the expression patterns of genes encoding 21 peroxisome metabolic pathways at successive developmental stages of Zea mays and Oryza sativa. Photorespiration was the most represented pathway in adult leaf relative to the juvenile stages. Components of reactive oxygen species (ROS)/reactive nitrogen species (RNS) metabolism, NADPH regeneration, and catabolism of polyamines were also enriched at later stages of leaf differentiation. The most commonly upregulated gene in differentiated leaves across all datasets of both species was BETAINE ALANINE DEHYDROGENASE (BADH). BADH functions in catabolism of polyamines where it converts 4‐aminobutyraldehyde (ABAL) to 4‐aminobutyrate (GABA). We tested the outcome of RNA‐seq analysis by qRT‐PCR in developing Triticum monococcum ssp. monococcum (Einkorn) seedlings. Consistent with the outcomes of RNA‐seq analysis, transcription of BADH and CATALASE3 (CAT3) were upregulated in older seedlings. CAT3 is an essential peroxisome biogenesis factor and a key enzyme of ROS homeostasis. Furthermore, exogenous application of GABA resulted in higher peroxisome abundance and transcriptional upregulation of BADH and a gene encoding another peroxisome biogenesis factor responsible for peroxisome fission, PEROXIN11C (PEX11C), in leaves. We propose that GABA contributes to regulation of peroxisome fission machinery during leaf differentiation.

Breeding crop plants with increased yield potential and improved tolerance to stressful environments is critical for global food security. Drought stress (DS) adversely affects agricultural productivity worldwide and is expected to rise in the coming years. Therefore, it is vital to understand the physiological, biochemical, molecular, and ecological mechanisms associated with DS. This review examines recent advances in plant responses to DS to expand our understanding of DS-associated mechanisms. Suboptimal water sources adversely affect crop growth and yields through physical impairments, physiological disturbances, biochemical modifications, and molecular adjustments. To control the devastating effect of DS in crop plants, it is important to understand its consequences, mechanisms, and the agronomic and genetic basis of DS for sustainable production. In addition to plant responses, we highlight several mitigation options such as omics approaches, transgenics breeding, genome editing, and biochemical to mechanical methods (foliar treatments, seed priming, and conventional agronomic practices). Further, we have
