“…The impact of water deficit, heat stress, and/or their combination on reproductive processes in major crops has been the subject of intense research efforts, and improving the tolerance of reproductive tissues to these stress conditions is a major goal of breeders and the agricultural biotech industry worldwide (e.g., Bheemanahalli et al., 2019; Da Costa et al., 2022; Fang et al., 2010; Gaur et al., 2019; Ishimaru et al., 2022; Jagadish et al., 2015; Jin et al., 2013; Lawas et al., 2018; Lippmann et al., 2019; Mahrookashani et al., 2017; Oury, Caldeira, et al., 2016; Prasad et al., 2008; Rang et al., 2011; Reichardt et al., 2020; Rivero et al., 2022; Su et al., 2013). As the development and maturation of reproductive tissues, the fertilization process, embryogenesis, and seed maturation involve the coordination of multiple developmental, stress response, and/or programmed cell death (PCD) pathways, under controlled conditions, it was hypothesized that any stress, such as heat stress (HS), water deficit (WD), or their combination (WD + HS), could alter the balance between development and stress response pathways and impair the entire reproductive process (Begcy et al., 2019; Bheemanahalli et al., 2019; Chaturvedi et al., 2021; del Olmo et al., 2019; Djanaguiraman et al., 2018; Endo et al., 2009; Fábián et al., 2019; Hedhly et al., 2020; Jin et al., 2013; Lohani et al., 2020; Lu et al., 2022; Ma et al., 2014; Mareri & Cai, 2022; Oury, Tardieu, et al., 2016; Santiago et al., 2021; Santiago & Sharkey, 2019; Sinha et al., 2021; Su et al., 2013; Sze et al., 2021; Zhang et al., 2021).…”

SUMMARYGlobal warming and climate change are driving an alarming increase in the frequency and intensity of extreme climate events, such as droughts, heat waves, and their combination, inflicting heavy losses to agricultural production. Recent studies revealed that the transcriptomic responses of different crops to water deficit (WD) or heat stress (HS) are very different from that to a combination of WD + HS. In addition, it was found that the effects of WD, HS, and WD + HS are significantly more devastating when these stresses occur during the reproductive growth phase of crops, compared to vegetative growth. As the molecular responses of different reproductive and vegetative tissues of plants to WD, HS, or WD + HS could be different from each other and these differences could impact many current and future attempts to enhance the resilience of crops to climate change through breeding and/or engineering, we conducted a transcriptomic analysis of different soybean (Glycine max) tissues to WD, HS, and WD + HS. Here we present a reference transcriptomic dataset that includes the response of soybean leaf, pod, anther, stigma, ovary, and sepal to WD, HS, and WD + HS conditions. Mining this dataset for the expression pattern of different stress response transcripts revealed that each tissue had a unique transcriptomic response to each of the different stress conditions. This finding is important as it suggests that enhancing the overall resilience of crops to climate change could require a coordinated approach that simultaneously alters the expression of different groups of transcripts in different tissues in a stress‐specific manner.

“…In addition, the study by Liu et al ( 2019 ) found that kestose accumulation likely functioned as a storage carbohydrate that provided energy for rhizosheath formation of switchgrass ( Panicum virgatum ) under drought stress. Maltotriose was a common trisaccharide among rice genotypes in response to drought stress (Da Costa et al, 2022 ). Spm-induced accumulation of these sugars could play positive roles in drought tolerance, but an individual function of these sugars deserved to be further investigated in our further study.…”

Plants have developed diverse defense strategies to reduce the detrimental effects of a wide range of environmental stresses. The objectives of this study were to explore the function of spermine (Spm) on mediating growth and physiological changes in water homeostasis, photosynthetic performance, and oxidative damage and to further examine the regulatory mechanism of Spm on global metabolites reprogramming and associated metabolic pathways in horticultural creeping bentgrass (Agrostis stolonifera) under water and heat stresses. The 21-days-old plants were pretreated with or without 100 μM Spm for 3 days and then subjected to water stress (17% polyethylene glycol 6000), high-temperature stress (40/35°C, day/night), or normal condition (control without water stress and heat stress) for 18 days. Results demonstrated that exogenous application of Spm could significantly increase endogenous polyamine (PAs), putrescine (Put), spermidine (Spd), and Spm contents, followed by effective alleviation of growth retardant, water imbalance, photoinhibition, and oxidative damage induced by water and heat stress. Metabolites' profiling showed that a total of 61 metabolites were differentially or commonly regulated by Spm in leaves. Spm upregulated the accumulation of mannose, maltose, galactose, and urea in relation to enhanced osmotic adjustment (OA), antioxidant capacity, and nitrogen metabolism for growth maintenance under water and heat stress. Under water stress, Spm mainly induced the accumulation of sugars (glucose-1-phosphate, sucrose-6-phosphate, fructose, kestose, maltotriose, and xylose), amino acids (glutamic acid, methionine, serine, and threonine), and organic acids (pyruvic acid, aconitic acid, and ketoglutaric acid) involved in the respiratory pathway and myo-inositol associated with energy production, the ROS-scavenging system, and signal transduction. In response to heat stress, the accumulation of alanine, glycine, gallic acid, malic acid, or nicotinic acid was specifically enhanced by Spm contributing to improvements in antioxidant potency and metabolic homeostasis. This study provides novel evidence of Spm-induced,tolerance to water and heat stresses associated with global metabolites reprogramming in favor of growth maintenance and physiological responses in horticultural plants.
