“…In this study, we determined the characteristics of the soybean circadian clock including the periodicity and adjustment of phase responses to ambient cues (light and temperature), which provides basis for the study of clock entrainment in legumes (Figure 2-4). The study of the adaptive mechanism of stress resistance and organ-specific fitness in plants provides theoretical basis for crop cultivation (Han et al, 2014;Han et al, 2015;Liu et al, 2017). Stress signals in the environment, such as drought, are involved in the expression regulation of the clock gene in soybean (Glycine max) (Marcolino-Gomes et al, 2014).…”

In plants, the spatiotemporal expression of circadian oscillators provides adaptive advantages in diverse species. However, the molecular basis of circadian clock in soybean is not known. In this study, we used soybean hairy roots expression system to monitor endogenous circadian rhythms and the sensitivity of circadian clock to environmental stimuli. We discovered in experiments with constant light and temperature conditions that the promoters of clock genes GmLCLb2 and GmPRR9b1 drive a self‐sustained, robust oscillation of about 24‐h in soybean hairy roots. Moreover, we demonstrate that circadian clock is entrainable by ambient light/dark or temperature cycles. Specifically, we show that light and cold temperature pulses can induce phase shifts of circadian rhythm, and we found that the magnitude and direction of phase responses depends on the specific time of these two zeitgeber stimuli. We obtained a quadruple mutant lacking the soybean gene GmLCLa1, LCLa2, LCLb1, and LCLb2 using CRISPR, and found that loss‐of‐function of these four GmLCL orthologs leads to an extreme short‐period circadian rhythm and late‐flowering phenotype in transgenic soybean. Our study establishes that the morning‐phased GmLCLs genes act constitutively to maintain circadian rhythmicity and demonstrates that their absence delays the transition from vegetative growth to reproductive development.

“…Furthermore, a positive correlation exists between the MAP3K18/MAP3K17 gene and the transcriptional level of the ABA signal transduction gene [20]. ABA also interacts with AtrbohF [22] and MAPKs which regulates the stomatal signaling under stress. Meanwhile AtrbohF also interacts with Ca 2+ signaling and improves oxidative stress tolerance in Arabidopsis [23].…”

Drought stress restricts plant growth and development by altering metabolic activity and biological functions. However, plants have evolved several cellular and molecular mechanisms to overcome drought stress. Drought tolerance is a multiplex trait involving the activation of signaling mechanisms and differentially expressed molecular responses. Broadly, drought tolerance comprises two steps: stress sensing/signaling and activation of various parallel stress responses (including physiological, molecular, and biochemical mechanisms) in plants. At the cellular level, drought induces oxidative stress by overproduction of reactive oxygen species (ROS), ultimately causing the cell membrane to rupture and stimulating various stress signaling pathways (ROS, mitogen-activated-protein-kinase, Ca2+, and hormone-mediated signaling). Drought-induced transcription factors activation and abscisic acid concentration co-ordinate the stress signaling and responses in cotton. The key responses against drought stress, are root development, stomatal closure, photosynthesis, hormone production, and ROS scavenging. The genetic basis, quantitative trait loci and genes of cotton drought tolerance are presented as examples of genetic resources in plants. Sustainable genetic improvements could be achieved through functional genomic approaches and genome modification techniques such as the CRISPR/Cas9 system aid the characterization of genes, sorted out from stress-related candidate single nucleotide polymorphisms, quantitative trait loci, and genes. Exploration of the genetic basis for superior candidate genes linked to stress physiology can be facilitated by integrated functional genomic approaches. We propose a third-generation sequencing approach coupled with genome-wide studies and functional genomic tools, including a comparative sequenced data (transcriptomics, proteomics, and epigenomic) analysis, which offer a platform to identify and characterize novel genes. This will provide information for better understanding the complex stress cellular biology of plants.

“…AtRbohC mainly regulates root hair growth and cellular integrity (Foreman et al, 2003;Macpherson et al, 2008). Both AtrbohD and AtrbohF play key roles in root formation, stomatal closure, and in adaptation to multiple biotic and abiotic stresses (Ma et al, 2012;Marino et al, 2012;Jiao et al, 2013;Li et al, 2015;Liu et al, 2017;Sun et al, 2018;Chen & Yang, 2019;. AtRbohE functions in tapetal programmed cell death and pollen development (Xie et al, 2014), and AtRbohI acts in drought stress response in seeds and roots (He et al, 2017).…”

Plasma membrane NADPH oxidases, also named respiratory burst oxidase homologues (Rbohs), play pivotal roles in many aspects of growth and development, as well as in responses to hormone signalings and various biotic and abiotic stresses. Although Rbohs family members have been identified in several plants, little is known about Rbohs in Gossypium. In this report, we characterized 13, 13, 26 and 19 Rbohs in G. arboretum, G. raimondii, G. hirsutum and G. barbadense, respectively. These Rbohs were conservative in physical properties, structures of genes and motifs. The expansion and evolution of the Rbohs dominantly depended on segmental duplication, and were under the purifying selection. Transcription analyses showed that GhRbohs were expressed in various tissues, and most GhRbohs were highly expressed in flowers. Moreover, different GhRbohs had very diverse expression patterns in response to ABA, high salinity, osmotic stress and heat stress. Some GhRbohs were preferentially and specifically expressed during ovule growth and fiber formation. These results suggest that GhRbohs may serve highly differential roles in mediating ABA signaling, in acclimation to environmental stimuli, and in fiber growth and development. Our findings are valuable for further elucidating the functions and regulation mechanisms of the Rbohs in adaptation to diverse stresses, and in growth and development in Gossypium.
