“…Since previous studies have shown that the NRT2 family has a role in responding to drought and waterlogging stresses, this same functionality should also be investigated for cotton. Thorough study of the gray leaf spot and bacterial wilt RNA-seq data confirmed that the expression of the NRT1/PTR subfamily members was down-regulated after pathogen attack ( Xia et al., 2022 ). Reports are also available which imply that NRT2 family proteins play a role in plant response to light, which ultimately increases photosynthesis.…”

Nitrate transporters (NRTs) are crucial for the uptake, use, and storage of nitrogen by plants. In this study, 42 members of the GhNRT2 (Nitrate Transporter 2 family) were found in the four different cotton species. The conserved domains, phylogenetic relationships, physicochemical properties, subcellular localization, conserved motifs, gene structure, cis-acting elements, and promoter region expression patterns of these 42 members were analyzed. The findings confirmed that members of the NRT2 family behaved typically, and subcellular localization tests confirmed that they were hydrophobic proteins that were mostly located on the cytoplasmic membrane. The NRT2 family of genes with A.thaliana and rice underwent phylogenetic analysis, and the results revealed that GhNRT2 could be divided into three groups. The same taxa also shared similar gene structure and motif distribution. The composition of cis-acting elements suggests that most of the expression of GhNRT2 may be related to plant hormones, abiotic stress, and photoreactions. The GhNRT2 gene was highly expressed, mainly in roots. Drought, salt, and extreme temperature stress showed that GhNRT2 gene expression was significantly up-regulated or down-regulated, indicating that it may be involved in the stress response of cotton. In general, the genes of the NRT2 family of cotton were comprehensively analyzed, and their potential nitrogen uptake and utilization functions in cotton were preliminarily predicted. Additionally, we provide an experimental basis for the adverse stress conditions in which they may function.

“…In order to analyze expression patterns of known and previously unannotated SSPs during immune response, we re-analyzed four published transcriptomes of phylogenetically distant species: the moss Physcomitrium patens (Physcomitrella), Zea mays , Brassica napus , and Solanum tuberosum (Kwenda et al, 2016; Reboledo et al, 2021; D. Wang et al, 2022; Xia et al, 2023; Figure 1A). These transcriptomes were selected based on the following criteria: 1) the plants were infected with either necrotrophic or hemibiotrophic pathogens; 2) the quality of raw data (see Methods); and 3) RNA-seq analysis was performed at different time points after pathogen inoculation.…”

Peptides play a crucial role in regulating plant responses to stress conditions. Small secreted peptides (SSPs) are known to be involved in immune response and are found in all land plants. However, the evolution of stress peptide signaling remains poorly understood. Here, we compared the pathogen-induced transcriptomes of the moss Physcomitrium patens, Zea mays, Brassica napus, and Solanum tuberosum to gain insight into the role of established SSP families from vascular and non-vascular plants in immune response. We identified 50, 76, 135, and 309 known SSP genes, differentially expressed during infection, in P. patens, S. tuberosum, Z. mays, and B. napus, respectively. In addition, a novel family of bryophyte-specific PSY-like peptides that are differentially regulated under infection was identified. The similarity of SSPs across the examined plant species was validated through a comparative analysis of peptide motifs and predicted three-dimensional structures. However, despite the similar patterns of antimicrobial peptide expression, only the RALF peptide family was differentially regulated under infection in both vascular and non-vascular plants. We also found that EPFL peptides, which are involved in growth and development processes in angiosperms, were differentially regulated in P. patens in response to pathogen infection. Thus, our study showed the complex nature of SSP signaling and shed light on the regulation of SSPs in different plant lineages during infection.
