“…The integration of phytohormone has regulated plant developmental processes; however, their intricate regulatory network is often influenced by diverse internal and external stimuli such as biotic and abiotic stresses [1][2][3][4][5][6]. Several genes, especially transcription factors, tend to coordinate with various hormone signaling to respond to endogenous and external stimuli to adapt to the adverse conditions and maintain plant growth and development [2,[7][8][9][10].…”

Brassinosteroids (BRs) play crucial roles in various biological processes, including plant developmental processes and response to diverse biotic and abiotic stresses. However, no information is currently available about this gene family in wheat (Triticum aestivum L.). In the present investigation, we identified the BZR gene family in wheat to understand the evolution and their role in diverse developmental processes and under different stress conditions. In this study, we performed the genome-wide analysis of the BZR gene family in the bread wheat and identified 20 TaBZR genes through a homology search and further characterized them to understand their structure, function, and distribution across various tissues. Phylogenetic analyses lead to the classification of TaBZR genes into five different groups or subfamilies, providing evidence of evolutionary relationship with Arabidopsis thaliana, Zea mays, Glycine max, and Oryza sativa. A gene exon/intron structure analysis showed a distinct evolutionary path and predicted the possible gene duplication events. Further, the physical and biochemical properties, conserved motifs, chromosomal, subcellular localization, and cis-acting regulatory elements were also examined using various computational approaches. In addition, an analysis of public RNA-seq data also shows that TaBZR genes may be involved in diverse developmental processes and stress tolerance mechanisms. Moreover, qRT-PCR results also showed similar expression with slight variation. Collectively, these results suggest that TaBZR genes might play an important role in plant developmental processes and various stress conditions. Therefore, this work provides valuable information for further elucidate the precise role of BZR family members in wheat.

“…SA accumulation is often associated with inhibition of growth, spontaneous cell death, and immune responses (Bruggeman et al 2015; Peng et al 2021). This prompted us to investigate whether SA biosynthesis might be required for MSL10-associated phenotypes.…”

Plants sense and respond to molecular signals associated with the presence of pathogens and their virulence factors. Mechanical signals generated during pathogenic invasion may also be important, but their contributions have rarely been studied. Here we investigate the potential role of a mechanosensitive ion channel, MscS-Like (MSL)10, in defense against the bacterial pathogen Pseudomonas syringae in Arabidopsis thaliana. We previously showed that overexpression of MSL10-GFP, phospho-mimetic versions of MSL10, and the gain-of-function allele msl10-3G all produce dwarfing, spontaneous cell death, and the hyperaccumulation of reactive oxygen species. These phenotypes are shared by many autoimmune mutants and are frequently suppressed by growth at high temperature in those lines. Here, we found that the same was true for all three MSL10 hypermorphs. In addition, we show that the SGT1/RAR1/HSP90 co-chaperone complex was required for dwarfing and ectopic cell death, PAD4 and SID2 were partially required, and the immune regulators EDS1 and NDR1 were dispensable. All MSL10 hypermorphs exhibited reduced susceptibility to infection by P. syringae strain Pto DC3000, Pto DC3000 expressing the avirulence genes avrRpt2 or avrRpm1, but not Pto DC3000 hrpL, and showed an accelerated induction of PR1 expression compared to wild-type plants. Null msl10-1 mutants were delayed in PR1 induction and displayed modest susceptibility to infection by COR-deficient Pst. Finally, stomatal closure was reduced in msl10-1 loss-of-function mutants in response to Pst COR−. These data show that MSL10 modulates pathogen responses and begin to address the possibility that mechanical signals are exploited by the plant for pathogen perception.

“…It has been widely documented that salicylic acid (SA) plays an essential role in plant resistance to biotrophic and semibiotrophic pathogens such as the model pathogen Pseudomonas syringae pv. tomato DC3000 (Pst DC3000) (Chen et al, 2020a ; Peng et al, 2021 ; Zhang et al, 2020c ). On infection with Pst DC3000, SA accumulation is rapidly induced in plants by the activation of SA biosynthesis and repression of SA metabolism, resulting in translocation of NONEXPRESSOR OF PATHOGENESIS‐RELATED GENES 1 (NPR1) from cytoplasm to nucleus.…”

Due to a sessile lifestyle, plants are constantly confronted with various biotic stresses, including fungal infection, bacterial invasion, and virus attack (Chaouch et al., 2010;Liu et al., 2020a;Qi et al., 2012). During the long-term evolution of the arms race with pathogens, plants have evolved sophisticated defence mechanisms to effectively ward off different kinds of pathogens (Li et al., 2020b;
