In this study, we found that capsicum annuum 40S ribosomal protein SA-like (CaSLP) was extensively accumulated in the cell nucleus and cell membrane, and the expression level of CaSLP was up-regulated by Salicylic acid (SA) and drought treatment. Significantly fewer peppers plants could withstand drought stress after CaSLP gene knockout. The transient expression of CaSLP leads to drought tolerance in pepper, and Arabidopsis's ability to withstand drought stress was greatly improved by overexpressing the CaSLP gene. Exogenous application of SA during spraying season enhanced drought tolerance. CaSLP-knockdown pepper plants demonstrated a decreased resistance of Pseudomonas syringae PV.tomato (Pst) DC3000 (Pst.DC3000), whereas ectopic expression of CaSLP increased the Pst.DC3000 stress resistance in Arabidopsis. Yeast two-hybrid (Y2H) and bimolecular fluorescence complementation (BiFC) results showed that CaNAC035 physically interacts with CaSLP in the cell nucleus.

Here, we show that an abscisic acid (ABA)-responsive NAC transcription factor (TF) is involved in N deficiency-induced leaf senescence. The overexpression of MdNAC4 led to increased ABA levels in apple calli by directly activating the transcription of the ABA biosynthesis gene MdNCED2. In addition, MdNAC4 overexpression promoted N deficiency-induced leaf senescence. Further investigation showed that MdNAC4 directly bound the promoter of the senescence-associated gene (SAG) MdSAG39 and upregulated its expression. Interestingly, the function of MdNAC4 in promoting N deficiency-induced leaf senescence was enhanced in the presence of ABA. Furthermore, we identified an interaction between the ABA receptor protein MdPYL4 and the MdNAC4 protein. Moreover, MdPYL4 showed a function similar to that of MdNAC4 in ABA-mediated N deficiency-induced leaf senescence. These findings suggest that ABA plays a central role in N deficiency-induced leaf senescence and that MdPYL4 interacts with MdNAC4 to enhance the response of the latter to N deficiency, thus promoting N deficiency-induced leaf senescence.

Comparative transcriptome analysis of loss- and gain- of NtMYB12 tissue relative to wild-type narcissus showed NtMYB12 was mainly involved in flavonol and phenylpropanoid metabolic pathways. Biochemical evidences of dual-luciferase activity and chromatin immunoprecipitation assay supported that MYB12 directly bound to promoters of NtFLS, NtLAR, and NtDFR that were cloned by genome walking assay, and activated NtFLS and NtLAR expression but repressed NtDFR expression. More interestingly, NtMYB12 can interact with NtbHLH1 and NtWD40-1 proteins via R3 domain that were selected by transcriptome-based WGCNA and confirmed by yeast two hybrid, bimolecular fluorescence complementation and coimmunoprecipitation assay. Interaction of NtMYB12 with NtbHLH1 and NtWD40-1 forming MYB-bHLH-WD40 triplex specially activated NtDFR and NtANS expression and promoted (pro)anthocyanin accumulation, while NtMYB12 alone activated NtFLS and NtLAR expression and accumulated flavonols, but repressed NtDFR expression. These results indicated that NtMYB12 alone or NtMYB12-bHLH1-WD40-1 triplex requires for competition of metabolism fluxes between flavonol and (pro)anthocyanin biosynthesis. NtMYB12 dually functions on flavonol and proanthocyanin biogenesis via physically binding to NtFLS and NtLAR promoter activating their expression and on (pro)anthocyanin biosynthesis via NtMYB12-NtWD40-NtbHLH (MBW) triplex activating NtDFR and NtANS expression.

Flower development is a complex process that is very sensitive to ambient temperature, and warming temperatures often lead to abnormal flower development and remarkably reduce the quality and yield of inflorescent vegetables and many other crops, which can be exemplified by Brassica oleracea cv. Green Harmony F1, a broccoli cultivar, whose floral development is ceased at inflorescence meristem (at 28 °C) or floral primordium stage (at 22 °C), forming a cauliflower-like curd (28 °C) or intermediate curd (22 °C) instead of normal broccoli head at 16 °C. However, the underlying molecular regulatory mechanisms are not well understood. Here we report that warming temperature (28 °C or 22 °C) induced hypermethylation of the genome, especially the promoter regions of such sets of genes as ribosome biogenesis-related and others, leading to the suppression of the apex-highly-expressed distinctive genes, subsequently resulting in the abnormal floral development, as revealed by methylome and transcriptome co-profiling. The regulation of warming-induced abnormal floral development in broccoli was further verified by the fact that the DNA methylation inhibitor 5-azacytidine (5-azaC) released the expression of genes from the warming temperature-induced suppression, and restored the broccoli development to normalcy at warming temperature. The research provided new approaches to breeding broccoli and other crops for growing in wider or warmer temperature zones.

Here, we summarize research progress revealing the spatial-temporal expression of FER, along with its co-receptors and ligands determined the function of FER signaling pathway in multiple organs. The specificity of the FER signaling pathway is proposed to operate under a four-layered mechanism: (1) Spatial-temporal expression of FER, co-receptors, and ligands specify diverse functions, (2) Specific ligands or ligand combinations trigger variable FER signaling pathways, (3) Diverse co-receptors confer diverse FER perception and response modes, and (4) Unique downstream components that modify FER signaling and responses. Moreover, the regulation mechanism of the signaling pathway- appears to depend on the interaction among the ligands, RLK receptors, co-receptors, and downstream components, which may be a general mechanism of RLKs to maintain signal specificity.
