Here, a sucrose non‐fermenting‐1‐related protein kinase alpha subunit (TaSnRK1α‐1A) is identified as associated with cold stress through integration of genome‐wide association study, bulked segregant RNA sequencing, and virus‐induced gene silencing. It is confirmed that TaSnRK1α positively regulates cold tolerance by transgenes and ethyl methanesulfonate (EMS) mutants. A plastid‐lipid‐associated protein 6, chloroplastic‐like (TaPAP6L‐2B) strongly interacting with TaSnRK1α‐1A is screened. Molecular chaperone DJ‐1 family protein (TaDJ‐1‐7B) possibly bridged the interaction of TaSnRK1α‐1A and TaPAP6L‐2B. It is further revealed that TaSnRK1α‐1A phosphorylated TaPAP6L‐2B. Subsequently, a superior haplotype TaPAP6L‐2B30S/38S is identified and confirmed that both R30S and G38S are important phosphorylation sites that influence TaPAP6L‐2B in cold tolerance. Overexpression (OE) and EMS‐mutant lines verified TaPAP6L positively modulating cold tolerance. Furthermore, transcriptome sequencing revealed that TaPAP6L‐2B‐OE lines significantly increased jasmonic acid (JA) content, possibly by improving precursor α‐linolenic acid contributing to JA synthesis and by repressing JAR1 degrading JA. Exogenous JA significantly improved the cold tolerance of wheat plants. In summary, TaSnRK1α profoundly regulated cold stress, possibly through phosphorylating TaPAP6L to increase endogenous JA content of wheat plants.

“…It has been shown that a protein homologous to HEME Activator Protein 3 (HAP3) subunits of the CAAT Box binding Factors, termed Leafy Cotyledon 1 (LEC1), and three B3-domain transcription factors, including ABA Insensitive 3 (ABI3), FUSCA 3 (FUS3), and LEC2, termed LAFL proteins, are the major factors activating the seed maturation program in a complex network [121][122][123]. The fus3-3 mutant exhibits ovule and seed abortion [124]. The repression of LAFL genes during early embryogenesis has been reported [125].…”

Polycomb repressive complex 1 (PRC1) and PRC2 are the major complexes composed of polycomb-group (PcG) proteins in plants. PRC2 catalyzes trimethylation of lysine 27 on histone 3 to silence target genes. Like Heterochromatin Protein 1/Terminal Flower 2 (LHP1/TFL2) recognizes and binds to H3K27me3 generated by PRC2 activities and enrolls PRC1 complex to further silence the chromatin through depositing monoubiquitylation of lysine 119 on H2A. Mutations in PcG genes display diverse developmental defects during shoot apical meristem (SAM) maintenance and differentiation, seed development and germination, floral transition, and so on so forth. PcG proteins play essential roles in regulating plant development through repressing gene expression. In this review, we are focusing on recent discovery about the regulatory roles of PcG proteins in SAM maintenance, root development, embryo development to seedling phase transition, and vegetative to reproductive phase transition.
