The BASIC PENTACYSTEINE (BPC) family represents a group of plant-specific transcription factors with established functions in developmental regulation and environmental adaptation. Although BPC genes have been catalogued in diverse plant species, their genome-wide characterization and light-dependent expression dynamics remain unexplored in the medicinal herb Peucedanum praeruptorum Dunn. Here, we report the systematic identification of eight PpBPC loci from the P. praeruptorum genome assembly through comprehensive bioinformatic screening. Evolutionary reconstruction grouped these eight members into three distinct clades (designated A, B, and C). Comparative genomic analyses revealed pronounced syntenic conservation between PpBPCs and their counterparts in Arabidopsis thaliana, Angelica sinensis, and Daucus carota. Members clustered within the same phylogenetic group displayed analogous exon-intron architectures and conserved motif repertoires, and all possessed the characteristic GAGA-binding domain. Examination of transcript abundance across organs demonstrated that clade A and C members shared broadly overlapping expression signatures in root, stem, and leaf tissues, whereas clade B genes exhibited organ-prevalent patterns. When seedlings were treated with three monochromatic light regimes, the PpBPC family displayed heterogeneous transcriptional responses, with individual clades showing distinct wavelength sensitivities. In particular, PpBPC6 and PpBPC8 were strongly activated by blue light. Collectively, these data delineate the foundational landscape of the PpBPC family and highlight candidate members likely involved in light signal transduction, thereby establishing a framework for future mechanistic dissection of light-responsive gene regulation in P. praeruptorum.
It is demonstrated that heterologous expression of TksPLATZ1, TksPLATZ2 and TksPLATZ7 localize to the cell nucleus and act as transcriptional activators and repressors, respectively, which enhances the tolerance of Arabidopsis to salt and osmotic stress.
BACKGROUND Calcium-dependent protein kinases (CDPKs) serve as key sensors and transducers of intracellular calcium signals, playing crucial regulatory roles in diverse physiological processes. However, research on CDPK genes in Camellia nitidissima remains limited. RESULTS In this study, we identified 34 CDPK genes distributed across 15 chromosomes in the C. nitidissima genome. Phylogenetic analysis further classified the CDPK gene family into five distinct subfamilies. Promoter cis-element analysis revealed regulatory motifs associated with hormone responses, growth and development, and abiotic stress tolerance. Expression analysis revealed that six CnCDPKs are specifically and highly expressed in petals at the bud stage. In contrast, CnCDPK15/28/31/34 exhibited significantly elevated expression during the senescence phase, suggesting their potential role in petal aging. Eight CnCDPK genes were highly expressed in stamens, with CnCDPK18 showing the highest expression, implicating these genes in stamen development. Collectively, CnCDPK9 and CnCDPK30 responded rapidly to MeJA treatment, whereas CnCDPK3, CnCDPK23, and CnCDPK31 responded rapidly to ET treatment, suggesting that these genes are key regulatory in MeJA- and ET-mediated physiological responses, respectively. Both CnCDPK3 and CnCDPK31 were significantly upregulated by MeJA, ET, and GA₃, suggesting their key roles in hormone signal crosstalk. CONCLUSIONS Our study identified the CDPK gene family in C. nitidissima, providing new insights into its regulatory roles in floral organ development and hormone signaling.
