Special Issue Information

Dear Colleagues,

We are delighted to announce a Special Issue of the journal Plants dedicated to Bioinformatics and Functional Genomics in Modern Plant Science. With an increasing number of available genome sequences across the plant kingdom, it has become imperative to unravel the genomic code and establish connections between functional sequences and phenotypes using bioinformatics methodologies. This Special Issue aims to offer a comprehensive overview of recent advancements and discoveries aimed at comprehending functional genomics within plants. We believe that this compilation of articles will make a significant contribution to the scientific community's comprehension of plant genetics and genomics, shedding light on its profound impacts on plant growth, development, and responses to environmental cues.

The BTB/POZ protein family is widely distributed across the biological kingdom, and its various subfamilies perform diverse physiological functions, including regulating plant growth and development, defending against pathogen invasion, participating in metabolic regulation, and responding to abiotic stresses. However, the functional roles of BTB genes in wood formation remain largely unknown. In this study, a total of 103 BTB genes were identified in Populus trichocarpa. Expression pattern analysis and β-glucuronidase (GUS) staining revealed that PtrBTB82 was predominantly expressed in the xylem. Overexpression of PtrBTB82 in P. trichocarpa significantly reduced cambial activity, resulted in a narrower xylem, and altered the chemical composition of the secondary cell wall, suggesting that PtrBTB82 plays the roles in wood formation. Quantitative real-time PCR (RT-qPCR) analysis showed that overexpression of PtrBTB82 suppressed the expression of genes related to the WUSCHEL-related pathway and plant hormone signaling, which may underlie the reduced cambial activity and inhibited xylem development. Moreover, genes associated with lignin biosynthesis (PtrPALs, PtrC4H1, Ptr4CL and PtrCAD1) were upregulated, while secondary wall cellulose synthase genes (PtrCESA7A/B and PtrCESA8A) were markedly downregulated in the overexpression lines, likely contributing to the altered chemical composition of the wood. Collectively, this study provides new insights into the role of PtrBTBs in wood formation, thereby revealing the functional diversity of the BTB family in plants. Full article

Chrysanthemum × morifolium is a commercially important flower worldwide. Chrysanthemum lavandulifolium is the main model plant for the research on Chrysanthemum. Enhancing stress resistance in C. lavandulifolium is highly significant for improving commercial chrysanthemum production. NAC transcription factors are key regulators of plant growth, development, and stress responses. In this study, we cloned ClVND1—a member of the OsNAC7 subfamily within the NAC transcription factor family—from Chrysanthemum lavandulifolium. The gene comprises a 1164 bp coding sequence (CDS) encoding a protein of 387 amino acids. Overexpression of ClVND1 promotes secondary cell wall thickening in the stems of transgenic Arabidopsis, stimulates lateral root growth, and consequently enhances tolerance to salt and low-temperature stress in seedlings. Phenotypic analysis showed that transgenic Arabidopsis exhibited reduced inflorescence elongation and plant height compared to wild-type controls, but an earlier flowering time. These findings suggest that ClVND1 enhances stress resistance by promoting lateral root development, while also suppressing inflorescence growth and accelerating flowering time. Full article
