Special Issue Information

Dear Colleagues,

Woody plants represent a diverse group of botanical organisms characterized by the development of persistent lignified tissues. The genetic and molecular breeding of woody plants has become an essential field of research in horticulture and forestry. These plants come in the form of a wide range of species, such as trees and shrubs, and are valued for their economic, ecological, and aesthetic significance. Breeding techniques are used to enhance the genetic characteristics of woody plants, aiming to develop varieties with improved traits like disease resistance, growth rate, wood quality, and fruit production. These efforts often involve the manipulation of genes and the exploration of the molecular basis of desirable traits, ultimately contributing to the sustainability and productivity of forest resources and the ornamental horticulture industry.

With this goal in mind, this Special Issue aims to assemble the latest advancements in comprehending the genetics and breeding of woody plants. We welcome research articles for this Special Issue, focusing on a wide range of topics, including (but not limited to) genetic analysis on the enhanced breeding characteristics of woody plants, molecular function elucidation, gene regulatory mechanisms, gene family evolution, expression regulation networks, as well as research related to plant physiology and plant phenomics, and the utilization of high-throughput data in the context of woody plants.

Torreya grandis, an economically significant evergreen tree species exclusive to subtropical China, is highly valued for its seeds. However, the seed development process of T. grandis remains relatively unexplored. Given the pivotal role WRKY transcription factors (TFs) play in coordinating diverse cellular and biological activities, as well as crucial signaling pathways essential for plant growth and development, and the lack of comprehensive investigation into their specific functions in T. grandis, our study investigated its genome and successfully isolated 78 WRKY genes and categorized them into three distinct clades. A conserved motif analysis unveiled the presence of the characteristic WRKY domain in each identified TgWRKY protein. The examination of gene structures revealed variable numbers of introns (ranging from zero to eight) and exons (ranging from one to nine) among TgWRKY genes. A chromosomal distribution analysis demonstrated the presence of TgWRKY across eight chromosomes in T. grandis. Tissue-specific expression profiling unveiled distinctive patterns of these 78 TgWRKY genes across various tissues. Remarkably, a co-expression analysis integrating RNA-seq data and morphological assessments pinpointed the pronounced expression of TgWRKY25 during the developmental stages of T. grandis seeds. Moreover, a KEGG enrichment analysis, focusing on genes correlated with TgWRKY25 expression, suggested its potential involvement in processes such as protein processing in the endoplasmic reticulum, starch, and sucrose metabolism, thereby modulating seed development in T. grandis. These findings not only underscore the pivotal role of WRKY genes in T. grandis seed development but also pave the way for innovative breeding strategies. Full article
