Special Issue Information

Dear Colleagues,

Wood plays a crucial role in the growth and survival of plants by providing support, protection, and storage functions, as well as being a vital resource for human life. Understanding the molecular mechanisms of wood development is essential for advancing our knowledge of the formation and properties of wood, improving the quality and yield of forest trees, and promoting the development of the wood industry.

In recent years, advances in molecular biology and omics technologies have enriched our understanding of the fundamental processes and regulatory networks involved in plant development. The application of gene editing technologies enables scientists to precisely manipulate plant genes, thereby are expected to drive future progress in plant breeding and genetic improvement. Certainly, these breakthroughs helped us study tree-specific traits such as wood formation.

This special issue intends to bring forward the latest research in genetic and environmental/hormonal signals regulation of wood development across different tree species, discussing the molecular mechanisms that determine cambial development, vascular tissue formation, and cell wall biosynthesis. All types of original papers, such as original research articles and reviews, are welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

As an important timber genus with high economic and ecological values, Populus is a model for dissecting the genetic architecture of growth traits in perennial forest trees. However, the genetic mechanisms of longitudinal growth traits in poplar remain incompletely understood. In this study, we conducted longitudinal genetic analysis of height and diameter at breast height (DBH) in eleven-year poplar clones using ultra-deep sequencing datasets. We compared four S-shaped growth models, including asymptotic, Gompertz, logistic, and Richard, on eleven-year height and DBH records in terms of five metrics. We constructed the best-fitting growth model (Richard) and determined poplar ontogenetic stages by virtue of growth curve fitting and likelihood ratio testing. This study provides some scientific clues for temporal variation of longitudinal growth traits in Populus species. Full article
