Special Issue Information

Dear Colleagues,

This Special Issue aims to provide an overview of the most recent advances in the field of adaptation mechanisms of forest trees to abiotic stress. Abiotic stresses, such as drought, salinity, and cold, are the main environmental stresses that adversely affect tree growth and thereby play a crucial role in determining forest productivity and the geographic distribution of tree species. Tree responses and tolerance to abiotic stress are complex biological processes, which can be better understood by employing genetic, genomic, metabolomic, and phenomic approaches to analyze them at a systems level. This will expedite the dissection of stress-sensing and signaling networks to further support efficient genetic improvement programs for forest trees. Moreover, the enormous genetic diversity for stress tolerance exists within some forest tree species, and the molecular genetic basis for this diversity has been rapidly unfolding in recent years, thanks to advances in sequencing technologies. In addition, the use of emerging phenotyping technologies extends the suite of traits that can be measured and will provide us with a better understanding of stress tolerance. The elucidation of abiotic stress tolerance mechanisms will enable the effective pyramiding of multiple tolerances in a single tree through genetic engineering. In this Special Issue, we will collect recent progress in the molecular basis of abiotic stress tolerance in forest trees and discuss the recommendations for future work.

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. Biology is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). 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.

Abstract
(1) Background: WOX (WUSCHEL-related homologous box) is a plant-specific transcription factor involved in plant development and stress response. It has been reported to be involved in processes such as growth and development, stem cell division and differentiation, and organ development; (2) Methods: In [...] Read more.
(1) Background: WOX (WUSCHEL-related homologous box) is a plant-specific transcription factor involved in plant development and stress response. It has been reported to be involved in processes such as growth and development, stem cell division and differentiation, and organ development; (2) Methods: In this study, bioinformatics was used to identify and analyze the WOX gene family of Korean pine. The gene characteristics were identified and analyzed through yeast transcriptional activation assays as well as subcellular localization experiments; (3) Results: A total of 21 members of the WOX gene family of Korean pine were identified in this study. The phylogenetic tree divides the PkWOX genes into three sub-branches. 21 PkWOX genes are unevenly distributed on 7 of the 12 chromosomes. PkWOX16 was expressed in all tissues. PkWOX2, 3 had higher expression in the embryonic callus, non-embryonic callus, somatic embryo, and zygotic embryo. PkWOX2, 3 and 16 were located in the nucleus and in the cell membrane. The PkWOX2 and 3 proteins exhibited transcriptional self-activation activity, while PkWOX16 did not; (4) Conclusions: In this study, the members of the WOX transcription factor family in Korean pine were identified and systematically analyzed, laying a foundation for their subsequent functional research.
