Special Issue Information

Dear Colleagues,

This Special Issue, “Molecular Markers in Forest Management and Tree Breeding”, refers to the use of genetic techniques, specifically the use of molecular markers, to improve the management and breeding of forest tree populations. This Issue aims to identify specific genetic traits that are associated with important characteristics, such as disease resistance, growth rate, and wood quality, as well as the use of marker-assisted selection to improve the efficiency of tree breeding programs. This Special Issue will likely include articles discussing the latest research and advances in this field, as well as case studies and practical applications of molecular markers in forest management and tree breeding.

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. Forests 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 2600 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.

Chinese pine (Pinus tabuliformis) is a conifer species endemic to the temperate, warm temperate, and semi-arid regions of China. It has important ecological and economic values, but lacks suitable molecular markers for genetic studies. In this study, we collected open-pollinated progeny seeds from four provenances: Ningcheng (Nc), Qinyuan (Qy), Weichang (Wc), and Pingquan (Pq). We sequenced the transcriptomes of open-pollinated progeny seedlings from four provenances and annotated 18,244 unigenes. We analyzed the expression of genes involved in the auxin indole-3-acetic acid (IAA), cytokinin (CTK), and gibberellin (GA) signaling pathways among the provenances. Additionally, we detected 2811 expressed sequence tag simple sequence repeat (EST-SSR) loci in 2360 unigenes, with a frequency of 14.83% and an average of one locus per 14,556 base pairs (bp). We developed 10 polymorphic primers from 67 pairs and tested them on 56 samples from the four provenances. These primers exhibited moderate to high polymorphism and distinguished all samples clearly. Our study reveals variation in growth and development among open-pollinated progeny seedlings from different provenances of Chinese pine and provides novel markers for its genetic diversity study and marker-assisted breeding.

Toona sinensis is an important “vegetable and timber” tree species that is widely distributed in eastern and southeastern Asia. An efficient mechanism for preserving and utilizing germplasm resources is crucial for speeding up the process of genetic improvement of T. sinensis. We collected a total of 1040 germplasm resources of T. sinensis from China, Britain, and New Zealand. Using a total of 27,040 markers, we analyzed the genetic diversity, genetic structure, and core collection of these resources. Additionally, a comprehensive evaluation method for phenotypes of T. sinensis was established by principal component analysis (PCA) and the technique for order preference by similarity to ideal solution (TOPSIS). Our analysis included three main results: Firstly, the breeding population, consisting of a total of 1040 individuals, contains a diverse genetic pool and can be divided into two genetic clusters. Secondly, the best core collection was obtained from the alternative population, consisting of a total of 208 individuals and comprising 20% of the breeding population. It was screened out based on Core Hunter 3 software with the average entry-to-nearest-entry (E-NE) algorithm. Finally, a comprehensive evaluation method was established based on eight selected agronomic traits of the core collection. This method allowed us to screen the best individual plants of the core collection, including N0237, N0972, and N0409. Overall, our research findings will enable better preservation and utilization of T. sinensis germplasm resources and result in faster improvement of T. sinensis varieties. Full article
