Special Issue Information

Dear Colleagues,

Tree breeding and genetic diversity are crucial for the sustainability and resilience of forest ecosystems. As environmental challenges intensify, the differentiation and conservation of tree genetic resources is becoming increasingly significant. This Special Issue aims to provide a comprehensive overview of recent advancements in tree breeding, focusing on the genetic diversity and differentiation necessary for robust forest management and conservation strategies.

The goal is to highlight the latest research findings and technological innovations that contribute to understanding and enhancing the genetic variability of tree species. We welcome contributions that explore diverse aspects of tree breeding, from molecular and genomic approaches to field-based studies, which elucidate the mechanisms driving genetic differentiation and adaptation. An emphasis will also be placed on strategies and practices that support the conservation of genetic resources, ensuring the long-term health and productivity of forest ecosystems.

Potential topics include, but are not limited to, the following:

- Genetic diversity and structure in tree populations;

- Molecular markers in tree breeding;

- Genomic selection and assisted breeding;

- Conservation genetics of forest trees;

- Impact of climate change on genetic diversity;

- Strategies for preserving rare and endangered tree species;

- Genetic differentiation and adaptation mechanisms.

This Special Issue seeks to gather cutting-edge research that will advance our knowledge and practices in tree breeding, genetic diversity and conservation, fostering resilient and thriving forest ecosystems.

Abstract
The genetic characteristics of postintroduced Metasequoia glyptostroboides from three forest areas in Ningbo Forest Farm, China, were analyzed by using polymorphic SSR markers. High genetic diversity at the species level (Na = 5.306, Ne = 3.411, I = 1.269, H [...] Read more.
The genetic characteristics of postintroduced Metasequoia glyptostroboides from three forest areas in Ningbo Forest Farm, China, were analyzed by using polymorphic SSR markers. High genetic diversity at the species level (Na = 5.306, Ne = 3.411, I = 1.269, Ho = 0.604 and He = 0.640) was detected. No significant difference in diversity was observed between mother trees and seedlings, indicating random mating or the absence of a founder effect. The group with the highest diversity was Shangliang seedlings (SLGS). Inbreeding was detected in two groups (SLGM and LXS), possibly due to biased sampling and selective pressures on these groups. AMOVA disclosed most genetic variation within groups (88%), with moderate differentiation (Fst = 0.117) and some gene flow (Nm = 1.887) between groups. Population structure analysis classified the six groups into distinct units, highlighting the need for tailored conservation strategies. These findings inform conservation and management practices for the introduced M. glyptostroboides. Full article
