Special Issue Information

Dear Colleagues,

Forest trees play a crucial role in maintaining global ecological balance by contributing to carbon neutrality, preserving biodiversity, and providing raw materials for industry. The purpose of genetic breeding of forest trees is to develop superior varieties with higher yields, better quality, enhanced disease resistance, and improved adaptability to environmental changes, enabling forests to yield higher returns under the same management levels. However, due to the long growth and reproduction cycles of trees, the level of genetic improvement and utilization remains relatively low. Biotechnology offers powerful tools to accelerate the breeding process and introduce complex traits that are difficult to achieve through traditional breeding methods. By leveraging modern biotechnologies in conjunction with conventional breeding techniques, it is possible to shorten breeding cycles and accelerate the process of creating new varieties. This Special Issue of Plants will focus on the latest advancements and future directions of biotechnological applications in forest tree genetic breeding, including molecular marker technology, cell engineering technology, and gene engineering technology.

Parrotia subaequalis is a rare and endangered deciduous tree native to China, valued for its vibrant autumn foliage and ornamental appeal. Its leaves exhibit striking coloration, ranging from red to yellow and purple, yet the physiological and molecular mechanisms behind this variation remain poorly understood. Here, we combined transcriptomic, metabolomic, and physiological analyses to investigate pigment changes within the yellow leaf phenotype of P. subaequalis. Our findings revealed significant differences in gene expression and metabolic profiles between yellow and green leaves, particularly in starch and sucrose metabolism, photosynthesis, and carbon metabolism. Yellow leaves exhibited reduced photosynthetic capacity and carotenoid levels, alongside increased D-glucose concentration. These findings suggest that visible color transitions are likely driven by coordinated changes in carbohydrate metabolism, photosynthetic function, and organic compound accumulation. This study provides novel insights into the molecular and physiological mechanisms governing leaf pigmentation in an endangered tree, with useful information relevant to their conservation and sustainable utilization.
