Special Issue Information

Dear Colleagues,

Abiotic stresses such as drought, salinity, and extreme temperatures trigger multilayered regulatory networks in plants, including photosynthetic modulation, stress sensing, signal transduction, and long-term adaptive remodelling. These stresses not only restrict plant growth but also profoundly influence forest productivity and the geographic distribution of tree species. This Special Issue highlights two research areas: the regulation of leaf plasticity and molecular breeding, with particular emphasis on the unique value of woody plants in stress-adaptation studies. Trees possess unique characteristics, including longevity, structural complexity, and heightened environmental sensitivity.  These traits lead to distinctive response patterns, such as photosynthetic regulation and stress memory, which establish trees as ideal models for investigating long-term adaptation. Advances in genomics, transcriptomics, metabolomics, and high-throughput phenotyping have greatly accelerated the dissection of stress-response networks, offering new opportunities for photosynthesis optimization, discovering stress‑adaptive genes, and intelligent breeding strategies.

This Special Issue aims to bring together cutting-edge research on photosynthesis dynamics, physiological and molecular mechanisms, and breeding innovations in woody plants under abiotic stresses. By integrating photosynthesis research, ecological physiology, and molecular breeding, we seek to provide scientific insights supporting sustainable forestry in a changing climate.

Cold sensitivity restricts the natural distribution of subtropical evergreen trees. In a representative species such as Phoebe bournei, evaluating physiological divergence among provenances is therefore essential for identifying cold-hardy germplasm and understanding adaptive evolution. This study investigated the photosynthetic capacity, redox homeostasis, and carbon metabolism of saplings from three provenances (WY, AF, and SC) under chilling stress and subsequent recovery. The results showed that low temperature significantly inhibited the net photosynthetic rate and photochemical efficiency in all saplings through predominant non-stomatal limitations. The northern provenance WY prioritized structural integrity and redox homeostasis by enhancing cyclic electron flow and timely antioxidant activation. The mid-latitude provenance AF demonstrated higher physiological plasticity and achieved more rapid recovery of photosynthetic activity upon rewarming. In contrast, the southern provenance SC was highly sensitive to chilling stress, exhibiting disrupted energy dissipation, severe lipid peroxidation, and impaired coordination of carbon metabolism and hormonal regulation. Overall, the pronounced divergence in adaptive strategies among provenances is evident. These findings provide a physiological basis for understanding intraspecific variation in P. bournei and offer guidance for germplasm selection under climate change. Full article
