Background: Assessing the current status and identifying the mechanisms threatening endangered plants are significant challenges and fundamental to biodiversity conservation, particularly for protecting Tertiary relict trees and plant species with extremely small populations (PSESP). Ulmus elongata (Ulmus, Ulmaceae) with high values for the ornamental application, is a Tertiary relict tree species and one of the members from PSESP in China. Currently, the wild populations of U.

Article Synopsis
- Paperbark maple (Acer griseum) is an endangered plant in China, known for its striking red autumn leaves, but research on its leaf color change is limited.
- This study investigates the physiological and molecular processes behind the leaf color transformation by analyzing changes in chlorophyll, carotenoids, and levels of anthocyanidins across three stages: green, half-red, and red.
- Findings indicate that the compound cyanidin-3,5-O-diglucoside is likely responsible for the leaf reddening, and the research also identifies key transcription factors that regulate anthocyanin biosynthesis, which could inform breeding strategies for the species.

, a key tropical and subtropical economic tree in the Oxalidaceae family, is distinguished by its unique pentagram-shaped fruit. This study investigates the developmental processes shaping the polarity of fruit and their underlying hormonal and genetic mechanisms. By analyzing the Y1, Y2, and Y3 developmental stages-defined by the fruit diameters of 3-4 mm, 4-6 mm, and 6-12 mm, respectively-we observed that both cell number and cell size contribute to fruit development.

A new synergistic approach of classical conservation strategies combined with advanced assisted reproduction technologies (aART) allows for protection and rescue of endangered keystone species at the brink of extinction, which can help to safeguard complex ecosystems. Reproduction biology and management in mammal species is not only challenging in regards to their diverging sizes, anatomy, and often unknown physiology; it also requires customized training or chemical restraint protocols for safe handling. Besides these general challenges, there are several new assisted reproduction techniques (ART) specifically tailored to critically endangered mammals.
