The potential role of vesicle transport-related small GTPases rabs in abiotic stress responses.

Rab GTPases are a class of small GTP-binding proteins, play crucial roles in the membrane transport machinery with in eukaryotic cells. They dynamically regulate the precise targeting and tethering of transport vesicles to specific compartments by transitioning between active and inactive states. In plants, Rab GTPases are classified into eight distinct subfamilies: Rab1/D, Rab2/B, Rab5/F, Rab6/H, Rab7/G, Rab8/E, Rab11/A, and Rab18/C.

Exploring the interplay between angiosperm chlorophyll metabolism and environmental factors.

In this review, we summarize how chlorophyll metabolism in angiosperm is affected by the environmental factors: light, temperature, metal ions, water, oxygen, and altitude. The significance of chlorophyll (Chl) in plant leaf morphogenesis and photosynthesis cannot be overstated. Over time, researchers have made significant advancements in comprehending the biosynthetic pathway of Chl in angiosperms, along with the pivotal enzymes and genes involved in this process, particularly those related to heme synthesis and light-responsive mechanisms.

Comparative transcriptome analysis of molecular mechanisms underlying adventitious root developments in Huangshan Bitter tea () under red light quality.

As the formation of adventitious roots (AR) is an important component of in vitro regeneration of tea plants, the propagation and preservation of Huangshan Bitter tea () cuttings have been hindered due to its lower rooting rate. As light is a crucial environmental factor that affects AR formation, this study aimed to investigate the special role of red light (RL) in the formation of AR in Huangshan Bitter tea plants, which has not been well understood. Huangshan Bitter tea plants were induced with white light (control, WL) and red light (660 nm, RL) qualities 36 days after induced treatment (DAI) to investigate dynamic AR formation and development, anatomical observation, hormones content change, and weighted gene co-expression network analysis (WGCNA) of the transcriptome.

Analysis of the complete chloroplast genomes of and (Lamiaceae).

Linn. is a perennial herb with about 300 species. This genus has high medicinal value and many are used in Traditional Chinese Medicine (TCM).

Assembly of the complete mitochondrial genome of an endemic plant, Scutellaria tsinyunensis, revealed the existence of two conformations generated by a repeat-mediated recombination.

We assembled the complete mitochondrial genome of Scutellaria tsinyunensis in this study. Repeat-mediated recombination resulted in the formation of two conformations of the mitochondrial genome in S. tsinyunensis.
