Unraveling the role of tRNA thiolation in translation control for plant immunity
Plant Science Research WeeklyThiolation of tRNA adds a sulfur-containing nucleotide modification at the tRNA wobble position, which is necessary for efficient translation. Zheng et al. investigated the role of tRNA thiolation in plant immunity, revealing its necessity for robust defense responses in Arabidopsis. They identified…
The Plant Cell Focus Issue: Biomolecular Condensates
Plant Science Research WeeklyThe September issue of The Plant Cell includes a focus on biomolecular condensates. Although the term “biomolecular condensates” is relatively new, it actually reflects a convergence and synthesis of several distinct threads of research. Biomolecular condensates span from “classic” membraneless…
18S rRNA processing factors in maize

Upstream ORFs check undesired leaky protein translation and buffer noise (Nature Plants)
Plant Science Research WeeklyDuring my research journey, I have come across a handful of genes that are hard to express. Sometimes, even with a strong promoter and high transcript level, the protein level is negligible. We generally considered these proteins might be degrading very fast. But maybe not. A recent article by Wu et…
LARP6C reveals its double face during plant fertilization
The Plant Cell: In a NutshellBilley et al. uncover the roles of LARP6C as a translational repressor in dormant pollen and an activator when the pollen “awakens”. The Plant Cell (2021) https://doi.org/10.1093/plcell/koab131
