The role of the chloroplast extends far beyond hosting photosynthesis; these organelles also serve as a regulatory hub for plant immunity. As a result, many plant pathogens, such as the barley stripe mosaic virus (BSMV) have evolved strategies to circumvent this immunity and exploit the chloroplast as a site of viral replication. A recent report […]
Wood is a major source of biomass on Earth and is valuable feedstock for multiple industries. Wood formation includes vascular cambium cell division and the maturation of the resulting stem-differentiating xylem (SDX) cells into mature xylem. Zhao et al. furthers our understanding of these processes by identifying and characterizing the function of PtrSHR1, a transcription […]
A natural antisense transcript (NAT) is a form of non-coding RNA that shares sequence complementarity with a protein coding sense gene. Although originally thought to be transcriptional noise, recent findings show that NATs contain functional roles, often through the regulation of their cognate sense transcripts. Work by Seo et al. has identified ELF18‐INDUCED LONG NONCODING […]
Elucidating the pathways in which plants can recognize and respond to heat stress is a key step in developing more resilient plants and crops. Work by Li et al. provides a more in-depth understanding of the early factors in heat stress-responsive (HSR) gene expression in Arabidopsis. They first identified BAM1 and PBS1, two Receptor-Like Kinases […]
