The photoreceptor CRY1 interacts directly with both GID1 and DELLA proteins in a blue light-dependent manner to competitively inhibit the GID1-DELLA interaction, thereby stabilizing DELLA proteins and enhancing their repression of plant growth.

The virulence effector IPI-O4 blocks NLR RB-mediated recognition of its cognate effector IPI-O1 by suppressing the self-association of both the RB coiled-coil domain and IPI-O1. IPI-O1 and IPI-O4 exhibit striking differences in subcellular localization, self-association status, and effects on RB self-association. IPI-O4 probably sequesters the RB-IPI-O1 complex and subsequently blocks…

Transcription factors (TFs) regulate gene expression by recognizing regulatory sequences in the promoters of target genes. This study reports the investigation of the DNA-binding specificities of the bHLH MYC2-related proteins and demonstrates that specific sequence modules flanking the binding site are essential for TF recognition. It concludes that different bHLHs may have their own codes for…

This study demonstrates the function of two MADS-box genes in secondary growth and reveals a molecular mechanism that modulates subcellular auxin homeostasis in the vascular cambium area, which in turn regulates cambium proliferation activity in Populus.

The astounding chemodiversity of terpenoids is mainly ascribed to diverse terpenoid synthases. This study reports the characterization of an extremely promiscuous terpenoid synthase from the Lamiaceae plant Colquhounia coccinea var. mollis. It accepts C25/C20/C15/C10 substrates to generate a panel of sester-/di-/sesqui-/mono-terpenoids, including three previously undescribed terpenoids: two…

The complex intracellular compartmentation of JA synthesis, metabolism, and signaling provides a new regulatory layer for coordinating JA metabolic flux and signaling dynamics. A number of transporters located at endomembranes and the plasma membrane constitute a network that facilitates the transport of JAs. Here, the metabolism, signaling, and transport of JAs are reviewed through the lens of…

This review summarizes recent progress in plant sphingolipid metabolism, diversity, distribution, trafficking, and function. The intersections among these topics are also discussed, then current challenges and issues in the study of plant sphingolipids are highlighted.

This review introduces the sesterterpenes (C25), including the plant species that produce them and their potential bioactivities. Then, recent findings in plant sesterterpene biosynthesis are reviewed, with a particular focus on geranylfarnesyl diphosphate synthase and sesterterpene synthase.
