Improving RNA-based crop protection through nanotechnology and insights from cross-kingdom RNA trafficking
Curr Opin Plant Biol. 2023 Sep 9:102441. doi: 10.1016/j.pbi.2023.102441. Online ahead of print.ABSTRACTSpray-induced gene silencing (SIGS) is a powerful and eco-friendly method for crop protection. Based off the discovery of RNA uptake ability in many fungal pathogens, the application of exogenous RNAs targeting pathogen/pest genes results in gene silencing and infection inhibition. However, SIGS remains hindered by the rapid degradation of RNA in the environment. As extracellular vesicles are used by plants, animals, and microbes in nature to transport RNAs for cross-kingdom/species RNA interference between hosts and micr...

SERKs and NIKs: Coreceptors or signaling hubs in a complex crosstalk between growth and defense?
Curr Opin Plant Biol. 2023 Sep 8:102447. doi: 10.1016/j.pbi.2023.102447. Online ahead of print.ABSTRACTSOMATIC EMBRYOGENESIS RECEPTOR-LIKE KINASES (SERKs) and NUCLEAR SHUTTLE PROTEIN-INTERACTING KINASES (NIKs) belong to superfamily II of leucine-rich repeat receptor-like kinases, which share cytosolic kinase conservation and a similar ectodomain configuration. SERKs have been extensively demonstrated to function as coreceptors of receptor-like kinases, which sense biotic or developmental signals to initiate specific responses. NIKs, on the other hand, have emerged as downstream components in signaling cascades, not functio...

Complex peptide hormone signaling in plant stem cells
Curr Opin Plant Biol. 2023 Sep 4;75:102442. doi: 10.1016/j.pbi.2023.102442. Online ahead of print.ABSTRACTPeptide hormones influence diverse aspects of plant development through highly coordinated cell-cell signaling pathways. Many peptide hormone families play key roles in stem cell maintenance across land plants. In this review, we focus on recent work in two conserved peptide hormone families, CLAVATA3/EMBRYO-SURROUNDING REGION (CLEs) and ROOT MERISTEM GROWTH FACTOR (RGFs), and their roles in regulating plant stem cells. We discuss recent work establishing downstream crosstalk between peptide hormones and other conserve...

Rapid auxin signaling: Unknowns old and new
Curr Opin Plant Biol. 2023 Sep 2;75:102443. doi: 10.1016/j.pbi.2023.102443. Online ahead of print.ABSTRACTTo respond to auxin, the chief orchestrator of their multicellularity, plants evolved multiple receptor systems and signal transduction cascades. Despite decades of research, however, we are still lacking a satisfactory synthesis of various auxin signaling mechanisms. The chief discrepancy and historical controversy of the field is that of rapid and slow auxin effects on plant physiology and development. How is it possible that ions begin to trickle across the plasma membrane as soon as auxin enters the cell, even thou...

Organogenic events during gynoecium and fruit development in Arabidopsis
Curr Opin Plant Biol. 2023 Aug 24;75:102440. doi: 10.1016/j.pbi.2023.102440. Online ahead of print.ABSTRACTAngiosperms are the most successful group of land plants. This success is mainly due to the gynoecium, the innermost whorl of the flower. In Arabidopsis, the gynoecium is a syncarpic structure formed by two congenitally fused carpels. At the fusion edges of the carpels, the carpel margin meristem forms. This quasi-meristem is important for medial-tissue development, including the ovules. After the double fertilization, both the seeds and fruit begin to develop. Due to the importance of seeds and fruits as major food s...
