Curr Opin Plant Biol. 2023 Sep 14:102445. doi: 10.1016/j.pbi.2023.102445. Online ahead of print.ABSTRACTPlants have evolved robust adaptive mechanisms to withstand the ever-changing environment. Tightly regulated distribution of the hormone auxin throughout the plant body controls an impressive variety of developmental processes that tailor plant growth and morphology to environmental conditions. The proper flow and directionality of auxin between cells is mainly governed by asymmetrically localized efflux carriers - PINs - ensuring proper coordination of developmental processes in plants.

The stomatal fates: Understanding initiation and enforcement of stomatal cell fate transitions
Curr Opin Plant Biol. 2023 Sep 12:102449. doi: 10.1016/j.pbi.2023.102449. Online ahead of print.ABSTRACTIn the stomatal lineage, repeated arcs of initiation, stem-cell proliferation, and terminal cell fate commitment are displayed on the surface of aerial organs. Over the past two decades, the core transcription and signaling elements that guide cell divisions, patterning, and fate transitions were defined. Here we highlight recent work that extends the core using a variety of cutting-edge techniques in different plant species. New work has discovered transcriptional circuits that initiate and reinforce stomatal fate trans...

Illuminating the path to shoot meristem regeneration: Molecular insights into reprogramming cells into stem cells
Curr Opin Plant Biol. 2023 Sep 13:102452. doi: 10.1016/j.pbi.2023.102452. Online ahead of print.ABSTRACTPlant cells possess the ability to dedifferentiate and reprogram into stem cell-like populations, enabling the regeneration of new organs. However, the maintenance of stem cells relies on specialized microenvironments composed of distinct cell populations with specific functions. Consequently, the regeneration process necessitates the orchestrated regulation of multiple pathways across diverse cellular populations. One crucial pathway involves the transcription factor WUSCHEL HOMEOBOX 5 (WOX5), which plays a pivotal role...

Evolution of immunity networks across embryophytes
Curr Opin Plant Biol. 2023 Sep 11:102450. doi: 10.1016/j.pbi.2023.102450. Online ahead of print.ABSTRACTLand plants (embryophytes), including vascular (tracheophytes) and non-vascular plants (bryophytes), co-evolved with microorganisms since descendants of an algal ancestor colonized terrestrial habitats around 500 million years ago. To cope with microbial pathogen infections, embryophytes evolved a complex immune system for pathogen perception and activation of defenses. With the growing number of sequenced genomes and transcriptome datasets from algae, bryophytes, tracheophytes, and available plant models, comparative an...

Innovations in two genes kickstarted the evolution of nitrogen-fixing nodules
Curr Opin Plant Biol. 2023 Sep 9:102446. doi: 10.1016/j.pbi.2023.102446. Online ahead of print.ABSTRACTThe root nodule symbiosis between plants and nitrogen-fixing bacteria is a fascinating trait limited to several plant species. Given the agronomic potential of transferring this symbiosis to nonleguminous crops, the symbiosis has attracted researchers' attention for over a century. The origins of this symbiosis can be traced back to a single ancestor, around 110 million years ago. Recent findings have uncovered that adaptations in a receptor complex and the recruitment of the transcription factor Nodule Inception (NIN) ar...

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...
