Unlocking nature's (sub)cellular symphony: Phase separation in plant meristems
Curr Opin Plant Biol. 2023 Oct 18;76:102480. doi: 10.1016/j.pbi.2023.102480. Online ahead of print.ABSTRACTPlant development is based on the balance of stem cell maintenance and differentiation in the shoot and root meristems. The necessary cell fate decisions are regulated by intricate networks of proteins and biomolecules within plant cells and require robust and dynamic compartmentalization strategies, including liquid-liquid phase separation (LLPS), which allows the formation of membrane-less compartments. This review summarizes the current knowledge about the emerging field of LLPS in plant development, with a particu...

Tunable recurrent priming of lateral roots in Arabidopsis: More than just a clock?
Curr Opin Plant Biol. 2023 Oct 17;76:102479. doi: 10.1016/j.pbi.2023.102479. Online ahead of print.ABSTRACTLateral root (LR) formation in Arabidopsis is a continuous, repetitive, post-embryonic process regulated by a series of coordinated events and tuned by the environment. It shapes the root system, enabling plants to efficiently explore soil resources and adapt to changing environmental conditions. Although the auxin-regulated modules responsible for LR morphogenesis and emergence are well documented, less is known about the initial priming. Priming is characterised by recurring peaks of auxin signalling, which, once me...

Cellular and molecular basis of symbiotic nodule development
Curr Opin Plant Biol. 2023 Oct 17;76:102478. doi: 10.1016/j.pbi.2023.102478. Online ahead of print.ABSTRACTRoot nodule development plays a vital role in establishing the mutualistic relationship between legumes and nitrogen-fixing rhizobia. Two primary processes are involved in nodule development: formative cell divisions in the root cortex and the subsequent differentiation of nodule cells. The first process involves the mitotic reactivation of differentiated root cortex cells to form nodule primordium after perceiving symbiotic signals. The second process enables the nascent nodule primordium cells to develop into variou...

Till death do us pair: Co-evolution of plant-necrotroph interactions
Curr Opin Plant Biol. 2023 Oct 16;76:102457. doi: 10.1016/j.pbi.2023.102457. Online ahead of print.ABSTRACTPlants use programmed cell death as a potent defense response against biotrophic pathogens that require living host cells to thrive. However, cell death can promote infection by necrotrophic pathogens. This discrepancy creates specific co-evolutionary dynamics in the interaction between plants and necrotrophs. Necrotrophic pathogens produce diverse cell death-inducing effectors that act redundantly on several plant targets and sometimes suppress plant immune responses as an additional function. Plants use surface rece...

Developing for nutrient uptake: Induced organogenesis in parasitic plants and root nodule symbiosis
Curr Opin Plant Biol. 2023 Oct 10;76:102473. doi: 10.1016/j.pbi.2023.102473. Online ahead of print.ABSTRACTPlants have evolved diverse strategies to meet their nutritional needs. Parasitic plants employ haustoria, specialized structures that facilitate invasion of host plants and nutrient acquisition. Legumes have adapted to nitrogen-limited conditions by developing nodules that accommodate nitrogen-fixing rhizobia. The formation of both haustoria and nodules is induced by signals originating from the interacting organisms, namely host plants and rhizobial bacteria, respectively. Emerging studies showed that both organogen...

How to utilize comparative transcriptomics to dissect morphological diversity in plants
Curr Opin Plant Biol. 2023 Oct 5;76:102474. doi: 10.1016/j.pbi.2023.102474. Online ahead of print.ABSTRACTComparative transcriptomics has emerged as a powerful approach that allows us to unravel the genetic basis of organ morphogenesis and its diversification processes during evolution. However, the application of comparative transcriptomics in studying plant morphological diversity addresses challenges such as identifying homologous gene pairs, selecting appropriate developmental stages for comparison, and extracting biologically meaningful networks. Methods such as phylostratigraphy, clustering, and gene co-expression ne...
