At the root of plant symbioses: Untangling the genetic mechanisms behind mutualistic associations
Curr Opin Plant Biol. 2023 Sep 26:102448. doi: 10.1016/j.pbi.2023.102448. Online ahead of print.ABSTRACTMutualistic interactions between plants and microorganisms shape the continuous evolution and adaptation of plants such as to the terrestrial environment that was a founding event of subsequent life on land. Such interactions also play a central role in the natural and agricultural ecosystems and are of primary importance for a sustainable future. To boost plant's productivity and resistance to biotic and abiotic stresses, new approaches involving associated symbiotic organisms have recently been explored. New discoverie...

Specificity and breadth of plant specialized metabolite-microbe interactions
Curr Opin Plant Biol. 2023 Sep 22:102459. doi: 10.1016/j.pbi.2023.102459. Online ahead of print.ABSTRACTPlant specialized metabolites shape plant interactions with the environment including plant-microbe interactions. While we often group compounds into generic classes, it is the precise structure of a compound that creates a specific role in plant-microbe or-pathogen interactions. Critically, the structure guides definitive targets in individual interactions, yet single compounds are not limited to singular mechanistic targets allowing them to influence interactions across broad ranges of attackers, from bacteria to fungi...

Curr Opin Plant Biol. 2023 Sep 22:102454. doi: 10.1016/j.pbi.2023.102454. Online ahead of print.ABSTRACTC4 photosynthesis is more efficient than C3 photosynthesis for two reasons. First, C4 plants have evolved efficient C4 enzymes to suppress wasteful photorespiration and enhance CO2 fixation. Second, C4 leaves have Kranz anatomy in which the veins are surrounded by one layer of bundle sheath (BS) cells and one layer of mesophyll (M) cells. The BS and M cells are functionally well differentiated and also well coordinated for rapid assimilation of atmospheric CO2 and transport of photo-assimilates between the two types of c...

Whispers in the dark: Signals regulating underground plant-plant interactions
Curr Opin Plant Biol. 2023 Sep 21:102456. doi: 10.1016/j.pbi.2023.102456. Online ahead of print.ABSTRACTPlants are able to actively detect and respond to the presence in neighboring plants, in order to optimize their physiology to promote survival and reproduction despite the presence of competing organisms. A key but still poorly understood mechanism for neighbor detection is through the perception of root exudates. In this review, we explore recent findings on the role of root exudates in plant-plant interactions, focusing both on general interactions and also the highly specialized example of root parasite-host plant in...

Structural insights of cell wall integrity signaling during development and immunity
Curr Opin Plant Biol. 2023 Sep 20:102455. doi: 10.1016/j.pbi.2023.102455. Online ahead of print.ABSTRACTA communication system between plant cells and their surrounding cell wall is required to coordinate development, immunity, and the integration of environmental cues. This communication network is facilitated by a large pool of membrane- and cell-wall-anchored proteins that can potentially interact with the matrix or its fragments, promoting cell wall patterning or eliciting cellular responses that may lead to changes in the architecture and chemistry of the wall. A mechanistic understanding of how these receptors and ce...

Hormonal regulation of inflorescence and intercalary meristems in grasses
Curr Opin Plant Biol. 2023 Sep 20:102451. doi: 10.1016/j.pbi.2023.102451. Online ahead of print.ABSTRACTHormones played a fundamental role in improvement of yield in cereal grasses. Natural variants affecting gibberellic acid (GA) and auxin pathways were used to breed semi-dwarf varieties of rice, wheat, and sorghum, during the "Green Revolution" in the 20th century. Since then, variants with altered GA and cytokinin homeostasis have been used to breed cereals with increased grain number. These yield improvements were enabled by hormonal regulation of intercalary and inflorescence meristems. Recent advances have highlighte...

Regulation of PIN polarity in response to abiotic stress
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. Discerning the molecular players ...
