Molecular Interactions Between Plants and Insect Herbivores

Annual Review of Plant Biology, Journal Year: 2019, Volume and Issue: 70(1), P. 527 - 557

Published: Feb. 20, 2019

Diverse molecular processes regulate the interactions between plants and insect herbivores. Here, we review genes proteins that are involved in plant–herbivore discuss how their discovery has structured current standard model of interactions. Plants perceive damage-associated and, possibly, herbivore-associated patterns via receptors activate early signaling components such as Ca 2+ , reactive oxygen species, MAP kinases. Specific defense reprogramming proceeds networks include phytohormones, secondary metabolites, transcription factors. Local systemic regulation toxins, proteins, physical barriers, tolerance traits protect against Herbivores counteract plant defenses through biochemical deactivation, effector-mediated suppression signaling, chemically controlled behavioral changes. The basis is now well established for systems. Expanding approaches to unexplored dimensions plant–insect should be a future priority.

Rapid Responses to Abiotic Stress: Priming the Landscape for the Signal Transduction Network

Trends in Plant Science, Journal Year: 2018, Volume and Issue: 24(1), P. 25 - 37

Published: Nov. 3, 2018

Plants grow and reproduce within a highly dynamic environment that can see abrupt changes in conditions, such as light intensity, temperature, humidity, or interactions with biotic agents. Recent studies revealed plants respond seconds to some of these engaging many different metabolic molecular networks, well rapidly altering their stomatal aperture. Some rapid responses were further shown propagate throughout the entire plant via waves reactive oxygen species (ROS) Ca2+ are possibly mediated through vascular system. Here, we propose integration signals is pulses gene expression coordinated systemic manner by ROS/Ca+2 waves.

Systemic signaling during abiotic stress combination in plants

Proceedings of the National Academy of Sciences, Journal Year: 2020, Volume and Issue: 117(24), P. 13810 - 13820

Published: May 29, 2020

Extreme environmental conditions, such as heat, salinity, and decreased water availability, can have a devastating impact on plant growth productivity, potentially resulting in the collapse of entire ecosystems. Stress-induced systemic signaling acquired acclimation play canonical roles survival during episodes stress. Recent studies revealed that response to single abiotic stress, applied leaf, plants mount comprehensive stress-specific includes accumulation many different transcripts metabolites, well coordinated whole-plant stomatal response. However, nature are routinely subjected combination two or more stresses, each triggering its own response, highlighting new fundamental question biology: capable integrating signals simultaneously generated conditions stress combination? Here we show integrate combination, manner which sense stresses trigger these (i.e., at same parts plant) makes significant difference how fast efficient they induce reactive oxygen species (ROS) signals; transcriptomic, hormonal, responses; acclimation. Our results shed light acclimate their environment survive stresses. In addition, highlight key role for ROS coordinating leaves

Distinct identities of leaf phloem cells revealed by single cell transcriptomics

The Plant Cell, Journal Year: 2021, Volume and Issue: 33(3), P. 511 - 530

Published: Jan. 1, 2021

The leaf vasculature plays a key role in solute translocation. Veins consist of at least seven distinct cell types, with specific roles transport, metabolism, and signaling. Little is known about vascular cells, particular the phloem parenchyma (PP). PP effluxes sucrose into apoplasm as basis for loading, yet has been characterized only microscopically. Here, we enriched cells from Arabidopsis leaves to generate single-cell transcriptome atlas vasculature. We identified 19 clusters, encompassing epidermis, guard hydathodes, mesophyll, all used metabolic pathway analysis define their roles. Clusters comprising were transporters, including SWEET11 SWEET12 UmamiT amino acid efflux carriers. provide evidence that development occurs independently ALTERED PHLOEM DEVELOPMENT, transcription factor required differentiation. have unique pattern metabolism activity companion (CCs), explaining differential distribution/metabolism acids veins. kinship relation clusters strikingly similar vein morphology, except clear separation CC other PP. In summary, our RNA-sequencing provides wide range information relationship types.

Plants in nature are constantly exposed to organisms that touch them and wound them. A highly conserved response these stimuli is a rapid collapse of membrane potential (i.e. decrease electrical field strength across membranes). This can be coupled the production and/or action jasmonate or ethylene. Here, various types signals plants discussed context hormone responses. Genetic approaches revealing genes involved wound-induced signalling. These include clade 3 GLUTAMATE RECEPTOR-LIKE (GLR) genes, Arabidopsis H+ -ATPases (AHAs), RESPIRATORY BURST OXIDASE HOMOLOGUEs (RBOHs), determine cell wall properties.

Calcium (Ca 2+ ) is a unique mineral that serves as both nutrient and signal in all eukaryotes. To maintain Ca homeostasis for nutrition signaling purposes, the tool kit transport has expanded across kingdoms of eukaryotes to encode specific signals referred signatures.
