Drought is a global threat that affects agricultural production. Plants have evolved several adaptive strategies to cope with drought. Stomata are essential structures for plants control water status and photosynthesis rate. Stomatal closure an efficient way reduce loss improve survivability under drought conditions. The opening of stomata depend on the turgor pressure in guard cells. Three key signaling molecules, including abscisic acid (ABA), reactive oxygen species (ROS), calcium ion (Ca2+), play pivotal roles controlling stomatal closure. sense water-deficit signal mainly via leaves roots. On one hand, ABA actively synthesized root leaf vascular tissues transported other roots synthesize CLAVATA3/EMBRYO-SURROUNDING REGION RELATED 25 (CLE25) peptide, which cells promote synthesis. perceived by pyrabactin resistance (PYR)/PYR1-like (PYL)/regulatory components receptor (RCAR) receptors, inactivate PP2C, resulting activating protein kinases SnRK2s.

Plant Hormone Transport and Localization: Signaling Molecules on the Move

Annual Review of Plant Biology, Год журнала: 2023, Номер 74(1), С. 453 - 479

Опубликована: Март 8, 2023

Plant hormones are a group of small signaling molecules produced by plants at very low concentrations that have the ability to move and function distal sites. Hormone homeostasis is critical balance plant growth development regulated multiple levels, including hormone biosynthesis, catabolism, perception, transduction. In addition, over short long distances regulate various developmental processes responses environmental factors. Transporters coordinate these movements, resulting in maxima, gradients, cellular subcellular sinks. Here, we summarize current knowledge most characterized transporters with respect biochemical, physiological, activities. We further discuss localizations transporters, their substrate specificities, need for same context development.

Understanding the regulation of cereal grain filling: The way forward

Journal of Integrative Plant Biology, Год журнала: 2023, Номер 65(2), С. 526 - 547

Опубликована: Янв. 17, 2023

Abstract During grain filling, starch and other nutrients accumulate in the endosperm; this directly determines yield quality crops such as rice ( Oryza sativa ), maize Zea mays wheat Triticum aestivum ). Grain filling is a complex trait affected by both intrinsic environmental factors, making it difficult to explore underlying genetics, molecular regulation, application of these genes for breeding. With development powerful genetic techniques, much has been learned about networks related over past decades. In review, we highlight key factors affecting including biological abiotic factors. We then summarize controlling their roles event, regulators sugar translocation biosynthesis, phytohormone‐related regulators, Finally, discuss how current knowledge valuable could be integrated with strategies breeding cereal varieties improved quality.

Highlights in gibberellin research: A tale of the dwarf and the slender

PLANT PHYSIOLOGY, Год журнала: 2024, Номер 195(1), С. 111 - 134

Опубликована: Янв. 30, 2024

It has been almost a century since biologically active gibberellin (GA) was isolated. Here, we give historical overview of the early efforts in establishing GA biosynthesis and catabolism pathway, characterizing enzymes for metabolism, elucidating their corresponding genes. We then highlight more recent studies that have identified receptors signaling components (DELLA repressors F-box activators), determined molecular mechanism DELLA-mediated transcription reprograming, revealed how DELLAs integrate multiple pathways to regulate plant vegetative reproductive development response internal external cues. Finally, discuss transporters roles GA-mediated development.

Harnessing Phytohormones: Advancing Plant Growth and Defence Strategies for Sustainable Agriculture

Physiologia Plantarum, Год журнала: 2024, Номер 176(3)

Опубликована: Май 1, 2024

Abstract Phytohormones, pivotal regulators of plant growth and development, are increasingly recognized for their multifaceted roles in enhancing crop resilience against environmental stresses. In this review, we provide a comprehensive synthesis current research on utilizing phytohormones to enhance productivity fortify defence mechanisms. Initially, introduce the significance orchestrating growth, followed by potential utilization bolstering defences diverse stressors. Our focus then shifts an in‐depth exploration mediating responses biotic stressors, particularly insect pests. Furthermore, highlight impact agricultural production while underscoring existing gaps limitations hindering widespread implementation practices. Despite accumulating body field, integration into agriculture remains limited. To address discrepancy, propose framework investigating intricate interplay between sustainable agriculture. This advocates adoption novel technologies methodologies facilitate effective deployment settings also emphasizes need through rigorous field studies. By outlining roadmap advancing agriculture, review aims catalyse transformative changes practices, fostering sustainability settings.

SWEET11b transports both sugar and cytokinin in developing barley grains

The Plant Cell, Год журнала: 2023, Номер 35(6), С. 2186 - 2207

Опубликована: Март 1, 2023

Abstract Even though Sugars Will Eventually be Exported Transporters (SWEETs) have been found in every sequenced plant genome, a comprehensive understanding of their functionality is lacking. In this study, we focused on the SWEET family barley (Hordeum vulgare). A radiotracer assay revealed that expressing HvSWEET11b African clawed frog (Xenopus laevis) oocytes facilitated bidirectional transfer not only just sucrose and glucose, but also cytokinin. Barley plants harboring loss-of-function mutation could set viable grains, while distribution cytokinin was altered developing grains which gene knocked down. Sucrose allocation within transgenic disrupted, consistent with changes to gradient across as visualized by magnetic resonance imaging Fourier transform infrared spectroscopy microimaging. Decreasing expression reduced overall grain size, sink strength, number endopolyploid endosperm cells, contents starch protein. The control exerted over sugars cytokinins likely predetermines synergy, resulting adjustments grain's biochemistry transcriptome.

Cell-to-cell communication is fundamental to multicellular organisms and unicellular living in a microbiome. It thought have evolved as stress- or quorum-sensing mechanism organisms. A unique cell-to-cell that uses reactive oxygen species (ROS) signal (termed the “ROS wave”) was identified flowering plants. This process essential for systemic signaling plant acclimation stress can spread from small group of cells entire within minutes. Whether similar found other however unknown. Here, we report ROS wave be algae, amoeba, ferns, mosses, mammalian cells, isolated hearts. We further show this triggered by local H 2 O treatment blocked application catalase NADPH oxidase inhibitors algae it communicates important stress–response signals between cells. Taken together, our findings suggest an active signaling, like wave, before diverged. could communicated environmental coordinated response many different community.
