ABSTRACT Owing to its detrimental effect on plant growth, salinity is an increasing worldwide problem for agriculture. To understand the molecular mechanisms activated in response salt Arabidopsis thaliana, we investigated Catharanthus roseus receptor-like kinase 1-like family, which contains sensors that were previously shown be involved sensing structural integrity of cell walls. We found herk1 the1-4 double mutants, lacking function HERKULES1 (HERK1) and combined with a gain-of-function...
Acclimation of root growth is vital for plants to survive salt stress. Halophytes are great examples that thrive even under severe salinity, but their tolerance mechanisms, especially those mediated by responses, still largely unknown. We compared responses the halophyte Schrenkiella parvula with its glycophytic relative species Arabidopsis thaliana stress and performed transcriptomic analysis S. roots identify possible gene regulatory networks underlying physiological responses. do not...
Soil salinity presents a dual challenge for plants, involving both osmotic and ionic stress. In response, plants deploy distinct yet interconnected mechanisms to cope with these facets of this investigation, we observed substantial overlap in the salt (NaCl)-induced transcriptional responses Arabidopsis roots those triggered by stress or plant hormone abscisic acid (ABA), as anticipated. Notably, specific cluster genes responded uniquely sodium (Na + ) ions are not regulated known monovalent...
Soil salinity is a major contributor to crop yield losses. To improve our understanding of root responses salinity, we developed and exploited real-time salt-induced tilting assay. This assay follows growth upon both gravitropic salt challenges, revealing that bending modulated by Na+ ions, but not osmotic stress. Next, measured this salt-specific response in 345 natural Arabidopsis (Arabidopsis thaliana) accessions discovered genetic locus, encoding the cell wall-modifying enzyme EXTENSIN...
Abstract Salinity stress constrains lateral root (LR) growth and severely affects plant growth. Auxin signaling regulates LR formation, but the molecular mechanism by which salinity auxin whether salt induces other pathways that regulate development remains unknown. In Arabidopsis thaliana, auxin-regulated transcription factor LATERAL ORGAN BOUNDARY DOMAIN 16 (LBD16) is an essential player in under control conditions. Here, we show high-salt conditions, alternative pathway LBD16 expression....
Abstract Soil salinity is a major contributor to crop yield losses. To improve our understanding of root responses salinity, we developed and exploit here real-time salt-induced tilting assay (SITA). This method follows growth upon both gravitropic salt challenges, revealing that bending modulated by but not osmotic stress. Next, this salt-specific response was measured in 345 natural Arabidopsis accessions discovered genetic locus, encoding for the cell-wall modifying enzyme EXTENSIN...
Abstract Soil salinity is an increasing worldwide problem for agriculture, affecting plant growth and yield. To understand the molecular mechanisms activated in response to salt plants, we investigated Catharanthus roseus Receptor like Kinase 1 Like (CrRLK1L) family, which contains well described sensors previously shown be involved maintaining sensing structural integrity of cell walls. We found that herk1the1-4 double mutants, lacking function Arabidopsis thaliana HERKULES1 combined with a...
Tip-growth is a mode of polarized cell expansion where incorporation new membrane and wall stably restricted to single, small domain the surface resulting in formation tubular projection that extends away from body cell. The organization microtubule cytoskeleton conserved among tip-growing cells land plants: bundles microtubules run longitudinally along non-growing shank network fine grow into apical dome growth occurs. Together, these networks control stable positioning site at surface....
Abstract Salinity stress constrains lateral root (LR) growth and severely impacts plant growth. Auxin signaling is indispensable for the regulation of LR formation. Nevertheless, molecular mechanism how salinity affects auxin whether salt would steer alternative pathway(s) to regulate development unknown. Here we show that auxin- regulated transcription factor LATERAL ORGAN BOUNDARY DOMAIN (LBD)16, known as an essential player under control conditions, by non-canonical pathway salinity. Salt...

Summary Warm temperatures have a dramatic effect on plant development. In shoots, stems elongate, and leaves are raised in developmental programme called thermomorphogenesis. This results enhanced leaf cooling capacity 1 . Thermomorphogenesis is tightly intertwined with light signalling pathways. The level of integration so high that it has been proposed shoot temperature sensing may evolved from the co-option an existing pathway during colonisation land by plants 2 Roots also undergo...
