Dual mechanisms give rise to biphasic stomatal opening in onion
New Phytologist, EarlyView.Anisotropic guard cell wall stiffness enhances onion stomatal pore opening by increasing guard cell arc length. Summary Stomata are controllable micropores on the leaf surface that regulate gas exchange and water loss. Pore aperture adjustment is a mechanical process whereby changes in guard cell turgor drive changes in cell shape, resulting in ...

New Phytologist, EarlyView.In a mature Scots pine forest (Pfynwald, Switzerland), canopy vapor pressure deficit (VPD)a was reduced with a misting system (a) and combined with a throughfall‐exclusion roof that imposed soil drought (b). Under the roofs (c), trees at ambient VPD closed their stomata steeply as predawn water potential (ΨPD) fell, reaching closure around −1.2 MPa ...

New Phytologist, EarlyView.miR160 links salicylic acid, auxin, and redox signaling with the growth–defense trade‐off in the potato hypersensitive response to potato virus Y. Summary Hypersensitive response (HR) is an effector‐triggered immune response leading to pathogen restriction and local cell death.

Embryonal degreening and seed longevity require plastid LEA proteins
New Phytologist, EarlyView.Working model of how plastidial LEA proteins aid the remodelling of photosynthetic structures during degreening of Arabidopsis seed embryos. LEA42 and LEA48 support thylakoid proteostasis and membrane remodelling in embryonal cells during late seed maturation by maintaining a local physicochemical environment compatible with protein turnover and ...

Guard cell size and initial conductance influence stomatal closure kinetics
New Phytologist, EarlyView.Conceptual overview of the two hypotheses linking stomatal anatomy to closure kinetics. Summary In fluctuating environments, the kinetics of stomatal opening and closing influence the balance between carbon gain and water loss. Smaller guard cells may respond faster to fluctuating environmental conditions because of their greater surface area for ...

AgriculturePlant cuticles are crucial for protecting plants from various environmental stresses. Seed priming with abscisic acid (ABA) enhances crop stress tolerance, but its molecular mechanisms in cuticular wax and cutin biosynthesis remain unclear.

, 2014 In this work, the response of the halophytic shrub Prosopis strombulifera to lowering an osmotic potential (Ψo) to -1.0, -1.9, and -2.6 MPa generated by NaCl, Na2SO4, and the iso-osmotic combination of them was studied at 6, 12, and 24 h after reaching ...
