Polymorphic residues of a vacuolar Ca²⁺ sensor site in TPC1 channels differ between species of Brassicacea and Fabaceae and lead to distinct TPC1 gating behavior.

Recent findings about the possible intercellular signalling role of glutamate, GABA, and melatonin might help to establish hypotheses concerning the evolutionary factors that caused intercellular organisms to use specific molecules in intercellular signalling.

The SiPIP2;7 aquaporin is a functional CO₂ pore that can be used to improve CO₂ diffusion at the interface between the airspace and leaf mesophyll which limits C₄ photosynthesis.

Development of a real-time SnRK2 kinase FRET reporter reveals rapid SnRK2 activation by ABA, but not by Methyl-Jasmonate or elevated CO2, while directly demonstrating basal SnRK2 activity in guard cells.

Coupled physiology and gene expression, measured over a two-day time course, reveals specific time-of-day responses to the early stages of drought in Brassica rapa.

Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

Measurements of physiological and geometrical parameters of the sieve tube system in Ipomoea nil provide strong support for pressure driven mass flow.

Simple mathematical models can relate gene expression to climatic variables in field grown rice.

The calcium-dependent signaling pathway during ABA-dependent stomatal closure requires the calcium-independent pathway, and calcium signaling specificity is mediated by PP2C protein phosphatases.
