Abstract Ammonium (NH4+) is both a necessary nutrient and an important signal in plants,
but can be toxic in excess. Ammonium sensing and regulatory mechanisms in plant cells …

The transient elevation of cytosolic free calcium concentration ([Ca2+] cyt) induced by cold
stress is a well‐established phenomenon; however, the underlying mechanism remains …

Plant cells have multiple plasma membrane (PM)-localized calcium ATPases (ACAs)
pumping calcium ions out of the cytosol. Although the involvement of some of these ACAs in …

Calcium ions (Ca 2+) play a crucial role in many key physiological processes; thus, the
maintenance of Ca 2+ homeostasis is of primary importance. Na+/Ca 2+ exchangers (NCXs) …

Abstract Calcium (Ca2+) mobilization is a central theme in various plant signal transduction
pathways. We demonstrate that Arabidopsis thaliana cyclic nucleotide-gated channel 2 …

Waterlogging is a major abiotic stress that limits the growth of plants. The crucial role of
Ca2+ as a second messenger in response to abiotic and biotic stimuli has been widely …

Cytosolic calcium signaling is critical for regulating downstream responses in plants
encountering unfavorable environmental conditions. In a genetic screen for Arabidopsis …

Abstract Calcium (Ca2+) is vital for plant growth, development, hormone response and
adaptation to environmental stresses, yet the mechanisms regulating plant cytosolic Ca2+ …

Little is known about the signalling processes involved in the response of roots to abiotic
stresses. The Arabidopsis root is a model system of root anatomy with a simple architecture …

ABSTRACT The Arabidopsis AINTEGUMENTA (ANT) gene, which encodes an APETALA2
(AP2)-like transcription factor, controls plant organ cell number and organ size throughout …
