Ca2+ signals are a core regulator of plant cell physiology and cellular responses to the
environment. The channels, pumps, and carriers that underlie Ca2+ homeostasis provide …

Programmed cell death (PCD) is a process intended for the maintenance of cellular
homeostasis by eliminating old, damaged, or unwanted cells. In plants, PCD takes place …

Advances in plant cell molecular biology have considerably increased our understanding of
pollen-pistil barriers, particularly those operated by incompatibility mechanisms, and, at the …

Cold shock elicits an immediate rise in cytosolic free calcium concentration ([Ca2+] cyt) in
both chilling-resistant Arabidopsis and chilling-sensitive tobacco (Nicotiana …

Since water spontaneously ionizes, protons cannot be removed from the medium: their free
concentration in cells must be regulated through actively controlling H+-related transport …

Pollen tube growth attracts our attention as a model system for studying cell elongation in
plants. The process is fast, it is confined to the tip of the tube, and it is crucial for sexual …

Pollination in flowering plants begins when pollen lands on a stigma. The process continues
as the pollen germinates and grows through intercellular spaces in the pistil, and it …

Considerable advances have been made, both in the technologies available to study
changes in intracellular cytosolic free Ca2+ ([Ca2+] i), and in our understanding of Ca2+ …

The author offers an overview of pollen biology and biotechnology for students and
researchers in areas such as reproductive biology, biotechnology, aeropalynology, plant …

Significant advances in Ca2+ and calmodulin signalling in whole plants and individual cells
have been recently reported. Particular relevant contributions have been made to the study …
