Between fifty and ten thousand years ago, most large mammals became extinct everywhere
except Africa. Slow-breeding animals also were hard hit, regardless of size. This unusual …

Recently nitric oxide (NO) has emerged as a key signalling molecule in plants. Here we
review the potential sources of endogenous NO, outline the biological processes likely to be …

Abscisic acid (ABA) is a sesquiterpene signaling molecule produced in all kingdoms of life.
To date, the best known functions of ABA are derived from its role as a major phytohormone …

The mode of abscisic acid (ABA) action, and its relations to drought adaptive responses in
particular, has been a captivating area of plant hormone research for much over a decade …

There are eight thermosensitive TRP (transient receptor potential) channels in mammals,
and there might be other TRP channels sensitive to temperature stimuli. Here, we …

Despite progress in the past decade, researchers struggle to evaluate the hypothesis that
environmental conditions compromise immunity and facilitate new disease outbreaks. In this …

Mass mortality events are increasing dramatically in all coastal marine environments.
Determining the underlying causes of mass mortality events has proven difficult in the past …

Background Abiotic stresses adversely affect plant growth and development. The hormone
abscisic acid (ABA) plays a central role in the response and adaptation to environmental …

Abscisic acid (ABA) is a phytohormone involved in fundamental physiological processes of
higher plants, such as response to abiotic stress (temperature, light, drought), regulation of …

Calcium controls a number of critical events, including motility, secretion, cell invasion and
egress by apicomplexan parasites. Compared to animal and plant cells, the molecular …
