Cell-to-cell signaling is essential for many processes in plant growth and development,
including coordination of cellular responses to developmental and environmental cues …

Phytosulfokines (PSKs) are a class of disulfated pentapeptides and are regarded as plant
peptide hormones. PSK-α,-γ,-δ, and-ϵ are four bioactive PSKs that are reported to have …

Handbook of Biologically Active Peptides, Second Edition, is the definitive, indispensable
reference for peptide researchers, biochemists, cell and molecular biologists …

Despite much effort, a robust protocol for in vitro germination of Arabidopsis thaliana pollen
has been elusive. Here we show that controlled temperatures, a largely disregarded factor in …

▪ Abstract In flowering plants, pollen grains germinate to form pollen tubes that transport
male gametes (sperm cells) to the egg cell in the embryo sac during sexual reproduction …

Phytosulfokine (PSK) belongs to the group of plant peptide growth factors. It is a disulfated
pentapeptide encoded by precursor genes that are ubiquitously present in higher plants …

In recent years, numerous biochemical and genetic studies have demonstrated that peptide
signaling plays a greater than anticipated role in various aspects of plant growth and …

The tyrosine‐sulfated peptides PSK α and PSY 1 bind to specific leucine‐rich repeat surface
receptor kinases and control cell proliferation in plants. In a reverse genetic screen, we …

Siphonogamy, the delivery of nonmotile sperm to the egg via a pollen tube, was a key
innovation that allowed flowering plants (angiosperms) to carry out sexual reproduction on …

Increasing drought stress poses a severe threat to agricultural productivity. Plants, however,
have evolved numerous mechanisms to cope with such environmental stress. Here we …
