Plant non-specific lipid-transfer proteins (nsLTPs) are small, basic proteins present in
abundance in higher plants. They are involved in key processes of plant cytology, such as …

▪ 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 …

In flowering plants, penetration of the pollen tube through stigma, style, and transmitting tract
is essential for delivery of sperm nuclei to the egg cells embedded deeply within female …

Plant lipid‐transfer proteins (LTPs) are abundant, small, lipid binding proteins that are
capable of exchanging lipids between membranes in vitro. Despite their name, a role in …

In flowering plants, sperm cells develop in the pollen cytoplasm and are transported through
floral tissues to an ovule by a pollen tube, a highly polarized cellular extension. After …

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 …

Plant cells are enclosed by a rigid cell wall that counteracts the internal osmotic pressure of
the vacuole and limits the rate and direction of cell enlargement. When developmental or …

In plant reproduction, pollination is an essential process that delivers the sperm through
specialized extracellular matrices (ECM) of the pistil to the ovule. Although specific …

ABSTRACT A plant's capability to cope with environmental challenges largely relies on
signal transmission through mitogen-activated protein kinase (MAPK) cascades. In …

Pollen tube guidance is a unique navigating system that is required for the successful sexual
reproduction of plants. As plant sperm cells are non-motile and egg cells are embedded …
