NADPH oxidases (NOXs), mostly known as respiratory burst oxidase homologs (RBOHs),
are the key producers of reactive oxygen species (ROS) in plants. A lot of literature has …

Plant reproduction requires long-distance growth of a pollen tube to fertilize the female
gametophyte. Prior reports suggested that mutations altering synthesis of flavonoids, plant …

Directional control of tip-growing cells is essential for proper tissue organization and cell-to-
cell communication in animals and plants,. In the sexual reproduction of flowering plants, the …

Plant RHO GTPases (RAC/ROPs) mediate multiple extracellular signals ranging from
hormone to stress and regulate diverse cellular processes important for polarized cell …

Pollen tubes elongate within the pistil to transport sperms to the female gametophytes for
fertilization. Pollen tubes grow at their tips through a rapid and polarized cell growth process …

Pollen tubes extend rapidly via tip growth. This process depends on a dynamic actin
cytoskeleton, which has been implicated in controlling organelle movements, cytoplasmic …

Cell polarization is intimately linked to plant development, growth, and responses to the
environment. Major advances have been made in our understanding of the signaling …

In plants, the small GTP-binding proteins called Rops work as signalling switches that
control growth, development and plant responses to various environmental stimuli,,. Rop …

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 …
