In flowering plants, pollen tubes undergo tip growth to deliver two nonmotile sperm to the
ovule where they fuse with an egg and central cell to achieve double fertilization. This …

COVID-19 is an infectious disease caused by Coronavirus 2 (SARS-CoV-2) that may lead to
a severe acute respiratory syndrome. Such syndrome is thought to be related, at least in …

Pollen tube is the fastest-growing plant cell. Its polarized growth process consumes a
tremendous amount of energy, which involves coordinated energy fluxes between plastids …

Abstract Rho of Plants (ROPs) are GTPases that regulate polarity and patterned wall
deposition in plants. As these small, globular proteins have many interactors, it has been …

Shoot branching is a pivotal process during plant growth and development, and is
antagonistically orchestrated by auxin and sugars. In contrast to extensive investigations on …

Pollen germination is a process of polarity establishment, through which a single and unique
growth axis is established. Although most of the intracellular activities associated with pollen …

Legume symbiotic nitrogen fixation (SNF) is suppressed by inorganic nitrogen (N) in the soil.
High N inhibition of nitrogenase activity is associated with the deprivation of carbon …

Key message The pollen tube is being subjected to control by a complex network of
communication that regulates its shape and the misfunction of a single component causes …

Drought stress is one of the most important environmental stresses that severely limits the
growth and yield of Canola. The re-watering can compensate for the damage caused by …

Highlights•Cr RLK1L receptor-like kinases control many processes including pollen tube
growth.•CrRLK1Ls transmit information from the cell wall to the cell's interior.•RALF4/19 …
