The nucellar beak is a proboscis-like outgrowth of the nucellus at the micropylar end, being the obliged path for the pollen tube entering the ovule. Among the few angiosperm families with nucellar beak, Cucurbitaceae is ...

Ripe pollen has different soluble and insoluble carbohydrates in variable amounts. Pollen germination and pollen tube growth were studied in a tomato cultivar (Solanum lycopersicum L. cv. Platense) with atypical pollen ...

Pollen tubes elongate by tip growth toward the ovule to deliver the sperm cells during fertilization. Since pollen tubes from several species can be grown in vitro maintaining their polarity, pollen tube growth is a ...

In flowering plants, the process of pollen germination and tube growth is required for successful fertilization. A pollen receptor kinase from tomato (Solanum lycopersicum), LePRK2, has been implicated in signaling during ...

Fruits formed after different pollination regimes (flowers hand pollinated, unpollinated, and open pollinated) and the seeds obtained were characterized in the wild chilli pepper Capsicum flexuosum Sendtn. Pollen tube ...

In plants, calcium signals are involved in multiple physiologicalprocesses such as stomatal opening, stress responses, and polarized growth ofroot hairs and pollen tubes. These signals are given as repetitive oscillationsof ...

Proper cell wall assembly is crucial during pollen tube growth. Leucine-rich repeat extensins (LRXs) are extracellular glycoproteins which belong to the hydroxyproline-rich glycoprotein (HRGP) family. They contain a conserved ...
