Pollen phenotyping and performance in the rocoto chili (Capsicum pubescens Ruiz & Pav., Solanaceae)
(Taylor & Francis, 2015-01)
The rocoto chili (Capsicum pubescens) is a species native to the highlands of South America, which is cultivated for its fruits. The species is regarded as self-compatible; however, self-incompatible strains and even a ...
Pollen aquaporins: What are they there for?
(Taylor & Francis, 2016-09)
In order to provide more insight into the function of aquaporins during pollination, we characterized NIP4;1 and NIP4;2, 2 pollen-specific aquaporins of Arabidopsis thaliana. NIP4;1 and NIP4;2 displayed high amino acid ...
Nucellar beak structure and pollen tube growth in Cucurbitaceae
(Elsevier Gmbh, 2014-05)
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 ...
Pollen aperture heteromorphism in Centaurium pulchellum (Gentianaceae)
(Taylor & Francis As, 2007-03)
Pollen variations involving the number and position of the apertures are relatively frequent in certain members of Gentianaceae. In this paper the high incidence of pollen variation in Centaurium pulchellum (Sw.) Druce is ...
Arabidopsis Qc‑SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation
(2015-10-01)
Pollen tubes are rapidly growing specialized structures that elongate in a polar manner. They play a crucial role in the delivery of sperm cells through the stylar tissues of the flower and into the embryo sac, where the ...

Optimized method for growing In vitro Arabidopsis thaliana pollen tubes
(Humana Press, 2015)
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 ...
A Complex Journey: Cell Wall Remodeling, Interactions, and Integrity During Pollen Tube Growth
(Frontiers Media S.A., 2020-11-30)
In flowering plants, pollen tubes undergo a journey that starts in the stigma and ends in the ovule with the delivery of the sperm cells to achieve double fertilization. The pollen cell wall plays an essential role to ...
High temperatures during late floral bud stages decrease fertilization in strawberry (Fragaria ₓ ananassa): pollen-pistil interaction and anatomical evidences
High temperature (HT) effects on pistil tissues and female gametophyte have been scarcely investigated in crops species. During strawberry flowering, HT can induce fruit malformations due to poor pollen performance in ...
