Toward in vitro fertilization in Brachiaria spp. [PDF]
, 2010 Brachiaria are forage grasses widely cultivated in tropical areas. In vitro pollination was applied to accessions of Brachiaria spp. by placing pollen of non-dehiscent anthers on a solid medium near isolated ovaries.

Arabidopsis class I formins control membrane-originated actin polymerization at pollen tube tips
PLoS Genetics, 2018 A population of dynamic apical actin filaments is required for rapid polarized pollen tube growth. However, the cellular mechanisms driving their assembly remain incompletely understood.

Advanced Science, EarlyView.γGC deficiency in ulcerative colitis drives macrophage ferroptosis‐mediated inflammation. Claw‐engaged microparticles armed with γGC (γGC‐MPs) enhance lesion targeting, promoting localized γGC release and tissue uptake. On the cover, Monkey King (Macrophages) was bound by the Immortal‐Binding Rope and subsequently sealed beneath the Five‐Fingered ...

Stimulation of Nicotiana tabacum pollen tube growth by γ-irradiation [PDF]
, 1989 Irradiation of pollen grains from Nicotiana tabacum with 60Co-γ-irradiation in the dose range of 1–6Gy stimulates growth of the pollen tube up to 50% above control level.

The Long Journey of Pollen Tube in the Pistil
International Journal of Molecular Sciences, 2018 In non-cleistogamous plants, the male gametophyte, the pollen grain is immotile and exploits various agents, such as pollinators, wind, and even water, to arrive to a receptive stigma. The complex process of pollination involves a tubular structure, i.e.,

Pollen biology and hormesis: Pollen germination and pollen tube elongation
Science of The Total Environment, 2021 This paper evaluated the occurrence of hormetic dose responses in pollen reported over the past eight decades. Hormetic doses responses were induced by a wide range of chemical and physical agents in 34 plant species for pollen germination and pollen tube growth/elongation.

Advanced Science, EarlyView.High‐resolution spatiotemporal transcriptomic data from male and female spinach inflorescences across four key stages first reveal the sex differentiation initiates at the four‐leaf stage and is governed by epigenetic regulation via the SpMSI1‐SpHDT2 complex.

Communications Biology, 2018 During plant reproduction, sperm cells are delivered to ovules through growing pollen tubes. This process involves tip-localized receptor kinases regulating integrity and/or guidance of pollen tubes, whose localizations must be strictly regulated ...

Regulation of pollen tube growth [PDF]
Acta Botanica Neerlandica, 1995 Most textbooks describe pollen and pollen tubes as the vectors carrying the male sperm cells in seed plants. The pollen tubes grow through the style to the ovule, where the sperm cells are delivered to the egg cells in the embryo sacs. Pollen tubes always grow in an alien environment: in evolutionary terms they derive from the haustorium through which ...
