Arabidopsis LIM proteins PLIM2a and PLIM2b regulate actin configuration during pollen tube growth
Biologia Plantarum, 2013 The pollen tube grows rapidly, exclusively at its tip, to deliver its sperm for fertilization. The polarized tip growth of pollen tubes is dependent on the highly dynamic actin cytoskeleton. Plant LIM proteins (named after initials of containing proteins

WD40-domain protein GORI is an integrative scaffold that is required for pollen tube growth in rice
Plant Signaling & Behavior, 2023 The pollen tube plays a critical role in angiosperm plants by delivering sperm gametes for double fertilization. Although the molecular mechanisms underlying pollen tube germination and growth are crucial to crop plants, they are poorly understood. Here,

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 ...

Rice, 2018 Background Pollen tube formation and growth are crucial steps that lead to seed production. Despite the importance of pollen tube growth, the molecular mechanisms implicated in its spatial and temporal control are not fully known. In this study, we found

BMC Plant Biology, 2019 Background During sexual reproduction, pollen grains land on the stigma, rehydrate and produce pollen tubes that grow through the female transmitting-tract tissue allowing the delivery of the two sperm cells to the ovule and the production of healthy ...

Ovary Signals for Pollen Tube Guidance in Chalazogamous Mangifera indica L.
Frontiers in Plant Science, 2021 Most flowering plants show porogamy in which the pollen tubes reach the egg apparatus through the micropyle. However, several species show chalazogamy, an unusual pollen tube growth, in which the pollen tubes reach the embryo sac through the chalaza ...

Effects of temperature on pollen viability and in vivo pollen tube growth in Citrus sinensis
Journal of Applied Botany and Food Quality, 2022 Temperature is the major factor in global warming and strongly influences the success of plant sexual reproduction. Therefore, there isan urgent need to assess the vulnerability of species for breeding and planning effective actions.

Signaling and the Modulation of Pollen Tube Growth [PDF]
The Plant Cell, 1999 Pollination in flowering plants begins when pollen lands on a stigma. The process continues as the pollen germinates and grows through intercellular spaces in the pistil, and it culminates when the pollen reaches the ovary and fertilization occurs.

The effect of temperature on pollen germination and pollen tube growth of sour cherry cultivars [PDF]
Journal of Agricultural Sciences (Belgrade), 2014 The study was carried out to determine the effect of three different temperatures (5, 15 and 25°C) on in vitro pollen germination and pollen tube growth of five sour cherry cultivars: ‘Heimanns Konservenweichsel’, ‘Kelleriis 14’, ‘Oblačinska ...
