The effect of temperature on pollen germination and pollen tube growth of pear cultivars [PDF]
Journal of Agricultural Sciences (Belgrade), 2016 The effect of three different temperatures (8, 16 and 24°C) on pollen germination and length of pollen tube in vitro was investigated in four pear cultivars (‘Butirra Precoce Morettini’, ‘Williams’, ‘Conference’ and ‘Abate Fetel’).

Cell Wall Composition, Biosynthesis and Remodeling during Pollen Tube Growth
Plants, 2013 The pollen tube is a fast tip-growing cell carrying the two sperm cells to the ovule allowing the double fertilization process and seed setting. To succeed in this process, the spatial and temporal controls of pollen tube growth within the female organ ...

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

Mechanics and hydraulics of pollen tube growth [PDF]
New Phytologist, 2021 SummaryAll kingdoms of life have evolved tip‐growing cells able to mine their environment or deliver cargo to remote targets. The basic cellular processes supporting these functions are understood in increasing detail, but the multiple interactions between them lead to complex responses that require quantitative models to be disentangled.

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 ...

Regulation of Pollen Tube Growth by Transglutaminase [PDF]
Plants, 2013 In pollen tubes, cytoskeleton proteins are involved in many aspects of pollen germination and growth, from the transport of sperm cells to the asymmetrical distribution of organelles to the deposition of cell wall material. These activities are based on the dynamics of the cytoskeleton.

Fast Pollen Tube Growth in Conospermum Species [PDF]
Annals of Botany, 2004 An unusual form of pollen tube growth was observed for several Conospermum species (family Proteaceae). The rate of pollen tube growth, the number of tubes to emerge and the ultrastructure of these tubes are given here.Pollen was germinated in vitro in different sucrose concentrations and in the presence of calcium channel blockers, and tube emergence ...

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 ...

Pollen-specific pectin methylesterase involved in pollen tube growth
Developmental Biology, 2006 Pollen tube elongation in the pistil is a crucial step in the sexual reproduction of plants. Because the wall of the pollen tube tip is composed of a single layer of pectin and, unlike most other plant cell walls, does not contain cellulose or callose, pectin methylesterases (PMEs) likely play a central role in the pollen tube growth and determination ...
