Tomato pollen tube development and carbohydrate fluctuations in the autotrophic phase of growth
(Springer Heidelberg, 2012-11)
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 ...
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 ...
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 ...
The pollen receptor kinase LePRK2 mediates growth-promoting signals and positively regulates pollen germination and tube growth
(American Society of Plant Biologist, 2008-11)
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 ...
The effect of three plant bioregulators on pollen germination, pollen tube growth and fruit set in almond [Prunus dulcis (Mill.) D.A. Webb] cvs. Non Pareil and Carmel
(2015)
Background: In commercial almond [Prunus dulcis (Mill.) D.A. Webb] orchards in Chile, the percentage of fruit set is low and commonly reaches 5–30%. As almond trees bloom during a cool period and also suffer from ...
Cajal bodies are developmentally regulated during pollen development and pollen tube growth in Arabidopsis thaliana
(Elsevier, 2013-07)
In order to investigate whether the number and size of the CBs vary during the cell divisions and cellular differentiation that occur during pollen development, we used Arabidopsis thaliana pollen. Here, we show that ...
Assessment of in vitro pollen germination and pollen tube growth of Annona Cherimola mill
(2022)
Yield in cherimoya (Annona cherimola Mill.) is affected by various factors reducing fertilization and fruit production such as: the protogynous dichogamy of the flowers, deficient natural pollination, and low pollen quality. ...
Effects of pollen quality and quantity on pollen limitation in Crataegus monIncioogyna (Rosaceae) in NW Spain.
(Elsevier Gmbh, 2008-12)
Pollen limitation occurs when plants produce less fruits and/or seeds than they would with adequate pollen receipt. If the addition of cross-pollen to stigmas increases fruit/seed production, it is interpreted as an evidence ...
Arabidopsis pollen extensins LRX are required for cell wall integrity during pollen tube growth
(Elsevier Science, 2018-01-18)
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 ...
Fruit characteristics, seeds production and pollen tubes growth in the wild chilli pepper Capsicum flexuosum
(Elsevier Gmbh, 2011-05)
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 ...
