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 ...
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 ...
Characterization of calcium transporters during the pollen tube growth in Arabidopsis thaliana
(Tech Science Press, 2019)
In plants, calcium signals are involved in multiple physiologicalprocesses such as stomatal opening, stress responses, and polarized growth ofroot hairs and pollen tubes. These signals are given as repetitive oscillationsof ...
How many receptor-like kinases are required to operate a pollen tube
(Current Biology, 2017-10)
Successful fertilization depends on active molecular dialogues that the male gametophyte can establish with the pistil and the female gametophyte. Pollen grains and stigmas must recognize each other; pollen tubes need to ...
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 ...
Diverse ecological relations of male gametophyte populations in stylar environments
(Botanical Society of America, 2016-03)
PREMISE OF STUDY: Pollen on a stigma represents a local population of male gametophytes vying for access to female gametophytes in the associated ovary. As in most populations, density-independent and density-dependent ...
Self-compatibility of microgametophytes in Heliconia bihai (Heliconiaceae) from St. Lucia
(Caribbean Journal of Science, Vol. 44, No. 2, 145-149, 2008, 2014)
