Reduced activity of Arabidopsis chromosome-cohesion regulator gene CTF7/ECO1 alters cytosine methylation status and retrotransposon expression
(2015-05-01)
Multicellular organisms such as higher plants require timely regulation of DNA replication and cell division to grow and develop. Recent work in Arabidopsis has shown that chromosome segregation during meiosis and mitosis ...
Arabidopsis Qc‑SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation
(2015-10-01)
Pollen tubes are rapidly growing specialized structures that elongate in a polar manner. They play a crucial role in the delivery of sperm cells through the stylar tissues of the flower and into the embryo sac, where the ...
The Opposing Actions of Arabidopsis CHROMOSOME TRANSMISSION FIDELITY7 and WINGS APART-LIKE1 and 2 Differ in Mitotic and Meiotic Cells
(2016-02-01)
Sister chromatid cohesion, which is mediated by the cohesin complex, is essential for the proper segregation of chromosomes during mitosis and meiosis. Stable binding of cohesin with chromosomes is regulated in part by the ...
Rise of the clones: apomixis in plant breeding
(Flowering plants: classification, characteristics and breeding, Chapter: 4, Publisher: Nova Publishers, Editors: J.J. Tellstone, pp.97-117, 2011)
In flowering plants the transfer of traits from one generation to the other involves fertilization of female gametophyte with sperm cells delivered by pollen tube, and the subsequent reassortment of traits (alleles) in the ...
Protocol for the preparation of Arabiopsis meiotic chromosome spreads and fluorescent in situ hybridization
(Bio-protocol 4(7), e1102, 2014, 2014-04-05)
This protocol is a more detailed version of previous protocols (Yang et al., 2011; Bolaños-Villegas et al., 2013) developed for the examination of meiotic chromosome spreads. Meiotic chromosome spreads are useful to determine ...
Arabidopsis CHROMOSOME TRANSMISSION FIDELITY 7 (AtCTF7/ECO1) is required for DNA repair, mitosis and meiosis
(The Plant Journal 75: 927–940, 2013-06-10)
The proper transmission of DNA in dividing cells is crucial for the survival of eukaryotic organisms. During cell division, faithful segregation of replicated chromosomes requires their tight attachment, known as sister ...
Pollen development: a play with many actors
(Current Topics in Plant Biology 11: 89-102. 2010, 2010-09-01)
Seeds are a major resource of food supply around the world and their production depends on successful double fertilization during plant sexual reproduction. In higher plants, fertilization of female gametophytes involves ...
