Kinesin Motor Proteins Are Essential for Male Gametophyte Development in Marsilea Vestita
Title of Dissertation: KINESIN MOTOR PROTEINS ARE ESSENTIAL FOR MALE GAMETOPHYTE DEVELOPMENT IN MARSILEA VESTITA Erika Jean Tomei, Doctor of Philosophy, 2016 Dissertation directed by: Professor Stephen M. Wolniak, Department of Cell Biology and Molecular Genetics The male gametophyte of the semi-aquatic fern, Marsilea vestita, produces multiciliated spermatozoids in a rapid developmental sequen...
متن کاملKinesin-2 family in vertebrate ciliogenesis.
The differentiation of cilia is mediated by kinesin-driven transport. As the function of kinesins in vertebrate ciliogenesis is poorly characterized, we decided to determine the role of kinesin-2 family motors--heterotrimeric kinesin-II and the homodimeric Kif17 kinesin--in zebrafish cilia. We report that kif17 is largely dispensable for ciliogenesis; kif17 homozygous mutant animals are viable ...
متن کاملSpermidine is a morphogenetic determinant for cell fate specification in the male gametophyte of the water fern Marsilea vestita.
Here, we show that the polyamine spermidine plays a key role as a morphogenetic determinant during spermatid development in the water fern Marsilea vestita. Spermidine levels rise first in sterile jacket cells and then increase dramatically in spermatogenous cells as the spermatids mature. RNA interference and drug treatments were employed to deplete spermidine in the gametophyte at different s...
متن کاملA Kinesin in Command of Primary Ciliogenesis
Primary cilia sense extracellular cues and in response transmit signals required for development and tissue homeostasis. A new study by Kobayashi et al. (2011) reports that the kinesin Kif24 controls the formation of primary cilia by restricting the nucleation of cilia at centrioles.
متن کاملThe fine structure of fertilization in the fern Marsilea vestita.
The ultrastructural details of fertilization in the fern Marsilea vestita, including gamete approach and fusion, the fate of the spermatozoid organelles and the development of a possible block to polyspermy are described. The spermatozoid approaches the egg through layers of mucilage that surround the megaspores. It moves down the neck of the archegonium into the cavity above the egg. In order ...
