A twelve-step program for evolving multicellularity and a division of labor
Autor: David L. Kirk
Publikováno v: BioEssays. 27:299-310
The volvocine algae provide an unrivalled opportunity to explore details of an evolutionary pathway leading from a unicellular ancestor to multicellular organisms with a division of labor between different cell types. Members of this monophyletic gro

Exploring germ-soma differentiation inVolvox
Autor: David L. Kirk, Marilyn M. Kirk
Publikováno v: Journal of Biosciences. 29:143-152
Professor MOP Iyengar, a preeminent expert on the green algae in the order Volvocales, and particularly those that are found on the Indian sub-continent (Iyengar and Desikachary 1981), first described this forma (subspecies) ofVolvox carteri (Iyengar

A Kinesin, InvA, Plays an Essential Role in Volvox Morphogenesis
Autor: Satoshi Ogihara, David L. Kirk, Ichiro Nishii
Publikováno v: Cell. 113(6):743-753
In Volvox carteri adults, reproductive cells called gonidia are enclosed within a spherical monolayer of biflagellate somatic cells. Embryos must "invert" (turn inside out) to achieve this configuration, however, because at the end of cleavage the go

Seeking the Ultimate and Proximate Causes of Volvox Multicellularity and Cellular Differentiation
Autor: David L. Kirk
Publikováno v: Integrative and Comparative Biology. 43:247-253
Volvox and its relatives provide an exceptional model for integrative studies of the evolution of multicellularity and cellular differentiation. The volvocine algae range in complexity from unicellular Chlamydomonas through several colonial genera wi

kangaroo, a Mobile Element From Volvox carteri, Is a Member of a Newly Recognized Third Class of Retrotransposons
Autor: Fay Yeh, Kristine A. Bouckaert, Leonard Duncan, David L. Kirk
Publikováno v: Genetics. 162:1617-1630
Retrotransposons play an important role in the evolution of genomic structure and function. Here we report on the characterization of a novel retrotransposon called kangaroo from the multicellular green alga, Volvox carteri. kangaroo elements are hig

Germ–Soma Differentiation in Volvox
Autor: David L. Kirk
Publikováno v: Developmental Biology. 238:213-223
Volvox carteri is a spherical green alga with a predominantly asexual mode of reproduction and a complete germ–soma division of labor. Its somatic cells are specialized for motility, incapable of dividing, and programmed to die when only a few days

Two enhancers and one silencer located in the introns of regA control somatic cell differentiation in Volvox carteri
Autor: Rüdiger Schmitt, Klaus Stark, David L. Kirk
Publikováno v: Genes & Development. 15:1449-1460
The regA gene plays a central role in germ-soma differentiation of Volvox carteri by suppressing all reproductive functions in somatic cells. Here we show that the minimal promoter of regA consists of only 42 bp immediately upstream of the transcript

The developmentally regulated ECM glycoprotein ISG plays an essential role in organizing the ECM and orienting the cells of Volvox
Autor: David L. Kirk, Armin Hallmann
Publikováno v: PUB-Publications at Bielefeld University
Volvox is one of the simplest multicellular organisms with only two cell types, yet it has a surprisingly complex extracellular matrix (ECM) containing many region-specific morphological components, making Volvox suitable as a model system for ECM in
