chinmo-mutant spermatogonial stem cells cause mitotic drive by evicting non-mutant neighbors from the nicheC. Y. Tseng, M. Burel, M. Cammer, S. Harsh, M. S. Flaherty, S. Baumgartner and E. A. Bach, Developmental Cell, 2021.
Niches maintain a finite pool of stem cells via restricted space and short-range signals. Stem cells compete for limited niche resources, but the mechanisms regulating competition are poorly understood. Using the Drosophila testis model, we show that germline stem cells (GSCs) ... |

The supernumerary B chromosome of maize: drive and genomic conflictJ. A. Birchler and H. Yang, Open Biol, 11:210197. 2021.
The supernumerary B chromosome of maize is dispensable, containing no vital genes, and thus is variable in number and presence in lines of maize. In order to be maintained in populations, it has a drive mechanism consisting of nondisjunction at the pollen mitosis that produces ... |
