A team led by biologists at The University of Texas at Arlington has published a study supporting the theory that species that reproduce asexually have more harmful genetic mutations than those ...

Asexual, or vegetative, reproduction in plants is controlled by environmental conditions, but the molecular signaling pathways that control this process are poorly understood. Recent research suggests ...

The mechanism by which liverwort (Marchantia polymorpha) asexually reproduces via the development of clonal progenies (gemmae) has been revealed by a cross-institutional research group. They ...

Plant reproduction is highly complex and variable across the kingdom. The emergence of sexual reproduction has contributed to increase plant genetic diversity and enabled the colonisation of new ...

(Santa Barbara, Calif.) Why are most organisms sexual? The question of why most species reproduce sexually and others reproduce asexually has stymied biologists for years (particularly since asexual ...

When the female gametes in plants become fertilized, a signal from the sperm activates cell division, leading to the formation of new plant seeds. This activation can also be deliberately triggered ...

Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a head after an injury is a very different ...

THE Imperial Bureau of Horticulture and Plantation Crops, East Malling, has issued Technical Communication 13 on this subject by G. St. Clair Fielden and R. J. Garner. It deals with the vegetative ...
