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 ...
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 ...
Reproduction in the animal kingdom has historically been sexual. Cloning the sheep Dolly in 1997 moved us closer to the possibility of duplicating other animals or humans asexually, but the practice ...
A scientist has moved a step closer to turning sexually-reproducing plants into asexual reproducers, a finding that could have profound implications for agriculture. Farmers throughout the world spend ...
Seeds are the end product of plant reproduction. Whether directly as food, or indirectly as animal feed, they provide around 80 percent of human calorie consumption. In the millennia since humans ...
Seed structure with a large central cell in the center (cell nucleus in yellow) surrounded by the tissue of the mother plant (purple). The mature central cell (left) is in a quiescent state until ...
Many clonal organisms occasionally outcross, but the long-term consequences of such infrequent events are often unknown. During five years, representing three to five plant generations, we followed 16 ...
International Journal of Plant Sciences, Vol. 169, No. 1, Special Issue Major Evolutionary Transitions in Flowering Plant Reproduction Edited by Spencer C. H. Barrett (January 2008), pp. 157-168 (12 ...
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 ...
