CORVALLIS, Ore., Jan. 3 (UPI) -- A plant preserved in 100 million-year-old amber has revealed the oldest evidence of sexual reproduction in a flowering plant, U.S. and European researchers say.

Scientists have discovered a sexual reproduction process in microalgae that helps them better understand algae and plant evolution. Their discovery could lead to new industrial applications for ...

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 ...

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 ...

American Journal of Botany, Vol. 96, No. 5 (May, 2009), pp. 904-911 (8 pages) According to life-history theory, reproductive investments involve costs in terms of growth, future fecundity, and/or ...

Biogeographic models predict that, because of increasingly unfavorable and stressful conditions, populations become less frequent, smaller, less dense, and less reproductive toward the range edges.

Plants must constantly integrate information on the availability of water and nutrients or about the presence of pathogens to produce fruits and seeds for reproduction, heavily used for human ...
