Disturbances such as fire have the potential to remove genetic variation, but seed banks may counter this loss by restoring alleles through a reservoir effect. We used allozyme analysis to characterize genetic change in two populations of the perennial Hypericum cumulicola, an endemic of the fire-prone Florida scrub. We assessed genetic variation before and 1, 2, and 3 years after fire that killed nearly all aboveground plants. Populations increased in size following fire, with most seedlings likely recruited from a persistent seed bank. Four of five loci were variable. Most alleles were present in low frequencies, but our large sample …

Under natural conditions, Agrobacterium is a plant pathogen that infects plants by inserting genes into the plant's genome that are desirable to the bacterium itself. A tumor is then formed and the infected plant tissue makes molecules that the bacterium uses as food.

Kalanchoe pinnatum (syn. Bryophyllum pinnatum) is a succulent plant that is notable for developing small plantlets on the outer edges of its leaves, when its leaves are detached (Kulka 2006). These plantlets eventually drop off and root, which is a unique way for the plant to asexually reproduce. In most other plants, leaves exhibit determinate growth, meaning once they reach their maturity, they do not continue to grow.
