Microscale Insight into Microbial Seed Banks
Microbial dormancy leads to the emergence of seed banks in environmental, engineered, and host-associated ecosystems. These seed banks act as reservoirs of diversity that allow microbes to persist under adverse conditions, including extreme limitation of resources. While microbial seed banks may be influenced by macroscale factors, such as the supply of resources, the importance of microscale e...

متن کاملThe utility of aged seeds in DNA banks
The long-term utility of DNA banks is predicated on the stability of DNA during storage. The quality and yield of DNA extracted from seeds from four garden species, which varied in age from 1 to 135 years old, was used to examine the early stages of DNA degradation. Seeds that were 70 years old yielded high molecular weight DNA, which permitted amplification of a 650bp segment of the internal t...
متن کاملTrematolobelia: Seed Dispersal; Anatomy of Fruit and Seeds
THE ENDEMIC HAWAIIAN GENUS Trematolobelia (Lobeliaceae, or Campanulaceae, subfamily Lobelioideae) was erected on the basis of its distinctive fruit. This fruit has a seed-dispersal mechanism unique in the family. Assertions have been made by some workers that holes in the fruit wall are the work of insects, and are not related to the dispersal mechanism. This contention has been adequately disp...
