Abstract: | Background Tropical trees undergo severe stress through seasonal drought and flooding, and the ability of these species to respond may
be a major factor in their survival in tropical ecosystems, particularly in relation to global climate change. Aquaporins
are involved in the regulation of water flow and have been shown to be involved in drought response; they may therefore play
a major adaptive role in these species. We describe genetic diversity in the PIP sub-family of the widespread gene family
of Aquaporins in five Neotropical tree species covering four botanical families. |
