Reef-building corals are the framework builders for coral reefs and a key player in the coral reef ecosystem. They are the animals that form the foundation of Virgin Islands coral reefs which provide protection from the open ocean, are an economic resource in terms of tourism and fisheries, are the source of chemical compounds of biomedical importance, and provide great natural beauty. Due to b...
متن کاملSpontaneous hybridization between maize and teosinte.
The closest wild relatives of maize, Zea mays ssp. mays are various Zea taxa known as "teosinte." Hybrids between maize and the teosinte taxon, Zea mays ssp. mexicana, often occur when the 2 are sympatric in Mexico. Measuring the spontaneous hybridization rate of the 2 taxa would shed light on the mechanisms contributing to the evolution and persistence of these hybrid swarms. We conducted a se...
متن کاملExpression patterns and mutant phenotype of teosinte branched1 correlate with growth suppression in maize and teosinte.
The evolution of domesticated maize from its wild ancestor teosinte is a dramatic example of the effect of human selection on agricultural crops. Maize has one dominant axis of growth, whereas teosinte is highly branched. The axillary branches in maize are short and feminized whereas the axillary branches of teosinte are long and end in a male inflorescence under normal growth conditions. Previ...
متن کاملPhylogenetic relationships among prokaryotic and eukaryotic catalases.
Seventy-four catalase protein sequences, including 29 bacterial, 8 fungal, 7 animal, and 30 plant sequences, were compiled, and 70 were used for phylogenetic reconstruction. The core of the resulting tree revealed unique, separate groups of plant and animal catalases, two groups of fungal catalases, and three groups of bacterial catalases. The only overlap of kingdoms occurred within one branch...
