Angiosperms

'angiosperms'

[media:Any [[member of the more than 250,000 Species of flowering plants (division magnoliophyta) having roots, stems, leaves, and well-developed conductive tissues (xylem and phloem). Angiosperms are often differentiated from gymnosperms by their production of seeds within a closed chamber (the ovary). Example: Aplle trees and all fruit trees. The ovary wall is actually the fruit. The magnoliophyta division is composed of two classes, the monocotyledons (liliopsida) and dicotyledons (magnoliopsida).

optimising yeast two hybrid testing conditions

... I'm looking at interactions between full length plant flowering proteins that are orthologous to proteins shown to interact in 3 other diverse angiosperms (monocots + dicots) - so I would be surprised if they didn't interact in my species, but at standard yeast growth conditions of 30'C (manufacturer's ...
