Shade tolerance as "Monstera deliciosa" and a number of other members of the family Araceae, such as members of the genus "Philodendron", initially grow "away" from light; this is a dramatic example of sciophilous growth, which helps them locate a tree trunk, which they then climb to regions of brighter light. The upper shoots and leaves of such a Philodendron grow as typical light-loving, "photophilic" plants once they break out into full sunshine. In forests where rainfall is plentiful and water is not the limiting factor to growth, shade tolerance is one of the most important factors characterizing tree species. However, different
1000 Plant Genomes Project based on the expression level (how many mRNA molecules it produces). This means that highly expressed genes get better coverage because there is more sequence to work from. The result, then, is that some important genes may not be reliably detected by the project if they are expressed at a low level yet still have important biochemical functions. Many plant species (especially agriculturally manipulated ones) are known to have undergone large genome-wide changes through duplication of the whole genome. The rice and the wheat genomes, for example, can have 4-6 copies of whole genomes (wheat) whereas animals typically only have
