#Flowering plants May be Considerably Older Than Previously Thought A new analysis of the land plant family tree suggests that flowering plants may have lived much earlier than previously thought.

says a new analysis of the plant family tree. Previous studies suggest that flowering plants, or angiosperms, first arose 140 to 190 million years ago.

the researchers used a method that allows for variable rates of evolution across the plant family tree. oerates of molecular evolution in plants seem to be correlated with changes in life history,

and cereals and constitutes one of the most economically important plant families in the modern world. It is the first of the grass subfamily Pooideae to have sequenced a genome

Legumes an important plant family which includes lentils soybeans and peanuts have the ability to prosper in nitrogen-poor soil environments thanks to an ingenious adaptation:

This study demonstrates for the first time that host plants from different plant families and with different ecological strategies possess very different microbial communities on their leaves said lead author Steven W. Kembel a former postdoctoral researcher in the UO's Institute of Ecology

This stands in contrast to what's been suggested for several other large plant families where other investigators have noted correlations between high species diversity in a group and the presence of whole genome doublings or triplings.

Coffee lies in the plant family Rubiaceae which has about 13000 species and is the world's fourth largest;

Lupin a legume belonging to the same plant family as peanuts is showing up as a wheat replacement in an increasing number of gluten-free products.
