Reconstructing the evolutionary history of detoxifying enzymes
Our body produces lots of enzymes that break down toxic substances. One class of such enzymes are the flavin-containing monooxygenases (FMOs), which are present in all tetrapods. Humans have five different FMO genes, of which ...

Gene duplication that appears to slow division of cells allows bowhead whales to live longer
A trio of researchers, one with the University of California-Berkeley, the other two with the University of Buffalo, has found a gene duplication in bowhead whales that may be at least partially responsible for their extremely ...
Plants can measure the intensity of salt stress
Unfavorable environmental conditions represent considerable stress for plants. A high level of salt content (sodium chloride, NaCl) in the soil is just such a stressor that has a negative impact on plants. Salinization is ...

For plant geneticists, some genes are double the trouble
When plant geneticists find a gene that improves crop yields, they want to try to insert that same change into other crops. But Cold Spring Harbor Laboratory Professor and HHMI Investigator Zachary Lippman cautions that ...

How grasses like wheat can grow in the cold
A new, large-scale analysis of the relationships among members of the largest subfamily of grasses, which includes wheat and barley, reveals gene-duplication events that contributed to the adaptation of the plants to cooler ...

A missing link in the MHC class divergence puzzle: Class II came first
Which came first, MHC class I or MHC class II? For decades, it has been debated which of these two similar classes came first in evolution. Now, Keiichiro Hashimoto and his group at Fujita Health University, Japan, in collaboration ...

DNA duplication linked to the origin and evolution of pine trees and their relatives
Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added genetic baggage. All those extra genes are then free ...

The molecular evolution of the aconitase superfamily
The aconitase superfamily currently contains four functional enzymes including the archetypical aconitase (referred to as "other aconitase enzymes"), and one hypothetical aconitase X (AcnX). The aconitase enzymes catalyze ...
