Why are there so many species of beetles and so few crocodiles?

There are more than 400,000 species of beetles and only two species of the tuatara, a reptile cousin of snakes and lizards that lives in New Zealand. Crocodiles and alligators, while nearly 250 million years old, have diversified ...

Gene function discovery: Guilt by association

Scientists have created a new computational model that can be used to predict gene function of uncharacterized plant genes with unprecedented speed and accuracy. The network, dubbed AraNet, has over 19,600 genes associated ...

Plant root hairs form outward due to shank hardening

A group of international researchers has discovered how plant root hair grows straight and long. Many studies of root hair growth have been performed, but the molecular mechanism for the suppression of growth on the sides ...

Living fossil genome unveiled

Published today in the open-access journal GigaScience, is an article that presents the genome sequence of Ginkgo biloba, the oldest extant tree species. The research was carried out by a team of scientists at BGI, Zheijiang ...

New research explores theories about aging and death in plants

(Phys.org) —According to Benjamin Franklin, "nothing can be said to be certain, except death and taxes." But what if Franklin had it wrong—at least about death? University of Georgia ecologist Richard P. Shefferson explored ...

Protecting crops from radiation-contaminated soil

Almost four years after the accident at the Fukushima Daiichi Nuclear Power Plant in Japan, farmland remains contaminated with higher-than-natural levels of radiocesium in some regions of Japan, with cesium-134 and cesium-137 ...

Manipulating genes with hidden TALENs

(PhysOrg.com) -- A better understanding of gene function in model plant and animal systems could be used to develop useful traits in livestock and crop plants, and might someday lead to developments in stem cell research ...

Hormone keys plant growth or stress tolerance, but not both

Plants that grow well tend to be sensitive to heat and drought, and plants that can handle those stresses often have stunted growth. A Purdue University plant scientist has found the switch that creates that antagonism, opening ...
