Small RNAs (sRNAs) are key regulators involved in plant growth and development. Two groups of sRNAs are abundant during development of pollen in the anthers—a critical process for reproductive success. One of these pathways ...
Scientists have described a fossil plant species that suggests flowers bloomed in the Early Jurassic, more than 174 million years ago, according to new research in the open-access journal eLife.
About 140 years ago, Charles Darwin seemed to be bothered by evidence suggesting the sudden occurrence of numerous angiosperms in the mid-Cretaceous. Since Darwin's theory of evolution implies that all organisms should increase ...
A newly discovered fossil suggests that large, flowering trees grew in North America by the Turonian age, showing that these large trees were part of the forest canopies there nearly 15 million years earlier than previously ...
For angiosperms—or flowering plants—one of the most important decisions facing them each year is when to flower. It is no trivial undertaking. To flower, they must cease vegetative growth and commit to making those energetically ...
Diversity is strength, even among forests. In a paper published in Nature, researchers led by University of Utah biologist William Anderegg report that forests with trees that employ a high diversity of traits related to ...
Insect pollination played an important role in the evolution of angiosperms. Little is known, however, about ancient pollination insects and their niche diversity during the pre-angiosperm period due to the rarity of fossil ...
Flowering plants are well known for their special relationship to the insects and other animals that serve as their pollinators. But, before the rise of angiosperms, another group of unusual evergreen gymnosperms, known as ...
Plant physiologists from MSU have proved for the first time that dangerous reactive oxygen species that are often considered by-products of energy generation in cells are required by conifers to fertilize egg cells. Experiments ...
Some experts have long believed that a massive asteroid was a primary cause of dinosaurs' extinction some 65 million years ago, but new analysis from a University at Albany psychology professor suggests that the dinosaurs ...
