The evolution of flowers is among the foremost topics in evolutionary science. There is a long-held hypothesis in botany that a flower is a telescoped shoot. It has been cherished by many botanists and supported by various ...
Radiocarbon dating of five large and potentially old sessile oaks from Aspromonte National Parks has revealed a long lifespan ranging from 934 ± 65 to 570 ± 45 years. For a long time, majestic oaks have been considered a ...
Balanophora have some of the smallest fruits among angiosperms, leading researchers to question how the seeds of these plants are dispersed. However, very little is currently known about their seed dispersal system. Associate ...
New research published today in Nature Ecology & Evolution by scientists from Australia and Mexico reveals the world's first complete angiosperm "time tree"—a reconstruction of the evolution of the Earth's flowering plants ...
Biologists from Lomonosov Moscow State University and HSE University have studied the patterns of flower development in yellow water-lily (Nuphar lutea). They found out that all the floral organs are arranged in cycles (whorls) ...
Multiple whole-genome duplications (WGDs) are found in most sequenced angiosperms. WGDs help plants to survive in extreme environments and contribute to phenotypic innovations. Duplicated genes following WGD often have different ...
Small RNAs are key regulators involved in plant growth and development. Two groups of small RNAs are abundant during development of pollen in the anthers—a critical process for reproductive success. A research collaboration ...
More than 110 million years ago, a lumbering 1,300-kilogram, armor-plated dinosaur ate its last meal, died, and was washed out to sea in what is now northern Alberta. This ancient beast then sank onto its thorny back, churning ...
The horn of Africa, located in the northeast of Africa, including Djibouti, Ethiopia, Eritrea and Somalia, is one of the global biodiversity hotspots recognized by United Nations Educational, Scientific and Cultural Organization ...
Like a snapshot, amber preserves bygone worlds. An international team of paleontologists from the University of Bonn has now described four new beetle species in fossilized tree resin from Myanmar, which belong to the Kateretidae ...
