Since the beginning, plants and animals have deployed various mechanisms to fight pathogens. Proteins have always played an important part in this armoury, and a broad variety of defensin proteins have become part of the immune system of plants, insects and other animals except mammals. Now scientists from Regensburg discovered that those proteins also play a role in the "sex life" during the fertilization process of plants. These findings will be published next week in the online, open...

New research confirms that early angiosperms were weedy, fast-growing Fossils and their surrounding matrix can provide insights into what our world looked like millions of years ago. Fossils of angiosperms, or flowering plants (which are the most common plants today), first appear in the fossil record about 140 million years ago. Based on the material in which these fossils are deposited, it is thought that early angiosperms must have been weedy, fast-growing shrubs and herbs found in highly...

Findings fuel ongoing debates over different approaches to dating the tree of life Flowering plants may be considerably older 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. Now, a paper to be published in the Proceedings of the National Academy of Sciences pushes back the age of angiosperms to 215 million years ago, some 25 to 75 million years earlier than either...

The origins of flowering plants from peas to oak trees are now in clearer focus thanks to the efforts of University of Florida researchers. A study appearing online this week in the Proceedings of the National Academy of Sciences unravels 100 million years of evolution through an extensive analysis of plant genomes. It targets one of the major moments in plant evolution, when the ancestors of most of the world's flowering plants split into two major groups. Together the two groups make up...

One hundred million years ago the earth looked very different from how it does today. Continents were joining and breaking apart, dinosaurs were roaming the earth, and flowering plants were becoming more widespread. The southern hemisphere supercontinent known as Gondwana formed around 180-200 mya during the breakup of Pangaea and then began to split apart about 167 mya. As scientists reconstruct the history of these land masses and life during this period, many questions arise. For example,...

Researchers work on part of Darwin's 'abominable mystery' Approximately 120-130 million years ago, one of the most significant events in the history of the Earth occurred: the first flowering plants, or angiosperms, arose. In the late 1800s, Darwin referred to their development as an "abominable mystery." To this day, scientists are still challenged by this "mystery" of how angiosperms originated, rapidly diversified, and rose to dominance. (See the January 2009 issue of the American Journal...

Flowering plants are all around us and are phenomenally successful"”but how did they get to be so successful and where did they come from? This question bothered Darwin and others and a paper published in the September issue of the Botanical Journal of the Linnean Society indicates that their ability to adapt anatomically may be the answer. Sherwin Carlquist, a research botanist at the Santa Barbara Botanic Garden and recipient of the Linnean Medal for Botany, has spent his career...

New algorithm explores future changes in plant populationsThe ability to envisage the future may be closer than you would think. A recent paper by Sean Hammond and Karl Niklas in the August 2009 issue of the American Journal of Botany (available here) presents an algorithm that may be used to predict the future dynamics of plant communities, an increasingly interesting area of study as significant environmental changes, such as global climate change and invasive species, are affecting current...

The appearance of many species of flowering plants on Earth, and especially their relatively rapid dissemination during the Cretaceous (approximately 100 million years ago) can be attributed to their capacity to transform the world to their own needs. In an article in Ecology Letters, Wageningen ecologists Frank Berendse and Marten Scheffer postulate that flowering plants changed the conditions during the Cretaceous period to suit themselves. The researchers have consequently provided an...

A U.S. study suggests a burst of flowering plants 90 million years ago led to the formation of forests and similar evolutionary bursts in animals. The University of Florida-led study was based on a DNA analysis of living flowering plants. Researchers determined the burst of speciation during a 5-million-year span was one of three major radiations of flowering plants, known as angiosperms. The study focused on diversification in the rosid clade, a group with a common ancestor that now accounts...

Waterlilies (Nymphaeaceae) belong to the Order Nymphaeales. They are tuberous plants that are rooted in soil in bodies of water, with leaves and flowers floating on the water surface. The leaves are round, with a radial notch in Nymphaea and Nuphar, but fully circular in Victoria. Modern genetic tests of the flowering plants by the Angiosperm Phylogeny Group have shown that the water-lilies are among the most primitive of the flowering plants. The white water-lily is the national flower...
