Innovative research technique reveals C4 grasses older than previously thought A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence casts doubt on the widely-held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene epoch. The...

Photosynthesis is arguably the most impressive feat of nature, where plants harvest light energy and convert it into the building blocks of life at fantastically high efficiency. Indeed modern civilization became possible only with the cultivation of plants for food, shelter and clothing. While scientists have been able to discover details of the fascinating process by which plants store solar energy as chemical energy, how developing plants build and regulate their solar reactors is still...

A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests. Researchers have isolated and grown stem cells from a yew tree whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products....

TAU measures the effect of dew on desert plants When the scientific and spiritual worlds collide, they do so in the most surprising ways. Classical meteorological and plant science has, in the last century, insisted that dew negatively affects plant life, leading to rot and fungus. But in the Judeo-Christian tradition, dew is most welcomed as an important source of vegetative and plant life, celebrated in poetry and prayer. Now Prof. Pinhas Alpert of Tel Aviv University's Department of...

Nectar production in lima beans depends on light quality Flowering plants produce nectar to attract insect pollinators. Some plant species, such as Lima bean, also secrete nectar from so-called extrafloral nectaries to attract ants which in turn fend off herbivores. Scientists of the Max Planck Institute in Jena, Germany, have discovered that the production of extrafloral nectar is light dependent. They have shown that the plants are able not only to distinguish between day and night, but...

WINSTON-SALEM, N.C., Sept. 3 /PRNewswire-USNewswire/ -- As fat summer tomatoes dangle in profusion from vines in gardens and farms across the country, researchers at Wake Forest University are looking for a way to make future harvests hold up better against drought or lack of nutrients. But the tomatoes these researchers study, with names like Never Ripe and Green Ripe, are mutants that will never achieve that wonderful red that makes a perfect summer meal for many foodies. That's because...

A biosensor utilizing black platinum and carbon nanotubes developed at Purdue University will help give scientists a better understanding of how the plant hormone auxin regulates root growth and seedling establishment. Marshall Porterfield, an associate professor of agricultural and biological engineering and biomedical engineering, created a new sensor to detect the movement of auxin along a plant's root surface in real time without damaging the plants. The nanomaterials at the sensor's tip...

Charles Darwin described the Venus Flytrap as 'one of the most wonderful plants in the world.' It's also one of the fastest as many an unfortunate insect taking a stroll across a leaf has discovered. But what powers this speed? Dr Andrej Pavlovič of Comenius University, Slovakia, has been studying the plants with the help of some specialised equipment and a few unlucky insects. In the wild the Venus Flytrap grows in the bogs and savannahs of North and South...

Bittercress (Barbarea vulgaris), also commonly known as Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a European biennial herb. This plant displays a rosette of shiny, dark green leaves at the base and additional pinnately divided leaves on the stem. In the spring, yellow flowers originate in tightly packed terminal groups just above the foliage. Bittercress grows wildly as a weed in many parts of North America. The flowers can be in bloom May...

The Par Rubber Tree (Hevea brasiliensis), is a tree belonging to the family Euphorbiaceae. It is the most economically important member of the genus Hevea. It is of major economic importance because its sap-like extract (latex) can be collected and is the primary source of natural rubber. The Pará rubber tree initially grew only in the Amazon Rainforest. Now most rubber tree plantations are in southeast Asia and tropical Africa. Attempts to cultivate the tree in other areas in South...
