A tiny weed reveals an unexpected chemical connection between hormone pathways You might think you have nothing in common with mustard except hotdogs. Yet based on research in a plant from the mustard family, Salk scientists have discovered a possible explanation for how organisms, including humans, directly regulate chemical reactions that quickly adjust the growth of organs. These findings overturn conventional views of how different body parts coordinate their growth, shedding light on...

A New Look At How Plants Sense Gravity
2013-02-04 16:31:22

American Journal of Botany Gravity affects the ecology and evolution of every living organism. In plants, the general response to gravity is well known: their roots respond positively, growing down, into the soil, and their stems respond negatively, growing upward, to reach the sunlight. But how do plants sense gravity and how do they direct or signal their cells to grow in response to it? Although botanists understand a great deal about how this works, a recent article in the recent issue...

The Evolution Of Grass Photosynthesis
2012-12-26 05:22:06

Brett Smith for redOrbit.com - Your Universe Online In examining the differences in photosynthetic activity among certain types of grasses, researchers from Brown University found that some plants are positioned to take evolutionary advantage of certain situations. According to a report in the Proceedings of the National Academy of Sciences, Brown researcher Pascal-Antoine Christin spent two years analyzing the cellular anatomy of 157 living species of two different grass clades, BEP...

Is The Key To Immortality Held by Palm Trees
2012-12-19 14:01:56

American Journal of Botany Recent review reveals unique cellular structure and function that may contribute to their long life-span For centuries, humans have been exploring, researching, and, in some cases, discovering how to stave off life-threatening diseases, increase life spans, and obtain immortality. Biologists, doctors, spiritual gurus, and even explorers have pursued these quests–one of the most well-known examples being the legendary search by Ponce de León...

Future wood production quality tied to cambial function and regulation As large organisms, trees face some remarkable challenges, particularly regarding long-distance transport and communication. In addition to moving water and nutrients from their roots to their leaves, they must also integrate cell-to-cell communication over large areas. Furthermore, in order to function as a single, cohesive organism they must be able to effectively and efficiently send vital substances–such as...

Algae Held Captive And Their Genes Stolen In Crime Of Evolution
2012-11-28 15:38:41

University of Melbourne Microscopic animals held algae captive and stole their genes for energy production, thereby evolving into a new and more powerful species many millions of years ago reveals a new study published today in the journal Nature. The results reveal a 'missing link' in evolution because the tiny animal thieves (protozoa) couldn't completely hide all evidence of the captive algae, and have been effectively frozen in time and caught in the act by genetic sequencing....

Algae Draws Energy From Other Plants
2012-11-21 11:22:20

Bielefeld University Astonishing research finding by biologists at Bielefeld University published in the online journal Nature Communications Flowers need water and light to grow. Even children learn that plants use sunlight to gather energy from earth and water. Members of Professor Dr. Olaf Kruse´s biological research team at Bielefeld University have made a groundbreaking discovery that one plant has another way of doing this. They have confirmed for the first time that a plant,...

Key To Controlling Fruit Ripening Could Be In The Functions Of Chloroplasts
2012-11-01 14:51:47

University of Leicester Biologists may have unearthed the potential to manipulate the functions of chloroplasts, the parts of plant cells responsible for photosynthesis. Researchers in the University of Leicester's Department of Biology discovered that chloroplasts are affected by the ubiquitin proteasome system (UPS) — a process which causes the breakdown of unwanted proteins in cells, previously thought to only act on central parts of the cell. As a result, the researchers...

Using a computational model they designed to incorporate detailed information about plants´ interconnected metabolic processes, scientists at the U.S. Department of Energy´s Brookhaven National Laboratory have identified key pathways that appear to “favor” the production of either oils or proteins. The research, now published online in Plant Physiology, may point the way to new strategies to tip the balance and increase plant oil production. The study focused on the...

Recently, a mysterious seed fern, Lepidopteris baodensis sp. nov., dating to more than 251 million years ago (Ma), was discovered at the Baijiagou of Baode, Shanxi, China, from the Upper Permian Sunjiagou Formation. This discovery completely changed the understanding of the stratigraphic distribution of the genus Lepidopteris in China and promoted the taxonomic study of late Paleozoic plants. Since Schimper erected the genus Lepidopteris in 1869, its epidermal structure of subepidermal...

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...
