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...

Researchers discover the protein that transports sucrose to the plant´s vascular pathways Plants must supply their various tissues with the carbohydrates they produce through photosynthesis in the leaves. However, they do not have a muscular pump like the human heart to help transport this vital fuel. Instead, they use pump proteins in their cell membranes for this purpose. Together with colleagues from the Carnegie Institution for Science in California, Alisdair Fernie from the Max...

Food prices are soaring at the same time as the Earth's population is nearing 9 billion. As a result the need for increased crop yields is extremely important. New research led by Carnegie's Wolf Frommer into the system by which sugars are moved throughout a plant -- from the leaves to the harvested portions and elsewhere -- could be crucial for addressing this problem. Their work is published Dec. 8 by Science Express. Just as it's necessary for the human body to move nutrients to all of...

Nonindigenous insects and pathogens, including many that cause serious damage, have established in forests in the United States with regularity over 15 decades Nonindigenous insects and pathogens continue to become established in US forests with regularity despite regulations intended to prevent this, according to a study published in the December 2010 issue of BioScience. The study, by a team led by Juliann E. Aukema of the National Center for Ecological Analysis and Synthesis in Santa...

Guide to pumpkin, melon and plant vascular system The genome of the cucumber has been sequenced by an international consortium lead by Chinese and U.S. institutions. The annotated genome is published online Nov. 1 by the journal Nature Genetics. The cucumber genome will give insight into the genetics of the whole cucurbit family, which includes pumpkins and squash, melon and watermelon, and be a platform for research in plant biology, said William Lucas, professor and chair of the Department...
