UCLA Biologists Uncover The Secrets Involved In Leaf Size, Shape
2013-10-31 14:36:02

Alan McStravick for redOrbit.com - Your Universe Online Trees, and more specifically, the leaves that adorn them, having predated human's foray into scientific learning, should harbor no mysteries at this point. However, nature continues to surprise us. Whether it is news of gold in eucalyptus leaves, as we learned last week with news out of Australia, or the simple yet profound truth of the math that governs internal leaf structure, human understanding continues to expand with the...

Is The Key To Immortality Held by Palm Trees

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...

The researchers decided to embark on this study in order to find out which mechanisms are used by plants when they extract water from very dry or somewhat inhospitable land. "In the case of mangrove swamps, for example, the plants are able to extract freshwater from a saltwater environment, despite the fact that the osmotic pressure should make quite the opposite happen", explains Professor Jos© Luis P©rez Díaz, who studies this type of relatively unknown...

A secret long held by plants has been revealed by Howard Hughes Medical Institute researchers. The new discovery, which builds on more than a decade of painstaking surveillance of cellular communication between different types of plant tissues, shows clearly for the first time how plants "decide" to grow. The research, conducted by Sigal Savaldi-Goldstein and Howard Hughes Medical Institute investigator Joanne Chory at The Salk Institute for Biological Studies, puts to rest a century-old...
