Regulation of Cambium Activity,iation of secondary vascular tissues. The cambium produces new cells that build the secondary xylem (the wood) and secondary phloem tissues which increase the thickness of stems and roots. The mechanisms that regulate cambial activity enable perennial trees to become the oldest organisms on earth by

Regulation of Juvenile-Adult Transition and Rejuvenations,, which occurs gradually during tree development, is regulated by hormonal signals and their gradients along the plant axis, with opposing mechanisms in conifers versus angiosperms. Gibberellin is a key controlling signal in juvenile-adult transition. GA promotes the transition from the juvenile to

Circular Vascular Tissues, Vessel Endings and Tracheids in Organ Junctions, that the induced vessel elements in these rings responded to the circular flux, rather than to a gradient or concentration of the auxin signal. The circular vessels are frequent in branch junctions, and they do not function in water transport and may interrupt water flow. Throughout the plant body,

Ray Differentiation: The Radial Pathways,and the phloem and vice versa. The chapter discusses the mechanism of how rays are induced and their dimensions are regulated. The rays are induced by a radial moving signal, which also induces the development of radial rays inside a vascular ray. The gaseous hormone ethylene, which is naturally syn

Environmental Adaptation of Vascular Tissues,afety mechanisms against drought and freezing. Conversely, forest trees and lianas, which characterize the tropics and rain forests, have low density vessels of very wide diameter at the base of their stems, which afford maximal efficiency of water conduction. To understand the mechanism that contro

Hormonal Control of Reaction Wood Formation,sition. In gymnosperm trees, the reaction wood is called . that develops in the lower side of curved stem. Compression wood is characterized by short, rounded tracheids that have thick walls with increased lignin content and increased microfibril angles that push the stem to upright position. In ang

Evidence shows that epigenetic modifications can be transmitted across generations. The environment control over gene expression and inheritance indi
