Journal of Experimental Botany, 2015 MicroRNAs (miRNAs) are small noncoding regulatory RNAs that play key roles in the process of plant development. To date, extensive studies of miRNAs have been performed in a few model plants, but few efforts have focused on small RNAs (sRNAs) in conifers

Occurrence of crystals in vascular cambium
Protoplasma, 1984Crystals are of common occurrence in plant tissues and considered to be waste products resulting from active metabolism of plant cells. They mostly occur in ray and vertical parenchyma of wood and bark of angiosperm trees and often develop in tissues which soon cease to be functional.

Response of the vascular cambium to reorientation in patch grafts
Canadian Journal of Botany, 1976The vascular cambium was reoriented in square 5-mm panels of bark at 90° and 180° from the normal position in three varieties of Malus baccata and Malus sylvestris (ornamental crabapple), Cornus stolonifera, Sorbus aucuparia, and Thuja occidentalis, Douglasii pyramidalis. Panels grafted in the normal orientation served as controls.

The vascular cambium: structure and function
2010Perspective It is difficult to overemphasize the importance of the vascular cambium which produces secondary xylem and secondary phloem. In the following two chapters we shall discuss in detail the structure, functions, and the importance to the plant of these tissues which also have great significance for mankind.

THE ONTOGENY OF THE VASCULAR CAMBIUM IN THE STEM OF SEED PLANTS
Biological Reviews, 1965Summary1. A striking characteristic of the vascular cambium is its plasticity. It may arise in any position in any tissue except the epidermis. It may function in a variety of ways, giving rise to xylem or phloem alone, or to both tissues. If both xylem and phloem are formed from the same cambium, they may be derived from opposite faces of the meristem

The ontogeny of the vascular cambium inGinkgo biloba roots
The Botanical Magazine Tokyo, 1988Observation was made on early ontogeny of vascular cambium in the developing root ofGinkgo biloba L. After completion of root elongation, the vascular meristem gradually acquires cambial characteristics. Strips of the periclinal division of cells in transverse section are observed on the inner side of phloem when the primary xylem and phloem in the ...

Defect coarsening in a biological system: The vascular cambium of cottonwood trees
Physical Review E, 2003We present micrographic evidence for the annihilation of topological defect pairs and defect-mediated coarsening in the vascular cambium of cottonwood trees (Populus deltoides). We also show that a recently published mathematical model of cell orientation dynamics in the cambium reproduces many qualitative features of the defect coarsening process.

A Mathematical Model of Pattern Formation in the Vascular Cambium of Trees
Journal of Theoretical Biology, 2002The beautiful patterns apparent in wood grain have their origin in the alignment of fusiform initial cells in the vascular cambium of trees. We develop a mathematical model to describe the orientation of fusiform initial cells, and their interaction with the plant hormone indole-3-acetic acid (auxin).
