PHOTOMORPHOGENESIS IN PLANT STEMS
Biological Reviews, 1964SummaryThe large morphological differences between plants grown in the dark and those exposed to light appear to result from an effect of light on accelerating the developmental process and causing it to proceed further. Light accelerates the early phase of expansion of stems but inhibits their final growth in length.At least two photochemical ...

American Midland Naturalist, 1971
Based on experiment, functional relationships are found that give, with considerable precision, the loading, the normal stress and the radius as a function of stem height. Using the functional relationship for the loading and for the normal stress, a theoretical expression for the radius distribution in the stem and for the volume of the stem is ...

The dynamic plant stem cell niches
Current Opinion in Plant Biology, 2007Stem cells exist in specific locations called niches, where extracellular signals maintain stem cell division and prevent differentiation. In plants, the best characterised niches are within the shoot and root meristems. Networks of regulatory genes and intercellular signals maintain meristem structure in spite of constant cell displacement by division.

Stem turnover strategy of multiple‐stemmed woody plants
Ecological Research, 2006Abstract We have investigated stem turnover strategy for Lindera umbellata , an understory shrub that sprouts from its rootstock under natural conditions to replace constituent stems, on the basis of the hypothesis that the multiple‐stemmed form of woody species is an ...

Stem Cell Signalling Networks in Plants
Plant Molecular Biology, 2006The essential nature of meristematic tissues is addressed with reference to conceptual frameworks that have been developed to explain the behaviour of animal stem cells. Comparisons are made between different types of plant meristems with the objective of highlighting common themes that might illuminate underlying mechanisms. A more in depth comparison
