The Dynamics of Cambial Stem Cell Activity

Annual Review of Plant Biology, 2019
Stem cell populations in meristematic tissues at distinct locations in the plant body provide the potency of continuous plant growth. Primary meristems, at the apices of the plant body, contribute mainly to the elongation of the main plant axes, whereas secondary meristems in lateral positions are responsible for the thickening of these axes. The stem

Forward Modeling Reveals Multidecadal Trends in Cambial Kinetics and Phenology at Treeline

Frontiers in Plant Science, 2021
Significant alterations of cambial activity might be expected due to climate warming, leading to growing season extension and higher growth rates especially in cold-limited forests. However, assessment of climate-change-driven trends in intra-annual wood

Overexpression of INCREASED CAMBIAL ACTIVITY, a putative methyltransferase, increases cambial activity and plant growth [PDF]

Journal of Integrative Plant Biology, 2016
ABSTRACTCambial activity is a prerequisite for secondary growth in plants; however, regulatory factors controlling the activity of the secondary meristem in radial growth remain elusive. Here, we identified INCREASED CAMBIAL ACTIVITY (ICA), a gene encoding a putative pectin methyltransferase, which could function as a modulator for the meristematic ...

Activation of Cambial Growth [PDF]

Nature, 1935
EVIDENCE was recently obtained by one of us1 indicating that the influence coming down from the leaves, which activates cambial growth, is a hormone. Also Laibach2 has caused decapitated epicotyls of Vicia Faba and various leaf-stalks to grow in thickness by placing on them the pollinia of orchids, which he has shown to exude large quantities of auxin,

Variation in Onset of Leaf Unfolding and Wood Formation in a Central African Tropical Tree Species

Frontiers in Forests and Global Change, 2021
A diversity of phenological strategies has been reported for tropical tree species. Defoliation and seasonal dormancy of cambial activity inform us on how trees cope with water stress during the dry season, or maximize the use of resources during the ...

Concomitant analysis of cambial abscisic acid and cambial growth activity in poplar [PDF]

Trees, 2013
Endogenous levels of cambial region abscisic acid (ABA) were quantified by immunoassay and assessed together with cambial growth activity in poplar (Populus nigra L. × P. maximowiczii Henry, clone Kamabuchi) over the course of a growing season. The level of cambial region ABA increased from spring to late-summer but decreased sharply in autumn. Cambial

Xylem plasticity in Pinus pinaster and Quercus ilex growing at sites with different water availability in the Mediterranean region: relations between Intra-Annual Density Fluctuations and environmental conditions. [PDF]

, 2020
Fluctuations in climatic conditions during the growing season are recorded in Mediterranean tree-rings and often result in intra-annual density fluctuations (IADFs).

Cambial Age Influences PCD Gene Expression during Xylem Development and Heartwood Formation

Plants, 2023
Heartwood formation is an important ontogenetic stage in Scots pine (Pinus sylvestris L.). The amount of heartwood determines the proportion of functionally active sapwood in the total trunk biomass as well as the quality of wood.

The effects of watering on cambial activity in the stems of evergreen hardwood (Samanea saman) during the pre-monsoon season in subtropical Bangladesh

Journal of Wood Science, 2022
Water stress has a significant impact on tree growth. However, the effects of watering on cambial activity and its influence on tree growth in subtropical climates is poorly understood.
