Intrusive growth of sclerenchyma fibers [PDF]

Russian Journal of Plant Physiology, 2010
Intrusive growth is a type of cell elongation when the rate of its longitudinal growth is higher than that of surrounding cells; therefore, these cells intrude between the neighboring cells penetrating the middle lamella. The review considers the classical example of intrusive growth, e.g., elongation of sclerenchyma fibers when the cells achieve the ...

Rays hamper intrusive growth of vessel elements

Trees, 2021
In some circumstances vessel elements, both broad and narrow, enlarge only symplastically in tangential direction. Rays play a special role in regulating intrusive enlargement of vessel elements. The aim of this study was to analyse relations occurring between vessel elements and surrounding cells, i.e.

Non-intrusive measurements of crater growth

Icarus, 2007
Abstract An experimental technique to measure crater growth is presented whereby a high speed video captures profiles of a crater forming after impact obtained using a vertical laser sheet centered on the impact point. Unlike previous so called “quarter-space experiments,” where projectiles were launched along a transparent Plexiglas sheet so that ...

Plant fiber intrusive growth characterized by NMR method

Russian Journal of Plant Physiology, 2006
Intrusively growing plant cells insert themselves between surrounding cells, thus increasing the number of membranes on the tissue cross-section. This parameter can be assessed by spin echo NMR method with a magnetic field pulse gradient. Diffusion echo decay was measured for stem regions of long-fiber flax (Linum usitatissimum L.) differing in the ...

Intrusive growth of flax phloem fibers is of intercalary type

Planta, 2005
Flax (Linum usitatissimum L.) phloem fibers elongate considerably during their development and intrude between existing cells. We questioned whether fiber elongation is caused by cell tip growth or intercalary growth. Cells with tip growth are characterized by having two specific zones of cytoplasm in the cell tip, one with vesicles and no large ...

The Form and Growth of Fingered Sheet Intrusions

Geological Society of America Bulletin, 1975
The form of several sheet intrusions in a sandstone-shale host rock is regular, but much more complex than the term “sheet intrusion” implies. The periphery of a sill emanating from the Shonkin Sag laccolith in Montana is composed of fingers of igneous rock with lengths of about 100 m, widths of 3 to 5 m, and thicknesses which vary from about 1.2 m ...

Intrusive tumor growth inspired optimization algorithm for data clustering

Neural Computing and Applications, 2015
Inspired by the invasive tumor growth mechanism, this paper proposes a new meta-heuristic algorithm. A population of tumor cells can be divided into three subpopulations as proliferative cells, quiescent cells, and dying cells according to the nutrient concentration they get.

A new mode of inner volcano growth: The “flower intrusive structure”

Earth and Planetary Science Letters, 2008
Abstract A multiple-sill laccolith nested within a centrally-dipping sheet swarm is a recently discovered sub-volcanic structure, resembling a “flower” in section-view, which we have found in some eroded volcanoes in Iceland, suggesting that this structure can have some general relevance in deforming rock successions in volcanic areas.
