UNIVERSITY PARK, Pa. -- A plant cell wall's unique ability to expand without weakening or breaking--a quality required for plant growth--is due to the movement of its cellulose skeleton, according to ...

IN the cell wall of plant fibres the submicroscopic cellulose strands are orientated in parallel. With some bast fibres they are orientated parallel to the cell axis (fibre texture), and with wood ...

Stomatal guard cells are pairs of specialized epidermal cells that control water and CO₂ exchange between the plant and the environment. To fulfill the functions of stomatal opening and closure that ...

Small-interfering RNAs (siRNAs) from natural cis-antisense pairs derived from the 3'-coding region of the barley (Hordeum vulgare) CesA6 cellulose synthase gene substantially increase in abundance ...

Plant cell walls are complex structures composed mostly of lignocellulose—the most abundant organic material on Earth—which is a matrix of cross-linked polysaccharide networks, glycosylated proteins, ...

WEST LAFAYETTE, Ind. - Simple sugars apparently are the biological signals needed to maintain the steel-like strength of plant cell walls, according to Purdue University scientists. "This is a really ...

Researchers have uncovered the mechanics of how plant cell walls balance the strength and rigidity provided by cellulose with its ability to stretch and compress. This discovery helps explain how ...

A new method developed by Penn State biologists allows them to turn stripped-down plant cells into other types of cells, similar to the way stem cells differentiate into different cell types. Using ...

Ikoma, Japan – Plant movement has been long fascinated by many researchers. Legumes are a group of plants famous for exhibiting various leaf movements, including “nyctinastic movement”, in which the ...

Plant cell wall growth is typically described as a simple process, but researchers using a microscope that can resolve images on the nanoscale level have observed something more complex. Plant cell ...
