Cell wall loosening by expansins.
In his 1881 book, The Power of Movement in Plants, Darwin described a now classic experiment in which he directed a tiny shaft of sunlight onto the tip of a grass seedling. The region below the coleoptile tip subsequently curved toward the light, leading to the notion of a transmissible growth stimulus emanating from the tip. Two generations later, follow-up work by the Dutch plant physiologist...
متن کاملExpansins: proteins that promote cell wall loosening in plants.
It was July 7, 1912, and Harry Houdini, ir the company of a bevy of dutiful report ers, was going to perform one of his greatest escapes, from a barge floating in the middle of the East River in New York. First he was shackled in leg irons two pairs of handcuffs, and elbow irons. Then he was crammed into a sturdy wooden crate, 40 inches x 22 inches x 24 inches, and the lid was nailed shut and r...
متن کاملXyloglucan endotransglucosylase and cell wall extensibility.
Transgenic tomato hypocotyls with altered levels of an XTH gene were used to study how XET activity could affect the hypocotyl growth and cell wall extensibility. Transgenic hypocotyls showed significant over-expression (line 13) or co-suppression (line 33) of the SlXTH1 in comparison with the wild type, with these results being correlated with the results on specific soluble XET activity, sugg...
متن کاملCatalysts of plant cell wall loosening
The growing cell wall in plants has conflicting requirements to be strong enough to withstand the high tensile forces generated by cell turgor pressure while selectively yielding to those forces to induce wall stress relaxation, leading to water uptake and polymer movements underlying cell wall expansion. In this article, I review emerging concepts of plant primary cell wall structure, the natu...
متن کاملAdaptation of roots to low water potentials by changes in cell wall extensibility and cell wall proteins.
It is common for the root/shoot ratio of plants to increase when water availability is limiting. This ratio increases because roots are less sensitive than shoots to growth inhibition by low water potentials. The physiological and molecular mechanisms that assist root growth under drought conditions are reviewed, with a focus on changes in cell walls. Maize seedlings adapt to low water potentia...
