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 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 کاملCell Wall Loosening in the Fungus, Phycomyces blakesleeanus
A considerable amount of research has been conducted to determine how cell walls are loosened to produce irreversible wall deformation and expansive growth in plant and algal cells. The same cannot be said about fungal cells. Almost nothing is known about how fungal cells loosen their walls to produce irreversible wall deformation and expansive growth. In this study, anoxia is used to chemicall...
متن کاملEnhancement of wall loosening and elongation by Acid solutions.
The ability of low pH and CO(2) to induce rapid cell elongation and wall loosening in the Avena coleoptile has been examined with the use of a continuous growth-recording technique and an Instron extensometer, respectively. In particular, the properties of the response to hydrogen ions have been examined in detail and have been compared with the responses initiated by CO(2) and auxin. The optim...
