Growth-induced Water Potential Regulates Growth of Tissue-cultured Plantlets under Environmental Stresses.

The nature of the stresses induced during tissue growth

This work employs the constitutive principles of linear elasticity to examine the nature of growth-induced stresses in soft tissues. An analysis of the simpler case of isotropic growth gives insight into the effect of the spatial non-uniformity of the growth process on both the nature and distribution tissue stresses. Anisotropic growth is also considered, illustrating its role in relieving gro...

DIFFERENT GROWTH RESPONSES OF THE AXIAL AND COTYLEDONARY TISSUES OF SUNFLOWER SEEDS TO C H UNDER WATER AND SALT STRESSES

Effect of silicon application on wheat seedlings growth under water-deficit stress induced by polyethylene glycol

Silicon is known to ameliorate the deleterious effects of drought on plant growth. We evaluated growth of wheat (Triticum aestivum L. CV. Chamran) under Water-Deficit Stress Induced by Polyethylene Glycol as affected by Si application. In this article, the effects of Si (as potassium silicate) on some parameters related to growth, chlorophyll concentration relative water content (RWC), electrol...

Transglutaminase induced by epidermal growth factor negatively regulates the growth signal in primary cultured hepatocytes.

Transglutaminase (TGase) activity increased 2.5-fold at 6 h after treatment of rat hepatocytes with 17 nM epidermal growth factor (EGF). In the same manner, putrescine incorporation into the proteins of cells occurred in EGF-treated cells, but not in those pretreated with monodansylcadaverine (MDC), a TGase inhibitor, even in the presence of EGF. These results suggest that EGF-induced TGase was...

Growth of in vitro Oncidesa plantlets cultured under cold cathode fluorescent lamps with super-elevated CO2 enrichment

As interest in how to increase biomass production through biotechnological means gains traction, focus is turning towards the use of photoautotrophic micropropagation under elevated levels of carbon dioxide (CO2) to maximize plant growth and productivity. The effect of super-elevated CO2 with cold cathode fluorescent lamps (CCFLs) on the photoautotrophic growth of Oncidesa in vitro has been stu...
