Acquisition of Thermotolerance in Soybean Seedlings : Synthesis and Accumulation of Heat Shock Proteins and their Cellular Localization.
When soybean Glycine max var Wayne seedlings are shifted from a normal growth temperature of 28 degrees C up to 40 degrees C (heat shock or HS), there is a dramatic change in protein synthesis. A new set of proteins known as heat shock proteins (HSPs) is produced and normal protein synthesis is greatly reduced. A brief 10-minute exposure to 45 degrees C followed by incubation at 28 degrees C al...
متن کاملRecovery of heat shock-triggered released apoplastic Ca2+ accompanied by pectin methylesterase activity is required for thermotolerance in soybean seedlings
Synthesis of heat shock proteins (HSPs) in response to heat shock (HS) is essential for thermotolerance. The effect of a Ca(2+) chelator, EGTA, was investigated before a lethal HS treatment in soybean (Glycine max) seedlings with acquired thermotolerance induced by preheating. Such seedlings became non-thermotolerant with EGTA treatment. The addition of Ca(2+), Sr(2+) or Ba(2+) to the EGTA-trea...
متن کاملEffects of Simulated Microgravity on Thermotolerance of Pea Seedlings
A coordinated plant response to simulated microgravity (clinorotation) and heat stress was analyzed. 5-d pea seedlings grown on a horizontal clinostat or in the stationary conditions were exposed to different heat treatments (mild, severe and severe after pretreatment). Temperature-dependent quantitative changes in the heat stress response were revealed in the clinorotated seedlings comparative...
متن کاملAnalysis of respiratory chain regulation in roots of soybean seedlings
Changes in the respiratory rate and the contribution of the cytochrome (Cyt) c oxidase and alternative oxidase (COX and AOX, respectively) were investigated in soybean (Glycine max L. cv Stevens) root seedlings using the 18O-discrimination method. In 4-d-old roots respiration proceeded almost entirely via COX, but by d 17 more than 50% of the flux occurred via AOX. During this period the capaci...
متن کاملBiosynthesis of malonate in roots of soybean seedlings.
Many plants accumulate malonate, but it was shown earlier that malonate does not accumulate as a deadend product of metabolism in soybean (Glycine max v. Hodgson tissues. The metabolism of malonate in the soybean plant at the whole tissue and enzymic level was followed, and the pathway of malonate biosynthesis in young soybean root tissue was shown to be via acetyl-coenzyme A carboxylase.
