Abstract:
... An ethylene biosynthesis-inducing xylanase (EIX) produced by the fungus Trichoderma viride elicited enhanced ethylene biosynthesis and leakage of potassium and other cellular components when applied to leaf disks of tobacco (Nicotiana tabacum L. cv Xanthi). Suspension-cultured cells of Xanthi tobacco responded to EIX by rapid efflux of potassium, uptake of calcium, alkalization of the medium, inhi ...

freezing; protein synthesis; acclimation; Secale cereale; ice; cold tolerance; leaves; plant proteins
Abstract:
... After cold acclimation, winter rye (Secale cereale L.) is able to withstand the formation of extracellular ice at freezing temperatures. We now show, for the first time, that cold-acclimated winter rye plants contain endogenously produced antifreeze protein. The protein was extracted from the apoplast of winter rye leaves, where ice forms during freezing. After partial purification, the protein wa ...

Abstract:
... Some pulvini of Samanea saman Mehr. labeled with radioactive phosphate show apparent remarkable elevations of the levels of phosphatidic acid and phosphatidylinositol 4,5-bisphosphate. The elevated levels, however, appear to be illusory and to result from rapid initial incorporation of label into these phospholipids relative to others. These results demonstrate the need for caution in interpreting ...

Abstract:
... Wheat (Triticum aestivum L. cv Etoile de Choisy) microsomes catalyzed the cytochrome P-450-dependent oxidation of the herbicide diclofop to three hydroxy-diclofop isomers. Hydroxylation was predominant at carbon 4, with migration of chlorine to carbon 5 (67%) and carbon 3 (25%). The 2,4-dichloro-5-hydroxy isomer was identified as a minor reaction product (8%). Substrate-specificity studies showed ...

Abstract:
... The development of a simple method for the isolation of purified carboxysomes from the cyanobacterium Synechococcus PCC7942 has made it possible to identify a specific and inducible, intracellular carbonic anhydrase (CA) activity that is strongly associated with carboxysomes. This was shown, in part, through enzyme recovery experiments that indicated that a clear majority of a CA activity that is ...

Abstract:
... Highly purified mitochondria isolated from 14-day-old pea (Pisum sativum L, cv Little Marvel) seedlings contain a homolog of the 70,000 molecular weight heat-shock protein. The amount of this heat-shock cognate (Hsc70) was not reduced by limited proteolysis of intact mitochondria or by preparation of mitoplasts, indicating that the protein is located within the matrix compartment. Pea mitochondria ...

Both CaM and CaM-binding proteins were found to be differentially distributed among organs, tissues, and protoplast types. CaM levels, on a per protein basis, were found to be the highest in leaf epidermis, containing 3-fold higher levels of CaM than in total leaf. Similarly, guard cell and epidermal ...

Abstract:
... We recently obtained evidence that the activity of spinach (Spinacia oleracea L.) leaf nitrate reductase (NR) responds rapidly and reversibly to light/dark transitions by a mechanism that is strongly correlated with protein phosphorylation. Phosphorylation of the NR protein appears to increase sensitivity to Mg2+ inhibition, without affecting activity in the absence of Mg2+. In the present study, ...

Stem water content was high in the fall (> 0.80) and decreased rapidly during 2 weeks of continuous freezing temperatures in late winter (< 0.60). Exudation of sap from stem segments subjected to freeze/thaw cycles was small (< 10 mL/kg) in the fall, but substantial exudation (45-50 mL/kg) ...
