Exogenously supplied glycine betaine in spinach and rapeseed leaf discs: compatibility or non-compatibility?

Evaluation of Seed Yield Stability and Compatibility in Some Winter Rapeseed Genotypes

Extended Abstract Introduction and Objective: Brassica napus (L.) one of the most important oilseeds in temprate climates. In the most breeding programs, especially when comparing several genotypes in different environments, due to the interaction of genotype×environment, genotypes show different performances in different environments. Therefore, to accurately estimate grain yield, multi-envir...

Photorespiratory glycine metabolism in corn leaf discs.

The total glycine pool in Zea mays L. Mo17xB73 leaf discs was measured after steady state photosynthesis in 50%, 21% and 1% O(2). The glycine pool was a function of O(2) concentration; it was largest in 50% O(2) and smallest in 1% O(2). Incubation of discs with methyl hydroxybutynoic acid in 21% O(2) in the light caused an accumulation of carbon in glycolate. This accumulation was O(2) sensitiv...

Agile Methods and CMMI: Compatibility or Conflict?

During the last years, agile methods like eXtreme Programming have become increasingly popular. Parallel to this, more and more organizations rely on process maturity models to assess and improve their own processes or those of suppliers, since it has been getting clear that most project failures can be imputed to inconsistent, undisciplined processes. Many organizations demand CMMI compliance ...

Stimulus-Response Compatibility Is Information-Action Compatibility

Betaine accumulation and betaine-aldehyde dehydrogenase in spinach leaves.

Spinach leaf discs accumulated betaine when exposed to a mannitol solution of -20 bars. The accumulation was 12 micromoles per gram original fresh weight in a 24-hour period.Betaine-aldehyde dehydrogenase (EC 1.2.1.8) was assayed in various subcellular fractions prepared from spinach leaves, and it was found only in the soluble fraction. This cytosolic enzyme was purified 175-fold, and its prop...
