Analysis of the chlorophyll catabolism pathway in leaves of an introgression senescence mutant of Lolium temulentum.
Pigments, proteins and enzyme activity related to chlorophyll catabolism were analysed in senescing leaves of wild-type (WT) Lolium temulentum and compared with those of an introgression line carrying a mutant gene from stay-green (SG) Festuca pratensis. During senescence of WT leaves chlorophylls a and b were continuously catabolised to colourless products and no other derivatives were observe...
متن کاملPoisonous Foodgrain: Wheat Mixed with Lolium Temulentum
In the March issue of this journal there appeared under 'Medical News' (p. 148; an abstract from an article by Brinton) an account of an epidemic at Aden caused by the seed of Lolium temulentum, a weed which grows in wheat fields. The wheat was brought from Abyssinia and milled locally by machinery. The consumption of the product made the inhabitants go down with symptoms of acute intoxication....
متن کاملRe-Programming Photosynthetic Cells of Perennial Ryegrass (Lolium perenne L) for Fructan Biosynthesis through Transgenic Expression of Fructan Biosynthetic Genes under the Control of Photosynthetic Promoters
High molecular weight fructans are the main class of water-soluble carbohydrate used for energy storage in many temperate grass species including perennial ryegrass (Lolium perenne L.). As well as being important readily mobilisable energy reserves for the plant, fructans are also involved in stress tolerance. Fructans are also readily digested by grazing ruminants and hence are a valuable sour...
متن کاملFructan biosynthesis in transgenic plants.
Data from plants transformed to accumulate fructan are assessed in the context of natural concentrations of reserve carbohydrates and natural fluxes of carbon in primary metabolism: Transgenic fructan accumulation is universally reported as an instantaneous endpoint concentration. In exceptional cases, concentrations of 60-160 mg g(-1) fresh mass were reported and compare favourably with natura...
متن کاملFructan synthesis is inhibited by phosphate in warm-grown, but not in cold-treated, excised barley leaves.
The inhibition of fructan accumulation by phosphate was investigated in warm-grown and cold-treated barley (Hordeum vulgare) plants. Detached leaves were incubated in water or phosphate for 24 h under lighting or in darkness. Fructosyltransferase, sucrose phosphate synthase (SPS) and cytosolic fructose-1,6-bisphosphatase (FBPase) activities were subsequently analysed, as well as the content of ...
