Root Hair Mutants of Barley
Almost sixty mutants with shortened or reduced root hairs or without root hairs at all have been isolated among 2000 M1 plant progenies (20.000 M2 seeds) of the spring barley cultivar “Lux” after sodium azide mutagenesis. One group of 25 mutants show fairly stable phenotype while 33 lines have unstable, indistinct or segregating phenotypes. The mutants were selected after 3 to 4 days growth in ...
متن کاملNitrate reductase-deficient mutants in barley : immunoelectrophoretic characterization.
Nitrate reductase-deficient barley (Hordeum vulgare L.) mutants were assayed for the presence of a functional molybdenum cofactor determined from the activity of the molybdoenzyme, xanthine dehydrogenase, and for nitrate reductase-associated activities. Rocket immunoelectrophoresis was used to detect nitrate reductase cross-reacting material in the mutants. The cross-reacting material levels of...
متن کاملAberrant cell expansion in the elongation mutants of barley.
The elongation (elo) mutants of barley (Hordeum vulgare cv 'Himalaya') are a class of dwarf plants with defects affecting cell expansion. The phenotypes of mutants in three of the elo loci (elo1, elo2 and elo3) are recessive to the wild-type allele, and the mutations at elo-4 and elo-5 are semi-dominant. Allelism tests showed that elo1, elo2 and elo3 were at separate loci, and mapping data indi...
متن کاملGenetic analysis of several root hair mutants of barley
Introduction Root hairs are specialized epidermal cells that play an important role in uptake of water and nutrients from rhizosphere. Each hair is a long, tubular, non-dividing cell characterized by tip growth, i.e. by deposition of new membrane and cell wall precursors at a cell-growing tip. Several root hair mutants have been isolated and genetically characterized in Arabidopsis thaliana (Pa...
متن کامل‘Overgrowth’ mutants in barley and wheat: new alleles and phenotypes of the ‘Green Revolution’ Della gene
A suppressor screen using dwarf mutants of barley (Hordeum vulgare L.) led to the isolation of 'overgrowth' derivatives, which retained the original dwarfing gene but grew at a faster rate because of a new mutation. The new mutations were in the Slender1 (Sln1) gene (11/13 cases), which encodes the DELLA protein central to gibberellin (GA) signalling, showed 100% genetic linkage to Sln1 (1/13),...
