[physiological genetics of quantitative characters in arabidopsis thaliana (l.) heynh. : part 3. dauermodifications of pleiotropic effects of homoallelic genes].the genephysiological and developmental basis of "dauermodifications" (dm) have still not been explained. in particular definite evidence for dm in plastids is lacking up to now. moreover no attention has been paid to the connections with the problem of quantitative gene effects. for that reason mutants of the nuclear gene ch in arabidopsis thaliana (l.) heynh., quantitatively defective in chlorophyll b were tested during seven generations under continuous yellow radiation (λ < 550 nm) expecting ...197124430242
[physiological genetics of quantitative characters in arabidopsis thaliana (l.) heynh. : part 2: modification of primary and secondary genetic effects of single-gene chlorophyll-b mutants by long-wave irradiation].an analysis of the quantitative molecular effects of genes requires information on the norm of reaction ("reaktionsnorm") and on its variability in the genotype tested. 1) experiments were carried out in an automatically controlled growth chamber to determine the optimal conditions for the norm of reaction of the plants to be tested. genotypically determined variances between the characters studied and differences of means between test samples were most frequently significant when the growth con ...197124430106
[physiological genetics of quantitative characters in arabidopsis thaliana (l.) heynh. : part 1: segregation and biosynthesis of pigments in chlorophyll-b defect mutants].in biometric studies on the genetics of quantitative characters the problem of regulation of the activity of genes is rarely considered. mutants of arabidopsis thaliana (l.) heynh. (cruciferae), defective for chlorophyll b, permit a direct biochemical and physiological determination of their quantitative gene effects in the biosynthetic pathway of the plastid pigments. in agreement with other authors, the detectable genotypes are found to be based on multiple alleles (ch (+), ch (1) and ch (2)) ...197124430018

gene locus specificity of the glucose effect in the thiamine pathway of the angiosperm, arabidopsis.all mutants at 3 loci in arabidopsis thaliana (l.) heynh., a higher plant, that are associated with the synthesis or coupling of the thiazole moiety of thiamine are susceptible to reversible glucose inhibition. in contrast, several different alleles involved in the synthesis of the pyrimidine moiety of the vitamin are insensitive to glucose. glucose and maltose are equally effective inhibitors while fructose, lactose, ribose, and xylose are toxic. this toxicity is not released by added thiamine.196916657050

[disturbed thylakoid-formation in chloroplasts of a xantha-mutant of arabidopsis thaliana (l.) heynh].a monohybrid recessive xantha-mutant of arabidopsis thaliana was grown aseptically on mineral agar +2% sucrose up to maturity. the cotyledons and rosette leaves were non-green during all developmental stages, their yellow colour bleaching with age.palisade cells of various leaves of mutant plants were investigated light- and electron microscopically. all of the organelles of these cells, except the plastids, had a normal appearance. special attention was paid to the existence of "dense bodies", ...196624557822
[relations between chlorophyll content and chloroplast fine structure in a chlorina mutant of arabidopsis thaliana (l.) heynh].in a chlorina mutant (ch 3) of arabidopsis thaliana the total chlorophyll content was reduced to about 1/10 the amount of the green wild-type. at the same time the ratio of chlorophyll a/b was markedly increased. the electron microscopic analysis of the chloroplasts showed a considerable reduction in the membrane formation. especially an inhibition of the grana differentiation was apparent, leading in some stages to an entirely abnormal thylakoid stacking. depending on developmental as well as e ...196624557719
