The characterization and geographical distribution of the genes responsible for vernalization requirement in Chinese bread wheat.
The frequency and distribution of the major vernalization requirement genes and their effects on growth habits were studied. Of the 551 bread wheat genotypes tested, seven allelic combinations of the three Vrn-1 genes were found to be responsible for the spring habit, three for the facultative habit and one for the winter habit. The three Vrn-1 genes behaved additively with the dominant allele ...
متن کاملNatural variation in Arabidopsis lyrata vernalization requirement conferred by a FRIGIDA indel polymorphism.
Species share homologous genes to a large extent, but it is not yet known to what degree the same loci have been targets for natural selection in different species. Natural variation in flowering time is determined to a large degree by 2 genes, FLOWERING LOCUS C and FRIGIDA, in Arabidopsis thaliana. Here, we examine whether FRIGIDA has a role in differences in flowering time between and within ...

fixity — the behavior of fossil organisms will be similar to the behavior of their extant descendants at the generic level — my wife and I re-constructed the type of Tertiary forest that existed in Hispaniola based on plants and animals in Dominican amber. We concluded that the amber forest in Hispaniola was similar to today’s tropical moist forest, but was much more diverse and contained a num...
متن کاملVernalization requirement duration in winter wheat is controlled by TaVRN-A1 at the protein level
Winter wheat requires a period of low temperatures to accelerate flowering (vernalization). This requirement could make winter wheat more vulnerable to elevated global temperature via insufficient vernalization. All known vernalization genes are cloned according to qualitative variation in vernalization requirement between spring and winter wheat, but the genes controlling quantitative variatio...
متن کاملAlteration of wheat vernalization requirement by alien chromosome-mediated transposition of MITE.
Under the changing climate, early flowering is advantageous to escape terminal heat and drought. Previously during evaluation of 14 chromosome introgression lines (ILs), we found three ILs that flowered a month earlier than their wheat background Chinese Spring (CS). This paper describes the cause of the early flowering in the ILs and provides insight into the evolution of spring wheat from the...
