During a study on the genetic control of winterhardiness in winter wheat (Triticum aestivum L. group aestivum), a gene that affected vernalization was found on chromosome 3B in the winter wheat cultivar ;Wichita.' When chromosome 3B from Wichita was substituted into the winter wheat cultivar ;Cheyenne,' the resultant substitution line exhibited a spring growth habit. This is unusual since a cro...

Vernalization is classically defined as the induction of flowering process by exposure of the plants to a prolonged cold condition. Normally, it is considered as a precondition of flowering. Vicia faba, commonly known as faba bean, belongs to family Fabaceae. It is one of the plant species that has been cultivated in the earliest human settlements. In this study, an iTRAQ-LC-MS/MS-based quantit...

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 ...

BACKGROUND O-linked beta-N-acetylglucosamine (O-GlcNAc) modification of proteins mediates stress response and cellular motility in animal cells. The plant lectin concanavalin A can increase nuclear O-GlcNAc levels and decrease cytoplasmic O-GlcNAc levels in T lymphocytes. However, the functions of O-GlcNAc signaling in plants, as well as the relation between plant lectins and O-GlcNAc in respon...

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...

Adaptation to latitudinal patterns of environmental variation is predicted to result in clinal variation in leaf traits. Therefore, this study tested for geographic differentiation and plastic responses to vernalization in leaf angle and leaf morphology in Arabidopsis thaliana. Twenty-one European ecotypes were grown in a common growth chamber environment. Replicates of each ecotype were expose...

Vernalization, the promotion of flowering by a prolonged period of low temperature, results in repression of the floral repressor FLOWERING LOCUS C (FLC) and in early flowering. This repression bears the hallmark of an epigenetic event: the low expression state is maintained over many cell division cycles, but expression is derepressed in progeny. We show that the two stages of the response of ...

Aim. To determine the influence of alternative alleles Ppd-D1 gene and phenotypic differences in duration need for vernalization their interaction on earing time grain yield recombinant lines bread winter wheat. Methods. Growing plants field vegetation site, PCR with specific primers Ppd-B1c genes, phenological observations, artificial vernalization, statistical analysis. Results. 136 F7 from c...

Selection for heading date has been a decisive factor to increase areas cropped with oats in Brazil. Although important oat breeders, genomic regions controlling have not completely identified. The objective of this study was identify subtropical environments. A set 412 genotypes, developed from 1974 2015, assessed contrasting environments and genotyped using genotyping–by–sequencing (GBS). Phe...
