Characterization of in L.

Unlabelled: L., which includes Chinese cabbage, turnip, and pak choi, has more complex flowering time regulation than does due to the presence of multiple paralogous flowering time genes. () is one of the key genes regulating the flowering time, and has four paralogs.

Tissue Culture in Ornamentals: Cultivation Factors, Propagation Techniques, and Its Application.

Ornamentals come in a variety of shapes, sizes, and colors to suit a wide range of climates, landscapes, and gardening needs. Compared to demand, a shortage of plant materials and diversity force the search for solutions for their constant acquisition and improvement to increase their commercial value, respectively. In vitro cultures are a suitable solution to meet expectations using callus culture, somatic embryogenesis, protoplast culture, and the organogenesis of protocorm-like bodies; many of these techniques are commercially practiced.

Characterization of Histone H3 Lysine 4 and 36 Tri-methylation in L.

Covalent modifications of histone proteins act as epigenetic regulators of gene expression. We report the distribution of two active histone marks (H3K4me3 and H3K36me3) in 14-day leaves in two lines of L. by chromatin immunoprecipitation sequencing.

Genome-wide analysis of long noncoding RNAs, 24-nt siRNAs, DNA methylation and H3K27me3 marks in Brassica rapa.

Long noncoding RNAs (lncRNAs) are RNA fragments that generally do not code for a protein but are involved in epigenetic gene regulation. In this study, lncRNAs of Brassica rapa were classified into long intergenic noncoding RNAs, natural antisense RNAs, and intronic noncoding RNAs and their expression analyzed in relation to genome-wide 24-nt small interfering RNAs (siRNAs), DNA methylation, and histone H3 lysine 27 trimethylation marks (H3K27me3). More than 65% of the lncRNAs analyzed consisted of one exon, and more than 55% overlapped with inverted repeat regions (IRRs).

Genome Triplication Leads to Transcriptional Divergence of Genes During Vernalization in the Genus .

The genus includes oil crops, vegetables, condiments, fodder crops, and ornamental plants. species underwent a whole genome triplication event after speciation between ancestral species of and closely related genera including . Diploid species such as and have three copies of genes orthologous to each gene, although deletion in one or two of the three homologs has occurred in some genes.

Genetics of Clubroot and Fusarium Wilt Disease Resistance in Brassica Vegetables: The Application of Marker Assisted Breeding for Disease Resistance.

The genus Brassica contains important vegetable crops, which serve as a source of oil seed, condiments, and forages. However, their production is hampered by various diseases such as clubroot and Fusarium wilt, especially in Brassica vegetables. Soil-borne diseases are difficult to manage by traditional methods.

In Heterosis Level Varies among Individuals in an F Hybrid Population.

Heterosis or hybrid vigour is a phenomenon in which hybrid progeny exhibit superior yield and biomass to parental lines and has been used to breed F hybrid cultivars in many crops. A similar level of heterosis in all F individuals is expected as they are genetically identical. However, we found variation in rosette size in individual F plants from a cross between C24 and Columbia-0 accessions of .

The histone modification H3 lysine 27 tri-methylation has conserved gene regulatory roles in the triplicated genome of Brassica rapa L.

Brassica rapa L. is an important vegetable and oilseed crop. We investigated the distribution of the histone mark tri-methylation of H3K27 (H3K27me3) in B.

The role of FRIGIDA and FLOWERING LOCUS C genes in flowering time of Brassica rapa leafy vegetables.

There is a wide variation of flowering time among lines of Brassica rapa L. Most B. rapa leafy (Chinese cabbage etc.

Long noncoding RNAs in Brassica rapa L. following vernalization.

Brassica rapa L. is an important agricultural crop that requires a period of prolonged cold for flowering. This process is known as vernalization.
