Transcriptome Sequencing and Screening of Anthocyanin-Related Genes in the Leaves of Acer truncatum Bunge.

Acer truncatum Bunge is generally used as an ornamental tree because of its autumn leaves, although the viewing period is short-approximately 7-15 days. Color improvement of ornamental trees has consistently been an important research topic because color partially determines the value of the commodity; however, a lack of genomic data have limited the progress of molecular breeding research in this area. The purposes of this study were to obtain a transcriptome database for A.

Transcriptome sequencing and flavonoid metabolism analysis in the leaves of three different cultivars of Acer truncatum.

Young and mature leaves of three Acer truncatum varieties with different leaf colors were examined. Transcriptome sequencing and flavonoid metabolism were used to analyze the differential gene expression associated with different leaf colors and growth stages and the relationships between gene expression and flavonoid and anthocyanin contents to improve ornamental value and develop flavonoid-rich A. truncatum.

Characterization of the complete chloroplast genome of 'Guanghui'.

The first complete chloroplast genome of Lindl.

Lindl. is an important medicinal plant, for which complete chloroplast genome (Accession: MN782301) was sequenced, assembled and annotated. The genome size is 161,668 bp and the overall GC content is 36.

Characterization and phylogenetic analysis of the complete chloroplast genome of 'Forest Pansy'.

'Forest Pansy' is a tree species with high ornamental value, which complete chloroplast (cp) genome was sequenced, assembled, and annotated. The genome size is 158,960 bp with a total GC content of 36.17%.

Construction of Pseudomolecules for the Chinese Chestnut () Genome.

The Chinese chestnut ( Bl.) is a woody nut crop with a high ecological value. Although many cultivars have been selected from natural seedlings, elite lines with comprehensive agronomic traits and characters remain rare.

[Effects of hydrogen sulfide on mitochondrial function in sweet cherry stigma and ovary under low temperature stress].

To investigate the effects of HS on mitochondrial functions under low temperature stress, we analyzed the effects of 0.05 mmol·L NaHS and 15 μmmol·L HT (hypotaurine and HS scavenger) on mitochondria antioxidant enzyme activities and mitochondrial permeability transition pore, mitochondrial membrane fluidity, mitochondrial membrane potential, Cyt c/a ratio and H-ATPase activity in sweet cherry stigma and ovary with sweet cherry variety Zaodaguo under -2 ℃ low temperature stress. The results showed that low temperature stress increased the concentrations of mitochondrial HO and MDA, enhanced the mitochondrial membrane permeability, but decreased the mitochondrial membrane fluidity, membrane potential, Cyt c/a and H-ATPase acti-vity.

Molecular Link between Leaf Coloration and Gene Expression of Flavonoid and Carotenoid Biosynthesis in Cultivar 'Huangjinya'.

'Huangjinya' is an excellent albino tea germplasm cultivated in China because of its bright color and high amino acid content. It is light sensitive, with yellow leaves under intense light while green leaves under weak light. As well, the flavonoid and carotenoid levels increased after moderate shading treatment.
