Unveiling the Molecular Mechanisms of Browning in Callus through Transcriptomic and Metabolomic Analysis.

is one of the camellia plants distributed in tropical regions, and its regeneration system and genetic transformation are affected by callus browning. However, the underlying mechanism of callus browning formation remains largely unknown. To investigate the metabolic basis and molecular mechanism of the callus browning of , histological staining, high-throughput metabolomics, and transcriptomic assays were performed on calli with different browning degrees (T1, T2, and T3).

Complete Chloroplast Genome Sequence of the Long Blooming Cultivar 'Xiari Qixin': Genome Features, Comparative and Phylogenetic Analysis.

The camellia flower is a famous woody plant with a long-cultivated history and high ornamental value. It is extensively planted and utilized around the world and owns a massive germplasm resource. 'Xiari Qixin' belongs to one of the typical cultivars in the four seasons camellia hybrids series.

Genome-Wide Identification of the Gene Family Involved in Fruitlet Abscission in L.

Fruitlet abscission frequently occurs in L. and causes considerable production loss. However, the inducement mechanism of fruitlet abscission remains mysterious.

Complete chloroplast genome of a cultivated oil camellia species, .

Hu et T. C. Huang, belonging to the Theaceae family, is an excellent landscape tree species with high ornamental value.

The complete chloroplast genome of , an edible oil Camellia.

is a new species of the genus discovered in Nanning, Guangxi, China, in 2012. It can be used as an excellent woody oil crop. There is little related research on this species in China and abroad, and its genome information is still lacking.

Iron Deficiency Leads to Chlorosis Through Impacting Chlorophyll Synthesis and Nitrogen Metabolism in L.

Deficiency of certain elements can cause leaf chlorosis in L. trees, which causes considerable production loss. The linkage between nutrient deficiency and chlorosis phenomenon and physiological defect in remains unclear.

The concrete evidence of flexistyly in : pollination biology of a wild ginger on Hainan Island, China.

Flexistyly in was first reported by Takano et al., while they provided no detailed study on pollination biology and breeding system. In this study, we tested this suspicion in one species of ().

Validation of the ITS2 region as a novel DNA barcode for identifying medicinal plant species.

Background: The plant working group of the Consortium for the Barcode of Life recommended the two-locus combination of rbcL+matK as the plant barcode, yet the combination was shown to successfully discriminate among 907 samples from 550 species at the species level with a probability of 72%. The group admits that the two-locus barcode is far from perfect due to the low identification rate, and the search is not over.

Methodology/principal Findings: Here, we compared seven candidate DNA barcodes (psbA-trnH, matK, rbcL, rpoC1, ycf5, ITS2, and ITS) from medicinal plant species.

Analysis of expressed sequence tags from the Huperzia serrata leaf for gene discovery in the areas of secondary metabolite biosynthesis and development regulation.

Huperzia serrata produces various types of lycopodium alkaloids, especially the huperzine A (HupA) that is a promising drug candidate for Alzheimer's disease. Despite the medicinal importance of H. serrata, little genomic or transcriptomic data are available from the public databases.
