Comparative analysis of flavonoids, polyphenols and volatiles in roots, stems and leaves of five mangroves.

Mangrove plants contain a variety of secondary metabolites, including flavonoids, polyphenols, and volatiles, which are important for their survival and adaptation to the coastal environment, as well as for producing bioactive compounds. To reveal differences in these compounds among five mangrove species' leaf, root, and stem, the total contents of flavonoids and polyphenols, types and contents of volatiles were determined, analyzed and compared. The results showed that leaves contained the highest levels of flavonoids and phenolics.

Transcriptome and Metabolome Profiling Provide Insights into Flavonoid Synthesis in Linn.

is an important medicinal plant in mangrove forests, which is rich in secondary metabolites with various biological activities. In this study, we used transcriptomic analysis to obtain differentially expressed genes in the flavonoid metabolic pathway and metabolomic methods to detect changes in the types and content in the flavonoid metabolic synthesis pathway. The results showed that DEGs were identified in the mature roots vs.

Comparative transcriptomics and bioinformatics analysis of genes related to photosynthesis in .

The timber species is one of the most important in southern China. Therefore, it is essential to understand the photosynthetic pattern in eucalyptus leaves. In the present study, eighteen photosynthesis-related genes were analyzed using bioinformatics methods.

Screening cellulose synthesis related genes of EgrEXP and EgrHEX in Eucalyptus grandis.

Eucalyptus (including Eucalyptus grandis) is an excellent wood forest tree species that provides a large number of plant fiber raw materials for the paper and timber industries. Cellulose, an essential structural component in plant cell walls, is a renewable biomass resource that plays a very important role in nature. There is still a lack of research on the role of gene regulation in cellulose synthesis.

Transcriptome analyses reveals the dynamic nature of oil accumulation during seed development of Plukenetia volubilis L.

Sacha inchi (Plukenetia volubilis L.) is a shrub native to Amazon rainforests that's of commercial interest as its seeds contain 35-60% edible oil (dry weight). This oil is one of the healthiest vegetable oils due to its high polyunsaturated fatty acid content and favourable ratio of omega-6 to omega-3 fatty acids.

Novel species of Celoporthe from Eucalyptus and Syzygium trees in China and Indonesia.

Many species in the Cryphonectriaceae cause diseases of trees, including those in the genera Eucalyptus and Syzygium. During disease surveys on these trees in southern China, fruiting structures typical of fungi in the Cryphonectriaceae and associated with dying branches and stems were observed. Morphological comparisons suggested that these fungi were distinct from the well known Chrysoporthe deuterocubensis, also found on these trees in China.
