Quercetin alleviates seed germination and growth inhibition in Apocynum venetum and Apocynum pictum under mannitol-induced osmotic stress.

Quercetin is one of the main flavonoids in the human diet and mainly found in different plant tissues, including seeds, flowers, leaves, stems, and roots. However, its biological function in plant tissues, especially in seeds, is unknown. In this study, the seed germination and subsequent seedling growth of Apocynum pictum and A.

Dataset of full-length transcriptome assembly and annotation of using pacbio sequel II.

, which belongs to Apocynaceae, is widely distributed throughout salt-barren zones, desert steppes, and alluvial flats of the Mediterranean area and Northwestern China. has long been used in traditional Chinese medicine because of its anti-inflammation, anti-oxidative, anti-hypertensive, anti-cancer, and bactericidal effects. However, the absence of genetic information on  is an obstacle to understanding its stress resistance or medicinal function.

[Phyllosphere bacterial community structure of Osmanthus fragrans and Nerium indicum in different habitats.].

The diversity of phyllosphere bacteria is one of the hotspots in the research area of plant-microbial relationship. There are still a lot of controversies in the main factors influencing community structure of phyllosphere bacteria. In this study, the phyllosphere bacterial community structure of Osmanthus fragrans and Nerium indicum grown in three habitats was investigated based on high-throughput sequencing and the main driving factors were examined.

[Chloroplast genetic engineering: a new approach in plant biotechnology].

Chloroplast genetic engineering, offers several advantages over nuclear transformation, including high level of gene expression, increased biosafety, remedying some limitations associated with nuclear genetic transformation, such as gene silencing and the stability of transformed genes. It is now regarded as an attractive new transgenic technique and further development of biotechnology in agriculture. In this article we reviewed the characteristics, applications of chloroplast genetic engineering and its promising prospects were discussed.

Progress on molecular mechanism of T-DNA transport and integration.

Agrobacterium-mediated transformation is probably the most widely used method to introduce genes into plants. Great progress has been made in recent years in studies on the mechanism of Agrobacterium-mediated transformation. Agrobacterium genetically transforms plants by transferring a portion of the resident Ti-plasmid, the T-DNA, to the plant.
