Mechanism of Action of CCS043 Utilizing Allelochemicals for Rhizosphere Colonization and Enhanced Infection Activity in .

is an important medicinal herb; but its long-term cultivation often leads to continuous cropping problems. The underlying cause can be attributed to the accumulation of and alterations in root exudates; which interact with soil-borne pathogens; particularly ; triggering disease outbreaks that severely affect its yield and quality. It is therefore crucial to elucidate the mechanisms by which root exudates induce CCS043 outbreaks.

Identification of a TuMV isolate (TuMV-ZR) from Pseudostellaria heterophylla and its development into a viral expression vector.

Pseudostellaria heterophylla (P. heterophylla) is a popular Chinese medicinal herb that is cultivated widely in China. Viral infection is commonly encountered during the production of P.

Over-immunity mediated abnormal deposition of lignin arrests the normal enlargement of the root tubers of Rehmannia glutinosa under consecutive monoculture stress.

The rapid accumulation of lignin in the cell wall is one of important immune defense mechanism in response to adversity stress in plants. In this study, we found that the enlargement of the root tubers of Rehmannia glutinosa (R. glutinosa) is arrested under consecutive monoculture stress, and this process is accompanied by abnormal accumulation of lignin.
