A new microbial metabolite, designated fistupyrone, was isolated from the culture broth of a plant-associated Streptomyces sp. TP-A0569. Fistupyrone inhibited the in vivo infection of the seedlings of Chinese cabbage by Alternaria brassicicola TP-F0423, the cause of Alternaria leaf spot, without any in vitro fungicidal activity.

Copper is among the major heavy metal contaminants in the environment with various anthropogenic and natural sources. Human health risk from heavy metal bioaccumulation in vegetables has been a subject of growing concern in recent years. To investigate Cu phytotoxic effects and bioaccumulation in the popular vegetable Chinese cabbage (Brassica pekinensis Rupr) as well as the implications for hu...

Mutants are ideal for studying physiological processes. The leaves of Chinese cabbage are a major place for photosynthesis, and the mutation of these leaves may directly affect the rate of plant growth and development, thus influencing the formation of its leafy head. We characterized a slow-growing mutant, which was designated as drm. The drm exhibited slow growth and development at the seedli...

Copper pollution in soils is widespread, and its accumulation in crop products could pose a risk on human health. In this paper, bioavailability of added copper (Cu) and critical Cu concentrations in a vegetable garden soil was evaluated for Chinese cabbage (Brassica chinensis L.), pakchoi (Brassica chinensis L.), and celery (Apiumg graveolens L. var. dulce DC) based on human dietary toxicity. ...

The live imaging techniques have been developed and applied to investigate for the first time the growth and development of Chinese cabbage for 18 days under microgravity conditions on board the Chinese SJ-8 recoverable satellite. These experiments offer insight into plant behaviors operating during plant development in space. Two automatic, preprogrammed CCD cameras were installed in the plant...

In order to raise awareness about environmental protection, people are paying more attention now-a-days in reusing wastepaper. As a result, most countries in the world have already made significant progress related to wastepaper recycling technology. This study was conducted to investigate the effects of slow-release fertilizer (SRF) on Chinese cabbage production. Wastepaper was deinked and the...
