Airborne lead: A vital factor influencing rice lead accumulation in China.

Traditionally, lead (Pb) in rice grains has been thought to be mostly derived from soil, and the contribution of aerosol Pb remains so far unknown. Based on a meta-analysis, we surprisingly found rice Pb content decreased proportionally with urban atmospheric Pb concentrations in major rice-growing provinces in China during 2001-2015, suggestive of the strong influence of long-range Pb transport on agricultural environment. With the combination of field survey, field experiment, as well as a predictive model, we confirmed high contribution of atmospheric exposure to rice grain Pb in China.

Role of hydrogen cyanamide (HC) in grape bud dormancy release: proteomic approach.

In the present study, we identified changes in protein expression patterns of grapevine buds when treated with hydrogen cyanamide (HC). HC induced a shift of more than 2-folds in the expression of 1250 proteins out of approximately 7000 detected proteins. The majority of the differentially expressed proteins (DEPs) were localized in the chloroplast (419) and cytoplasm (347).

Comparative Transcriptomic and Proteomic Analysis to Deeply Investigate the Role of Hydrogen Cyanamide in Grape Bud Dormancy.

Hydrogen cyanamide (HC) is an agrochemical compound that is frequently used to break bud dormancy in grapevines grown under mild winter conditions globally. The present study was carried out to provide an in-depth understanding of the molecular mechanism associated with HC releasing bud dormancy in grapevines. For this purpose, RNA-seq based transcriptomic and tandem mass tag (TMT)-based proteomic information was acquired and critically analyzed.

[Comparison of major bioactive components from leaves of Chrysanthemum morifolium].

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China.

[Effects of Cd stress on photosynthetic characteristics and nutrient uptake of cabbages with different Cd-tolerance].

With solution culture, this paper studied the plant growth, photosynthetic characteristics and nutrient uptake of two cabbage (Brassica oleracea L.) cultivars with different Cd-tolerance under treatments of 0, 20, 50 and 100 micromol Cd x L(-1). The results showed that the growth of Cd-sensitive cultivar Qiufeng was inhibited obviously even under low Cd concentration (20 micromol x L(-1)) stress.

Plant uptake and the leaching of metals during the hot EDDS-enhanced phytoextraction process.

Using pot experiments, the effect of the application of the biodegradable chelating agent S,S-ethylenediaminedisuccinic acid (EDDS) in hot solutions at 90 degrees C on the uptake of Cu, Pb, Zn, and Cd by corn (Zea mays L. cv. Nongda No.

[Research of polysaccharide from Dioscorea opposita Thunb].

Objective: To isolate a homogeneous polysaccharide RP from RDP (a crude polysaccharide from Dioscorea opposita Thunb.) , and study its preliminary composition and structure.

Methods: RP was obtained with water extraction, alcohol sedimentation, CTAB deprotein, cellulose column and SephadexG-100 column.
