2011-05-07South China Botanical Garden Finds Obligate Pollinators can Breakdown SporopolleninThe precise structure of sporopollenin is unknown. This chemical inertness accounts for the preservation of pollen grains for tens to hundreds of millions of years. No other insects visited the flowers of hot plants,and the moths’entire life cycle is adapted to their host plants’phenology and chemistry. The results showed that Phyllanthus coch... Sporopollenin is a complex polymer that is composed of fatty acids and phenolic compounds. The precise structure of sporopollenin is unknown. Sporopollenin is resistant to nonoxidative physical, chemical, and biological treatments and insoluble in both aqueous and organic solvents. This chemical inertness accounts for the preservation of pollen ...Read More -

2011-04-08South China Botanical Garden Finds a New Hyperaccumulator for Cd PhytoremediationPhytoremediation is a promising clean-up technology,which is to remedy soil heavy metal pollution with plants. Photeinocarpum showed no significant reduction with soil Cd treatment as high as 100 mg kg-1. In the transplanting-Cd concentration gradient experiment,plant shoot biomass was unaffected by soil Cd as high as 60 mg kg-1. Photeinocarpum ... Phytoremediation is a promising clean-up technology, which is to remedy soil heavy metal pollution with plants. The key to success of this technique is to find hyperaccumulators which can accumulate uniquely high quantities of heavy metals, for example, more than 1000 mg kg-1 for As, Pb, Cu, Ni, and Co, 10,000 mg kg-1 for Zn and Mn, and 100 mg k...Read More -
