Grafting is a common method for clonal propagation of fruit trees. Moreover, it serves as a mean to deal with abiotic stress, adjust tree growth vigor, increase yield, and improve other fruit quality traits. Investigations of rootstock and scion graft relationships have originally focused on anatomical and cellular development, nutrient transport, and(More)
pH may act as a crucial signal in both animal and plant cells. It is very difficult to monitor pH signals and this has largely hindered progress in the investigation of pH signaling, particularly systematic pH signaling. Here, we report the development of a confocal technique to monitor leaf apoplastic pH in intact plants, which is particularly suitable for(More)
The study of global changes has focused on the reconstruction of paleovegetation and paleoclimate by n-alkanes and delta13C. 210Pb contents were measured for dating. The distribution characteristics of n-alkanes and delta13C were used to indicate the source of the organic matter in the sediments of Shijiu Lake. The relationship between modern(More)
Polybrominated dibenzo-p-dioxins (PBDDs) and hydroxylated polybrominated diphenyl ethers (OH-PBDEs) can be formed from bromophenols (BPs) by thermal degradation, biosynthesis or phototransformation. However, it is unknown whether PBDDs and OH-PBDEs can be formed during the chemical production processes that utilize BPs as raw materials. 2,4,6-tribromophenol(More)
