The signalling pathways mediating defence responses induced in suspension cultures of ginseng, Panaxginseng C.A. Meyer, by the plant cell wall-derived elicitor oligogalacturonic acid (OGA) were *** induced the rapid generation and release of hydrogen peroxide, HO, potentially via an NADPHoxidase-like enzyme. In addition, OGA elicited the synthesis of jasmonic acid (JA) and the defence compoundsaponin, and expression of genes encoding squalene synthase (sqs;EC 2.***.1.2.) and squalene epoxidase (sqe;EC 1.***.99.7), key enzymes of saponin biosynthesis. HO and JA also induced saponin synthesis andtranscription of sqs and sqe. The synthesis of JA, but not that of HO, was inhibited by an inhibitor of JAbiosynthesis, whereas the accumulation of both HO and JA were inhibited by treatments that removed HOor inhibited its production. Moreover, HO stimulated JA synthesis, but JA treatment had no effect on HO

Terpenoids play important roles in plant-insect,plant-pathogen,and plant-plant interactions. Some terpenoids are of medicinal value,such as the anti-malaria drug Qinghaosu (artemisinin) which is an endoperoxide sesquiterpene lactone isolated from the traditional herb Artemisia annua. Sesquiterpenes are derived from the cytosolic mevalonate pathway,and sesquiterpene synthases catalyze the key step of converting faraesyl diphosphate into mostly cyclic *** plants expression of sesquiterpene synthase genes is often inducible by the phytohormone jasmonate(JA).We found that in ***,the JA-responsive AP2.family transcription factors—AaERF1 and AaERF2.are involved in transcriptional regulation of AaADS(encoding amorpha-4,11-diene synthase) and CYP71AV1 of the artemisinin *** Arabidopsis thaliana,the bHLH transcription factor MYC2.plays an important role in transcriptional regulation of AtTPS2. and AtTPS11,both are responsible for floral production of volatile ***,in addition to JA, the growth regulator gibberellin(GA) is also able to induce the AtTPS2. and AtTPS11 ***2.interacts with DELLA proteins which are GA signaling repressors, integrating both GA and JA signals into transcriptional regulation of sesquiterpene synthase *** that secondary metabolites vary among different organs and along with the plant life cycle,further research will be directed to explore the relationship between plant development and secondary metabolism regulation.

作者： SUN Shi-yong HAO Wei LIN Hong-xuan National Key Laboratory of plant Molecular Genetics Shanghai Institute of Plant Physiology and Ecology Shanghai Institute forBiological Sciences Chinese Academy of Sciences Graduate School of the Chinese Academy of Sciences Shanghai 200032 China

The BIL （backcross inbred line） population derived from the cross between Koshihikari （good eating and cooking quality, japonica） and Kasalath （poor quality, indica） was used to analyze the QTLs for amylose content （AC）, gelatinization temperature （GT）, gel consistency （GC） and protein content （PC）. Eight main-effect QTLs including 2.for AC, 3.for GT, 2.for GC and 1 for PC were identified, Moreover, 2. epistatic QTL pairs including 7 for AC, 5 for GT, 4 for GC and 11 for PC were also detected while for AC and GT, one main-effect QTL with a major gene was detected, respectively. Therefore, the main-effect QTL might be more responsible for the current variation than the epistetic QTL. The result indicated that the main-effect QTL is the primary genetic basis for those traits. However, for PC, the epistatic QTL explained a much greater portion of the total variation than main-effect QTL, suggesting that epistatic loci are the primary genetic basis for such trait. In the experiment, chromosome segment substitution lines （CSSLs） were used to confirm reliabilities of the main effect QTLs detected in BIL population. Of the 8 main-effect QTLs for 4 traits in BIL analysis, 6 were confirmed end 2.remained unconfirmed by CSSLs analysis.

The genera of Nocardia and its close related Rhodococcus and Streptomyces, belonging to actinomycetes, are the high G + C Gram-positive eubacteria with mycelium-producing. We report here a new identified plasmid pXT107 of Nocardia sp. 107, one of the smallest circular plasmid found in Nocardia. The complete nucleotide sequence of pXT107 consisted of 43.5-bp with 65%
