The protein kinase AtMPK3,a component of the MAP kinase cascade,plays an important role in stress signal transduction in plant cells. To clarify how AtMPK3 is regulated at the transcriptional level in response to various environmental factors, the 1016-bp promoter sequence upstream of the transcription start site of the AtMPK3 gene was isolated. Analyses of the promoter sequence using plant promoter databases revealed that the AtMPK3 promoter contains many potential cis-acting elements involved in environmental stress responses. We constructed four deletion mutants of the AtMPK3 promoter, and introduced the intact and truncated promoter sequences fused to the β-glucuronidase (GUS) gene into Arabidopsis. GUS histochemical staining and quantitative fluorometric GUS assays were performed to visualize and compare the expression patterns in response to different environmental stimuli. The region between-188 and-62 upstream of the transcription start site was identified as the essential DNA sequence of the AtMPK3 promoter for responses to drought, high salinity, low temperature, and wounding. These results advance our understanding of the molecular mechanisms controlling AtMPK3 expression in response to different environmental stimuli.

In rice, the characterization of OsEBP-89 is inducible by various stress- or hormone-stimuli, including ethylene, abscisic acid (ABA), jasmonate acid (JA), drought and cold. Here, we report the investigation of essential DNA region within OsEBP-89 promoter for methyl jasmonic acid (MeJA) induction. PLACE analysis indicates that this promoter sequence contains multiple potential elements in response to various stimuli. First, we fused this promoter with GUS gene and analyzed its expression under MeJA treatment through Agrobacterium infiltration mediating transient expression in tobacco leaves. Our results revealed that this chimeric gene could be inducible by MeJA in tobacco leaves. To further de- termine the crucial sequences responsible for MeJA induction, we generated a series of deletion pro- moters which were fused with GUS reporter gene respectively. The results of transient expression of GUS gene driven by these mutant promoters show that the essential region for MeJA induction is po- sitioned in the region between -1200 and -800 in OsEBP-89 promoter containing a G-box (?1127), which is distinct from the essential region containing ERE (?562) for ACC induction. In all, our finding is helpful in understanding the molecular mechanism of OsEBP-89 expression under different stimuli.

＜正＞ There are over 23 thousands soybean accessions in China, where has the most soybean germplasm in the world. It becomes urgent task to evaluate and utilize the collection efficiently. Based on the passport data and agronomic traits of these germplasm, a total of 20 sampling methods were compared and the best one was subjected to collection samples. The primary core collection was consisted of the samples selecting by the best method and artificially adding few accessions with traits that not included. Then this collection was analyzed by a core set of SSR loci, which identified with 80 autumn soybean accessions and confirmed with 190 random soybean accessions from the whole country. The core collection established with both SSR data
