主　　题：GmJAz3 response regulator seed size seed weight soybean 

摘      要：Seed weight is usually associated with seed size and is one of the important agronomic traits that determine *** of seed weight control is limited,especially in soybean *** we show that Glycine max JASMONATEZIM DOMAIN 3(GmJAZ3),a gene identified through gene co-expression network analysis,regulates seed-related traits in *** of GmJAZ3 promotes seed size/weight and other organ sizes in stable transgenic soybean plants likely by increasing cell ***3 interacted with both *** RESPONSE REGULATOR 18a(GmRR18a)and GmMYC2a to inhibit their transcriptional activation of cytokinin oxidase gene *** CYTOKININ OXIDASE 3-4(GmCKX3-4),which usually affects seed ***,the GmRR18a binds to the promoter of GmMYC2a and activates GmMYC2a gene *** GmJAZ3-overexpressing soybean seeds,the protein contents were increased while the fatty acid contents were reduced compared to those in the control seeds,indicating that the GmJAZ3 affects seed size/weight and *** variation in JAZ3 promoter region was further analyzed and Hap3 promoter correlates with higher promoter activity,higher gene expression and higher seed *** Hap3 promoter may be selected and fixed during soybean ***3 orthologs from other plants/crops may also control seed size and *** together,our study reveals a novel molecular module GmJAZ3-GmRR18a/GmMYC2a-GmCKXs for seed size and weight control,providing promising targets during soybean molecular breeding for better seed traits.
