The availability of expressed sequence data derived from gene discovery programs enables mining for simple sequence repeats (SSR), providing useful genetic markers for crop improvement. These markers are inexpensive, require minimal labour to produce and can frequently be associated with functionally annotated genes. This study presents the development and characterization of 16 expressed sequence tags (EST)‐SSR markers from Brassica juncea and their cross‐amplification across Brassica species. Sixteen primer pairs were assessed for polymorphism in all genomes of the diploid and amphidiploid Brassica species. The markers show reliable amplification, considerable polymorphism and high transferability across species, demonstrating the utility of EST‐SSRs for genetic analysis of brassicas. 相似文献

The availability of expressed sequence data derived from gene discovery programs enables mining for simple sequence repeats (SSR), providing useful genetic markers for crop improvement. These markers are inexpensive, require minimal labour to produce and can frequently be associated with functionally annotated genes. This study presents the development and characterization of 24 expressed sequence tags (EST)‐SSR markers from Brassica napus and their cross‐amplification across Brassica species. The markers show reliable amplification, genome specificity and considerable polymorphism, demonstrating the utility of EST‐SSRs for genetic analysis of wild Brassica populations and commercial Brassica germplasm. 相似文献

HUMAN α-amylase (α-1,4-glucan 4-glucanohydrolase, E.C. 3.2.1.1) is primarily in the pancreas and salivary glands and can be detected in serum and urine (UAmy) as well as in saliva (SaAmy) and duodenal secretions. The SaAmy locus (Amy1) has at least three mutant alleles with the combined frequency of electrophoretic variant phenotypes totalling approximately 0.01 in Caucasian Americans1. Subsequently, UAmy was shown to be a convenient source of pancreatic amylase. The pancreatic amylase locus (Amy2) has at least two mutant alleles in Caucasian and Afro-Americans2. The variant UAmy Ss is common in Caucasians whereas UAmy Sp has been found only in Afro-Americans; the frequency of variant phenotypes is 0·086 in each population2. 相似文献
