Transcriptome sequencing of Hevea brasiliensis for development of microsatellite markers and construction of a genetic linkage map.

To obtain more information on the Hevea brasiliensis genome, we sequenced the transcriptome from the vegetative shoot apex yielding 2 311 497 reads. Clustering and assembly of the reads produced a total of 113 313 unique sequences, comprising 28 387 isotigs and 84 926 singletons. Also, 17 819 expressed sequence tag (EST)-simple sequence repeats (SSRs) were identified from the data set.

Single nucleotide polymorphism marker development in the rubber tree, Hevea brasiliensis (Euphorbiaceae).

Premise Of The Study: We demonstrated the application of high-throughput 454 sequencing technology in the identification of single nucleotide polymorphism (SNP) markers in Hevea brasiliensis.

Methods And Results: A total of 5883 putative SNP positions were discovered in silico, and 10 biallelic SNP markers were validated from 454-derived EST sequences. The polymorphism information content (PIC) and the observed heterozygosity (H(o)) ranged from 0.

Characterization of the complete chloroplast genome of Hevea brasiliensis reveals genome rearrangement, RNA editing sites and phylogenetic relationships.

Rubber tree (Hevea brasiliensis) is an economical plant and widely grown for natural rubber production. However, genomic research of rubber tree has lagged behind other species in the Euphorbiaceae family. We report the complete chloroplast genome sequence of rubber tree as being 161,191 bp in length including a pair of inverted repeats of 26,810 bp separated by a small single copy region of 18,362 bp and a large single copy region of 89,209 bp.

Characterization of microsatellites and gene contents from genome shotgun sequences of mungbean (Vigna radiata (L.) Wilczek).

Background: Mungbean is an important economical crop in Asia. However, genomic research has lagged behind other crop species due to the lack of polymorphic DNA markers found in this crop. The objective of this work is to develop and characterize microsatellite or simple sequence repeat (SSR) markers from genome shotgun sequencing of mungbean.

WASP: a Web-based Allele-Specific PCR assay designing tool for detecting SNPs and mutations.

Background: Allele-specific (AS) Polymerase Chain Reaction is a convenient and inexpensive method for genotyping Single Nucleotide Polymorphisms (SNPs) and mutations. It is applied in many recent studies including population genetics, molecular genetics and pharmacogenomics. Using known AS primer design tools to create primers leads to cumbersome process to inexperience users since information about SNP/mutation must be acquired from public databases prior to the design.
