Camellia oleifera is an important edible oil woody plant in China. Lack of useful molecular markers hinders current genetic research on this tree species. Transcriptome sequencing of developing C. oleifera seeds generated 69,798 unigenes. A total of 6949 putative microsatellites were discovered among 6042 SSR-containing unigenes. Then, 150 simple sequence repeats (SSRs) were evaluated in 20 varieties of C. oleifera.
Pinus massoniana (Masson’s pine) is a widespread tree species in central and southern China and northern Vietnam; it is valued for rosin and paper production. Despite the significant economic value of Masson's pine, little work has been done on its molecular genetics. We developed 318 SSR primers from genome sequences of P. massoniana, and we identified 10 polymorphic markers. The number of alleles in the population of P. massoniana that we examined ranged from two to four, and the Shannon diversity index ranged from 0.150 to 1.133.
We examined cross-species transferability and usefulness of six nuclear microsatellite markers developed in consubgeneric eastern white pine (Pinus strobus) with regard to ecologically and commercially important Mexican white pine species of conservation genetics concern: Pinus chiapensis (Mart.) Andresen, P. flexilis James, P. strobiformis Engelm., P. ayacahuite Ehrenb. Ex Schltdl, and P. ayacahuite var. veitchii (Roezl) G.R. Shaw.
The aim of this study was to identify single-nucleotide polymorphisms (SNPs) in buffaloes associated with milk yield and content, in addition to somatic cell scores based on the cross-species transferability of SNPs from cattle to buffalo. A total of 15,745 SNPs were analyzed, of which 1562 showed 1% significance and 4742 with 5% significance, which were associated for all traits studied.
