【Objective 】 Single nucleotide polymorphisms( SNPs) within candidate genes involved in growth and resin biosynthesis of loblolly pine,Pinus taeda,were screened and analyzed,preparing technical basis for later marker-assisted breeding.【Method】The candidate unigenes related to auxin,gibberellins,cytokinins or pinene synthesis were selected from loblolly pine c DNA library using bioinformatics.The sequences of eight candidate genes from 36 loblolly pine individuals were aligned and compared using MEGA5. 0 and ...
