Abstract：Lipoxygenases are important dioxygenases in cellular organisms.LOX genes contribute to plant development,biotic and abiotic stress tolerance.Eighteen AdLOX genes,named AdLOX1 ~18,were i-dentified from Arachis duranensis genome.Eighteen AiLOX genes,named AiLOX1 ~18,were identified from Arachis ipaёnsis genome.Among them,the coding sequences of AdLOX5,AdLOX7,AiLOX8 and AiLOX18 genes contained premature translational -termination codon,and the length of AiLOX9 gene was too short,it suggested that they were pseudogenes.The chromosomal location results showed that AdLOX and AiLOX genes mainly distributed in chromosome 2,3,6,8,9 and 1 0.The orthologous gene pairs located at the same or similar position in A.duranensis and A.ipaёnsis chromosomes,respectively.Functional study of LOX gene in other plant species and phylogenetic analysis indicated that AdLOX6,AdLOX9,AdLOX11,AdLOX12,Ad-LOX17,AiLOX1,AiLOX4,AiLOX6,AiLOX16 and AiLOX17 genes were possibly involved in plant disease re-sistance.Promoter analysis results also testified that.The gene selection pressure results indicated that AdLOX and AiLOX genes experienced purify selection during the evolutionary process.
