gLRR Resistance-like gene neighborhood. On fosmid 49M15, the evident probe target was a disease resistance protein family gene at site 4a. Site 4b has Blastx homology to a squalene epoxidase gene. Both genes are on the plus strand. Neither the stop codon of gene 4a nor the start codon of gene 4b could be confidently determined. Moreover, the two respective coding regions are bridged by a matching 1447 bp Malus cDNA sequence [GenBank: EG631376], suggesting that region 4a + 4b may be transcribed as a single unit. Note that regions 4a-4b are merged into one gene prediction by all six FGENESH models. Gene site 5 encodes a putative transposable-element-related protein, and is the site of an hAT repetitive element. Gene site 3 (unknown protein) has complete, top-tier F-EST coverage, and was modeled.
