TxE 2004:
|
This is a Prunus reference map in an almond (cv. Texas) x peach (cv. Earlygold) F2 progeny. The current map has 562 markers, covering 519 cM (average density, 0.92 cM per marker). TxE map was originally reported as a saturated linkage map of 246 markers (235 RFLPs and 11 isozymes)in the expected eight linkage group by Joobeur et al (1998). An updated map with an addition of 96 simple sequence repeats (SSRs) has been reported by Aranzana et al (2003) and the current map with 220 additional markers (89 SSRs, five sequence-tagged sites, and 126 RFLPs has been reported by Dirlewanger et al (2004). |

Peach Transcriptome map:
|
A putative peach unigene set consisting of 3842 ESTs was defined by the assembly and annotation of 9984 ESTsfrom a peach cDNA library of developing fruit mesocarp. Using core markers from the general Prunus genetic map, BAC clones are anchored on the genetic map, providing a framework for the construction of a transcript map. A transcript map was developed by hybridizing 1,236 ESTs from the putative peach unigene set. ESTs are anchored to genetic maps when they are hybridized to BACs that have previously been hybridized to genetic markers. ESTs are also anchored to genetic maps when the EST-hybridizing BACs belong to a BAC contig that contains genetically anchored BACs. |

Prunus resistance map:
|
A candidate gene approach was implemented for locating resistance loci in the genome of peach. Candidate genes representing NBS-LRR, kinase, transmembrane domain classes, as well as, pathogen response (PR) proteins and resistance-associated transcription factors were hybridized to a peach BAC library and mapped by using the peach physical map database and the Genome Database for Rosaceae (GDR). A resistance map for Prunus was generated and currently contains 42 map locations for putative resistance regions distributed among 7 of the 8 linkage groups. |
