| 1 | Molecular genetics and genomics of the Rosoideae: state of theart and future perspectives显示文摘The Rosoideae is a subfamily of the Rosaceae that contains a number of species of economic importance,including the soft fruit species strawberry(Fragaria 3ananassa),red(Rubus idaeus)and black(Rubus occidentalis)raspberries,blackberries(Rubus spp.)and one of the most economically important cut flower genera,the roses(Rosa spp.).Molecular genetics and genomics resources for the Rosoideae have developed rapidly over the past two decades,beginning with the development and application of a number of molecular marker types including restriction fragment length polymorphisms,amplified fragment length polymorphisms and microsatellites,and culminating in the recent publication of the genome sequence of the woodland strawberry,Fragaria vesca,and the development of high throughput single nucleotide polymorphism(SNP)-genotyping resources for Fragaria,Rosa and Rubus.These tools have been used to identify genes and other functional elements that control traits of economic importance,to study the evolution of plant genome structure within the subfamily,and are beginning to facilitate genomic-assisted breeding through the development and deployment of markers linked to traits such as aspects of fruit quality,disease resistance and the timing of flowering.In this review,we report on the developments that have been made over the last 20 years in the field of molecular genetics and structural genomics within the Rosoideae,comment on how the knowledge gained will improve the efficiency of cultivar development and discuss how these advances will enhance our understanding of the biological processes determining agronomically important traits in all Rosoideae species. | Sara Longhi Lara Giongo Matteo Buti Nada Surbanovski Roberto Viola Riccardo Velasco Judson AWard Daniel J Sargent | 2014 | Horticulture Research2014，1，1： | 7 |
| 2 | Major-effect candidate genes identified in cultivated strawberry(Fragaria×ananassa Duch.)for ellagic acid deoxyhexoside and pelargonidin-3-O-malonylglucoside biosynthesis,key polyphenolic compounds显示文摘Strawberries are rich in polyphenols which impart health benefits when metabolized by the gut microbiome,including anti-inflammatory,neuroprotective,and antiproliferative effects.In addition,polyphenolic anthocyanins contribute to the attractive color of strawberry fruits.However,the genetic basis of polyphenol biosynthesis has not been extensively studied in strawberry.In this investigation,ripe fruits from three cultivated strawberry populations were characterized for polyphenol content using HPLC-DAD-MSn and genotyped using the iStraw35k array.GWAS and QTL analyses identified genetic loci controlling polyphenol biosynthesis.QTL were identified on four chromosomes for pelargonidin-3-O-malonylglucoside,pelargonidin-3-O-acetylglucoside,cinnamoyl glucose,and ellagic acid deoxyhexoside biosynthesis.Presence/absence of ellagic acid deoxyhexoside and pelargonidin-3-O-malonylglucoside was found to be under the control of major gene loci on LG1X2 and LG6b,respectively,on the F.×ananassa linkage maps.Interrogation of gene predictions in the F.vesca reference genome sequence identified a single candidate gene for ellagic acid deoxyhexoside biosynthesis,while seven malonyltransferase genes were identified as candidates for pelargonidin-3-O-malonylglucoside biosynthesis.Homologous malonyltransferase genes were identified in the F.×ananassa‘Camarosa’genome sequence but the candidate for ellagic acid deoxyhexoside biosynthesis was absent from the‘Camarosa’sequence.This study demonstrated that polyphenol biosynthesis in strawberry is,in some cases,under simple genetic control,supporting previous observations of the presence or absence of these compounds in strawberry fruits.It has also shed light on the mechanisms controlling polyphenol biosynthesis and enhanced the knowledge of these biosynthesis pathways in strawberry.The above findings will facilitate breeding for strawberries enriched in compounds with beneficial health effects. | Jahn Davik Kjersti Aaby Matteo Buti Muath Alsheikh NadaŠurbanovski Stefan Martens Dag Røen Daniel James Sargent | 2020 | Horticulture Research2020，7，1： | 2 |
