1Mutants, Overexpressors, and Interactors of Arabidopsis Plastocyanin Isoforms: Revised Roles of Plastocyanin in Photosynthetic Electron Flow and Thylakoid Redox State显示文摘二相应 plastocyanin isoforms 被基因 PETE1 和 PETE2 编码为 Arabidopsis thaliana 的原子染色体。PETE2 抄本被表示在更加高水平和 PETE2 蛋白质是更丰富的 isoform。在 PETE 基因的空变化导致了植物,指明的 pete1 和 pete2,与减少的 plastocyanin 内容。尽管有在超过 90% 减少 plastocyanin 层次,而 pete1 大美人种,然而,它的自己上的一个 pete2 0 变化仅仅稍微影响光合作用和生长的率,与大约 6080% 野类型的 plastocyanin 水平,没显示出任何改变。因此, plastocyanin 集中不在最佳的生长条件下面为光合的电子流动正在限制,也许为蛋白质暗示另外的可能的生理的角色。确实, plastocyanin 以前被建议了在 thylakoid 氧化还原作用反应与细胞色素 c6A (Cyt c6A ) 合作,但是我们不为在二蛋白质之间的一个物理相互作用发现证据,用在酵母的相互作用试金。我们在酵母相互作用试金观察了 Cyt c6A 的 homodimerization,而且 Cyt c6A homodimers 没能与 plastocyanin 交往。而且, atc6-1 pete1 的 phenotypic 分析和 atc6-1 pete2 加倍异种,每缺乏的 Cyt c6A 并且二编码 plastocyanin 基因之一,没能揭示任何基因相互作用。在 pete1 pete2 的 PETE1 或 PETE2 的 Overexpression 在实质上野类型的光合的性能的两倍猛烈变异的背景结果,排除二 plastocyanin isoforms 能在 thylakoid 有不同函数的可能性电子流动。Paolo Pesaresi Michael Scharfenberg Martin Weigel Irene Granlund Wolfgang R Schroder Giovanni Finazzi Fabrice Rappaport Simona Masiero Antonella Furini Peter Jahns Dario Leister 2009Molecular Plant2009,2,2:7
2Major-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 2020Horticulture Research2020,7,1:2
