综述了与彩色马铃薯色素产生与分布相关基因座的观念起源、种类、功能和染色体定位.与彩色马铃薯色素相关基因座的观念起源于试图解释四倍体和二倍体马铃薯块茎和其他部位颜色呈现遗传行为的两个遗传模式.与彩色马铃薯色素相关的13个基因座可划分为4类,第1、第2和第3类分别与马铃薯花色苷的合成、酰化和分布有关,第4类与马铃薯类胡萝卜素的产生相关.基因座I,P,R和Y分别编码一个MYB结构域转录因子、类黄酮3′,5′-羟化酶、二氢黄酮醇4-还原酶和β-胡萝卜素羟化酶.基因座之间复杂多样的互作综合决定了彩色马铃薯色素特别是花色苷的产生与分布.基因座D和R定位在马铃薯的2号染色体上,E,F,I和PSC在10号染色体上,P在11号染色体上,Y在3号染色体上.可为彩色马铃薯颜色呈现的遗传机理探索提供参考.
綜述瞭與綵色馬鈴藷色素產生與分佈相關基因座的觀唸起源、種類、功能和染色體定位.與綵色馬鈴藷色素相關基因座的觀唸起源于試圖解釋四倍體和二倍體馬鈴藷塊莖和其他部位顏色呈現遺傳行為的兩箇遺傳模式.與綵色馬鈴藷色素相關的13箇基因座可劃分為4類,第1、第2和第3類分彆與馬鈴藷花色苷的閤成、酰化和分佈有關,第4類與馬鈴藷類鬍蘿蔔素的產生相關.基因座I,P,R和Y分彆編碼一箇MYB結構域轉錄因子、類黃酮3′,5′-羥化酶、二氫黃酮醇4-還原酶和β-鬍蘿蔔素羥化酶.基因座之間複雜多樣的互作綜閤決定瞭綵色馬鈴藷色素特彆是花色苷的產生與分佈.基因座D和R定位在馬鈴藷的2號染色體上,E,F,I和PSC在10號染色體上,P在11號染色體上,Y在3號染色體上.可為綵色馬鈴藷顏色呈現的遺傳機理探索提供參攷.

This paper summarized the idea origin,category,functions and chromosomal locations of the gene loci involved in the production and distribution of the pigments in colored potatoes. The idea of the gene loci related to the pigments in colored potatoes originated from the two genetic models which attempted to explain the inheritant behaviors of the colorations of the stem tubers and other parts of tetraploid and diploid potatoes. The overall thirteen gene loci related to the pigments in colored potatoes could be classified into four kinds. The first,second and third kinds were related to the synthesis,acylation and distribution of the potato anthocyanins respectively,and the fourth kind was related to the production of the potato carotenoids. Locus I,P,R and Y encoded a MYB-domain transcription factor,flavonoid 3′,5′-hydroxylase,dihydroflavonol 4-reductase and β-carotene hydroxylase respectively. Various and complicated interactions among the gene loci synthetically determined the production and distribution of the pigments,especially the anthocyanins,in colored potatoes. Locus D and R were located on Chromosome 2 of potato,E,F,I and PSC on Chromosome 10,P on Chromosome 11,and Y on Chromosome 3. This paper could provide a reference for the exploration on the genetic mechanism of the colorations of colored potatoes.
