摘要:

以‘长富2’苹果片红芽变的果皮为试材,克隆了溶质转运蛋白家族基因MdSLC35F2-like(Solute Carrier Family 35 Member F2-like)的开放阅读框(ORF),其长度为1 041 bp,编码346个氨基酸。利用在线软件进行生物信息分析,该蛋白是1个稳定的疏水性α螺旋跨膜蛋白,定位于细胞膜。同源性分析表明,MdSLC35F2-like与白梨的PbSLC35F1-like同源性最高;系统进化分析表明,其与白梨的进化亲缘关系最近,与可可、巨桉的进化亲缘关系最远。分析‘长富2号’及其片红芽变果实着色期花青苷的积累与MdSLC35F2-like表达量的变化,结果表明,摘袋后MdSLC35F2-like表达量在‘长富2号’及其2个片红芽变果实果皮中均呈先升高后降低的趋势,在摘袋后3 d表达量最高,而后逐渐降低,2个芽变材料均显著高于其野生型,表达量与花青苷含量呈正相关关系。在其他颜色品种上进行验证分析,MdSLC35F2-like在红色果皮品种‘烟富3号’果皮中的表达量极显著高于绿色果皮品种‘金陵’,在红色果肉品种‘红色之爱’果肉中的表达量显著高于白肉品种‘烟农早富’。以上结果进一步证明MdSLC35F2-like与花青苷积累有关。

Abstract:

Anthocyanin is the main pigment affecting the skin color of apple fruit. In our previous study,MdSLC35F2-like was expressed at higher levels in the‘Nagafu 2’apple red bud mutant than in the wild-type. The open reading frame(ORF)of MdSLC35F2-like was cloned,it is 1 041bp,encoding 346 amino acids,which was predicted to be a hydrophobic α helix transmembrane protein with the highest homology to the PbSLC35F1-like of Pyrus × bretschneideri. Phylogenetic analysis showed that it had the closest evolutionary relationship with P. × bretschneideri,and the furthest evolutionary relationship with Theobroma cacao and Eucalyptus grandis. MdSLC35F2-like sequence and its expression rules before and after the fruit bagging were analyzed. After unbagging,the expression level of MdSLC35F2-like increased firstly,and then decreased with a peak on the third day. The expression level of MdSLC35F2-like in the two kinds of buds was significantly higher than that of‘Nagafu 2’. The above results indicated that the expression level of MdSLC35F2-like gene is positively correlated with anthocyanine content. Meanwhile,its expression levels in different color apple cultivars were compared. The expression of MdSLC35F2-like in red peel cultivars was significantly higher than that in green peel cultivars,and the expression level in red pulp cultivars was higher than that in non-red pulp cultivars. It suggests that MdSLC35F2-like may participate in the anthocyanine accumulation process.
