Abstract

Abscisic acid (ABA) plays a crucial role in regulating the ripening of non-climacteric strawberry fruit. In the present study, ABA was confirmed to promote strawberry ripening and induce the down-regulation of . The transient silence of in strawberries promoted fruit ripening and induced the content of anthocyanin and soluble pectin but reduced firmness and protopectin through a tobacco rattle virus-induced gene silencing technique. In parallel with the accelerated ripening, the genes were significantly induced in the transiently modified fruit, including anthocyanin-related , , , , and , softening-related and , and aroma-related and In addition, the interaction between and ABA-related transcription factors was researched. Yeast one-hybrid analysis indicated that the promoter could interact with FaABI5-5, FaTRAB1, and FaABI5. Furthermore, dual-luciferase assay suggested that FaTRAB1 could actively bind with the promoter, resulting in the decreased expression of . In brief, these results suggest that the ABA-dependent ripening of strawberry fruit was probably inhibited through inhibiting expression by the active binding of transcript FaTRAB1 with the promoter.

摘要

脱落酸(ABA)在调控非跃变型草莓果实成熟过程中起着关键作用。在本研究中,ABA被证实可促进草莓成熟并诱导[具体基因名称未给出]的下调。通过烟草脆裂病毒诱导的基因沉默技术,草莓中[具体基因名称未给出]的瞬时沉默促进了果实成熟,诱导了花青素和可溶性果胶的含量增加,但降低了硬度和原果胶含量。与加速成熟同时,在瞬时修饰的果实中,包括花青素相关的[具体基因名称未给出]、[具体基因名称未给出]、[具体基因名称未给出]、[具体基因名称未给出]和[具体基因名称未给出],软化相关的[具体基因名称未给出]和[具体基因名称未给出],以及香气相关的[具体基因名称未给出]和[具体基因名称未给出]等基因被显著诱导。此外,还研究了[具体基因名称未给出]与ABA相关转录因子之间的相互作用。酵母单杂交分析表明,[具体基因名称未给出]启动子可与FaABI5 - 5、FaTRAB1和FaABI5相互作用。此外,双荧光素酶测定表明FaTRAB1可与[具体基因名称未给出]启动子积极结合,导致[具体基因名称未给出]表达降低。简而言之,这些结果表明,草莓果实依赖ABA的成熟可能是通过转录因子FaTRAB1与[具体基因名称未给出]启动子的积极结合抑制[具体基因名称未给出]表达来实现的。
