AI Technical Summary
Technical Problem
The flowering period and fruit ripening time of bayberries are easily affected by natural weather, leading to concentrated market ripening and fruit loss. Existing technologies lack effective means of regulation.
Method used
By studying the MrSPL4 gene of bayberry, an overexpression vector was constructed and transformed into plants to promote earlier flowering. The flowering-promoting effect of the MrSPL4 gene was utilized to cultivate transgenic plants with earlier flowering.
Benefits of technology
This method advanced the flowering period of bayberries, avoiding the impact of natural weather on fruit yield and increasing the commercial value and output of the fruit.

Abstract
本发明公开了一种MrSPL4基因及其应用，MrSPL4基因的核苷酸序列如SEQ ID NO.1所示。将所述MrSPL4基因与质粒组合构建表达载体、转入农杆菌，进一步侵染本氏烟草，获得转MrSPL4基因本氏烟，培养发现转MrSPL4基因本氏烟具有早花特性，证实了MrSPL4基因的促开花作用。可将MrSPL4基因应用于培育花期提前的植物，特别是对于杨梅类经济作物，若能使其花期提前，则可使果期提前避免“梅雨”等自然天气对果实产量的影响，也可提高果实的商业价值。
