Gene for controlling tomato fruit shape and cloning method and application thereof

Abstract

The invention relates to a gene for controlling tomato fruit shape and a cloning method and an application thereof. A cDNA nucleotide sequence of the tomato fruit shape regulating gene is shown as SEQID NO: 1 or SEQ ID NO: 2. The gene can regulate the formation of elliptical fruit, round fruit and oblate fruit in tomato, and can be applied in changing tomato fruit shape and cultivating new varieties.

Description

technical field [0001] The invention relates to the technical field of plants, in particular to a gene controlling tomato fruit shape and application thereof. Background technique [0002] Fruit shape is an agronomic trait that breeding focuses on. Among them, for vegetable crops with fresh fruits as edible organs, fruit shape is an important commodity trait. At present, the research on fruit shape in plants can be roughly divided into two categories, one is research on dry fruits such as caryopsis of rice and Arabidopsis silique, and the other is on fleshy fruit represented by tomato. [0003] In rice, the shape of the caryopsis is often consistent with the shape of the rice grain, so the appearance quality of the caryopsis has always been highly concerned by breeders. Chinese scholars have long noticed that the appearance of rice may be related to the quality of rice, and based on this, China's cultivated rice is roughly divided into indica and japonica. In general, the...

Problems solved by technology

[0011] That is to say, although the oblate fruit shape of tomato has been preliminarily understood, little is known about the genes regulating oblong fruit, and the genes that simultaneously regulate round, oblate, and oval fruits have not been reported.
