Problems solved by technology

However, the main genes controlling the traits of blue grains in triticale are still unclear. Therefore, it is necessary to compare the differences in structural genes and their transcription factors in the aleurone layers of blue grains and white grains in triticale, and to compare the differences in their transcription levels.

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Aiming at the fact that the key genes related to anthocyanin synthesis in triticale have not been found and studied so far, the inventors found that the main reason is that the current genes related to anthocyanin synthesis are obtained from the leaf transcriptome database, and the genes in the aleurone layer are omitted. specifically expressed genes. For this reason, the inv...

Abstract

The invention discloses a triticale gene, and an encoding protein and applications thereof. The gene is a major gene which can regulate blue grain traits of triticale and can regulate the synthesis ofanthocyanins; and the amino acid sequence of the protein of the triticale is shown as SEQ ID NO. 1, and the nucleotide sequence is shown as SEQ ID NO. 2. Bases can be provided for studying the synthetic mechanism of rye anthocyanins, and directions and target spots can also be provided for gene engineering means to transform plants so as to enhance the content of the anthocyanins.

Description

technical field [0001] The invention belongs to the field of plant genetic engineering, and specifically relates to a gene TsMYC1 regulating anthocyanin synthesis and metabolism, including a recombinant plasmid of the gene, a host and application thereof. Background technique [0002] Blue-grained triticale is mainly due to the massive accumulation of anthocyanins in the aleurone layer (Bartl et al., 2015). As an important secondary metabolite in plants, anthocyanins mainly regulate plant growth and development, thereby protecting plants against external stress (Grausgruber, et al., 2018). In addition, anthocyanins endow plant organs with different colors, which can attract insects to pollinate them (Li, et al., 2019). Anthocyanin is a natural food additive, and the processed product has the functions of anti-oxidation, anti-cancer, anti-aging, and enhancing immunity (Su, et al., 2018). In the genetic breeding process of wheat crops, the blue grain trait can be used to ide...
