The split-seed explant can also be used to generate calli and/or multiple shoots, and rooted plantlets.

The invention relates to an application of a Zea mays grain transcription factor in the aspect of regulation and control of alcohal-soluble proteins. The factor comprises a base sequence shown in SEQ ID NO: 1. The protein ZmbZIP22 encoded by the sequence can be directly bonded to a 27kDa gamma-gliadin promoter and activate the 27kDa gamma-gliadin promoter. Gene-deficient mutant plants are obtained through carrying out Zea mays immature-embryo conversion by taking a gene fragment, shown in SEQ ID NO: 2, of ZmbZIP22 as a guide RNA by using a CRISPR-Cas9 technology. Compared with wild type grains, transgenic mutants have Zea mays grains with irregular and relative-thin protein body shells, the content of alcohal-soluble proteins in mature grains is remarkably lowered, the content of essential amino acids such as lysine, which are deficient to the conventional Zea mays, in the mature grains is remarkably increased, and thus, the nutritional quality of Zea mays is improved.

This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals.

The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the gene from corn lines carrying said gene into other corn lines that do not carry said gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.
