Abstract
Official abstract text for this publication.
The present disclosure relates to a composition for promoting plant growth containing an YxaL protein and a method for mass-producing an YxaL protein. The YxaL protein may be expressed constitutively and in large amounts in a recombinant transformed cell line. When the YxaL protein is applied to seed soaking treatment, root development is improved, and the expression of plant genes involved in root growth is improved in favor of plant growth. Thus, the YxaL protein may be effectively used to promote plant growth.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for germinating a plant seed of Arabidopsis thaliana or Oryza sativa , comprising the steps of: (1) isolating a YxaL protein; (2) soaking the plant seed in a soaking solution containing the isolated YxaL protein; and (3) germinating the soaked plant seed; wherein the isolated YxaL protein is obtained from a Bacillus velezensis strain GH1-13; the isolated YxaL protein comprises the amino acid sequence of SEQ ID NO: 20; and the germinated seed has longer lateral root and hair root compared to a plant seed of Arabidopsis thaliana or Oryza sativa that is not soaked in the soaking solution containing the isolated YxaL protein.
