Plants with altered root architecture, related constructs and methods involving genes encoding exostosin family polypeptides and homologs thereof

摘要

Isolated polynucleotides and polypeptides and recombinant DNA constructs particularly useful for altering root structure of plants, compositions (such as plants or seeds) comprising these recombinant DNA constructs, and methods utilizing these recombinant DNA constructs. The recombinant DNA construct comprises a polynucleotide operably linked to a promoter functional in a plant, wherein said polynucleotide encodes a polypeptide useful for altering plant root architecture.

主权项

1. A plant comprising in its genome a recombinant DNA construct comprising a polynucleotide operably linked to at least one heterologous regulatory element, wherein said polynucleotide encodes a polypeptide having an amino acid sequence of at least 95% sequence identity, based on the Clustal V method of alignment, when compared to SEQ ID NO: 34 and wherein said plant exhibits increased root biomass when compared to a control plant not comprising said recombinant DNA construct.
