Title: Innovations of Keqiang Wu in Plant Biotechnology

Introduction

Keqiang Wu is a notable inventor based in Nepean, Canada, recognized for his contributions to plant biotechnology. He has been instrumental in developing innovative methods and regulatory elements that enhance gene expression in plants. With a total of four patents to his name, Wu's work has significant implications for agricultural science and transgenic plant development.

Latest Patents

One of Wu's latest patents involves the discovery of cryptic regulatory elements obtained from plants. This invention focuses on T-DNA tagging with a promoterless β-glucuronidase (GUS) gene, which generates transgenic plants that express GUS activity specifically in developing seed coats or constitutively. The cloning and deletion analysis of the GUS fusion revealed that the promoter responsible for seed coat specificity is located in the plant DNA proximal to the GUS gene. This research demonstrated that the seed coat-specificity of GUS expression results from T-DNA insertion next to a cryptic promoter, which is useful for controlling gene expression in developing seed coats.

Another significant patent pertains to the regulatory region of a lipid transfer protein (LtpW1) derived from the aleurone tissue of wheat. This invention encompasses a regulatory region that can express heterologous genes within aleurone cells of a plant. The truncated LtpW1 regulatory region exhibits constitutive activity in both monocot and dicot plants. Additionally, this patent includes vectors comprising these regulatory regions operatively linked with heterologous genes, as well as plant cell cultures and transgenic plants that utilize these vectors.
