Title: Innovations by Desen Zheng in Biological Control of Crown Gall Disease

Introduction

Desen Zheng is an accomplished inventor based in Geneva, NY (US). He has made significant contributions to the field of biological control, particularly in the management of crown gall disease on grapevines. His innovative work has led to the development of novel derivatives that enhance plant health and productivity.

Latest Patents

Desen Zheng holds a patent for the biological control of crown gall disease on grapevines. The patent details the derivatives of strain F2/5, which were generated through homologous recombination with an internal fragment of targeted genes. This process resulted in gene disruption by the insertion of a copy of the suicide vector pVIK165. The disrupted genes include F-avi5813, which encodes a phosphopantetheinyltransferase, F-avi4329, which encodes an aminotransferase, and F-avi0838 (rirA), which encodes an iron-responsive transcriptional regulator. These derivatives effectively control crown gall on grapevines without inducing root necrosis, while also enhancing root development and callus formation. Furthermore, it has been demonstrated that the F2/5 derivatives are necrosis-negative on young stem explants.

Career Highlights

Desen Zheng is affiliated with Cornell University, where he continues to engage in research and innovation. His work has garnered attention for its practical applications in agriculture, particularly in improving the health of grapevines affected by crown gall disease.

Collaborations
