Title: Innovations in Plant Protection by Yoshifumi Hashimoto
Introduction
Yoshifumi Hashimoto is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of plant research, particularly in the area of pest control through genetic engineering. With a total of 2 patents, his work focuses on enhancing plant resistance to insect pests.
Latest Patents
Hashimoto's latest patents include a method of protecting plants by introducing a gene coded for a protein that enhances virus infection of host insects. Recent advances in research on the synergistic effect of mixed baculovirus infections have demonstrated the presence of viral molecules that enhance the early events of infection. The enhancins identified have the function of disrupting the structural integrity of the peritrophic membrane of the midgut of larvae. The enhancin gene was ligated downstream of the CaMV 355 promoter of a binary vector pBI121. With a drug-resistant gene, this gene was introduced to a piece of tobacco leaf from cv. Havana SR1. Out of 37 regenerated plants, 11 were screened by feeding tobacco powder mixed in an artificial diet to 3rd instar larvae. The larval stage was usually delayed by 1 to 3 days compared to control larvae. The larvae did not pupate normally and exhibited irregular morphology, suggesting hormonal disturbances caused by the transgenic tobacco. The introduction of an enhancin gene into plants is an effective method of protecting them from insects due to the disruption of their normal life cycle.
Another patent involves cloning and sequencing certain baculovirus genes encoding polypeptides termed enhancins. These polypeptides are isolated from the occlusion body of certain baculoviruses, such as Trichoplusia ni granulosis virus and Pseudaletia unipuncta granulosis virus, Hawaiian strain. The polypeptides enhance the infectivity of baculoviruses and are useful ingredients in pest control compositions.
