Title: Innovations of Hai Ping Hong in Plant Genetics
Introduction
Hai Ping Hong is a notable inventor based in Saskatoon, Canada. He has made significant contributions to the field of plant genetics, particularly through his innovative work on gene promoters in Brassica species. With a total of 2 patents, his research has implications for the temporal and spatial control of gene expression in plants.
Latest Patents
Hai Ping Hong's latest patents include two significant innovations. The first patent is for a Brassica sp. gene promoter that is highly expressed during tapetum development. This genomic clone was isolated to direct expression in the tapetum. When fused with the GUS gene and introduced into B. napus via Agrobacterium-mediated transformation, it successfully controlled GUS expression in transgenic B. napus plants. Expression was observed from bud lengths of 2-3 mm, peaking at 4-5 mm, and declining to undetectable levels at the open flower stage. Notably, there was no GUS expression in other tissues such as root, stem, leaf, sepal, petal, or pistil. This promoter is expected to be useful for controlling gene expression in plants.
The second patent involves a Brassica sp. polygalacturonase gene promoter. This genomic clone directs high levels of transcription in pollen. Similar to the first patent, when fused with the GUS gene and introduced into B. napus, it controlled GUS expression in microspores and pollen. Expression occurred between the late uninucleate microspore stage and the mature pollen grain stage, with GUS activity also identified in tapetal tissue at the binucleate microspore stage. Again, there was no GUS expression in other tissues. This promoter will also be beneficial for the temporal and spatial control of endogenous gene expression in plants.
