'''Hari Sharan Karki''' is an American plant pathologist and microbiologist specializing in plant-microbe interactions, with a focus on rice and soybean pathogens. He has held research positions at Louisiana State University (LSU) and the United States Department of Agriculture (USDA).<ref>https://www.ars.usda.gov/people-locations/person?person-id=60041</ref><ref name=":0">https://bio-protocol.org/userhome.aspx?id=1006311</ref>

== Education and Career ==

Karki completed both his Master of Science (MS) and Doctor of Philosophy (PhD) in Plant Pathology and Crop Physiology at Louisiana State University. His doctoral research, completed in 2013, focused on the virulence mechanisms of Burkholderia glumae and rice resistance to bacterial panicle blight and sheath blight.<ref name=":0" /><ref name=":1">https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0146764</ref>

Following his education, Karki has been involved in research roles at LSU and the USDA, focusing on understanding plant diseases and developing disease-resistant crop varieties.

== Research Focus ==

Karki's research primarily centers on:

1. Bacterial pathogen Burkholderia glumae, which causes bacterial panicle blight (BPB) in rice
2. Identification of virulence factors in pathogens
3. Development of high-throughput methods for virulence testing
4. Soybean pathology and identification of natural genetic diversity for pathogen resistance
5. Potato research, focusing on resistance to Phytophthora infestans (late blight)

His work has contributed significantly to understanding the physiological, biochemical, and molecular characteristics associated with pathogen virulence and plant resistance mechanisms.<ref>https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0052150</ref><ref>https://repository.lsu.edu/gradschool_theses/786/</ref>

== Notable Contributions ==

1. Identified key virulence factors in B. glumae, including toxoflavin, lipase, and motility
2. Developed efficient methods for preliminary assessments of pathogen virulence using onion bulb scales
3. Contributed to the identification of new sources of resistance to late blight in wild potato species
4. Advanced understanding of genetic diversity in soybean resistance to various pathogens

== Selected Publications ==

1. "Biological Control Activities of Rice-Associated Bacillus sp. Strains against Sheath Blight and Bacterial Panicle Blight of Rice" (2016)<ref name=":1" />
2. "Natural Genetic Diversity in the Potato Resistance Gene RB Confers Suppression Avoidance from Phytophthora Effector IPI-O4" (2021)<ref>https://apsjournals.apsnet.org/doi/10.1094/MPMI-11-20-0313-R</ref>
3. "Screening of Wild Potatoes Identifies New Sources of Late Blight Resistance" (2021)<ref>https://apsjournals.apsnet.org/doi/10.1094/PDIS-06-20-1367-RE</ref>
