Gatersleben Lecture with Dr. Matthew J. Moscou

June 11, 2024 / 2 pm, Dr. Matthew Moscou from University of Minnesota will speak in frame of the Gatersleben Lecture Series. His lecture title is "Evolution of immunity in the grasses".

Abstract: The Poales order emerged during Early Cretaceous (100-125 Mya) period and rapidly expanded to represent over 7% of angiosperm diversity. The major field crops maize, wheat, sorghum, millet, barley, and rice belong to the grasses (Poaceae), a family within the Poales. Sequencing of these six Poaceae crops and other grass species uncovered large-scale conservation in gene content between species. During the evolution and divergence of the Poaceae from other species in the Poales, several gene families experienced expansion, contraction, and innovation. In previous work, we discovered a lineage-specific clade of plant immune receptors (nucleotide-binding, leucine-rich repeat proteins; NLRs) that harbor substantial diversity in integrated domains. Due to the limited number of sequenced species, we could not establish the emergence of this clade in the evolution of the grasses and the degree of intraspecific integrated domain diversity. In ongoing work, we have leveraged genomic and transcriptomic data from 124 Poales species including 334 accessions to bioinformatically characterize NLR diversity. We establish a timeline of emergence of the lineage-specific clade of NLRs with integrated domains and identify the diversity of integrated domains in grasses. These discoveries have uncovered several lineage-specific genetic innovations that are key virulence targets in grasses
