We have posted our latest preprint. We explore how an endophytic fungus promotes plant growth and fitness under fluctuating nitrogen-limited conditions in both field and laboratory settings, in additively with bacteria attracted to its hyphae. We hope you enjoy it!

Promiscuous cytochrome P450s confer metabolic resistance to synthetic auxin herbicides in the weedy grass Echinochloa phyllopogon Auxinic herbicides are critically important tools for weed control in modern agriculture. Although resistant weed populations have been increasing in recent years, the underlying mechanisms remain lar...

Happy to share our latest preprint describing the mechanism of resistance to auxinic herbicides.

The evolution of separate sexes in waterhemp is associated with surprising chromosomal diversity and complexity Waterhemp has recently evolved separate male and female plants within a genus where most species have both sexes on one plant. This study reveals surprising chromosomal diversity and complexity associ...

OsDNR1 as a key regulator of rice resistance to 4โ€hydroxyphenylpyruvate dioxygenaseโ€inhibiting herbicides DULL NITROGEN RESPONSE 1 (OsDNR1) is a key gene in rice resistance to herbicides that target 4-hydroxyphenylpyruvate dioxygenase, which are phytotoxic due to their effects on homogentisic acid levels...

Knockout of OsDNR1 enhances rice tolerance to HPPD inhibitors

A rearranged Amaranthus palmeri extrachromosomal circular DNA confers resistance to glyphosate and glufosinate Abstract. Some herbicide-resistant weeds become resistant by generating additional copies of specific loci. For example, amplification of the locus encodin

Super proud of our new paper in @theplantcell.bsky.social. check it out if you like genomics.

New Article: "Chromosomal inversion at the DG1 promoter drives double-grain spikelets and enhances grain yield in sorghum" rdcu.be/edwuw

36kb inversion in DG1 promoter increases DG1 expression, inducing double-grain spikelets by restoring fertility to the lower floret.

Jimbocho station in Tokyo.
Jimbocho town is known for books, so the walls feature a motif of stacked books.

I have joined with the Weed Genomics Consortium to annotate P450s from approximately 50 weed genomes. So far I have named the P450s from 31 weed genomes. papers are in the pipeline.
