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...

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 4‐hydroxyphenylpyruvate dioxygenase‐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...

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

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.

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.
