Root-knot nematodes produce functional mimics of tyrosine-sulfated plant peptides

This study identifies nematode-produced sulfated peptides similar to bacterial virulence factors that promote plant root growth and nematode parasitism.

An open source plant kinase chemogenomics set

The paper presents a plant kinase chemogenomics set, identifying compounds that affect root development in Arabidopsis and rice, with implications for understanding plant kinase function.

Sulfotyrosine, an interaction specificity determinant for extracellular protein-protein interactions

This paper identifies sulfotyrosine (sTyr) as a key determinant of extracellular protein-protein interaction specificity, highlighting its roles in hormone-receptor binding, HIV entry, chemokine signaling, and blood clotting.

Mechanism and function of root circumnutation

The paper identifies molecular regulators of root circumnutation and demonstrates its functional role in root exploration and seedling establishment.

Sulfated RaxX, which represents an unclassified group of ribosomally synthesized post-translationally modified peptides, binds a host immune receptor

The paper identifies RaxX as a sulfated RiPP that binds the rice immune receptor XA21, revealing its role in bacterial immune activation.

A microbially derived tyrosine sulfated peptide mimics a plant peptide hormone

The paper shows that a synthetic sulfated RaxX peptide mimics plant PSY peptides to promote root growth and that XA21 recognizes microbial RaxX to trigger immunity.

The Sequence of 1504 Mutants in the Model Rice Variety Kitaake Facilitates Rapid Functional Genomic Studies

The paper sequenced 1,504 mutant lines in the rice variety Kitaake and established a database to enable rapid functional genomic studies.
