A protein intermediary in the interaction of a hormone with the genome (1969)

Matthysse, Ann G., Phillips, Cornell

The increased rate of RNA synthesis by target cells caused by the plant hormone auxin has been studied as an example of hormonal regulation of transcription. The hormone does not interact directly...

The Effect of the Agrobacterium tumefaciens attR Mutation on Attachment and Root Colonization Differs between Legumes and Other Dicots

Matthysse, Ann G., McMahan, Susan

Infections of wound sites on dicot plants by Agrobacterium tumefaciens result in the formation of crown gall tumors. An early step in tumor formation is bacterial attachment to the plant cells. AttR...

Root Colonization by Agrobacterium tumefaciens Is Reduced in cel, attB, attD, and attR Mutants

Matthysse, Ann G., McMahan, Susan

Root colonization by Agrobacterium tumefaciens was measured by using tomato and Arabidopsis thaliana roots dipped in a bacterial suspension and planted in soil. Wild-type bacteria showed extensive...

Identification of Arabidopsis rat Mutants

Zhu, Yanmin, Nam, Jaesung, Humara, Jaime M., Mysore, Kirankumar S., Lee, Lan-Ying, Cao, Hongbin, ...

Limited knowledge currently exists regarding the roles of plant genes and proteins in the Agrobacterium tumefaciens-mediated transformation process. To understand the host contribution to...

Effect of Plasmid pSa and of Auxin on Attachment of Agrobacterium tumefaciens to Carrot Cells

Matthysse, Ann G.

When the plasmid pSa is introduced into Agrobacterium tumefaciens, its presence results in the suppression of bacterial virulence. A. tumefaciens(pSa) cells are virulent on Bryophyllum diagremontiana...

A PROTEIN INTERMEDIARY IN THE INTERACTION OF A HORMONE WITH THE GENOME*

Matthysse, Ann G., Phillips, Cornell

The increased rate of RNA synthesis by target cells caused by the plant hormone auxin has been studied as an example of hormonal regulation of transcription. The hormone does not interact directly...

Agrobacterium-Mediated Root Transformation Is Inhibited by Mutation of an Arabidopsis Cellulose Synthase-Like Gene1

Zhu, Yanmin, Nam, Jaesung, Carpita, Nicholas C., Matthysse, Ann G., Gelvin, Stanton B.

Agrobacterium-mediated plant genetic transformation involves a complex interaction between the bacterium and the host plant. Relatively little is known about the role plant genes and proteins play in...

A functional cellulose synthase from ascidian epidermis

Matthysse, Ann G., Deschet, Karine, Williams, Melanie, Marry, Mazz, White, Alan R., Smith, William C.

Among animals, urochordates (e.g., ascidians) are unique in their ability to biosynthesize cellulose. In ascidians cellulose is synthesized in the epidermis and incorporated into a protective coat...

Involvement of Carrot Cell Surface Proteins in Attachment of Agrobacterium tumefaciens1

Gurlitz, Robin H. G., Lamb, Patricia W., Matthysse, Ann G.

The initial step in tumor formation by Agrobacterium tumefaciens is the site-specific attachment of the bacteria to plant cells. A similar attachment to plant tissue culture cells has been observed....

Differential Binding of Escherichia coli O157:H7 to Alfalfa, Human Epithelial Cells, and Plastic Is Mediated by a Variety of Surface Structures

Torres, Alfredo G., Jeter, Cecelia, Langley, William, Matthysse, Ann G.

Escherichia coli O157:H7 carried on plant surfaces, including alfalfa sprouts, has been implicated in food poisoning and outbreaks of disease in the United States. Adhesion to cell surfaces is a key...

Polysaccharides Cellulose, Poly-β-1,6-N-Acetyl-d-Glucosamine, and Colanic Acid Are Required for Optimal Binding of Escherichia coli O157:H7 Strains to Alfalfa Sprouts and K-12 Strains to Plastic but Not for Binding to Epithelial Cells▿

Matthysse, Ann G., Deora, Rajendar, Mishra, Meenu, Torres, Alfredo G.

When Escherichia coli O157:H7 bacteria are added to alfalfa sprouts growing in water, the bacteria bind tightly to the sprouts. In contrast, laboratory K-12 strains of E. coli do not bind to sprouts...
