Methods of producing pesticidal cotton cells, cotton plants and seeds by transformation with heterologous pesticidal lectin encoding nucleic acid sequences are disclosed.

Methods for producing pesticidal cotton plants expressing lectins

A transformed cotton plant. The transformed cotton plant comprises DNA derived from a source other than cotton plants, wherein the DNA, when transformed into the cotton plants, confers a phenotype not expressed inn a parent cotton.

Transformed cotton plants

Chimeric genes encoding lectins exhibiting pesticidal activity (for example, insecticidal and/or fungicidal activity) are disclosed which can be used to transform cotton to yield cotton cells, plants, and seeds in which the chimeric genes are expressed. Such transformed cotton cells are pesticidal when ingested by cotton pests.

Cotton cells, plants, and seeds genetically engineered to express insecticidal and fungicidal chitin binding proteins (lectins)

A transformed cotton plant. The transformed cotton plant comprises DNA derived from a source other than cotton plants, wherein the DNA, when transformed into the cotton plants, confers a phenotype not expressed in a parent cotton.

A method for producing transformed cotton plants. The method comprising providing cotton explants, incubating the cotton explant in the presence of a vector comprising a selectable marker to produce treated explants, growing the treated explants to produce callus and selecting transformed callus.

Transformation of cotton plants

A vector for transforming cotton. The vector comprising integration sequences for integrating into the genome of cotton plants, a promoter for promoting transcription in cotton plants, a DNA sequence encoding a selectable marker and a termination signal for terminating transcription in cotton plants.
