Abstract:
The Zea mays c.v. B73 Ubiquitin-1 (Z. mays c.v. B73 Ubi-1) promoter drives high levels of constitutive transgene expression in plants. Repeated use of the same Z. mays c.v. B73 Ubi-1 promoter in multi-gene constructs may also lead to gene silencing, thereby making transgenic products less efficacious. Provided are gene regulatory promoter elements, constructs, and methods for expressing a transgene in plant cells and/or plant tissues using gene regulatory elements from the Ubi-1 promoter of a different Z. mays genotype, Z. mays c.v. B104.
Abstract:
Provided are constructs and methods for expressing a transgene in plant cells and/or plant tissues using Zea mays metallothionein-like gene regulatory elements.

Abstract:
The present disclosure provides novel compositions and methods for the production and use of Agrobacterium tumefaciens strains (for example LBA4404) that are deficient in RecA activity relative to the parent strain. Combinations with other gene-deficient-strains of Agrobacterium tumefaciens are also disclosed. Specifically, two exemplary s recA minus strains, UIA777 where chloramphenicol resistant gene disrupting the recA gene and UIA770 where kanamycin resistant gene disrupting the recA gene are provided.
