Abstract: The present invention provides a novel method for the transduction and/or transfection of plant cells. Cell-penetrating peptides (CPPs) have been successfully employed as nanocarriers to deliver proteins and oligonucleotides to single plant cell microspores as well as multi-cellular zygotic embryos. The efficiency of CPP internalization and further delivery of a macromolecular cargo comprising a protein and/or an oligonucleotide can be enhanced by permeabilization of the zygotic embryos.
Abstract: The invention provides methods and compositions for increasing the efficiency of genetic transformation of host cells, including plant cells, and other eukaryotic cells, by reducing the expression of a polypeptide active in a pathway, such as the NHEJ pathway, for repairing damage to the cellular genome. In certain embodiments, the polypeptide is active in repairing double strand breaks (DSB's) of a cellular genome, and may include XRCC4, KU70, KU80, the DNA-activated Protein Kinase (DNA-Pkcs), and ATM. Methods for enhancing the resistance of plant cells to Crown Gall disease are also provided. In another aspect, genetic regulatory elements are provided, including an XRCC4 promoter.

Abstract: Compositions and methods for transiently expressing proteins in a plant are provided. The compositions comprise plants, seeds, plant tissues, and plant parts expressing a protein, wherein the protein is expressed transiently and the transient expression of the protein can be used as a predictive model of how said protein will be expressed in stable transgenic plants in regards to qualitative and quantitative data. The predictive model may be used but is not limited to: promoter evaluation, evaluation of expression cassette construction for best performance (e.g. addition of enhancers or gene silencing suppressors), evaluation of best ways to express heterologous genes (e.g. point mutations, targeting), fast evaluation of endogenous gene knockout, evaluation of protein expression levels, cellular targeting, tissue targeting, transcriptional enhancers, translational enhancer protein toxicity and metabolic profiling. Further provided are methods of use.
Abstract: A genome shuffling method for autogamous plants, including producing individuals having the following three traits in a tight coupling linkage by a gene engineering technique selected from a transgenic technique and a gene targeting technique: 1) dominant male sterility, 2) chemical tolerance and 3) lethality inducible by activating an inducible promoter, selecting, from progeny of the individuals, male-sterile individuals by means of the chemical tolerance described in 2) and male-fertile individuals by means of the lethality described in 3), arranging the male-sterile individuals and the male-fertile individuals close together in flowering periods thereof, so that the male-sterile individuals are crossed with the male-fertile individuals, harvesting seeds from the male-sterile individuals, and repeating outcrossing using the seeds from generation to generation.
Abstract: In various embodiments, methods described herein comprise the use of water-soluble cationic fullerene derivatives for improving plant genetic transformation. Cationic Fullerene derivatives of the invention possess DNA binding and compaction activity and provide a new method to deliver DNA into plant cells for plant transformation. Water-soluble fullerene derivatives of the invention with anionic or non-polar substituents possess antioxidant (free radical scavenging) activity, provide improved yields and efficiency of plant transformation methods such as biolistic, Agrobacterium tumefaciens, or electroporation methods by limiting cellular damage and resulting cell death leading to higher yields of viable transformed cells in the process.

Abstract: It is intended to provide a polynucleotide comprising a viral base sequence, the viral base sequence containing: a first base sequence encoding a viral replication protein, and a second base sequence encoding a viral movement protein, the second base sequence being located downstream of the first base sequence and having a linking site for linking with an exogenous base sequence encoding a polypeptide to be expressed, the linking site being located downstream of the second base sequence, the second base sequence being obtained by modifying with a base sequence in a native sequence derived from a virus by insertion, substitution, or addition. By using this, a vector containing a viral base sequence is constructed, and a protein is efficiently produced without worsening growth of a host cell containing the vector.

Abstract: This disclosure relates to a mutant Agrobacterium tumefaciens that is functionally deleted for the atu1060 gene that codes for the cyclic di-GMP synthase Atu1060, as well as methods for its use in transforming plants with desired transgenes. Such bacteria are more virulent than currently used strains of A. tumefaciens, and thus can be used to transform a wider variety of plants, such as plants that are traditionally recalcitrant to such transformation.

Abstract: A method of introducing a molecule of interest into a plant cell having a cell wall includes interacting a gamma-zein peptide with a molecule of interest to form a gamma-zein linked structure. The gamma-zein linked structure is then placed in contact with the plant cell having a cell wall, and allowing uptake of the gamma-zein linked structure into the plant cell. Alternatively, a gene of interest can be expressed in a plant cell having an intact cell wall by interacting a gamma-zein peptide with the gene of interest to form a gamma-zein linked gene structure, allowing uptake of the gamma-zein linked gene structure into the plant cell, and expressing the gene of interest in the plant cell and its progeny.
