This disclosure relates to plants having a modified F5H gene which confers the trait of reduced wound-induced surface discoloration. The disclosure further relates to all progeny, seed, and plant parts of said plant. Furthermore, the disclosure relates to a propagation material suitable for producing said plants, and to methods for selecting and producing said plants.

The present technology provides a nanoparticle that includes a silica network comprising crosslinked polysiloxanes, wherein the crosslinks comprise disulfide linkages, and the nanoparticle has a surface bearing charged functional groups and a surface potential of either less than −30 mV or greater than +30 mV, and wherein the nanoparticle has an average diameter of 20 nm to 60 n. The nanoparticles may be used to efficiently deliver biomolecules to plant cells, including polynucleic acids, proteins and complexes thereof (e.g., Cas9 RNP).

The present invention relates to a method for introducing a polynucleotide into non-adhesively growing plant cells, comprising the following steps: providing a solid support having immobilized thereto the polynucleotide in dry state; contacting the plant cells with the polynucleotide on the solid support so as to obtain transformed plant cells; and optionally washing the plant cells.

The invention describes a device (10) for dispensing microbubbles (30) for cell sonoporation, comprising: a tube configured to receive a vial (20) containing a solution (26) of microbubbles (30), at least two catheters (11, 12) arranged inside the tube and opening into the vial (20) when the latter is received by the tube,
wherein, when the first catheter (11) is connected to a first air injection source, air can be injected into the vial (20) via the first catheter so as to generate an overpressure therein, the microbubbles (30) contained in the vial (20) entering the second catheter (12) and moving toward its second end (122). The invention also relates to a sonoporation device, a sonoporation process and a computer program product.

The invention provides novel methods and compositions for introduction, transfer or delivery of one or more biomolecules into wounded recipient plant cell(s). Methods for production of a wounded recipient cell culture and the creation of one or more mutations, edits, transgenic insertions, or other genetic changes in the recipient cell(s) are also provided. Product cells produced by such methods, and resulting cells and regenerated plants, plant parts, and progeny plants are further provided. Molecular and genetic analyses, analysis of phenotypes and traits, and use of screenable and selection markers, are also provided to confirm transfer of the biomolecule in to the recipient cell(s) and generation of the mutation, edit, transgenic insertion, or other genetic change in the recipient cell(s), and/or progeny thereof, and in plants or plant parts developed or regenerated from the foregoing.

A method of modifying the genome of an organism, wherein the modification method includes modifying the genome of the organism by using in a cell of the organism a protein having an optimal temperature for double-stranded DNA breakage activity in an ordinary temperature region.

In one aspect, a composition can include an organelle, and a nanoparticle having a zeta potential of less than −10 mV or greater than 10 mV contained within the organelle. In a preferred embodiment, the organelle can be a chloroplast and the nanoparticle can be a single-walled carbon nanotube associated with a strongly anionic or strongly cationic polymer.

The invention provides for Sorghum plants and plant parts developed through tissue culture, gene editing, or other methods of mutagenesis in which the plant or plant parts have increased tolerance to one or more acetyl-CoA carboxylase (ACC) herbicides at levels that would normally inhibit the growth of wild-type Sorghum plants. In this context, the Sorghum plant may be tolerant to any herbicide capable of inhibiting acetyl-CoA carboxylase enzyme activity. The present invention allows for the screening of ACC herbicide tolerant hybrids with markers or application of ACC inhibiting herbicides, and for the removal of unwanted vegetation with application of ACC inhibiting herbicides from seed and grain production fields.

Plant cell cultures as well as related methods, systems, and compositions for increasing the frequency and efficiency of plant genome editing are provided. Various plant cell growth conditions and/or treatments where such increases in gene editing frequencies are obtained are disclosed.

The disclosure is directed to nanoparticles, compositions comprising nanoparticles, and methods of using the nanoparticles and compositions to introduce genetic material into a host cell, and in particular, a plant cell nucleus, to cause transformation of the host cell through the expression of genes on the introduced genetic material.
