Abstract: A plant support for centrifuging plants comprises at least first and second portions that are configurable in a closed configuration that defines an internal cavity adapted to radially support plants in a manner at least partially preventing the plants from deforming or changing orientation during centrifugation. The first and second portions are also configurable in an open configuration that allows the plants to be inserted between the at least first and second portions into what becomes the internal cavity from the side rather than axially. Another plant support comprises a plurality of plant support rods that are removably attached to a platform that holds the plant support rods perpendicular to the platform and parallel to each other during centrifugation. A method involves supporting a plant radially relative to the g-loading during centrifugation such that a treatment agent remains in contact with only a portion of the plant.

Abstract: This invention relates to compositions and methods for improving/enhancing yield traits by modifying cytokinin oxidase (CKX) levels in a plant. The invention further relates to plants produced using the methods and compositions of the invention.

Abstract: Provided are methods for increasing the efficiency of creating doubled haploid plants by increasing the number of chances of forming a double haploid seed through treatment of a monocot plant with a plant growth regulator. In certain embodiments, maize plants are produced that comprise multiple co-dominant ears. Also provided are plants comprising the potential to generate increased numbers of doubled haploid offspring.

Abstract: Provided herein are delivery methods of a plant treatment agent to a tissue of a plant, wherein the tissue is contacted with a plant treatment agent and delivery is aided by a centrifugal force applied to the plant. Disclosed herein is the discovery that drastic improvements in treatment delivery occur when plants are centrifuged after being contacted, submerged, unsubmerged, soaked, etc. in a solution containing a plant treatment agent. In one embodiment, haploid plants contacted with a colchicine solution are centrifuged to reveal improved chromosomal doubling rates as compared to control plants.
