The present invention relates to materials and methods for creating and maintaining a cereal plant line for the production of a hybrid cereal plant, that include for example, and not limitation, using the BLue Aleurone (BLA) system.

The present invention relates to a composition comprising methyl jasmonate and a polysiloxane polyether for increasing the content of glucosinolates in adult plants of the genus Brassica, for example, broccoli. By means of foliar application of the composition on adult plants having a developed cuticle, a significant increase is achieved in the concentrations of glucosinolates (mainly glucoraphanin and neoglucobrassicin), in the floret of the plants, without degrading the organoleptic properties thereof.

A neutron ray irradiation target apparatus 100 of the present invention is used to irradiate irradiation targets (seeds, etc.) with a neutron ray generated by a neutron ray irradiation apparatus. The neutron ray irradiation target apparatus 100 has a holding means 70 for holding the irradiation targets. The holding means 70 holds at least one closed container 30 which can accommodate the irradiation targets 20 stacked randomly and three-dimensionally. In the case where the irradiation targets are stacked three-dimensionally and accommodated in the closed container, the irradiation targets overlapping each other are irradiated with the neutron ray in a chain reaction fashion. The neutron ray irradiation target apparatus 100 can be used in a method for irradiating a large amount of irradiation targets (seeds of crops, etc.) with a neutron ray, while reducing a required time, thereby efficiently inducing mutations in the irradiation targets.

The present invention provides high-throughput methods capable of screening compounds for herbicidal activity or plant growth regulating activity and further allows for the prediction of the mode of action of herbicidal compounds or plant growth regulators. The methods provided herein also facilitate the identification of mutation/s responsible for resistance to herbicides in plants and the identification of the herbicide target. The methods further provide for the identification of mutation/s responsible for plant growth regulation and the identification of the plant growth regulator target.

A method to transforming a plant includes coating a microparticle having a diameter of 0.3 to 0.9 μm with at least one type of nucleic acid, bombarding a shoot apex of the plant with the coated microparticle using a gene gun, growing the shoot apex bombarded with the coated microparticle to obtain a plant body, and selecting a transformed plant body from the plant body. The shoot apex is selected from the group consisting of a shoot apex of an embryo of a fully mature seed, a shoot apex of a young bud of a tuber, and a shoot apex of a terminal bud or a lateral bud.

The current disclosure relates to methods and compositions for improving plant varieties through plant breeding and plant genetics. For instance, the disclosure concerns increasing the recombination frequency of a heterozygous trait genetically linked to a second trait within plants. Further, the disclosure concerns breaking the genetic linkage between a first allele and a second allele.

The present invention relates to a method for conducting high-throughput and directed mutagenesis for sugarcane resistance to glyphosate by plasma. The method is as follows: sugarcane embryonic calli are irradiated by a plasma instrument under a sterile condition for mutagenesis, wherein the mutagenesis power is 140˜200 W, the discharging distance is 35˜45 mm, the mutagenesis time is 110˜140 s and the protective gas is nitrogen; buffering culture, moderate/high concentration of glyphosate stress screening, differentiation into seedlings, glyphosate stress screening of bottle seedlings and stress screening via spraying glyphosate on the leave surfaces of potted plants are conducted for the treated calli. The present invention has the advantages of safe operation, simplicity, practicability, high handling capacity, low contamination, and due to implementation of directed stress screening, high screening efficiency, decreased subsequent screening workload and visual identification of resistant mutant strains.
