  • Publication number: 20240398897
    Abstract: Aspergillus flavus is an opportunistic, saprophytic fungus that infects maize and other fatty acid-rich food and feed crops and produces toxic and carcinogenic secondary metabolites known as aflatoxins. In vitro studies showed a five-fold increase in antifungal activity of AGM182 (vs. tachyplesin1) against A. flavus. Transgenic maize plants expressing AGM182 under maize Ubiquitin-1 promoter were produced through Agrobacterium-mediated transformation. PCR products confirmed integration of the AGM182 gene, while RT-PCR of maize RNA confirmed the presence of AGM182 transcripts. Maize kernel screening assay using a highly aflatoxigenic A. flavus strain (AF70) showed up to 72% reduction in fungal growth in the transgenic AGM182 seeds compared to isogenic negative control seeds.

  • Patent number: 5859321
    Abstract: A somaclonal variant cotton plant. The somaclonal cotton plant is produced by a method comprising providing a cotton explant, culturing the explant in a callus growth medium supplemented with glucose as a primary carbon source until secretion of phenolic compounds has ceased and undifferentiated callus is formed from the explant, culturing the undifferentiated callus in callus growth medium supplemented with sucrose as a primary carbon source until embryogenic callus is formed from the undifferentiated callus, transferring the embryogenic callus to a plant germination medium, culturing the embryogenic callus on the plant germination medium until a plantlet is formed from the embryogenic callus, transferring the plantlets to soil, growing the plantlets to produce seeds from self pollination, collecting the seeds, planting the seeds, growing the seeds under conditions to select for a desired characteristic and collecting the plants with the desired characteristics.
