Abstract: The present disclosure relates, according to some embodiments, to pathogen resistant citrus compositions, organisms, systems, and methods. For example, a composition may comprise a peptide (e.g., a defensin peptide) and/or a nucleic acid (e.g., a defensin nucleic acid). A pathogen resistant citrus plant may comprise, in some embodiments, a defensin peptide and/or an expressable nucleic acid encoding a defensin peptide.

Abstract: The present disclosure relates, in some embodiments, to potato transformation compositions, systems, methods, microorganisms, and plants (e.g., one or more potato chipping varieties). In some embodiments, a method of transforming and/or transfecting a plant (e.g., ‘Atlantic’ potato) may comprise (a) growing an ‘Atlantic’ potato plant (e.g., from a tuber) for from about 3 weeks to about 4 weeks, (b) removing one or more leaf sections (e.g., each section from about 0.5 cm to about 1 cm in its longest dimension) from the plant, (c) cultivating the one or more sections on a callus induction medium comprising zeatin for about 2 days, and/or (d) contacting the one or more sections with Agrobacterium comprising the exogenous nucleic acids under conditions that permit transfer of the exogenous nucleic acid to the one or more sections to produce at least one transformed and/or transfected plant cell.
