  • Patent number: 12082544
    Abstract: Provided is a method for producing a banana plant with tolerance or resistance to Fusarium oxysporum Cubensis TR4 and such plants. The method includes (a) exposing one or more banana meristems, in one or more propagating cycles, to a medium including a demethylating agent (in vitro mutagenesis) to thereby provide one or more banana meristems exhibiting expression and thereby amplification of retrotransposable elements in their plant genome as determined by Southern blot hybridization analysis, and (b) rooting the meristems that exhibited the amplification and regenerating therefrom one or more regenerated banana plants, at least one of the regenerated banana plants having tolerance or resistance to Fusarium oxysporum Cubensis TR4.

  • Publication number: 20220201910
    Abstract: ‘RSV’ is a mutant of ‘Valery’ selected on the merits of being a shorter cultivar while simultaneously being a more productive cultivar for the grower. ‘RSV’ shows the following characteristics: More productive due to an additional 2 marketable hands per bunch, Longer fingers, And a higher number of fingers in a bunch. The most important characteristic of ‘RSV’ is its lower stature that will contribute to more efficient agronomic practices such as; Fruit harvesting, bunch bagging, and better wind tolerance.

  • Patent number: 8716554
    Abstract: The present invention relates to transgenic plants resistant to parasites that their normal life cycle includes feeding on the plant cytoplasm, including insects, nematodes and fungi, wherein the plants are engineered to produce small interfering RNAs (siRNAs) capable of silencing a parasite specific gene. Particularly the parasite gene is a stage-specific gene, more particularly a gene involved in essential, early developmental stages of the parasite in or on the plant.

  • Patent number: 8097773
    Abstract: The invention provides a process for selecting banana clones that are characterized by increased bunch weight and by increased total fruit yield, which process is based on somaclonal variation and comprises the steps of initiating tissue cultures from apical meristem explants, and propagating and rooting the same; hardening, potting, and growing in vivo, plants propagated in the previous step; forming a mat from a cluster of plants grown in the previous step originating from the same clone; planting the mats from the previous step in a field, and growing them under conditions of abiotic stress, the conditions including the growth of the mats in an area wherein the average winter night temperature is below 10° C.

  • Patent number: 7897840
    Abstract: The present invention provides transgenic plants transformed with exogenous nucleic acid encoding a Dunaliella salt-inducible or salt-responsive protein selected from the group consisting of eukaryotic initiation factor 3 (eIF3) subunit, NADPH dependent quinone reductase (QOR), aldo-keto reductase (AKR), bifunctional aspartate kinase-homoserine reductase (AK-HSD) and mitochondrial import membrane translocase subunit (TIM9), or a fragment, homolog or variant thereof. The transgenic plants have increased tolerance to salt as compared to corresponding non-transgenic plants.

  • Publication number: 20090044290
    Abstract: The present invention provides transgenic plants transformed with exogenous nucleic acid encoding a Dunaliella plasma membrane (PM)-ATPase. The transgenic plant has increased tolerance to salt as compared to a corresponding non-transgenic plant. The present invention also provides nucleic acids encoding a chimeric PM-ATPase, which comprise a first portion encoding a plant PM-ATPase or a fragment thereof, and a second portion encoding a Dunaliella PM-ATPase or a fragment thereof. The present invention also discloses a method of producing a transgenic plant having an increased tolerance to salt as compared to a corresponding non-transgenic plant, a method of modifying a plant capacity to survive salt shock, and a method of modifying plant recovery after exposure to salt stress, by introducing into one or more cells of a plant an exogenous nucleic acid encoding a Dunaliella PM-ATPase.
