The present disclosure relates to a single stranded RNA vector suitable for introducing a therapeutic agent, such as a peptide, a protein or a small RNA, into a host plant. The vector does not encode for any movement protein or coat protein, but is capable of capable of systemic and phloem-limited movement and replication within the host plant.

A new and distinct mandarin variety of Citrus deliciosa Ten. named ‘SIGAL’, particularly characterized by easy-peeling, late ripening, high quality flavor, flattened fruit shape at stalk end, medium size fruit, dark orange skin color and lacking seed.

The present disclosure concerns methods of using novel bacterial strains of 0617-T307, 0917-T305, 0917-T306, 0917-T307, 0118-T319, 0318-T327, and 0418-T328, the cell broth and novel metabolites produced from the bacterial strains, to inhibit the growth of a variety of microbial species for bacterial pathogens that cause citrus Huanglongbing (citrus greening disease), Zebra chip (ZC) disease of potato, tomato, and other plants of the family Solanaceae and plants of the family Apiaceae and Umbelliferae. The methods include use of novel, potent antimicrobial metabolites produced from the strains corresponding to a Pseudomonas bacterial metabolite as Formula (I):

A composite orange tree having a fruiting cultivar scion grafted to a citrus-greening resistant, or a salinity-resistant rootstock, or a rootstock having both citrus-greening and salinity resistance, is described herein, as are methods of growing such a composite orange tree.

A new and distinct cultivar of Citrus Sinensis plant, “Noah”, is disclosed that is characterized by its resistance or tolerance to Citrus greening, also known as Huanglongbing.

A new and distinct sweet orange clone ‘OLL-20’ has been developed from an unstable sweet orange selection designated as ‘OLL’, using tissue culture techniques. Undeveloped ovules from fruit of selection ‘OLL’ were cultured in vitro to generate an embryogenic callus, from which multiple independent clones were regenerated via somatic embryogenesis. Regenerated plantlets (somaclones) were grafted to UFR rootstocks and grown in the field for evaluation.

A new and distinct cultivar of Citrus Sinensis plant, “Noah”, is disclosed that is characterized by its resistance or tolerance to citrus greening, also known as Huanglongbing.

The present disclosure relates to ‘Jedae mandarin’, a new citrus variety of early-ripening satsuma mandarin. The branch buds of C. unshiu Marc. cv. Miyagawa-wase, an early-maturing satsuma mandarin, underwent gamma irradiation and subsequent grafting for asexual propagation. As a result, the ‘Jedae mandarin’, a novel variety of citrus plant, showed uneven peels of fruits and changes in flavonoid content, compared to C. unshiu Marc. cv. Miyagawa-wase, although it exhibited characteristics very similar to those of C. unshiu Marc. cv. Miyagawa-wase in terms of blooming, fruit-bearing, sugar content, acidity, etc. Thus, ‘Jedae mandarin’ may be used as a new variety with high economic value.

A new and distinct variety of mandarin tree named ‘11C017R’, particularly selected for non-acidic flavour profiles and distinguished by the smooth skin texture, cleanness of peeling and high Brix levels, is disclosed.

The disclosure relates to novel disarmed Agrobacterium tumefaciens strains, uses of these disarmed Agrobacterium strains, and kits comprising such disarmed Agrobacterium strains. The disarmed Agrobacterium strains are effective for the transformation of plant, fungal, or algae cells. The Agrobacterium strains are very effective for the transformation of citrus plant cells.
