A highly efficient Cre-mediated deletion system, offering a good alternative for producing marker-free transgenic plants that will relieve public concerns regarding GMOs, was first developed in citrus. The presence of marker genes in genetically modified crops raises public concerns regarding their safety. The removal of marker genes can prevent the risk of(More)
To improve the resistance of citrus to canker disease caused by Xanthomonas axonopodis pv. citri (Xac), it is important to identify gene promoters that are specifically induced by pathogen infection. Here, we evaluated the functionality of PPP1 and hsr203J (Nicotiana tabacum L.) and gst1 (potato) pathogen-inducible promoters to drive expression of the(More)
Marker-free transgenic plants alleviate concerns regarding the biosafety of genetically modified organisms and promote their commercialization. In this study, a transformation vector pLI35SAAT, harboring a Cre/loxP-mediated recombination system combined with the isopentenyl transferase (ipt) selectable marker gene and an anti-bacterial peptide gene AATCB,(More)
Expression of synthesized cecropin B genes in the citrus phloem, where Candidatus Liberibacter asiaticus resides, significantly decreased host susceptibility to Huanglongbing. Huanglongbing (HLB), associated with Candidatus Liberibacter asiaticus bacteria, is the most destructive disease of citrus worldwide. All of the commercial sweet orange cultivars lack(More)
