BACKGROUND In recent years, the development of structural genomics has generated a growing interest in obtaining haploid plants. The use of homozygous lines presents a significant advantage for the accomplishment of sequencing projects. Commercial citrus species are characterized by high heterozygosity, making it difficult to assemble large genome(More)
The long juvenile period of citrus trees (often more than 6 years) has hindered genetic improvement by traditional breeding methods and genetic studies. In this work, we have developed a biotechnology tool to promote transition from the vegetative to the reproductive phase in juvenile citrus plants by expression of the Arabidopsis thaliana or citrus(More)
Damage caused by Citrus psorosis virus (CPsV) could be avoided obtaining resistant cultivars by breeding, but the sensitivity of most citrus hosts to CPsV is unknown. To find potential sources of resistance we inoculated 63 cultivars and hybrids of Citrus and related genera [Citrus (36), Microcitrus (5), Fortunella (6), Eremocitrus (1), Pleiospermium (1),(More)
