UNLABELLED PREMISE OF THE STUDY Single nucleotide polymorphism (SNP) markers based on Competitive Allele-Specific PCR (KASPar) were developed from sequences of three Citrus species. Their transferability was tested in 63 Citrus genotypes and 19 relative genera of the subfamily Aurantioideae to estimate the potential of SNP markers, selected from a limited intrageneric discovery panel, for on...

On the basis of monitoring the prevention of accumulation of lipid droplets in mouse 3T3-L1 preadipocyte cells and inhibition of the proliferation of human colon cancer HT-29 cells, effective anti-corpulence and anticancer compounds were isolated from the peel of Citrus fruits. These bioactive components were identified as polymethoxyflavones and coumarin derivatives by spectroscopic analyses. ...

Of the many nematode species that parasitize citrus, Tylenchulus semipenetrans is the most important on a worldwide basis. Management of the citrus nematode remains problematic as no one tactic gives adequate control of the nematode. An overall management strategy must include such components as site selection, use of non-infected nursery stock, use of at lease one post-plant nematode control t...

The encyrtid wasp, Psyllaphycus diaphorinae Hayat, was reared from nymphs of Asian citrus psyllid, Diaphorina citri Kuwayama, on Citrus spp. and Murraya sp. collected in Faisalabad, Punjab, Pakistan. This discovery is a new host record for P. diaphorinae, which previously had been known only from India from a different, congeneric host. Taxonomic notes on this little known species are given, il...

In this study, we identified and compared nucleotide-binding site (NBS) domain-containing genes from three Citrus genomes (C. clementina, C. sinensis from USA and C. sinensis from China). Phylogenetic analysis of all Citrus NBS genes across these three genomes revealed that there are three approximately evenly numbered groups: one group contains the Toll-Interleukin receptor (TIR) domain and tw...

Yuzu (Citrus junos Sieb. Ex Tanaka) is one of the most important Citrus species in China, Japan, and Korea. assumed to be a natural hybrid. However, concrete evidence supporting its hybrid origin has not been reported yet. To identify putative maternal species, nucleotide sequences five hypervariable regions covering 17,531 bp citrus chloroplast genomes were obtained from yuzu. A phylogenetic t...

Citrus greening (huanglongbing) is the most destructive disease of citrus worldwide. It is spread by citrus psyllids and is associated with phloem-limited bacteria of three species of α-Proteobacteria, namely, 'Candidatus Liberibacter asiaticus', 'Ca. L. americanus', and 'Ca. L. africanus'. Recent findings suggested that some Japanese strains lack the bacteriophage-type DNA polymerase region (D...

Citrus species grown in Japan are affected by several viruses and viroids, including satsuma dwarf virus, citrus vein enation exocortis viroid, other viroids. Recently, a comprehensive review was made on the occurrence, history, research of following three major Japan: tatter leaf virus (apple stem grooving virus), tristeza (Iwanami 2022). As sequel, this study reviews development viroids as we...

Fourteen mite species of plant-associated mites of the suborder Prostigmata are reported from the Dominican Republic. Four of these refer to new findings for the country, including Petrobia (Tetranychina) hispaniola n. sp. Sánchez & Flechtmann, described from specimens collected from leaves of Citrus sp. (Rutaceae) and Rosa sp. (Rosaceae). A key for the separation of the world species of Petrob...
