Citrus glauca CRC3463 genome v1

TaxonomyCitrus glauca (Lindl.) Burkill 

Synonyms: Eremocitrus glauca (Lindl.) Swingle

Cultivar: 'Australian desert lime'  

Accession IDs:  IVNO 6206; CRC 3463PI 539717

The sample was collected from a single tree (inventory identifier IVNO 6206, planted in 1983) in the Givaudan Citrus Variety Collection, University of California Riverside (UCR). The accession is identified as CRC 3463 in the UCR system and PI 539717 in the USDA National Plant Germplasm System (NPGS).   Seeds from a related source (Eremocitrus glauca hybrid (Lindl.) Swingle, CRC 4105) were propagated and used for testing for field resistance/tolerance against citrus Huanglongbing (HLB) disease in an HLB endemic region of Florida, USA and found to be highly tolerant to the disease (Ramadugu et al., 2016). In subsequent experiments, C. glauca (CRC 3463) was also found to be highly tolerant to HLB (unpublished). A description of C. glauca is available here.  Propagative and genetic material from this accession is available from the USDA National Clonal Germplasm Repository for Citrus and Dates, Riverside, California subject to phytosanitary regulations. Note: this accession has not been sanitized.

Functional Analysis

Functional annotation for the Citrus glauca CRC3463 genome v1.0 are available for download below. The Citrus glauca CRC3463 genome v1.0 proteins were analyzed using InterProScan in order to assign InterPro domains and Gene Ontology (GO) terms. Pathways analysis was performed using the KEGG Automatic Annotation Server (KAAS).

Homology of the Citrus glauca CRC3463 genome v1.0 proteins was determined by pairwise sequence comparison using the blastp algorithm against various protein databases. An expectation value cutoff less than 1e-6  for the Arabidoposis proteins (Araport11, 2022-09), UniProtKB/SwissProt (Release 2023-07), and UniProtKB/TrEMBL (Release 2023-07) databases. The best hit reports are available for download in Excel format.
