The citrus greening disease (also called huanglongbing) has devastated the Florida citrus industry, and is now in CA and TX. Fruit from infected trees is safe to eat, but production is reduced so much that citrus may cease to be inexpensive and broadly available. If you are a citrus lover you should know that massive research efforts, including this project, are underway to keep citrus affordable and plentiful. See impact on US production.. Citrus Greening Solutions is a USDA NIFA project. Longitudinal Transcriptomic, Proteomic, and Metabolomic Analysis of Citrus limon Response to Graft Inoculation by Candidatus Liberibacter asiaticusThe most dramatic differences between the transcriptome and proteome of CLas-infected and control plants were observed at 10 wpg, including coordinated increases in transcripts and proteins of citrus orthologs of known plant defense genes. This integrated approach to quantifying plant molecular changes in leaves of CLas-infected plants supports the development of diagnostic technology for presymptomatic or early disease detection as part of efforts to control the spread of HLB into uninfected citrus groves.Updates to the functional anatomy of the male psyllid reproductive systemThe functional anatomy of the male psyllid reproductive system was recently updated. This revision uses modern tools to elucidate the system with high resolution so that molecular researchers can have a reference to cross-correlate their findings.Improved Diaphorina citri alimentary canal animationThis version reviews the first version of the alimentary canal and adds VolumeScope footage at a high level of resolution using modern imaging technology. The output contains 3D tomographic reconstruction of TEM ultrasections.Public service message to report HLB to CDFAOur colleagues in UC Davis have created this video about citrus greening disease (Huanglongbing or HLB) and how Californians can band together to prevent the spread and the end of fresh citrus for us all. Please report HLB to California Department of Food and Agriculture at 1-800-491-1899.Manual curation of Citrus genesGene models in C. sinensis and C. clementina can now be curated in the Apollo annotation tool. Please request access using the contact form. You can find more information about resources on the C. sinensis and C. clementina genome pages.Citrus added to VIGS toolCitrus genomes are now available in the VIGS tool to design virus induced gene silencing experiments on C. sinensis and C. clementina. More details about the tool are available in the publication.

The gut cells of the Asian citrus psyllid nymphs do not respond the same way to infection by the Huanglongbing bacterial pathogen as adult guts. This was unexpected. Scientists found a surprising visual difference between how nymph and adult guts of the Asian citrus psyllid (Diaphorina citri) respond to infection by "Ca. Liberibacter asiaticus," the causative bacterial agent of Huanglongbing (HLB), or Citrus greening disease. MoreGuts of Asian citrus psyllid adults change on a molecular level when feeding on plants infected with the citrus greening bacteriumKruse and her colleagues were interested in how CLas interacts with the gut to cross into the blood and be transmitted, and if the presence of CLas causes changes in the cells of the gut. To find out, researchers at the Boyce Thompson Institute and Cornell University began with hundreds of dissected guts from psyllids feeding on either healthy or CLas-infected citrus plants. More C-Type LectinsReport and protein sequencesC-Type Lectins(CTLs) are calcium dependent extracellular proteins involved in recognition of glycans. A total of 10 models were found and annotated. Refer to C-type lectin gene report for further details. The Basecamp page and FTP site contain the data sets and instructions for annotation.Relish-like ProteinsReport and protein sequencesRelish-like proteins are transcription factors and are inlvolved in Imd pathway. The Basecamp page and FTP site contain the data sets and instructions for annotation.Galactoside-Binding LectinsReport and protein sequencesGalactoside-Binding Lectins (GALEs) or galectins bind to beta-galactoside sugars. GALEs are implicated in innate immunity as they might be involved in microbial recognition and/or phagocytosis. The Basecamp page and FTP site contain the data sets and instructions for annotation.Abstract submissions are now open for the Joint Conference of the International Organization of Citrus Virologists XXI (IOCV XXI) and the International Research Conference on Huanglongbing VI (IRCHLB VI) to be held in Riverside, CA from March 10-15, 2019.Third Annual CitrusGreening Solutions meetingThe Third Annual CitrusGreening Solutions meeting will be held on Dec 10-12th,2017 at University of California, Davis campus in CA.International Research Conference on HuanglongbingThe IRCHLB V meeting was held in Orlando, FL from March 15-17th, 2017.
