Chemotaxonomic study of Citrus, Poncirus and Fortunella genotypes based on peel oil volatile compounds--deciphering the genetic origin of Mangshanyegan (Citrus nobilis Lauriro). [PDF]

PLoS ONE, 2013
Volatile profiles yielded from gas chromatography-mass spectrometry (GC-MS) analysis provide abundant information not only for metabolism-related research, but also for chemotaxonomy.

Differential expression of genes identified from Poncirus trifoliata tissue inoculated with CTV through EST analysis and in silico hybridization

Genetics and Molecular Biology, 2007
Citrus is the most important fruit crop in Brazil and Citrus tristeza virus (CTV) is considered one of the most important pathogens of citrus. Most citrus species and varieties are susceptible to CTV infection.

Targeting the "bitterness gene" by genome editing abolishes synthesis of bitter flavanones in citrus; prospects for new varieties and extended climates for cultivation. [PDF]

Plant J
SUMMARY Bitterness in citrus fruit is conferred by flavanone‐neohesperidosides, whose accumulation is catalyzed by a single enzyme flavanone‐7‐O‐glucosides‐1,2‐rhamnosyltransferase (1,2RhaT), expressed in both leaves and fruit. To eliminate citrus bitterness, we used CRISPR/Cas9 genome editing to inactivate the 1,2RhaT gene in grapefruit (Citrus ...

Aseptic isolation of leaf protoplasts from Citrus, Poncirus, Citrus × Poncirus hybrids and Severinia for use in somatic hybridization experiments

Scientia Horticulturae, 1987
Abstract An efficient protocol has been developed for the aseptic isolation of leaf protoplasts from Citrus and citrus relatives. Consistently high yields (2–6 × 10 7 protoplasts/g fresh weight tissue) of leaf protoplasts were isolated from new leaves taken from vigorously growing plants maintained in a growth chamber. Critical parameters included

Rootstock impacts on citrus flush dynamics, vegetative growth, and Diaphorina citri infestation and dispersion: Implications for huanglongbing management

Pest Management Science, Volume 82, Issue 9, Page 8795-8809, September 2026.
Dwarfing citrus rootstocks restrict flush shoot growth on the scion, thereby reducing Asian citrus psyllid infestation, dispersal, and huanglongbing (HLB) progression. These findings support the use of dwarfing rootstocks as an effective cultural strategy in integrated HLB management for citrus orchards.
