A rapid and simple determination method of seven fungicides, thiabendazole (TBZ), pyrimethanil (PYR), o-phenylphenol (OPP), fludioxonil (FLD), azoxystrobin (AZX), imazalil (IMZ) and diphenyl (DP) in citrus fruits by LC-MS and HPLC-FL was developed. The seven fungicides were extracted with acetonitrile from citrus fruits and cleaned up with Z-Sep/C18 cartridges. The LC separation was performed on a phenyl-hexyl column with methanol-acetonitrile-10 mmol/L ammonium formate (10 : 35 : 55) as a mobile phase. The recoveries from citrus fruits fortified with the compounds at the MRLs and at 0.1 μg/g ranged from 85.4 to 106.3% and from 75.8 to 99.7%, respectively. The quantitation limits (S/N=10) were 0.03-0.07 μg/g.

Plant viruses have been known to alter host metabolites that influence the attraction of insect vectors. Our study investigated whether (CYVCV) infection influences vector attractiveness, focusing on the citrus whitefly, (Ashmead). Free choice assays showed that citrus whiteflies exhibited a preference for settling on CYVCV-infected lemon plants versus healthy control plants.

The (citrus) plant produces various phytohormones due to the significant involvement of the carotenoid cleavage oxygenase () gene family in its growth and development. genes can be divided into two main categories: (9-cis-epoxy carotenoid dioxygenase), responsible for abscisic acid (ABA) production, and (carotenoid cleavage dioxygenase), involved in pigment and strigolactone formation. To better understand the roles and positions of gene members in relation to these hormones, researchers analyzed the clementine genome.

Roots play essential roles in the acquisition of water and minerals from soils in higher plants. However, water or nutrient limitation can alter plant root morphology. To clarify the spatial distribution characteristics of essential nutrients in citrus roots and the influence mechanism of micronutrient deficiency on citrus root morphology and architecture, especially the effects on lateral root (LR) growth and development, two commonly used citrus rootstocks, trifoliate orange ( L.

Lung malignancies, including cancerous lymphangitis and lymphomas, can mimic interstitial lung diseases like cryptogenic organizing pneumonia (COP) on imaging, leading to diagnostic delays. We aimed to identify potential biomarkers to distinguish between these conditions. We analyzed bronchoalveolar lavage fluid from 8 patients (4 COP, mean age 59.
