1 H NMR analysis of Citrus macrophylla subjected to Asian citrus psyllid ( Diaphorina citri Kuwayama) feeding

摘要: The Asian citrus psyllid (ACP) is a phloem-feeding insect that can host and transmit the bacterium Candidatus Liberibacter asiaticus (CLas), which putative causative agent of economically important disease, Huanglongbing (HLB). ACP are widespread in Florida, spreading California; they primary mode CLas transmission groves. To understand effects feeding, different numbers [0 (control), 5 (low), 15–20 (medium), 25–30 (high)] were allowed to feed on Citrus macrophylla greenhouse plants. After 7 days leaves collected analyzed using 1H NMR. Metabolite concentrations from trees with feeding had higher variability than control trees. Many metabolites concentration low group relative control; however, high lower many control, including amino acids such as phenylalanine, arginine, isoleucine, valine, threonine, leucine. These results suggest density-dependent changes metabolism be measured by implications plant defense discussed.
