Gejala kuning mirip seperti infeksi fitoplasma ditemukan pada pertanaman wortel di Jawa Barat. Penelitian bertujuan mengidentifikasi tanaman dan serangga wereng yang berasosiasi dengan gejala Bogor Bandung. Wereng terdiri atas 5 spesies daun (Hemiptera: Cicadellidae), yaitu Balclutha incisa (Matsumura), Orosius argentatus (Evans), Cicadulina bipunctata Empoascanara indica (Datta), Exitianus ind...

Leafhoppers (Hemiptera: Auchenorrhyncha: Cicadellidae) account for more than 80% of all "Auchenorrhynchous" vectors that transmit phytoplasmas. The leafhopper populations in two almond witches'-broom phytoplasma (AlmWB) infected sites: Tanboureet (south of Lebanon) and Bourj El Yahoudieh (north of Lebanon) were surveyed using yellow sticky traps. The survey revealed that the most abundant speci...

DNA methylation is believed to play important roles in regulating gene expression in plant growth and development. Paulownia witches' broom (PaWB) infection has been reported to be related to gene expression changes in paulownia plantlets. To determine whether DNA methylation is associated with gene expression changes in response to phytoplasma, we investigated variations in genomic DNA sequenc...
