Description
Alireza Keshtkar, with four colleagues, describes a 2026 study of two viroids found in mulberry trees near Shiraz, Iran. Viroids are tiny rings of RNA that infect plants but make no protein. The trees showed cleared veins and bent, deformed leaves. One viroid is known from citrus, the other from hops.
Deep sequencing of leaf RNA first flagged both viroids, and lab tests found them only in trees with symptoms. The team built copies of each viroid in plasmids and used them to infect young mulberry plants. The young plants grew the same vein and leaf signs, and viroid RNA built up over six to eight months. Gene changes sat mostly in two zones of each viroid. The citrus viroid had not been confirmed in mulberry anywhere before.
