    Article Title: Cross-kingdom microRNA transfer for the control of the anthracnose disease in cassava
    Article Snippet: Cassava anthracnose disease (CAD), caused by Colletotrichum gloeosporioides f. sp. manihotis, is one of the most important diseases that cause significant yield loss in cassava.. Recently, involvement of microRNAs (miRNAs), a class of small, single-stranded, non-coding RNAs, in the resistance against anthracnose disease has been indicated.. In this study, two cassava cultivars that have different degree of CAD susceptibility were utilized to investigate the differences in defense responses these cultivars exhibited and to examine the role of seven miRNA families (mes-MIR156, 159, 164, 171, 396, 408, and 530) during CAD infection.
