Fig. 3: Mycorrhizal phenotype of RNAi lines and WT 8 weeks after inoculation with Rhizophagus irregularis.
From: Silencing MdGH3-2/12 in apple reduces drought resistance by regulating AM colonization
a–d Root segments stained with trypan blue. a Roots of WT under the NM condition. b–d Arbuscules of WT, Ri-1 and Ri-9. e Colonization percentages in the RNAi lines and WT. ‘F’, frequency of colonization in the root system; ‘a’, arbuscule abundance (percentage) in the colonized root sections. Bars = 100 μm. Data are expressed as means ± SDs (n = 3). Data with different letters differ significantly (P < 0.05), as determined by one-way ANOVA and Tukey’s test
