Viral strain-specific differential alterations in Arabidopsis developmental patterns

Turnip mosaic virus (TuMV) is a potyvirus able to infect Arabidopsis. Different strains of TuMV differentially alter developmental Arabidop sistraits upon infection, most plant organs being affected by the global alteration. Two TuMV strains have been studied in this regard. The cover shows effects on flower development and pollen release. The radish-infecting JPN 1 isolate is a representative of the strain deeply altering the developmental pattern, but not impairing totally, stamen growth and pollen production (right upper panel). On the contrary,Arabidopsis infection by the brassica-infecting isolate UK 1 significantly shortens stamens and completely precludes pollen release (lower panel). The left upper panel shows an uninfected flower for comparison (Sánchez et al. DOI: 10.1094/MPMI-05-15-0111-R).
