Magnetic resonance imaging of sugar beet taproots in soil reveals growth reduction and morphological changes during foliar Cercospora beticola infestation.

Bottom Line: However, during this period, the volumetric growth of the taproot had already started to decrease.Additionally, inoculated plants showed a reduction of the increase in width of inner cambial rings while the width of outer rings increased slightly compared with non-inoculated plants.This response partly compensated for the reduced development of inner rings that had a vascular connection with Cercospora-inoculated leaves.

Images of HS and LS sugar beet plants, inoculated or not inoculated with C. beticola. Non-inoculated treatment of the HS (A) and LS (B) genotype, and inoculated treatment of the HS (C) and LS (D) genotype. For plant cultivation, plants were grown in PVC pots of 40cm depth to allow deeper root growth. Each pot was labelled with an individual code (white labels) to match measurements to plants. Images were acquired shortly before harvest at 90 dpi.

Figure 1: Images of HS and LS sugar beet plants, inoculated or not inoculated with C. beticola. Non-inoculated treatment of the HS (A) and LS (B) genotype, and inoculated treatment of the HS (C) and LS (D) genotype. For plant cultivation, plants were grown in PVC pots of 40cm depth to allow deeper root growth. Each pot was labelled with an individual code (white labels) to match measurements to plants. Images were acquired shortly before harvest at 90 dpi.

Mentions: In experiment 1, sugar beets grew in pots until harvest at 90 dpi, showing phenotypic differences between genotypes with respect to the development of non-inoculated (Fig. 1A, B) and inoculated shoots (Fig. 1C, D). After inoculation, CLS disease severity increased in leaves of both genotypes from single leaf spots to the final loss of the inoculated leaves (Fig. 2A). Disease severity was estimated by the combination of two scoring scales (Rossi et al. 1989; Shane and Teng, 1992), and the average number of infected leaves per plant (ILPa) was calculated (see Equation 1).
