This work examines abscission in tomato and finds that it is associated with programmed cell death and expression of the RNase LX, both of which occur on the distal side of the abscission zone (the part that falls off the plant), indicating asymmetric processes occurring during abscission. The findings are important for possible use in biotechnological control of tomato fruit abscission.

The results reveal that the immobilization of metals within the observed endomembrane structures present a structural and functional barrier and affect bioavailability. The combination of high spatial and chemical X-ray microscopy techniques highlights how in situ analysis can yield new insights into the complexity of the wheat aleurone layer, whose precise biochemical composition, morphology and structural characteristics are still not unequivocally resolved.

The leaf reflectance spectra of two heterophyllous aquatic plant species Polygonum amphibium and Nuphar luteum were compared and their relation to physical properties of the leaves examined. RDA indicated that in P. amphibium the length of trichomes and specific leaf area explained 72% and 7% variability of the spectra, whereas in N. luteum the most influential parameter, anthocyanin content, explained 56%. Spectral properties of different leaf types within a species vary more than in leaves of different species developed in similar environments. This suggests that any estimates of plant structure and function based on plant spectral signatures should be used with caution.
