“…The histology of maize stems was also largely revisited recently taking advantages of the development of microscopy, combined with automated image analysis workflows. To resolve histological traits, many strategies have been developed, for example, using a dark background with specific fluorescence filters [5,13], fluorescence from safranin stained stem sections [14], mass spectrometry imaging [15], X-ray microcomputed tomography [16][17][18][19][20], light background with flatbed document scanner [21], Maüle staining [12,22], phloroglucinol staining [23,24], or FASGA (Fucsina, Alcian blue, Safranina, Glicerina and Aqua) staining [12,[25][26][27]. These methods allowed the exploration of large sets of samples.…”
