... to label the respective polymers are emerging, but are efficient only in thin roots or sections. Moreover, simultaneous imaging of the barrier constituents lignin and suberin remains problematic owing to their similar chemical compositions. Here, we describe a staining method compatible with single...

..., hypocotyls were collected, sectioned and stained with phloroglucinol to detect lignin deposition. Similar to previous observations ( Ikematsu et al., 2017 ), our GA treatments did not induce fiber formation in the bp-11 mutant, but we observed that they promoted fiber differentiation in all the other...

...: the separation of the fruit valves that protect the seeds (fruit dehiscence) and the detachment of the seeds from the funiculus connecting them to the mother plant (seed abscission). The key factors required to establish a proper lignin pattern for fruit dehiscence are SHATTERPROOF 1 and 2 (SHP1 and SHP2). Here...
