Figure 6.

Detection of mannan using three different antimannan monoclonal antibodies on sections of Aloe helenae (a, b) and Aloe vera (c, d) hydrenchyma in (a, c) well‐watered, and (b,\c) drought‐stressed samples. LM21 binds (1,4)‐β‐D‐mannan/galactomannan/glucomannan, CCRCM170 binds acetylated mannan, and BS‐400‐4 binds (1,4)‐β‐D‐mannan. Calcofluor White (staining β‐(1,4) glucans) is used on all sections. The cell wall signal is marked by closed arrowhead and the intracellular signal with open arrowheads
