Structural and Biochemical Changes in Salicylic-Acid-Treated Date Palm Roots Challenged with Fusarium oxysporum f. sp. albedinis
Figure 2
Light micrographs of samples from JHL date palm root tissues inoculated by Fusarium oxysporum f. sp. albedinis (Foa) (×40). Proteins were specifically stained in dark blue with NBB and PAS stains starch reserves and cell walls in pink. (a) Control roots (UU); (b) untreated and infected roots (UI); (c) SA-treated roots (TU); (d) SA-treated and Foa-infected roots (TI); note the presence of proteins at the cell layer surrounding the xylem vessels (arrow). X: xylem vessels; Ph: Phloem tubes; Pc: cortical parenchyma; Phc: Phenolic-storing cells.
