  abstract = {{S}tems of susceptible and resistant cassava plants have been cytologically investigated for their defense reactions to an aggressive strain of {X}anthomonas campestris pv. manihotis. {H}istochemistry, in conjunction with gold cytochemistry, revealed that in susceptible and resistant plants, phloem and xylem parenchyma cells displayed a wide range of responses that limited the bacterial growth within the infected plants. {L}ignification and suberization associated with callose deposition were effective mechanisms that reinforced host barriers in the phloem. {I}n the infected xylem, vessels were plugged by a material of pectic and (or) lignin-like origin. {F}lavonoids have been seen to be incorporated in secondary cell wall coatings. {T}hese reactions occurred at a higher intensity in the resistant plants. {T}he number of phoem and xylem cells producing autofluorescent compounds was higher in infected resistant plants than in susceptible plants. {R}eactions have been observed in the resistant variety only, such as secretion of phenol-like molecules by tyloses and hyperplasic activity of phloem cells that compartmentalized bacterial lysis pockets, which are potent secondary inoculum sources.{K}ey words: lignin, suberin, callose, phenol, tylose, flavonoid, pectin},
