DESCRIPTION:Fusarium oxysporum causes Fusarium wilt disease in many agricu
 ltural important crops. To understand how the fungus manipulates its hosts
  we identify the targets of its Secreted in Xylem (SIX) effectors. Previou
 sly we reported that SIX3 (Avr2) targets PAMP triggered immunity by compro
 mising the function of BIK1 (Blekemolen et al.\, 2023 MPP). SIX5 modulates
  the size exclusion limit of plasmodesmata allowing symplastic spread of S
 IX proteins such as SIX8 (Talbi et al.\, 2023 MPP\; 37\, 304\, Blekemolen 
 et al.\, 2022 FPS\;13).  The broadly conserved SIX8 effector targets speci
 fic members of the Topless (TPL) family (Aalders et al.\, 2024 PBJ\; 22\, 
 248). Tomato tpl1/tpl2 mutants and Arabidopsis thaliana tpr1/tpl double mu
 tants show resistance to Fusarium wilt\, designating TPLs as genuine S gen
 es. To study SIX8 function\, the effector was expressed in Arabidopsis Col
 -0. The SIX8 transformants exhibited a temperature-dependent growth phenot
 ype\, constitutive PR1 and PR2 expression\, and local (...).
