Kev tiv thaiv muaj zog yuav tsum muaj cov cuab yeej tiv thaiv basal los kho cov lus teb raws sij hawm thiab cov lus tawm tswv yim los txhawb kev tiv thaiv kom muaj peev xwm kis tau tus kab mob.AGD2-LIKE DEFENSE RESPONSE PROTEIN 1 (ALD1) yog qhov xav tau rau kev sib sau ntawm cov nroj tsuag tiv thaiv teeb liab salicylic acid (SA) thaum thawj teev tom qab kis kab mob nrog cov kab mob Pseudomonas syringae thiab tseem raug kho los ntawm kev kis kab mob thiab SA.ALD1 yog ib qho aminotransferase nrog ntau lub substrates thiab cov khoom hauv vitro.Pipecolic acid (Pip) yog ALD1-dependent bioactive khoom tshwm sim los ntawm P. syringae.Ntawm no, peb tau hais txog lub luag haujlwm ntawm ALD1 hauv kev kho kom haum xeeb tiv thaiv kev nthuav dav ntxiv nrog rau qib thiab cov lus teb ntawm basal tiv thaiv tshuab.ALD1 xav tau cov tshuaj tiv thaiv kab mob PAD4 thiab ICS1 (ib qho SA synthesis enzyme) kom muaj kev tiv thaiv kab mob, tejzaum nws yog los ntawm lub voj voog transcriptional amplification ntawm lawv.Tsis tas li ntawd, ALD1 cuam tshuam rau kev tiv thaiv basal los ntawm kev tswj hwm microbial-associated molecular pattern (MAMP) receptor qib thiab kev ua haujlwm.Vascular exudates los ntawm tsis muaj kab mob ALD1-overexpressing nroj tsuag muab kev tiv thaiv hauv zos rau hom tsiaj qus thiab ald1 mutants tseem tsis tau ntxiv rau Pip.Peb suav hais tias, ntxiv rau qhov cuam tshuam rau Pip tsub zuj zuj, ALD1 tsim cov tsis-Pip metabolites uas ua lub luag haujlwm hauv kev tiv thaiv.Yog li, cov cim metabolite sib txawv tswj los ntawm tib lub enzyme cuam tshuam rau kev tiv thaiv basal thiab thaum ntxov tiv thaiv cov lus teb tom qab tiv thaiv, feem.
