Dual protective roles of plant beneficial bacteria in drought resilience and suppression of tomato bacterial canker caused by Clavibacter michiganensis subsp. michiganensis

Abstract

Objective: This study aimed to evaluate the ability of two beneficial bacterial isolates to mitigate the effects of Clavibacter michiganensis subsp. michiganensis (Cmm) and drought stress on tomato plants. Materials and Methods: 30 isolates were screened for in vitro antagonism against Cmm; isolates TR21/1 and CA18 were selected for in vivo testing under Cmm infection, drought, and combined stress conditions. Results: Isolate TR21/1 showed the highest in vitro inhibition zone (27.26 mm) and reduced Cmm-related disease by 38-83% in vivo. Under drought stress, isolate CA18 increased plant biomass by 30-38%. Combined inoculation with TR21/1 and CA18 elicited the strongest response, increasing biomass by 124-174% and reducing disease severity by 56-69%. Conclusion: Both isolates were effective, but their combined application produced the greatest overall improvement.

Kuraklığa dayanıklılık ve Clavibacter michiganensis subsp. michiganensis'in neden olduğu domates bakteriyel kanserinin bastırılmasında bitki yararlı bakterilerinin ikili koruyucu rolleri

Abstract

Amaç: Bu çalışmada, iki yararlı bakteri izolatının Clavibacter michiganensis subsp. michiganensis (Cmm) ve kuraklık stresinin domates bitkileri üzerindeki olumsuz etkilerini azaltma potansiyelini değerlendirmeyi amaçlanmıştır. Materyal ve Yöntem: 30 izolat Cmm’ye karşı in vitro antagonizma açısından taranmış ve izolat TR21/1 ile CA18, Cmm enfeksiyonu, kuraklık ve kombine stres altında in vivo denemeler için seçilmiştir. Araştırma Bulguları: İzolat TR21/1, 27.26 mm ile en yüksek in vitro inhibisyonu göstermiş ve in vivo koşullarda Cmm kaynaklı hastalığı %38-83 oranında azaltmıştır. Kuraklık stresinde izolat CA18 bitki biyokütlesini %30-38 artırmıştır. TR21/1+CA18 kombinasyonu ise en güçlü etkiyi göstererek biyokütleyi %124-174 artırmış ve hastalık şiddetini %56-69 azaltmıştır. Sonuç: Her iki izolat etkili olmakla birlikte, kombinasyon uygulaması genel olarak en yüksek iyileşmeyi sağlamıştır.
