β-Amino-n-butyric Acid Regulates Seedling Growth and Disease Resistance of Kimchi Cabbage

Abstract

Non-protein amino acid, β-amino-n-butyric acid (BABA), has been involved in diverse physiological processes including seedling growth, stress tolerance and disease resistance of many plant species. In the current study, treatment of kimchi cabbage seedlings with BABA significantly reduced primary root elongation and cotyledon development in a dose-dependent manner, which adverse effects were similar to the plant response to exogenous abscisic acid (ABA) application. BABA was synergistically contributing ABA-induced growth arrest during the early seedling development. Kimchi cabbage leaves were highly damaged and seedling growth was delayed by foliar spraying with high concentrations of BABA (10 to 20 mM). BABA played roles differentially in in vitro fungal conidial germination, mycelial growth and conidation of necrotroph Alternaria brassicicola causing black spot disease and hemibiotroph Colletotrichum higginsianum causing anthracnose. Pretreatment with BABA conferred induced resistance of the kimchi cabbage against challenges by the two different classes of fungal pathogens in a dose-dependent manner. These results suggest that BABA is involved in plant development, fungal development as well as induced fungal disease resistance of kimchi cabbage plant.

“…Many authors have shown beneficial properties of BABA, but only in plants. BABA is responsible for protection against abiotic and biotic stresses [28] and is involved in disease resistance and plant development [29], and its levels are elevated very quickly after biotrophic, necrotrophic, and hemibiotrophic pathogens [30]. What is interesting is that the changes in BABA in human diseases were not examined.…”

Differential defence responses of susceptible and resistant kimchi cabbage cultivars to anthracnose, black spot and black rot diseases

“…Recently it was demonstrated that disease resistance of kimchi cabbage seedlings (cv. Samrack-eolgari) against C. higginsianum was induced in the first and second true leaves by treatment with the non-protein amino acid b-amino-nbutyric acid (BABA; Kim et al, 2013). However, dosedependent BABA-induced disease resistance to the anthracnose was not different in the first and second leaves of the kimchi cabbage seedlings.…”

“…Plant defence elicitor benzothiadiazole (BTH) successfully controlled the anthracnose development in Chinese cabbage (Narusaka et al, 2008). Plant defence priming agent b-amino-n-butyric acid (BABA) also decreased disease incidence of anthracnose in kimchi cabbage seedlings showing a dose-dependent protection (Kim et al, 2013). However, integrated control methods suggested for kimchi cabbage anthracnose have been limited.…”
