AbstractThis study aimed to comprehensively analyze primary and secondary metabolites of three different-colored (white, pale green, and green) pak choi cultivars (Brassica rapa subsp. chinensis) using gas chromatography attached with time-of-flight mass spectrometry (GC-TOFMS) and high-performance liquid chromatography (HPLC). In total, 53 primary metabolites were identified and subjected to partial least-squares discriminant analysis. The result revealed a significant difference in the primary and secondary metabolites between the three pak choi cultivars. In addition, 49 hydrophilic metabolites were detected in different cultivars. Total phenolic and glucosinolate contents were highest in the pale green and green cultivars, respectively, whereas total carotenoid and chlorophyll contents were highest in the white cultivar. Superoxide dismutase activity, 2,2-diphenyl-1-picrylhydraz scavenging, and reducing power were slightly increased in the white, pale green, and green cultivars, respectively. In addition, a negative correlation between pigments and phenylpropanoids was discovered by metabolite correlation analysis. This approach will provide useful information for the development of strategies to enhance the biosynthesis of phenolics, glucosinolates, carotenoids, and chlorophyll, and to improve antioxidant activity in pak choi cultivars. In addition, this study supports the use of HPLC and GC-TOFMS-based metabolite profiling to explore differences in pak choi cultivars.

A preservação das estruturas de resistência de Plasmodiophora brassicae, em condições laboratoriais, é dificultada pelo fato de se tratar de um parasita obrigatório. O método de congelamento, utilizando freezer, comum foi testado com o objetivo de viabilizar a sobrevivência e a preservação de suas características infectivas. Raízes de diferentes brássicas, naturalmente infectadas por P. brassicae, contendo sintomas típicos de hérnia, de uma mesma propriedade localizada no município de Pardinho, Estado de São Paulo, foram coletadas em diferentes épocas e imediatamente congeladas, em freezer, a aproximadamente -20ºC. Os tratamentos foram divididos da seguinte maneira: T1: hérnias congeladas por 389 dias (rúcula); T2: hérnias congeladas por 242 dias (brócolis); T3: hérnias congeladas por 21 dias (couve chinesa) e T4: testemunha (sem inóculo). Os testes de patogenicidade, após diferentes períodos de armazenamento, foram realizados em condições de casa de vegetação (25±2ºC). Cada planta de uma variedade suscetível de couve-chinesa (Pak choi) foi inoculada com 2mL da suspensão de esporos de cada tratamento, na concentração de 10(7) esporos.mL-1. Cada tratamento contou com seis repetições distribuídas em blocos ao acaso. Passadas cinco semanas após a inoculação, as raízes das plantas foram lavadas e avaliadas. Houve diferença significativa entre os tratamentos. Os materiais congelados, entre 21 a 242 dias preservaram suas características infectivas, mostrando que o método de congelamento em freezer, nesse período, pode ser uma boa opção para a preservação das estruturas de resistência deste patógeno.

In plants, heptahelical proteins (HHPs) have been shown to respond to a variety of abiotic stresses, including cold stress. Up to the present, the regulation mechanism of HHP5 under low temperature stress remains unclear. In this study, BcHHP5 was isolated from Pak-choi (Brassica rapa ssp. chinensis cv. Suzhouqing). Sequence analysis and phylogenetic analysis indicated that BcHHP5 in Pak-choi is similar to AtHHP5 in Arabidopsis thaliana. Structure analysis showed that the structure of the BcHHP5 protein is relatively stable and highly conservative. Subcellular localization indicated that BcHHP5 was localized on the cell membrane and nuclear membrane. Furthermore, real-time quantitative polymerase chain reaction (RT-qPCR) analysis showed that BcHHP5 was induced to express by cold and other abiotic stresses. In Pak-choi, BcHHP5-silenced assay, inhibiting the action of endogenous BcHHP5, indicated that BcHHP5-silenced might have a negative effect on cold tolerance, which was further confirmed. All of these results indicate that BcHHP5 might play a role in abiotic response. This work can serve as a reference for the functional analysis of other cold-related proteins from Pak-choi in the future.
