| Bromelain is a crude protein extract obtained from pineapple stems, which comprises a variety of proteolytic enzymes. It exhibits potential therapeutic activities against trauma, inflammation, autoimmune diseases and malignant disorders. In this study, we cloned BAA1 (the gene encoding fruit bromelain) into a plant expression vector that was then used to transform Brassica rapa and overexpress BAA1 under the control of the cauliflower mosaic virus (CaMV) 35S promoter. We demonstrate that constitutive overexpression of BAA1 in B. rapa confers enhanced resistance to the soft rot pathogen Pectobacterium carotovorum ssp. carotovorum. These results suggest that it could be utilized for protecting plants from attack by bacterial pathogens |

| ABSTRACT Nitrogen (N) strongly affects plant growth. However, little is known about the effects of the ammonium/nitrate ratio on pakchoi (Brassica rapa), especially its glucosinolates (GSs) contents which are involved in plant defense and many of them benefit to human health. The aim of this study was to evaluate the effects of a constant N supply (8 mM) but with five ammonium/nitrate ratios (namely 0/8 mM, 2/6 mM, 4/4 mM, 6/2 mM and 8/0 mM) on the growth of pakchoi in a hydroponic system in 2 years. In both years, a higher biomass (dry weight) was in the 4/4 and 2/6 ammonium/nitrate treatments (2.3 and 2.2-fold compared to 8/0, respectively), with no significant difference in biomass between these two treatments. The biomass then decreased with increasing... |

| Brassicaceae family comprises plant species that are very important as vegetable crops, such as the species complex Brassica oleracea and Brassica rapa. Alternaria brassicicola and A. brassicae are among the most important pathogens of Brassicaceae causing Alternaria leaf spot disease. The occurrence and prevalence of Alternaria species causing leaf spots in brassica crops in Pernambuco was acessed, as well as the existence of a possible preference by vegetable host for these pathogens. Twenty-eight fields were surveyed in the Agreste region of Pernambuco state, in the 2005 and 2006 growing seasons. In each year, 10 Chinese cabbage, six cabbage, six cauliflower and six broccoli fields were visited. In each field, 50 leaves showing at least five lesions... |
