A comparative study of the lectins from the families Amaryllidaceae and Alliaceae reveals many common features: all bind D-mannose exclusively and have similar molecular structures and amino acid compositions. All these lectins contain subunits of M, 11500-14000 which are not linked by disulphide bonds and occur as dimers (in Allium sativum, A. vineale, A. ursinum, A. moly, Narcissus pseudonarc...

A cebola (Allium cepa L.) está entre as culturas mais cultivadas no Semiárido baiano, atingindo, em 2019, uma produção de cerca 241 mil toneladas apenas estado da Bahia e 317 reais.

The genotoxic potential of the commercial herbicide Illoxan (containing 284 g/L diclofop-methyl) was determined by using chromosome aberrations in Allium cepa root tip cells. The EC50 value was determined as 150.00 mg/L using a root growth inhibition test and then the roots were treated with 37.50, 75.00, and 150.00 mg/L concentrations for 12, 24, and 48 h. The results indicated that Illoxan si...

Since folk medicine has been greatly appreciated for centuries, many researchers decided to study more deeply the curative qualities of plants. In the present study, meristematic cells of Allium cepa L. were used as vegetal test system and bone marrow cells of Wistar rats as animal test system. Both were treated in vivo to evaluate whether the plants Averrhoa carambola L., Syzygium cumini (L.) ...

In the present study, leachate toxicity of a municipal solid waste landfill located in the Sinos River Valley region (southern Brazil) was evaluated using plant bioassays. Leachate toxicity was assessed by analysis of seed germination and root elongation of lettuce (Lactuca sativa L.) and rocket plant Eruca sativa Mill.) and root elongation of onions Allium cepa L.). Bioassays were performed by...
