This study was carried out to assess the ecotoxicity of soil affected by wildfire using two laboratory toxicity tests, and investigate possibility application selected amendment into burnt in order improve its properties for faster post-fire reclamation. A phytotoxicity test is a fast-indicative revealing acute performed on quickly growing plant species Sinapis alba L. Lepidium sativum L., whil...

The effects of intercycle cover crops on Rotylenchulus reniformis population densities in pineapple were evaluated in one greenhouse and two field experiments. In the greenhouse, Crotalaria juncea, Brassica napus, and Tagetes erecta were planted for 3 months and then incorporated. These treatments were compared to weedy fallow with or without 1,3-dichloropropene (1,3-D) in three soils (Makawao ...

Plant chloroplasts contain transcription factors that functionally resemble bacterial sigma factors. We have cloned the full-length cDNA from mustard (Sinapis alba) for a 53 kDa derived polypeptide that contains similarity to regions 1.2-4.2 of sigma70-type factors. The amino acid sequence at the N-terminus has characteristics of a chloroplast transit peptide. An in vitro synthesized polypeptid...

Sinapis alba is an important condiment crop and can also be used as a phytoremediation plant. Though it has important economic and agronomic values, sequence data, and the genetic tools are still rare in this plant. In the present study, a de novo transcriptome based on the transcriptions of leaves, stems, and roots was assembled for S. alba for the first time. The transcriptome contains 47,972...

Glutamine synthetase of roots, etiolated cotyledons and green leaves from mustard plants cannot all clearly be separated by DEAE-Sephacel chromatography. However, the enzyme of the roots, etiolated cotyledons and green leaves, respectively, differed in the kinetic properties deter­ mined in the crude extract. The root enzyme showed a pH-optimum of about 6.9, a Km value of 3 m M for glutamate an...

ABSTRACT: Mustard is a natural multi-functional additive with strong hot flavor. In this research, powdered yellow mustard (Sinapis alba) was heated by 21 different thermal processes, statistically designed by Response Surface Methodology to evaluate the effects of combinations of heating media (hot air, hot water and steam) and heating time (0-20 min) on residual myrosinase activity, the minim...

Cadmium is an essential element for plant growth and development. Its accumulation in soil more hazardous to human animal health than plants microorganisms. A pot greenhouse experiment was conducted determine the usability of Sinapis alba L. Avena sativa phytoremediation contaminated with cadmium verify cellulose viability remediation under pressure doses from 4 16 mg Cd2+ kg−1 d.m. (dry matter...
