The allelopathy of alien plants is critical to their successful invasion. In nature, two can co-invade the same habitat. Changes in forms nitrogen may have potential alter invasion process by causing alterations allelopathy. This study aimed evaluate individual and combined from Asteraceae family, Solidago canadensis L. Conyza (L.) Cronq. examined effects aqueous leaf extracts with different (N...

Thermoinhibition, or failure of seeds to germinate at warm temperatures, is common in lettuce (Lactuca sativa) cultivars. Using a recombinant inbred line population developed from a lettuce cultivar (Salinas) and thermotolerant Lactuca serriola accession UC96US23 (UC), we previously mapped a quantitative trait locus associated with thermoinhibition of germination to a genomic region containing ...

Diante da preocupação com os impactos negativos que percolados de aterros sanitários podem causar no meio ambiente, o presente estudo teve por objetivo caracterizar amostras efluente bruto e tratado aterro sanitário através análises físico-químicas avaliar a toxicidade utilizando semente alface (Lactuca sativa) como organismo teste, verificando efeitos na germinação. Para tanto, foram preparada...

vp2 protein is the major host protective immunogen of infectious bursal disease virus (ibdv) of chickens. plants are now gaining widespread acceptance as a general platform for the large scale production of recombinant proteins including vaccine, antibodies and pharmaceuticals. in present study vp2 gene of an iranian isolate of ibdv was cloned under strong plant expression promoter camv35s and ...
