Arabidopsis Landsberg erecta is one of the most popular ecotypes and is used widely for both molecular and genetic studies. It harbors the erecta (er) mutation, which confers a compact inflorescence, blunt fruits, and short petioles. We have identified five er mutant alleles from ecotypes Columbia and Wassilewskija. Phenotypic characterization of the mutant alleles suggests a role for the ER ge...

Quantitative trait loci (QTL) mapping was used to identify loci controlling various aspects of seed longevity during storage and germination. Similar locations for QTLs controlling different traits might be an indication for a common genetic control of such traits. For this analysis we used a new recombinant inbred line population derived from a cross between the accessions Landsberg erecta (Le...

The crude extracts and its fractions of the flower of Tagetes erecta Linn. were tested for insecticidal activity against a stored product insect pest, Tribolium castaneum (Herbst). The chloroform fraction showed highest toxicity against both the larvae and adults of Tribolium castaneum followed by 50 petroleum ether fraction and ethanol extract. The LC values of chloroform fraction against firs...

Decorative ornamental plants have been applied as hyperaccumulators/phytoremediators to a wide spectrum of heavy metal contaminants. In this study, pot culture experiments were conducted investigate the Sn tolerance and accumulation in Impatiens balsamina L., Mirabilis jalapa L. Tagetes erecta order assess possibility these three be used phytoremediators Sn-contaminated soil. Results show that ...

Chromium is a heavy metal that toxic, bioaccumulative, persistent, and cannot be decomposed in the environment. The Cr6+ ion chromium has highest toxicity among other ions, so its presence environment hazardous for plants, animals, humans. Sulfur an essential element whose can reduce concentrations terrestrial by inhibiting uptake of plants. Tagetes erecta bioremediation agent plant remediate l...

Para conocer el cruzamiento intraespecífico y su posible implicación en la domesticación del Cempoalxochitl (Tagetes erecta L.), se realizó manualmente autopolinización polinización cruzada intrapoblacional (PaP) T. cultivada pariente silvestre. La silvestre produjo poca semilla (17 %), mientras que cultivado fue mayor (74 %); con PaP, hubo alta producción de semillas ambas poblaciones (91 a 95...
