Experiments were carried out in controlled conditions to analyze the role of metabolism of glyphosate in Digitaria insularis (sourgrass) biotypes with differential response to the herbicide.

Summertime weeds as Digitaria sanguinalis in many agro-ecosystems exist. In several cases, a welldefined weed control could be able to predict the seed emergence, to know the physiological status of the seeds in the soil bank, as well as, the factors that control and involving their germination. The goal of this work is to establish a relationship between the thermal properties and the process ...

We have used a polymerase chain reaction (PCR) procedure to analyse low abundance complementary sense RNAs of Digitaria streak virus (DSV) from infected leaves of Digitaria setigera. This study has confirmed that both spliced and unspliced RNAs are synthesised by the same transcription unit. The position of the intron has been proven from sequencing cDNAs corresponding to the spliced RNA. Altho...
