New tool facilitates genetic mapping of polyploid plants
Publicado em 11 novembro 2019
An innovative genetic mapping system for polyploid species promises to facilitate the work of scientists and plant breeders who use genomics to develop varieties that are more productive and resistant to disease or drought. Polyploids are organisms with more than two sets of chromosomes. Many plant species of economic value such as potato, wheat, cotton and sugarcane, are polyploids.
The research was conducted at the University of São Paulo's Luiz de Queiroz College of Agriculture [...]

Innovative approach to tackling pesticide resistance evolution, the study will focus on Brazil
Publicado em 18 junho 2019A new £620,000 study led by the University of Stirling is taking a "revolutionary approach" in attempting to tackle resistance to pesticides in insects. Pesticide resistance is a serious problem for the agriculture industry worldwide, with pests consuming between 10 and 20 percent of all global crops while growing or in storage. The study will focus on Brazil, where the agricultural economy loses approximately $17.7 billion (£13.6 billion) a year to outbreaks of insects [...]ver notícia -
Software locates sugarcane genes of interest
Publicado em 17 maio 2019Plants have larger and more complex genomes than all animals, be they mammals, birds, reptiles or amphibians. Fishes are the exception to the rule. Human DNA consists of some 3.2 billion base pairs spread out over 23 pairs of chromosomes, for a total of 46 chromosomes. The genome of wheat (Triticum aestivum), however, comprises 17 billion base pairs divided into 21 pairs of chromosomes (a total of 42). The genome of sugarcane (Saccharum spp.) contains 10 billion base pairs in 100-130 [...]ver notícia
