With in-depth knowledge of the strains and breeds that exist in the country, the Elvas CoLAB can thus devise more efficient and targeted combat strategies.

InnovPlantProtect (InPP) is analyzing yellow rust samples collected from wheat fields in Portugal. Identification at InPP is carried out using PCR techniques and analysis of DNA fragments using SeqStudio, which makes it possible to determine the lineage of the fungus by examining molecular markers.

The polymerase chain reaction, or PCR, is a technique that allows you to copy a specific region of DNA, in vitro. SeqStudio is a sequencing machine that also allows the length of fragments to be measured, from which it is possible to correlate the size of different molecular markers with a given lineage.

Yellow rust is a disease caused by the fungus Puccinia striiformis f. sp. tritici, This pathogen, which affects wheat and other cereals all over the world, jeopardizes the future and stability of cereal crops. This pathogen is biologically very dynamic, adapting quickly to climate change and to the resistant cereal varieties that are being introduced onto the market.

So far, the PstS10 strain, the most prevalent in Europe, has been identified. PstS10 has proved to be very aggressive, affecting wheat varieties that were previously resistant to yellow rust. The race of this strain was determined by RustWatch in Denmark to be Benchmark. InPP sent samples to this European project to combat wheat rusts, which, among many other aspects, also involves genotyping and identifying the strains and races of the fungus that causes yellow rust.

With in-depth knowledge of the strains and races present in Portugal, the InPP can therefore devise more efficient and targeted combat strategies, by improving wheat varieties resistant to yellow rust and developing bioinspired control agents.

InnovPlantProtect's project to combat this disease was started in March 2020.

No product currently on the market is capable of eliminating Xylella fastidiosa, the Commission for the Regional Budget of Puglia, southern Italy. The bacterium continues to seriously affect olive groves in Italy's main olive oil producing region.

“The two products marketed in recent weeks as a treatment against the drying out of trees, and useful for bringing plants back to their original glory, are a mixture of natural soaps or adjuvants,” said the director of Puglia's phytosanitary observatory, Salvatore Infantino, at a public hearing, quoted by OliveOilTimes. The heads of the regional budget commission for this area of southern Italy, which forms the “heel” of the “boot”, guarantee that there are currently no products on the market capable of eliminating the bacteria Xylella fastidiosa of infected trees, particularly olive trees.

This bacterium is the most active pathogen affecting olive trees in Italy's main olive oil producing region. For Salvatore Infantino, the development of a product capable of combating it remains an important goal for many of those striving to reduce the devastation caused by the bacteria. Xylella fastidiosa.

Public authorities must not make the mistakes of the past by giving credence to unscientific theories that have already caused so much damage and wasted so much time.

Fabiano Amati, president of Puglia's regional budget committee

A Xylella fastidiosa was first detected in the European Union precisely in Puglia, in October 2013, and was responsible for an outbreak that, by 2015, had already infected one million olive trees in this Italian region alone. “Currently, good agricultural practices and eradication are the only weapons we have against the Xylella, It's a way of saving time while we wait for a truly effective treatment,” says Salvatore Infantino.
