O InPP marcou presença no Encontro com orizicultores e técnicos(as) em Portugal, promovido pela EDAF, que decorreu no dia 5 de março, no Pólo de Inovação de Salvaterra de Magos, em Santarém.

A Diretora de Biosoluções do InPP, Cristina Azevedo, integrou o painel de oradores convidados, tendo apresentado a comunicação intitulada “A problemática da Pyricularia na cultura do arroz”. A apresentação incidiu sobre os principais desafios fitossanitários associados a esta doença, que continua a constituir uma das maiores ameaças à produção de arroz a nível mundial e também em Portugal.

O encontro reuniu produtores, técnicos e especialistas da fileira do arroz, proporcionando um espaço de partilha de conhecimento e debate sobre soluções atuais e em desenvolvimento para o controlo da piriculariose. Foram igualmente abordados outros temas relevantes para a sustentabilidade e produtividade da cultura, nomeadamente a gestão da fertilização.

A participação do InPP neste tipo de iniciativas reforça o compromisso da instituição com a inovação, a transferência de conhecimento e o desenvolvimento de soluções sustentáveis para a agricultura nacional.

O InPP agradece à EDAF e ao COTArroz o convite e a organização deste importante encontro, esperando que esta colaboração continue a fortalecer-se no futuro.

The project TomaBioTec started in January with the aim of developing and validating innovative solutions that contribute to a more sustainable and efficient production of tomatoes in the industry, in line with the current challenges of the agri-food sector, by integrating biotechnology and digital technologies.

The initiative aims to evaluate, under real field conditions, the effectiveness and efficiency of a biosolution with bioprotective and/or biostimulant properties, developed by InnovPlantProtect (InPP), This could help improve the quality and productivity of industrial tomato crops.

The rehearsals take place at Alentejo and Spanish Extremadura and combine traditional agronomic methods with advanced technologies, such as drones, multispectral sensors and artificial intelligence models. This approach allows detailed monitoring of the health of the crop, the presence of pests and diseases and the impact of the bioproduct throughout the production cycle.

The project “TomaBioTec: New biological and digital solutions for tomato crop protection and fertilization” is led by the InPP, in collaboration with the Centro Tecnológico Nacional Agroalimentario Extremadura (CTAEX) and Cordeiro Group, and was selected as one of the winners of the 7th edition of the Promove Program, The prize was awarded by the “la Caixa” Foundation, in partnership with Banco BPI and the Foundation for Science and Technology (FCT), in the category of innovative pilot projects.

This project reinforces the commitment to biological and digital solutions as drivers of more sustainable, competitive agriculture based on scientific evidence, with a direct impact on producers and industry.

InnovPlantProtect (InPP) was present at the XVI National Maize Congress, which also included the 2nd Meeting of Cereal Crops, organized by ANPROMIS, in collaboration with ANPOC and AOP. The event took place on February 11 and 12 at CNEMA in Santarém, bringing together national and international experts to discuss the sector's main challenges.

António Saraiva, Executive Director of InPP, took part in the panel “Cereal Production: What technical challenges are we facing?”, where he highlighted the decisive role of research in responding to the emerging challenges of cereal production, in a context of growing demographic, environmental and economic pressure.

“I'm proud that today, after seven years, we have 28 researchers working full-time on this topic, 12 of whom have PhDs, with experience in crops such as rice, which has been central to our work,” he said, emphasizing the multifunctional and international nature of InPP's teams.

He also pointed out that the work being done extends beyond rice to include maize, through ongoing projects and new operational groups focused on emerging crop problems. Among the initiatives in the spotlight is an application to Horizon Europe focused on developing improved and more resilient varieties.

For António Saraiva, anticipation is the key to success: “These challenges can't wait too long to be discussed or resolved. The sooner we anticipate the issues, the easier, more effective and more economical the solutions will be.”

In a debate that also marked the 40th anniversary of Portugal's integration into Europe and the role of the Common Agricultural Policy in the cohesion of the European Union, one message was clear across the board: “Climate change is the biggest threat we have.”

InPP thus reaffirms its commitment to innovation, science and the development of sustainable solutions for the future of cereal crops.

Sometimes, if you're inside a building, it's hard to tell whether or not it's raining outside. However, you will easily conclude that it is raining if you see people with open umbrellas. The umbrella is an accessory that helps human beings deal with their environment.

Bacteria can also use “accessories” to better cope with their environments. These accessories, however, have much more profound effects on the lives of microbes, as they take the form of genes that can be integrated into their own genomes. These “accessory” genes are obtained from other microbes or from the environment, and can play various roles, from allowing bacteria to resist antibiotics to enabling symbiotic associations with plants.

At InPP, the Data Management and Risk Analysis Department is comparing bacterial genomes to identify those that have “accessory” genes that can help plants defend themselves better against pathogens. On the other hand, these analyses also allow us to rule out bacterial strains that could have adverse effects. This information will be crucial for identifying microbes and microbial characteristics that are important for plant protection.

Tobacco whitefly uses a stolen gene to avoid the host's defenses. The discovery is highly relevant to pest control.

The first known case of a natural gene transfer from a plant to an insect has been identified by an international team of researchers. The insect is a whitefly and the discovery could pave the way for new pest control strategies, according to a report published in the newspaper Nature.

Scientists have discovered that Bemisia tabaci appropriated a gene from a host plant millions of years ago, reveals a article published in Cell. The gene allows this pest to neutralize a toxin produced by certain plants to defend themselves against insects.

This aleirodid, also known as the bean or sweet potato whitefly, although it attacks many other vegetable crops, is a worldwide pest and one of the most destructive we know of. A Bemisia tabaci ingests the sugary sap of hundreds of types of plants, excreting a sweet, sticky substance, honeydew, which then serves as a medium for fungi to grow. Whiteflies are also vectors for more than a hundred viruses that are pathogenic to plants.

“It's a remarkable example of how the study of evolution can underpin new approaches to applications such as crop protection,” says Andrew Gloss, who studies plant-pest interactions at the University of Chicago in the USA. The study suggests that inhibiting the gene identified could make this whitefly vulnerable to the toxin, opening up a new way of combating this pest.

Protecting plants from pathogens without genetically modifying crops? A team of Chinese researchers suggests an alternative strategy in the latest issue of Plant Communications.

The biotechnological methods that currently exist to create crops that are resistant to pests and diseases are limited in their applicability, mainly because they are based on transgenics or surface application (which does not allow access to the inner areas of the plant). A scientists' proposal involves the use of small RNA produced by beneficial microbes for crop protection, guaranteeing the stability and delivery of these RNAs to the appropriate place and time.

RNA associated with beneficial microbes in the microbiome to protect crops against pathogens.

The strategy, which eliminates “the need for genetic modification of cultures”, assumes that small RNAs (sRNAs) can be transferred from the microbiome to the host and pathogen, or between elements of the microbiome.

sRNAs are the crucial molecular devices of so-called gene silencing via RNA interference, a mechanism that regulates gene expression at both the transcriptional and post-transcriptional levels.
