Polyamines may influence phytochelatin synthesis during Cd stress in rice

Although the metabolism of phytochelatins and higher polyamines are linked with each other, the direct relationship between them under heavy metal stress has not yet been clarified. Two approaches were used to reveal the influence of polyamine content on cadmium stress responses, particularly with regard to phytochelatin synthesis: putrescine pre-treatment of rice plants followed by cadmium stress, and treatment with the putrescine synthesis inhibitor, 2- (difluoromethyl) ornithine combined with cadmium treatment. The results indicated that putrescine pre-treatment enhanced the adverse effect of cadmium, while the application of 2- (difluoromethyl) ornithine reduced it to a certain extent. These differences were associated with increased polyamine content, more intensive polyamine metabolism, but decreased thiol and phytochelatin contents. The gene expression level and enzyme activity of phytochelatin synthase also decreased in rice treated with putrescine prior to cadmium stress, compared to cadmium treatment alone. In contrast, the inhibition of putrescine synthesis during cadmium treatment resulted in higher gene expression level of phytochelatin synthase. The results suggest that polyamines may have a substantial influence on phytochelatin synthesis at several levels under cadmium stress in rice.

The first MAKEathon in the Green Entrepreneurs of the Future project

Tomorrow, March 22, the first MAKEathon of the Green Entrepreneurs of the Future (GFF) project out of three, will take place at Árskóli in Sauðárkrókur. The other two MAKEathon will take place before Easter at Bolungarvík Primary School and Nesskóli in Neskaupstaður. The MAKEathon project is an innovation competition that lasts for two days

In this first MAKEathoni, 31 students in the ninth grade participate. They work together in teams competing to present a solution to the challenge:

How can we reduce the use of plastic when packing fish and shrimp?

They try to create a kind of prototype, among other things in collaboration with FabLab Íslands 'workshop in each place, in addition to which Matís' staff will be on site to assist.

Students saw the challenge when they received visits from the fisheries companies Dögun and FISK Seafood and were educated about their activities, which was one part of the GFF project. In addition, they gained insight into possible challenges in terms of the effects of climate change on the ocean and their immediate environment, which was part of one of the project's workshops, Studio 4. 

All GFF material will be made available after the project is completed.

The Green Entrepreneurs of the Future project started in schools in September 2021 and MAKEathonin is the last part of the project. The national competition between the three schools will take place in May and its results will be announced in the Innovation Week, on 20 May. The project is funded by the Climate Fund.

This winter, the television station N4 has recorded material for a television show about the project, and the filmmakers will be from them on site. The show will be shown on the television station this autumn, where the project will be presented in its entirety.

For more information, please contact the project manager Justine Vanhalst via email Justine@matis.is. Schools that want to participate in the future are especially encouraged to get in touch.

In the last issue of Bændablaðið, an interview was published with Sæmundur Sveinsson, director of genetic research at Matís, and the topic was a research project he is currently working on in order to protect genetic variability in sheep against rubella.

Bændablaðið's article "Project on the search for protective genetic mutations in sheep against rubella" discussed Matís' project, which is funded by the Professional Council for Sheep Breeding and is carried out in collaboration with Keldur. The project is about refining scabies gene analyzes in Iceland by adding genotypic analyzes of the protective variability that is best known for providing great protection against scrapie in sheep. This is the second of two projects in Iceland today that focus on scrapie analysis.

In the interview, Sæmundur discusses the possibilities inherent in these improvements, but emphasizes that this is not a quick fix, but that the project will possibly provide tools that can be used in the fight against riding in the long run.

Sample collection on a beach trip

The projects undertaken by apprentices and specialists at Matís are varied. Last week, Þóra Valsdóttir, project manager, went on a beach trip with interns Romain Canuel and Sabrina Rechtsteiner.

The reason for going on a beach trip was that in the project MINERVA came to sample collection. The aim of the MINERVA project is to make untapped life resources, in this case biomass of algae growing throughout Europe, higher under the head. This will be done by improving processing methods and thus contributing to less waste and the development of new, valuable high-quality products from the raw material.

The sampling went well, as a rich garden was grazed, as can be seen in the attached pictures.

The potatoes came as a surprise

At Matís, various researches are underway on vegetables for a grant from the Food Fund. The research aims to increase the quality and shelf life of vegetables but also to reduce waste in the value chain from harvest to consumer and find new ways to increase the value of by-products in the vegetable sector.

Recently completed a project that started in 2020 and dealt with the antioxidant activity and quality of vegetables. Antioxidant activity refers to the activity of antioxidants which are among the important substances in vegetables. Antioxidants are substances that provide the body with protection against the harmful effects of substances that promote oxidation. The health benefits have been attributed to the consumption of antioxidant vegetables.

Antioxidant activity was found in all vegetable samples but varied by species. Significant antioxidant activity in potatoes came as a surprise as antioxidants are often associated with colorful vegetables.

Cauliflower and broccoli, along with potatoes, were among the vegetables that scored the highest for antioxidant activity.

The healthiness of potatoes may be underestimated, but they are often not included in the healthiest vegetables. Potatoes contain important nutrients such as vitamins and a considerable amount of starch, which makes potatoes more energetic than most other vegetables. The results of the project have been published and can be accessed here:  https://matis.is/skyrsla/gaedi-og-andoxunarvirkni-graenmetis-a-markadi-2020-21/ . New results can be expected for vegetables in the coming months, including potatoes.

Matís holds a special course website where a variety of educational material is available. This is a website that hosts 7 courses, but each one addresses certain aspects that are important for small food producers to get acquainted with. The content of the courses is presented in a lively and practical way and can therefore also be useful for food production enthusiasts or curious entrepreneurs.

Small-scale food production in Iceland is, however, considerable and will probably increase in the coming years. Licensors and regulators demand to a much greater extent that manufacturers have the professional knowledge and experience to be able to produce safe and good products. The course material and course instructions allow those who intend to start small-scale food production to acquire knowledge that is useful, for example, in all kinds of raw material handling, storage and labeling of food, application for an operating license, internal control and the preparation of a quality manual.

The topics of the courses are as follows:

  • Licensing, quality manual, internal control and establishment of companies - Instructions for starting small-scale food production, distribution and sale.
  • Microorganisms on meat - Study materials and guidelines aimed at explaining the importance of proper processing and handling of food so that it does not cause harm.
  • Slaughter and meat eating - The meat assessment, ie. The classification of carcasses by sex, age, body fat and fat, plays an important role as a basis for pricing and trade in meat and for information for animal husbandry.
  • Salting and smoking - Taste properties and technical purpose of salting and smoking foods.
  • Food packaging labeling and packaging - All foodstuffs intended for end-users or commercial kitchens must be accompanied by food information in accordance with regulations. It can also be good to pack products in packaging and then it is important to know how to work.
  • Raw processing and sausage making - Educational materials on processed meat products, such as food that has been changed from its natural state in some way, mainly for safety reasons, to improve the taste quality or increase the comfort of consumption.
  • Sawing, deboning and marinating - Material on different divisions of an entire carcass into individual parts as well as marinating and the science behind it.

The educational material in the courses is compiled from various data, such as the laws and regulations that deal with food, from previous research and the study and promotional material that has been prepared at Matís and the Food Administration.

When purchasing a course, the study material opens and the buyer has access to it for 30 days.

Matís is the largest research company in the country in the field of food research and Matís' staff has many years of experience in food research. Great emphasis is placed on disseminating knowledge to the food industry in Iceland and web courses are one way to do this.
