Selective breeding for sterile sugar kelp
Growing seaweeds as a solution to our modern-day challenges is a hot topic. Seaweeds capture a lot of carbon and can provide us with nutritious food and biomaterials, while no land, freshwater and nutrients or pesticides are needed. Seaweed farming can, thus, be an interesting alternative for land-based agriculture. Providing seaweed farmers with the right seaweed seeding material is key in further developing the industry.
This research focuses on selective breeding for the seaweed ‘sugar kelp’. By making crosses with worldwide genetic varieties, we aim to produce a high-yielding and protein-rich sugar kelp cultivar that farmers can use. To prevent genetic material from distant locations spreading in the environment, we are also looking at creating sterile sugar kelp that does not produce any seeds; just like bananas and citrus fruits. In this way, we can harness the full potential of the genetic variation found in nature.
We are looking for HBO or university students with a great interest in seaweed (or plant) physiology and morphology and/or cell biology. As a (graduation) intern you will be experimenting with a wide range of sugar kelp crosses and compare them for their performance. We are trying to link their performance during all life stages to come up with early indicators for good performance. This means you will be busy with both lab work as well as tank experiments. A basic understanding of seaweed biology and basic lab skills are a plus. The work will primarily take place at NIOZ-Yerseke. A minimum internship period of 4 months is required. A guesthouse within walking distance from the institute is available.
