Researchers at the University of Gothenburg have developed several new varieties of wheat that tolerate soils with higher salt concentrations. After having mutated a wheat variety from Bangladesh, they now have a wheat with seeds that weigh three times more and that germinate almost twice as often as the original variety, writes the Swedish university in a press release<\/a>.<\/p>\n\n\n\n

The wheat, which grows in fields near the coast in Bangladesh, has a certain tolerance to salt in soils, which is important when more and more farmland around the world is being exposed to saltwater.<\/p>\n\n\n\n

By mutating the wheat seeds from these coastal fields, researchers at the University of Gothenburg were able to develop approximately 2,000 lines of wheat. The 35 lines that germinated the best at different field and lab experiments were planted in an automated greenhouse in Australia, where different saline concentrations were applied to the plants that were then weighed. They were photographed each day until the wheat had formed its ears. The findings were striking.<\/p>\n\n\n\n

Genes for salt tolerance identified<\/h3>\n\n\n\n

\u201cWe developed wheat lines where the average weight of the seeds was three times higher and that germinated more often than the original wheat from Bangladesh,\u201d says Johanna Lethin, a doctoral student at the Department of Biological and Environmental Sciences at the University of Gothenburg.<\/p>\n\n\n\n

Using DNA analyses and studies of other research, the team was also able to identify what genes control salt tolerance in the wheat plant.<\/p>\n\n\n\n

\u201cThis is a milestone in our research. Now we have a couple of genes we know are involved in salt tolerance. The next step is to test if these genes are also in our best wheat varieties that we have mutated into existence.\u201d<\/p>\n\n\n\n

2,000 hectares lost per day<\/h3>\n\n\n\n

The Earth\u2019s population is growing and in 2050, there will be 10 billion people on the planet who all need to be fed. At the same time, climate changes are causing the Earth\u2019s arable land to dry up and other areas to be flooded by rising seas. All this increases interest in a crop that can tolerate salt in soil.<\/p>\n\n\n\n

\u201cIt is incredibly important to try to develop a salt-tolerant variety with good yields. Currently, we are losing approximately 2,000 hectares a day to rising seas and improper irrigation methods that increase soil salinisation.\u201d<\/p>\n\n\n

Vertical farming<\/div>
From the outside, it may look just like your regular office building. But inside, the future of farming takes place. <\/div><\/div><\/div>\n\n\n

Global potential<\/h3>\n\n\n\n

Some experiments remain to do, but the potential in this discovery is global. Today, about 8 per cent of the world\u2019s arable land is no longer usable for crops because of salt contamination and more than half of the world\u2019s countries are affected. In Egypt, Kenya and Argentina, wheat cannot be grown on large areas and even low-lying areas of Europe, like the Netherlands, have these problems. Even in those parts of Asia where rice is currently the dominant crop, salt-tolerant wheat will become an important part of the future food supply since wheat farming requires much less water than rice.<\/p>\n\n\n\n

\u201cThe next stage is to plant the salt-tolerant varieties in fields in Bangladesh. I would estimate that it will take about five years before we can have commercial production of salt-tolerant wheat, depending on how the field tests go.\u201d<\/p>\n","protected":false},"author":2084,"featured_media":516181,"template":"","meta":{"_acf_changed":false,"advgb_blocks_editor_width":"","advgb_blocks_columns_visual_guide":""},"categories":[69111],"tags":[29526,4261,57454,127798],"location":[54353],"internal_archives":[],"class_list":["post-375463","selected","type-selected","status-publish","has-post-thumbnail","hentry","category-agrifood","tag-agriculture","tag-research","tag-university-of-gothenburg","tag-wheat","location-sweden"],"blocksy_meta":[],"acf":[],"featured_img":"https:\/\/ioplus.nl\/archive\/wp-content\/uploads\/2022\/05\/P3A1647-Panorama_v2_Low-crop-scaled.jpg","coauthors":[],"author_meta":{"author_link":"https:\/\/ioplus.nl\/archive\/author\/mauro-mereu\/","display_name":"Mauro Mereu"},"relative_dates":{"created":"Posted 4 years ago","modified":"Updated 4 years ago"},"absolute_dates":{"created":"Posted on May 23, 2022","modified":"Updated on May 23, 2022"},"absolute_dates_time":{"created":"Posted on May 23, 2022 11:00 am","modified":"Updated on May 23, 2022 11:00 am"},"featured_img_caption":"","tax_additional":{"category":{"linked":["Agrifood<\/a>"],"unlinked":["Agrifood<\/span>"],"slug":"category","name":"Categories"},"post_tag":{"linked":["agriculture<\/a>","research<\/a>","University of Gothenburg<\/a>","wheat<\/a>"],"unlinked":["agriculture<\/span>","research<\/span>","University of Gothenburg<\/span>","wheat<\/span>"],"slug":"post_tag","name":"Tags"},"language":{"linked":["EN<\/a>"],"unlinked":["EN<\/span>"],"slug":"language","name":"Tags"},"post_translations":{"linked":[],"unlinked":[],"slug":"post_translations","name":""},"location":{"linked":["Sweden<\/a>"],"unlinked":["Sweden<\/span>"],"slug":"location","name":"Locations"},"internal_archives":{"linked":[],"unlinked":[],"slug":"internal_archives","name":"Internal Archives"}},"series_order":"","_links":{"self":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected\/375463","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/selected"}],"about":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/types\/selected"}],"author":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/users\/2084"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media\/516181"}],"wp:attachment":[{"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/media?parent=375463"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/categories?post=375463"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/tags?post=375463"},{"taxonomy":"location","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/location?post=375463"},{"taxonomy":"internal_archives","embeddable":true,"href":"https:\/\/ioplus.nl\/archive\/wp-json\/wp\/v2\/internal_archives?post=375463"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
