Plants face constant attack by diseases, insect swarms, and fungi, resulting in crop losses that threaten global food security. Discovering new ways to help the plant defend itself against attack is an enormous challenge for scientists.
Strawberry losses from Fusarium wilt could become less of a threat after researchers discovered genes that are resistant to the deadly soil-borne disease.
Scientists have discovered how to design cereal roots able to continue growing in hard soils by altering their ability to penetrate, enabling roots to access sources of water deeper in soil, and helping ‘climate-proof’ vital crops in response to changing rain fall patterns.
Host-killing by hemiepiphytes is an endemic phenomenon in the tropics. Many fig species—keystone plants in tropical forests—have evolved the hemiepiphytic ecotype. However, the benefits and adaptive strategies of their special life history remain poorly understood.
Increased demand for water will be the No. 1 threat to food security in the next 20 years, followed closely by heat waves, droughts, income inequality and political instability, according to a new study which calls for increased collaboration to build a more resilient global food supply.
The effects of drought on major crops that are crucial to achieve both food and energy security. A global, more robust vision of this complex issue to advance the existing knowledge and support better informed, science-based decisions in the future, like fine-tuning crop calendars or implementing other measures as alternative cultivars, additional irrigation, and crop migration.
International research team aims to significantly reduce the threat of cassava mosaic disease and improve cassava yields, an important crop in the tropics.
Research could allow agriculturists to optimize productivity and explore the viability of ‘virgin fruits’
Plant growth is not a uniform process: Plants grow in length at the shoot and root tip in particular, while in other places they form new leaves or flowers. These different processes must be coordinated with each another and at the same time react to external influences such as temperature and light. Scientists discover previously unknown mechanism that regulates the growth hormone auxin.
Like humans and animals, plants also have a microbiota. A research team studied whether the genetic variability within a plant species controls the composition of its leaf microbiota. The researchers planted more than 30,000 plants in experimental set-ups at four sites over two years to analyse variation in the leaf microbiota and reproductive success, estimated through seed production, of 200 genotypes of a model plant. Their results, show that genetic variation between plants has a particular impact on specific microorganisms, which in turn have a strong influence on the composition of microbial communities. This influence on microbial communities contributes to the reproductive success of different plant genotypes.
