Gene required for root hair growth, nitrate foraging found in grasses

By | News, Plant Science

Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed “BUZZ,” causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.

Unlocking the Genetic Code of Peppers: New Study Reveals Insights into Domestication and Diversity

By | Agriculture, News

Peppers are a versatile, flavorful, and widely popular crop, used not only as a healthy food source but also for their medicinal properties. In a new study, an international team of researchers has sequenced the genomes of key cultivated and wild pepper species, offering unprecedented insights into pepper evolution, domestication, and genetic diversity.

Optimizing cacao pollination for higher yields

By | Agriculture, News

The success of cacao cultivation depends to a large extent on functioning pollination. If there is a lack of pollinators, for example, this leads to lower yields – and thus to financial problems for farmers. A study has now investigated how the yield and quality of organic cacao can be increased – through a more efficient plantation design that’s taking ecological aspects into account. During research in Peru, the researchers identified pollination techniques that improved pollination success and produced higher quality fruit.

Researchers Study Salt Tolerance of Wild Grapevine to Make Crops More Resilient

By | Agriculture, Fruits and Vegetables, News

Rising sea levels due to climate change and artificial irrigation cause soil salinity to increase. This has a negative impact on agriculture, including viticulture. The plants die, yields decrease. Researchers have therefore studied a wild grapevine of higher salt tolerance. Their goal is to identify the genetic factors that make the grapevine resilient. They can then be inserted into commercial varieties, thus securing viticulture.

Disease-resistant plants may modulate disease susceptibility in their neighbors

By | Agriculture, News, Plant Science

Researchers discovered a form of social immunity in wheat and rice. Disease susceptibility in wheat and rice is modulated not only by genetic resistance traits, but also by interactions with neighbouring plants of the same species. The findings, show that inter-plant cooperation can reduce disease susceptibility by nearly 90 percent in certain cases, as much as is conferred by a plant’s own resistance genes. The findings create new possibilities for improving plant resistance to disease and reducing the use of pesticides.

You say tomato, these scientists say evolutionary mystery

By | Agriculture, Fruits and Vegetables, News

Biologists have found evidence for evolutionary “syndromes”—sets of traits that occur together—that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research, not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.
