Recently, a group of scientists, successfully developed a new high-yielding transgenic desi chickpea variety. For that, they used the chickpea cytokinin oxidase/dehydrogenase gene expressed under the chickpea WRKY31 gene promoter.
The discovery of a pH switch in Arabidopsis is remarkable for understanding the plant’s response to pH and pH-dependent nutrient limitations. This study marks an important step forward in the search for pH sensors in plants, and sets the stage for applied research in the near future.
Considering the importance of these nutritious small grain crops the U.N. General Assembly recently adopted a resolution, sponsored by India and supported by more than 70 countries, declaring year 2023 as the International Year of Millets. The resolution is meant to extend public awareness on the health edges of millets and their suitableness for cultivation beneath robust conditions marked by global climate change.
Linseed or flax (Linum usitatissimum) is known to be one of the oldest crops, cultivated since the beginning of civilization. In the last two decades, due to the potential health benefits associated with its biologically active components, linseed has been the focus of increased interest in the field of diet and disease research.
Small to moderate amounts of caffeine can lift your moods and drop the stress levels. Caffeine (trimethylxanthine) is nothing, but a modified form of a related molecule called xanthine, which can also be converted into other smaller molecules that help the plants cope with stress. Of course, the kind of stress that the plants feel is different and more defined than that from human. For example, the most prominent stress in the plants is the lack of sufficient water. Hence, in a way, the content of xanthine in the plants can contribute to lifting the mood of the plants.
Commentary on Gobert et al. The authors prove the feasibility of an idea through this proof-of-concept work. As they point out, plant antiviral treatments are usually virus-specific, unfortunately for the moment a ‘broad-spectrum’ plant antiviral does not exist.
Grapevine (Vitis vinifera L.) is a crop of great economic and agricultural value throughout the world. In 2019, the International Organisation of Vine and Wine (OIV) reported that over 7 million hectares are dedicated to the cultivation of this crop, resulting in the global production of about 78 million tonnes of grape and 292 million of hectolitres of wine. However, a production of this magnitude is possible thanks to the massive use of pesticides to counteract various diseases that can affect grape yield. Indeed, pesticide applications are at the basis of intensive agriculture, as they guarantee protection from pathogens, pests and weeds. In absence of pesticide applications, farmers could experience up to 40% of production losses in a single year.
The effective management of plant diseases is of fundamental importance for forestry, food, and other plant-derived product productions, as well as for the sustainability of natural environments. Changing global climate patterns and the trade of planting materials across the borders are causing plant pathogens to rapidly move and evolve. That is plant pathogens, are changing their behavior, survival, reproduction, and mode of action in the host plants.
How do plants sense their environment? How do they cope with different challenges, like competition for resources or pest attacks? In a new study researchers explain the role of ST2a, a gene up-regulated by plant proximity cues, which participates in the inactivation of jasmonates –a group of regulators that orchestrate defense responses. This way they manage to demonstrate how competition signals promote plant growth at the expense of reduced defenses.
