Overcoming barriers to bioengineering new disease resistance

Bentham, De la Concepcion et al. fine-tuned a plant immune receptor pair to allow for engineering new specificities while avoiding autoactivation. https://doi.org/10.1093/plcell/koad204 Adam R Bentham, Mark J Banfield Department of Biochemistry and Metabolism, John Innes Centre, Norwich Research…

Review: Climate change impacts on plant pathogens, food security, and paths forward

Much of what is written about the impacts of climate change on food production is focused on the abiotic stresses that plants will experience, but biotic stresses will be equally impactful, as discussed in this fine review by Singh et al. The challenges in predicting climate impacts on plant disease…

Review: One plant’s poison

Plants synthesize interesting chemicals that attract, deter, amuse, and harm their predators. Some of the most harmful to humans have been selectively eliminated through the process of domestication, but others render potential food sources inedible. This review by Liu et al. discusses four approaches…

Extensive genome study to boost yield and improve agronomic traits in chickpea (Nature)

In recent years, there has been increasing awareness about the environmental impact of animal-based protein sources. Legumes such as chickpea (Cicer arientinum) are relatively cheap and sustainable sources of proteins, dietary fibres and micronutrients. Although there is a vast chickpea germplasm collection,…

Review: Orphan crops and their wild relatives in the genomic era (Mol. Plant)

More than half of human calories come from rice, wheat, and corn, although many other cereals have been domesticated as food crops. Several of these “orphan” cereal crops and their wild relatives are being studied with the goal of diversifying our food supply, which is particularly important due…

Review: The genetic basis and nutritional benefits of pigmented rice (Frontiers Genetics)

Pigmented rice varieties are those in which a pigment is deposited in the bran, the outer layer of the grain. The pigment can be from brown to red (proanthocyanidins) or from purple to black (anthocyanins). In the course of domestication, humans have selected against the genetic factors responsible for…

Opinion. Anthropogenic seed dispersal: Rethinking the origins of plant domestication (Trends Plant Sci)

Studies regarding the development of agriculture have started to integrate a plant evolutionary perspective. In this context, Spengler explores how changes in seed dispersal allowed plant domestication during the first half of the Holocene (e.g., more than 5000 years ago). He starts by redefining domestication…

From population to production: 50 years of scientific literature on how to feed the world (Global Food Security)

Tamburino et al. analyzed text from more than 12,000 research articles published in the past 50 years that included the terms “global” or “world” and “food supply”, “food demand’, or “zero hunger”. From this dataset, they quantified terms related to population, total food production,…

Review: The impact of synthetic biology for future agriculture and nutrition

The synthetic biology field is going to be important for the decade we began in order to face climate challenges, including food security. However, plant synthetic biology lags behind bacterial and other eukaryotic systems. Roell and Zurbriggen summarize in this review, many of the projects that are…
