Repeatability and Heritability of UAV-Derived Canopy Traits in a Cassava Breeding Population Using Time-Series Data from Two Consecutive Growing Seasons

Cassava is a major staple crop in tropical regions, particularly in Sub-Saharan Africa, yet its productivity remains constrained by genetic and agronomic limitations. A major bottleneck in cassava breeding is the difficulty of accurately phenotyping agronomic traits under field conditions using conventional, labor-intensive methods. Here, we evaluated the potential of uncrewed aerial vehicle (UAV)-based phenotyping to quantify canopy growth traits and assess their genetic relevance under...

Multiple approaches for CRISPR-based targeting of DNA methylation to promoters of bacterial and viral susceptibility genes in cassava

Targeted epigenetic modifications of specific gene regulatory regions have the potential to confer beneficial traits for crop improvement. Two recently developed CRISPR/Cas9-based epigenome editing tools were tested in transgenic cassava to target cytosine methylation to the promoter region of MeSWEET10a, a necessary gene for infection by the Cassava bacterial blight pathogen, Xanthomonas phaseoli pv. manihotis. The two systems leverage unique methyltransferases, and each induced distinct...

For gluten-free food, look to other cultures around the world | Letters

Kathryn Monk says nutritious, naturally gluten-free food is widespread in cuisines of Africa, Asia, the Middle East and South America Your article on the rising cost of gluten-free foods highlights a genuine problem (Gluten-free basics ‘now a luxury’ as price of a small branded loaf nears £4, 30 May). However, I was struck by how narrowly the discussion was framed. Much of the article focuses on the affordability and availability of gluten-free versions of bread, biscuits, breakfast cereals...

The Romance Scammer Who Made a Small Fortune Posing as a WWE Superstar

For the first edition of WIRED Book Club, we've chosen Carlos Barragán’s The Yahoo Boys: Love, Deception, and the Real Lives of Nigeria’s Romance Scammers. Barragán took an old-school shoe-leather approach to a very online subject, flying to Lagos to embed himself with a group of young, desperate grifters. The account he brings back is a funny, sad, enraging read about how the internet can fuel heartbreak.
