Heat-Resistant Seeds Offer Restoration Lifeline in Brazil

“Fire-resistant seeds offer promise, at a low cost, for restoring areas devastated by burning in Brazil’s Cerrado savanna, a project by biologist Giovana Cavenaghi Guimarães shows.

Guimarães, a doctoral candidate at São Paulo State University (UNESP), focused on five species of Cerrado-native seeds, including jatobá (Hymenaea courbaril), amendoim-bravo (Pterogyne nitens), mulungu (Erythrina mulungu) and canafístula (Peltophorum dubium). All are naturally adapted to extreme heat.

According to Guimarães, these plants can survive in adverse conditions such as the high temperatures caused by wildfires, which makes their seeds ideal for environmental recovery after such events. The species also have a greater germination capacity: on average, 99% of seeds develop into trees…

According to Guimarães, planting seeds of these native fire-resistant species can be a solution to recover large areas destroyed by wildfires, especially in the Cerrado, the Brazilian biome that burns the most. Data from INPE, Brazil’s national space agency, showed 46.8% of all fire outbreaks recorded in the country in the first 10 months of the year — almost 50,000 — occurred in the Cerrado.”

Novel Wheat Hybrids Increase Fungal Disease Resistance

“A new experimental study has identified a novel genetic locus in a common agricultural weed, Elymus repens, that provides significant resistance to the destructive fungal disease Fusarium Head Blight (FHB) and has now been successfully transferred into wheat to produce FHB resistant hybrids…

Dr. Yinghui Li and Houyang Kang’s research team’s new study, published in the Journal of Experimental Botany, outlines how they successfully hybridized E. repens and cultivated wheat to transfer FHB-resistant genes from E. repens into the wheat.

When testing for the presence of FHB from deliberately infected plants, hybrid genotypes containing the resistance genes, labeled as 1StL, showed a 69% reduction in diseased plant spikelets under greenhouse conditions compared to the control wheat, and a 60% reduction under field conditions.”

Banana, the Crop That Defeated a Food Crisis in Tanzania

“In Tanzania, nearly half of banana farmers in Kagera have adopted improved varieties introduced through a partnership led by ENABEL and KU Leuven, with CGIAR playing a crucial role in their selection and dissemination, helping secure food and livelihoods for over 125,000 people in the region…

An impact study by IITA reveals the scale of the transformation. By 2024, nearly 48% of banana farmers in Kagera had adopted these improved varieties, leading to 15% increase in productivity, reduced crop losses from pests and diseases and more farmers producing surplus for markets.

For households, this translates directly into better nutrition. Daily caloric intake among adopting families increased by 27%, reflecting improved food availability and diversity.

The impact extends beyond the farm.

As production increased, so did economic opportunities across the banana value chain. Traders expanded into larger and more distant markets, while processors began favoring the improved varieties for cooking and dessert, and better processing qualities. The region’s economy benefited from an estimated 119,000 additional tons of banana production annually, contributing nearly $7 million per year.”

California Salmon Population Rebounds, Fishing Open Again

“Federal fishery managers voted Sunday to open waters off the coast of California to commercial salmon fishing for the first time since 2022, with the population rebounding after wet winters ended a long drought.

The decision by the Pacific Fishery Management Council to allow limited commercial and recreational salmon fishing off the coast is a win for the state’s salmon fishing industry, which has grappled with years of season closures due to dwindling fish stocks. The council, which manages fisheries off the West Coast, barred commercial salmon fishing off California for the past three years. It voted last year to allow some recreational fishing for the first time since 2022.”

World’s First Non‑Browning Bananas

“Tropic, the pioneering agricultural biotechnology company, has secured regulatory approval in both Japan and Brazil for its world first non‑browning banana variety, unlocking two of the most important fresh‑produce markets globally and marking a significant milestone in the future of sustainable fruit production.

The approvals clear the way for Tropic’s non‑browning banana to be imported, sold, and consumed in both countries, and grown in Brazil – enabling expanded consumer access, new commercial opportunities, and substantial reductions in global food waste.”
