Description
Filipe R Valeriano leads a ten-author team comparing in 2026 how three Brazilian blackberry varieties withstand a rust fungus that invades their leaves. Blackberry growing supports family farms in Brazil, and the fungus Kuehneola uredinis colonizes the leaf's middle layer, swelling cells before bursting through the surface to release spores. Microscopy and chemical staining compared healthy and infected tissue across the cultivars.
Guarani answered invasion with vigorous tissue expansion, thickening its leaf blade and upper skin. BRS Xavante suffered the worst structural losses, losing nearly half the thickness of its light-catching cell layer. BRS Tupy held its anatomy steadiest, looking the most tolerant. Infected zones everywhere accumulated defensive phenolics, proteins, and oils, although the weakest cultivar made fewer protective oils. Breeders, the authors say, now know which parent stock to favor.
