Entomopathogenic fungi can associate with plants and influence plant defence mechanisms, promoting growth and affecting interactions among crops, herbivores and natural enemies. This study evaluated the effects of maize plant colonisation by Beauveria bassiana on direct and indirect plant defences. For this, we evaluated (i) the survival and reproductive biology of the stink bug Diceraeus melacanthus on seed-inoculated, foliar...

The double haploid (DH) technique in maize ( Zea mays L.) relies on in vivo haploid induction, in which the identification of haploid seeds and seedlings represents a critical step in this technique that determines the efficiency of DH line production. This study aimed to evaluate the effects of endosperm texture, donor genotype, and inducer on putative haploid rates based on the R1-navajo ( R1-nj ) marker and the use of guard...

Drosera regia , an endangered carnivorous plant endemic to South Africa, holds ornamental and pharmacological potential due to its distinctive morphology and bioactive metabolites. However, protocols for its in vitro propagation and genetic transformation remain scarce. This study establishes an integrated biotechnological approach for clonal propagation, acclimatization, adventitious regeneration, and Rhizobium radiobacter -m...

Background and aims In highly weathered soils of central Amazonia, where nutrients such as phosphorus (P) and base cations are scarce, fertilization experiments have demonstrated above- and belowground effects on total net primary productivity (NPP). This study examined how fine root stocks and turnover responded to added nutrients over a two-year period. We predicted that adding a limiting nutrient would decrease fine root st...
