The oxidation of fatty acids, which is responsible for changes in lipid composition, were investigated in a comparative study using the Russian wheat aphid (RWA) (Diuraphis noxia), infested and un-infested resistant (Tugela DN) and close isogenic-sus

The Russian wheat aphid (RWA) is serious pest of wheat in South Africa since its discovery in 1978. Nitric oxide (NO) plays an essential role in the RWA resistance response of wheat. This study was conducted to establish whether NO acts upstream or d

Activities of potential reactive oxygen species generating enzymes and the subsequent production of H2O2, were investigated during the rust (Puccinia helianthi)—sunflower interaction using resistant (PhRR3) and susceptible (S37–388) lines. The re

The potential to control leaf rust (Puccinia triticina; pathotype UVPt9) in vivo in susceptible (Thatcher) and resistant (Thatcher/Lr15) near-isogenic wheat (Triticum aestivum) lines by foliar applications of crude plant leaf extracts from Tulbaghia

To investigate the role of β-1,3-glucanases (EC 3.2.1.39) and chitinases (EC 3.2.1.14) in the resistance response of wheat (Triticum aestivum L.) to leaf rust (Puccinia recondita f. sp. tritici), their intercellular activities were studied in resist
