- ... Phymatotrichopsis omnivora, the causal pathogen of cotton root rot, is a devastating ascomycete that affects numerous important dicotyledonous plants grown in the southwestern United States and northern Mexico. P. omnivora is notoriously difficult to isolate from infected plants; therefore methods for accurate and sensitive detection directly from symptomatic and asymptomatic plant samples are nee ...

- ... Over 3 yr, spring-calving beef cows (n = 108, yr 1; n = 72, yr 2 and 3; initial fall BW = 480 ± 8.6 kg, BCS = 5.5 ± 0.07; age = 6 ± 2.6 yr) were allocated by parity, breed composition, and BW to 4.8 ha (n = 6) of warm-season pastures and limit grazed 2.4 ha of tall fescue (Festuca arundinacea) during the winter and spring to determine the effect of endophyte toxicity or clover additions on cow per ...

- ... The gene cluster required for paxilline biosynthesis in Penicillium paxilli contains two cytochrome P450 monooxygenase genes, paxP and paxQ. The primary sequences of both proteins are very similar to those of proposed cytochrome P450 monooxygenases from other filamentous fungi, and contain several conserved motifs, including that for a haem-binding site. Alignment of these sequences with mammalian ...
