The causal agent of chayote (Sechium edule) powdery mildew (PM) was identified in Brazil. Microscopic examinations revealed hyaline and ovoid conidia, borne in chains and displaying distinctive extra-vacuolar fibrosin bodies. Morphology agreed to the standard description of the anamorph of Podosphaera xanthii. To confirm this identification, genomic DNA was extracted from field isolates and used in PCR assays with ITS primers. Amplicons were Sanger-sequenced and the nucleotide alignments of all isolates displayed identity levels above 97% with P. xanthii isolates in GenBank database. Phylogenetic analyses indicated only P. xanthii isolates as the PM-inducing pathogens in chayote. Inoculation assays were performed using chayote, zucchini and a set of muskmelon differential cultigens for determination of the physiological races of P. xanthii. All chayote isolates were pathogenic to chayote and zucchini seedlings. Five isolates were also pathogenic to the muskmelon cultigens ?Hale's Best Jumbo?, ?Védrantais?, ?PMR-45? and ?Edisto 47?, whereas ?PMR-5? was asymptomatic during the experimental period. The virulence profile of chayote-infecting isolates allowed their classification as P. xanthii race 2. To the best of our knowledge, this is the first worldwide report of P. xanthii race 2 in chayote. This report has relevant epidemiological and disease management implications, allowing more sustainable chayote cultivation under tropical and subtropical conditions. |

Abstract: We evaluated the influence of the substitution of soybean meal by detoxified castor cake on performance, digestibility of nutrients, nitrogen balance, hepatic and renal functions of pregnant goats fed with diets containing detoxified castor cake by alkaline solutions during the stages (first two-thirds and final third) of pregnancy. Three diets were provided: one based on soybean meal and the other two based on castor cake detoxified with whit calcium hydroxide or sodium hydroxide. Goats fed detoxified castor cake sodium hydroxide had lower consumption. Was no effect (P>0.05) of diets or stages on the digestibility of dry matter and nutrients. The goats that received the diets based on soybean meal and detoxified castor cake calcium hydroxide consumed larger amounts of nitrogen. The goats fed with diet the basis of SM had greater weight in the parturition day. The average levels of enzymes for hepatic and renal functions were within normal patterns. Of enzymes related to liver metabolism, only the gamma-glutamyl transferase increased in the final third of pregnancy. The present study demonstrated that detoxified castor by sodium hydroxide reduces the consumption of goats during gestation, but did not affect negatively the renal and hepatic parameters. |
