Spontaneous plants of Ipomoea acuminata ("morning glory") exhibiting white rust pustules were found in a field crop area of Planaltina, DF, in the fall season of 2010 and the disease causal agent was identified as Albugo ipomoea-panduratae (Oomycota). No reports of the association between A. ipomoea-panduratae and I. acuminata were known in Brazil previously to 2010. A reference specimen was de...

To elucidate the genetic diversity of ten Ipomoea species, seed proteins were analyzed by SDS-PAGE and RAPD analysis. According to SDS-PAGE analysis, in total 51 different bands were identified across the studied species. The number of bands varies from 16 bands in Ipomoea cairica, to 3 bands in I. sinensis. The similarity analysis based on the SDS-PAGE profile turned out to be a useful charact...

Several auxin herbicides, such as 2, 4-D and dicamba, have been used to eradicate an exotic invasive weed Ipomoea cairica in subtropical China, but restraining the re-explosion of this weed is still a challenge. Since ethylene is one of the major intermediate functioning products during the eradication process, we explored the possibility, mechanism and efficiency of using ethephon which can re...

Viral diseases occur wherever sweet potato (Ipomoea batatas) is cultivated and because this crop is vegetatively propagated, accumulation and perpetuation of viruses can become a major constraint for production. Up to 90% reductions in yield have been reported in association with viral infections. About 20 officially accepted or tentative virus species have been found in sweet potato and other ...
