Abstract:
... Cassava whitefly are a group of cryptic species within the Bemisia tabaci sensu lato complex that causes significant damage to cassava in Africa. B. tabaci Sub-Saharan Africa 1 (SSA1) is the major species in the study region which transmits plant-virus diseases to cassava and causes direct feeding damage. Benefits from management of cassava viral diseases through deployment of resistant varieties ...

Abstract:
... In Brazil, Pratylenchus brachyurus damages economic important crops and it is managed with non-chemical methods such as crop rotation or resistant cultivars. However, the variability in reproduction and damaging effects observed among P. brachyurus populations could limit the efficacy and long lasting effect of nematode control practices. Twelve populations of P. brachyurus from different geograph ...

Abstract:
... Foliar and fruit spots were observed on pomegranate trees (Punica granatum L.) in orchards at Balm and Zolfo Springs, FL, in 2019. Symptoms on leaves and fruits included dark brown to black irregular spots, 0.2 to 1.5 cm, with gray centers. Visible pycnidia were in the center of the lesions. Leaves became chlorotic and prematurely dropped. In a survey of 24 pomegranate cultivars, all trees were in ...

Abstract:
... The origins of cultivated chrysanthemums have attracted considerable attention, but they remain poorly known. Here, we reconstructed the phylogeny of representative well‐known cultivars and wild species of the genus Chrysanthemum using chloroplast genomes and the nuclear LEAFY gene. Our results suggest that geographic and ecological factors may determine the opportunities for wild species to be in ...

Abstract:
... Currently, in Brazil, part of the cucumber production is cultivated in greenhouses, in rotation with bell pepper and tomato. However, this kind of cultivation seems to be contributing to heavy infestations of Bemisia tabaci Mediterranean cryptic species (MED) in cucumbers, which is indeed related to the recent detection of tomato chlorosis virus (ToCV) in this crop. Thus, the present study investi ...

Abstract:
... BACKGROUND: While plant glucosinolates are known to impart resistance to many insects, their role in the interactions between plants and many phloem‐feeding insects such as whiteflies are poorly understood. The whitefly Bemisia tabaci complex comprises many cryptic species that differ in the ability to utilize Brassica plants. However, whether Brassica plants‐specific traits such as glucosinolates ...

Abstract:
... Fungus‐farming ants (Hymenoptera: Formicidae) have become model systems for exploring questions regarding the evolution of symbiosis. However, robust phylogenetic studies of both the ant agriculturalists and their fungal cultivars are necessary for addressing whether or not observed ant–fungus associations are the result of coevolution and, if so, whether that coevolution has been strict or diffus ...

In the marine crop Pyropia yezoensis, a cross-fertilization experiment between a cultivated strain and cryptic species was carried out to investigate the possibility of polyploidy breeding using cryptic species. To perform the cross-fertilization, we isolated a green mutant strain (IBYC-G1) of the cryptic species by heavy-ion beam irradiation. The green mutant was crossed with a wildtype strain (H ...

Abstract:
... Wheat blast caused by the Triticum pathotype of Pyricularia oryzae poses a serious threat to wheat production in South America and Asia and is now becoming a pandemic disease. Here, we show that Rmg8, a promising wheat gene for resistance breeding, is suppressed by PWT4, an effector gene of P. oryzae, and in turn that the suppression is counteracted by Rwt4, a wheat gene recognizing PWT4. When PWT ...
