Citrus cropping is widely distributed as an important economic activity worldwide. Amongst the major producers are Brazil, China, United States, Mexico and some European countries. Brazil largest sweet orange producer accounting for more than three-quarters of juice exports around world, followed by China States (Foreign Agricultural Service/USDA, 2019). Although main commodity in many countries producing citrus, by-products like essential oils, molasses, dried pulp, pectin, blend syrup...
Citrus sudden death (CSD) has caused the of approximately four million orange trees in a very important citrus region Brazil. Although its etiology is still not completely clear, symptoms and distribution affected plants indicate viral disease. In search for viruses associated with CSD, we have performed comparative high-throughput sequencing analysis transcriptome small RNAs from CSD-symptomatic -asymptomatic using Illumina platform. The data revealed mixed infections that included tristeza...
Abstract Bacillus thuringiensis (Bt) toxins are effective in controlling insect pests either through the spraying of products or when expressed transgenic crops. The discovery endophytic Bt strains opened new perspectives for studies aimed at control sap‐sucking insects, such as Asian citrus psyllid Diaphorina citri Kuwayama (Hemiptera: Liviidae), a vector “ Candidatus Liberibacter spp.,” associated with huanglongbing (HLB). In this study, translocation seedlings inoculated suspension...
Citrus is the most important fruit crop in Brazil and tristeza virus (CTV) considered one of pathogens citrus. Most citrus species varieties are susceptible to CTV infection. However, Poncirus trifoliata, a close relative citrus, resistant virus. In order better understand responses plants infection CTV, we constructed expressed sequence tag (EST) libraries with tissues collected from trifoliata plants, inoculated or not at 90 days after inoculation, grafted on Rangpur lime rootstocks. We...
Citrus sudden death-associated virus (CSDaV) is a monopartite positive-sense single-stranded RNA that was suggested to be associated with citrus death (CSD) disease in Brazil. Here, we report the first study of genetic structure and molecular variability among 31 CSDaV isolates collected from both symptomatic asymptomatic trees CSD-affected areas. Analyses partial nucleotide sequences five domains genomic RNA, including those encoding for methyltransferase, multi-domain region (MDR),...
In order to obtain a better understanding of what is citrus, 33 cDNA libraries were constructed from different citrus species and genera. Total RNA was extracted fruits, leaves, flowers, bark, seeds roots, subjected or not biotic abiotic stresses (pathogens drought) at several developmental stages. To identify putative promoter sequences, as well molecular markers that could be useful for breeding programs, one shotgun library prepared sweet orange (Citrus sinensis var. Olimpia). addition,...
A produção mundial de citros tem sido afetada em função diversos estresses ambientais somados a problemas fitossanitários. Dentre as doenças, principal é o huanglongbing (HLB), que se estabelece forma rápida na cultura, afetando todas variedades comerciais citros, ou seja, não existe resistência conhecida dentro Citrus spp. Ademais, transmissão mediada por vetores eficiente. Em disso, vários grupos pesquisa ao redor do mundo têm buscado diferentes estratégias visando controle da doença,...
