In eukaryotes, histone acetylation and methylation have been known to be involved in regulating diverse developmental processes and plant defense. These histone modification events are controlled by a series of histone modification gene families. To date, there is no study regarding genome-wide characterization of histone modification related genes in citrus species. Based on the two recent seq...

Citrus canker is a quarantined disease caused by the bacterial plant pathogen Xanthomonas citri subsp. (Xcc), which causes persistent surface damage, leaf and fruit drop, tree decline in citrus plants. The cultivar Citron C-05 (Citrus medica L.) disease-resistant genotype identified after years of screening at National Center for Improvement (Changsha), displays allergic, necrotic, responses to...

ABSTRACT Vitamin A deficiency is common in developing countries. Sweet potato can be an ally reversing this situation since it has a low acquisition cost and high market availability. In addition, some genotypes have orange-flesh roots, rich beta-carotene, which the precursor of vitamin A. Thus, objective research was to select orange-fleshed sweet using two selection indices (Smith Hazel Mulam...

Background: Mosquitoes transmit severe diseases such as malaria, lymphatic filariasis, dengue fever, and yellow fever. These result in significant morbidity mortality humans around the world. This study aimed to provide information on larvicidal potential of different Citrus species peels against Culex mosquito larvae.Methods: Ethanol extracts four species, sinensis (sweet orange), reticulata (...

The purposes of this study were to assess the effectiveness drought tolerance indices for selection in orange fleshed sweet potato genotypes. In order efficiency indices, 10 Orange Fleshed Sweet Potato genotypes (OFSP) evaluated under Normal or full irrigation and extreme water stress environments.

The alternative oxidase (AOX) protein is present in plants, fungi, protozoa and some invertebrates. It is involved in the mitochondrial respiratory chain, providing an alternative route for the transport of electrons, leading to the reduction of oxygen to form water. The present study aimed to characterize the family of AOX genes in mandarin (Citrus clementina) and sweet orange (Citrus sinensis...

We optimized RAPD techniques by increasing the length of RAPD primers and performing a strict screening of PCR annealing temperature to distinguish 60 sweet orange cultivars from the Research Institute of Pomology at the Chinese Academy of Agricultural Sciences. A new approach called cultivar identification diagram (CID) was used to improve the efficiency of RAPD markers for cultivar ident...

The spatial distribution of the three principal species of sharpshooter (Dilobopterus costalimai Young, Acrogonia sp. e Oncometopia facialis Signoret), vectors of Xylella fastidiosa causal agent of Citrus Variegated Chlorosis, was studied by using geostatistics. The evaluations were carried out in a commercial ‘Pera’ sweet orange (Citrus sinensis [L.] Osb.) grove budded on Rangpur lime (Citrus ...

introduction: citrus fruits, which belong to the family of rutaceae are one of the main fruit tree crops grown throughout the world. although sweet orange (citrus sinensis) is the major fruit in this group accounting for about 70% of citrus output.citrus fruits are well – appreciated fortheir refreshing juice and health benefits.the health benefits of citrus fruits are linked to the high amount...
