Citrus breeding programs have many limitations associated with the species biology and physiology, requiring incorporation of new biotechnological tools to provide possibilities. Diversity Arrays Technology (DArT) markers, combined next-generation sequencing, wide applicability in construction high-resolution genetic maps quantitative trait locus (QTL) mapping. This study aimed construct an integrated map using full-sib progeny derived from Murcott tangor Pera sweet orange DArTseq™ molecular...
Abstract Huanglongbing (HLB), caused mainly by ‘ Candidatus Liberibacter asiaticus’ (CLas), is the most devastating citrus disease because all commercial species are susceptible. HLB tolerance has been observed in Poncirus trifoliata and their hybrids. A wide-ranging transcriptomic analysis using contrasting genotypes regarding severity was performed to identify genetic mechanism associated with HLB. The included Citrus sinensis, sunki, three distinct groups of hybrids obtained from crosses...
The Citrus sinensis LATERAL ORGAN BOUNDERIES 1 (CsLOB1) gene, which is directly induced by the Xanthomonas citri subsp. effector PthA4, functions as a transcription factor and citrus canker susceptibility (S) gene. Genome editing of CsLOB1 has been shown to confer resistance disease. Previous studies revealed that CsLOB1-INDUCED EXPANSIN gene (CsLIEXP1) highly upregulated in citri-infected plants. Because expansins are associated with cell wall loosening, potentially facilitating bacterial...
Phytophthora nicotianae Breda de Haan (Phytophthora parasitica Dastur) causes severe damage to citrus crops worldwide. A population of citrandarins was created from the cross between susceptible parent Citrus sunki Hort. Ex Tan. and resistant Poncirus trifoliata (L.) Raf. cv. Rubidoux, both parents two reference rootstocks (Rangpur lime Swingle citrumelo) were grafted in a greenhouse on Rangpur lime. Inoculations performed at 10 cm 15 above grafting region resulting lesions evaluated by...
The symptoms of huanglongbing (HLB), a disease caused by the bacterium Candidatus Liberibacter asiaticus (CLas), are visible on canopy citrus plants. They include mottling leaves followed dropping and lopsided fruits with premature dropping. Loss in phloem functionality degradation root system also HLB severe impact plant growth production. Some Citrus relatives, such as Poncirus trifoliata its hybrids, have shown more tolerance to low titers CLas compared species, but little is known about...
Citrus plants have been extremely affected by Huanglongbing (HLB) worldwide, causing economic losses. HLB disease causes disorders in citrus plants, leading to callose deposition the phloem vessel sieve plates. Callose is synthesized synthases, which are encoded 12 genes (calS1- calS12)in Arabidopsis thaliana. We evaluated expression of eight synthase from hybrids between sunki and Poncirus trifoliata infected with HLB. The objective this work was identify possible tolerance loci combining...
Citrus orchards have some limitations, such as the occurrence of phytosanitary problems. Alternaria brown spot (ABS) is caused by fungus alternata, which affects several parts plant producing a host-specific toxin, known ACT. ABS limiting factor in due to susceptibility most planted cultivars: ‘Murcott’ tangor and ‘Ponkan’ tangerine. The selection varieties resistant/tolerant disease has economic importance. Therefore, aim this experiment was evaluate response A. alternata inoculation...
Background: Huanglongbing (HLB) is currently one of the most devasting diseases in citrus plants worldwide. Resistance against its causal agent, Candidatus Liberibacter asiaticus (CLas), commercial Citrus species remains a challenge, even though they show differences CLas multiplication. Methods: A total 14 citrandarins and their parents (Sunki mandarin Poncirus trifoliata cv. Rubidoux) were top-grafted onto canopy potted ‘Valencia’ sweet orange with high titers. The grafted genotypes tested...
Huanglongbing (HLB) is currently one of the most important diseases in citrus plants worldwide. Resistance against its causal agent, Candidatus Liberibacter asiaticus (CLas), commercial Citrus species within subtribe Citrinae a challenge, even though multiplication CLas differs among species. For this paper, we selected 14 citrandarin hybrids obtained from crosses involving parents Sunki mandarin and Poncirus trifoliata tested them for infection disease effects. These were considered...
Abstract The Citrus Breeding Program of the Citriculture Center at Agronomic Institute (IAC) has developed a mandarin cultivar IAC 2019Maria from crossing between Murcott tangor (Citrus reticulata x sinensis) and Pera sweet orange (C. sinensis). present study aimed to assess number seeds in fruits identify zygotic embryos triploid plants crossings mandarin, orange, Ponkan Blanco), addition open self-pollination. flowers were self-pollinated, pollinated with pollen had no pollination....
