“…Based on chloroplastic phylogeny, Bayer et al (2009) included Microcitrus and Eremocitrus within the group of True Citrus fruit trees (sensu Swingle and Reece, 1967), and proposed to include them in the genus Citrus following Mabberley (2004). The monophylly of the True Citrus species and the crosscompatibility between Oceanian and Asian citrus species are strong arguments sustaining this suggestion (Ollitrault et al, 2020). However, nuclear phylogeny clearly identified two sister clades within the True Citrus, one for the Asian species and the other for the Oceanian ones, with either full or partial resistance only present in the Oceanian clade (and observed for all Oceanian species tested).…”

Huanglongbing (HLB) is the most destructive, yet incurable disease of citrus. Finding sources of genetic resistance to HLB-associated ‘Candidatus Liberibacter asiaticus’ (Las) becomes strategic to warrant crop sustainability, but no resistant Citrus genotypes exist. Some Citrus relatives of the family Rutaceae, subfamily Aurantioideae, were described as full-resistant to Las, but they are phylogenetically far, thus incompatible with Citrus. Partial resistance was indicated for certain cross-compatible types. Moreover, other genotypes from subtribe Citrinae, sexually incompatible but graft-compatible with Citrus, may provide new rootstocks able to restrict bacterial titer in the canopy. Use of seedlings from monoembryonic species and inconsistencies in previous reports likely due to Las recalcitrance encouraged us to evaluate more accurately these Citrus relatives. We tested for Las resistance a diverse collection of graft-compatible Citrinae species using an aggressive and consistent challenge-inoculation and evaluation procedure. Most Citrinae species examined were either susceptible or partially resistant to Las. However, Eremocitrus glauca and Papua/New Guinea Microcitrus species as well as their hybrids and those with Citrus arose here for the first time as full-resistant, opening the way for using these underutilized genotypes as Las resistance sources in breeding programs or attempting using them directly as possible new Las-resistant Citrus rootstocks or interstocks.

“…Citrus is an important horticultural crop with a long life cycle, as is one of the most widely planted fruit trees in the world [ 1 ]. Citrus plants are mainly planted in mountains and hills, and they are extremely susceptible to biotic and abiotic stresses, such as high temperatures, droughts, cold, diseases, and pests, all of which reduce fruit quality and affect the development of the citrus industry [ 2 , 3 ].…”

Arbuscular mycorrhizal (AM) fungi and endophytic fungi collectively symbiose well with plants and, thus, stimulate plant growth; however, it is not clear whether field inoculation of the fungi enhances the resistance potential of plants, particularly in citrus. In the present study, we inoculated AM fungi (Acaulospora scrobiculata, Diversispora spurca, and D. versiformis) and endophytic fungi (Piriformospora indica) on an eight-year-old lane late navel orange (Citrus sinensis (L.) Osb) trees grafted on Poncirus trifoliata in a field, and we analyzed the response of the leaf antioxidant defense system. Approximately 2 years after inoculation, the root fungal colonization rate and soil hyphal length significantly increased. Fungal inoculation significantly increased the activity of leaf antioxidant enzymes, such as superoxide dismutase, peroxidase, catalase, and ascorbate peroxidase, and the content of non-enzymatic antioxidants, such as reduced ascorbic acid and reduced glutathione. As a result, fungi-inoculated plants maintained lower concentrations of hydrogen peroxide and superoxide anion radicals and lower levels of membrane lipid peroxidation (according to malondialdehyde level) in leaves than uninoculated plants. Among them, inoculation of D. spurca and A. scrobiculata showed relatively higher effects in enhancing the antioxidant defense system than the other fungi. Furthermore, inoculation of D. spurca induced expressions of CsFe-SOD, CsMn-SOD, CsPOD, CsCAT1, and CsPRR7; inoculation of A. scrobiculata and D. versiformis induced expressions of CsCAT1; CsCAT1 and CsPOD were also induced by inoculation of P. indica. All four inoculations almost upregulated expressions of CsFAD6. AM fungi had superior effects than endophytic fungi (e.g., P. indica). According to our findings, inoculation with beneficial fungi, specifically mycorrhizal fungus D. spurca, activated the antioxidant defense system of field citrus trees, thus, having potentially superior resistance in inoculated plants.

Abstract. Sofiyanti N, Iriani D, Wahyuni PI, Idani N, Lestari P. 2022. Identification, morphology of Citrus L. (Aurantioideae-Rutaceae Juss.) and its traditional uses in Riau Province, Indonesia. Biodiversitas 23: 1038-1047. The genus Citrus (Rutaceae) is an important fruit crop in the world. The species of Citrus are extensively cultivated for fresh fruit and processed juice market. In addition, Citrus members have a great ability to cross and produce intra or intergeneric hybrids. Therefore, the taxonomic identification of the cultivars has been a serious challenge for botanists and agronomists. In Riau Province (Indonesia), the cultivars of this genus are grown for various uses. The aims of this study are to identify Citrus taxa in Riau Province, examine their morphological characters, and document their uses by local people. Samples were collected in the field. The result shows a total of 18 Citrus members were identified in this study. The Citrus morphologies vary among the members. Each Citrus identified in this study shows its morphological characteristic of vegetative and generative parts. Numerous local uses of Citrus are recorded in this study, e.g. fresh consumed, traditional drink, folklore, herb, spice and ornamental. The parts of Citrus used are whole plant, leaf, pericarp and pulp. The uses of Citrus recorded in this study are for herb and spice, dessert, traditional drink and treatment, folklore, and ornamental plant. This study provides the first record of the morphological characteristic of Citrus in this province and the uses of its members.
