“…InDel markers were discovered in a number of Citrus species [32]. It is difficult to assess how these genetic markers relate to physical and chemical characteristics [33]; hence, these markers might not explain variations in flavor profiles. In a recent study, a neighbor-joining method served to explain the diversity of Citrus.…”

Citrus, belonging to the Rutaceae family, is a commercial fruit worldwide, and it is mainly recognized for its nutritional, anti-oxidant, and significant medicinal properties. Citruses are a group of multifaceted fruit crops with a rich traditional knowledge, deeply rooted in ethnic culture, and the fruits have been considered to be health-protecting and health-promoting food supplements since ancient times. The presence of secondary metabolites and their bioactivities has led to the development of new alternative drugs in recent years. Diverse secondary metabolites such as flavonoids, alkaloids, carotenoids, phenolic acids, and essential oils and their high bioactive properties have imparted great value to human health based on their anti-oxidative, anti-inflammatory, anti-cancer, cardiovascular protective, and neuroprotective effects. The indigenous Citrus species of India—mainly Northeast India—have distinctive and valuable genetic traits, such as resistance to biotic and abiotic stress, distinctive aroma, flavor, etc. Hence, these species are considered to be repertoires of valuable genes for molecular breeding aimed at quality improvement. There is a need for awareness and understanding among the citrus-producing countries of the exploitation of biodiversity and the conservation of Citrus for sustainable development and bioprospecting. The current review presents a holistic view of Citrus biodiversity from a global perspective, including phytochemical constituents and health benefits. Advanced biotechnological and genomic approaches for Citrus trait improvement have also been discussed to highlight their relevance in Citrus improvement.

“…Many indigenous citrus cultivars are known to originate from natural hybrids. Their parentage has been identified using molecular makers developed on the basis of organelle and nuclear genome sequences (Shimizu et al, 2016;Woo et al, 2020;Kim et al, 2021;Yi et al, 2021). In this study, we hypothesized that yuzu might have originated from natural hybridization between Ichang papeda and mandarin based on sequence analyses of chloroplast genomes and nuclear genes.…”

Yuzu (Citrus junos Sieb. Ex Tanaka) is one of the most important Citrus species in China, Japan, and Korea. Yuzu is assumed to be a natural hybrid. However, concrete evidence supporting its hybrid origin has not been reported yet. To identify putative maternal species, the nucleotide sequences of five hypervariable regions covering 17,531 bp in citrus chloroplast genomes were obtained from yuzu. A phylogenetic tree based on these sequences showed that yuzu was most closely related to Ichang papeda (C. cavaleriei), suggesting that Ichang papeda might be a seed parent of yuzu. To identify paternal species, yuzu homologs of 103 single-copy genes found among citrus genomes were identified from a yuzu transcriptome that was de novo assembled using RNA-seq reads. Eighty homologous genes were identified from the yuzu transcriptome. A phylogenetic tree based on nucleotide sequence variations in 80 single-copy genes of yuzu and other Citrus species showed that yuzu was most closely related to mandarin. To assess hybrid origins of 80 single-copy genes, single nucleotide polymorphisms (SNPs) among yuzu, Ichang papeda, mandarin, citron, and pummelo were analyzed, and yuzu SNP genotypes were identified by visual investigation of alignments of RNA-seq reads. Forty-three out of 80 genes were assumed to originate from hybrids between Ichang papeda and mandarin. Taken together, results of this study indicate that Ichang papeda and mandarin might be the parental species of yuzu.

Variety improvement program of citrus in Indonesia has still been prioritized, therefore, characterization and identification of varieties within and/or among citrus species are absolutely required in order to obtain desired varieties based on market demand needs. The aim of this research was to determine morphological characteristics, flowering periods, and the genetic relationship of four citrus species. This study was carried out at Indonesia Citrus and Subtropical Fruit Research Institute (ICISFRI). A total of 12 varieties derived from Citrus reticulata Blanco, Citrus sinensis L. Osbeck, Citrus aurantifolia (Christm.) Swingle), and Citrus lemon (L.) Burm. F was used for morphological description. The genetic relationship was evaluated by morphological and molecular analyses using Inter-simple Sequence Repeat (ISSR). The result showed that variations of morphological characters were identified either within or among four citrus species. Citrus reticulata Blanco had the highest physiochemical contents. In terms of flowering periods, varieties that belong to Citrus reticulata Blanco, and Ortaji (Citrus sinensis L. Osbeck) required 9 to 11 days for fully blooming after flower bud; whereas Montaji (Citrus limon (L.) Burm. F) and Nimas (Citrus aurantifolia (Christm.) Swingle) needed 16 days. In both morphological and molecular analyses, 12 varieties were classified into two main clusters, however, some differences were found between the two dendrograms. The genetic relationship of four citrus species based on similarity coefficient ranged from 1 to 25 (morphological analyses) and 0.62 to 0.90 (ISSR marker), respectively. The highest genetic relationship derived from both analyses was performed by Krisma versus Monita, and Krisma versus Orlinda Kuning, respectively. Morphological analyses are still needed to complement molecular analyses in citrus classification in order to produce desired new citrus varieties in order to create sustained citrus agribusiness in Indonesia.
