“…Results showed that C. hongheensis is close related to the Citrus species and the relationship between the chloroplast genome of C. hongheensis and C. maxima was the closest, which was consistent with the results reported by Wang and Jiang ( 2010 ) and Li et al. ( 2015 ) ( Figure 1 ). The C. hongheensis complete chloroplast genome reported in this study can provide basis for the future origin and evolution researches of Citrus species.…”

“…By using the complete chloroplast genomes of C. hongheensis, 20 plant species from Rutaceae family and Ailanthus altissima (as outgroup) (Xu et al 2019), a maximum-likelihood phylogenetic tree was constructed to reveal its phylogenetic relationship with Citrus species from the chloroplast genome level. Results showed that C. hongheensis is close related to the Citrus species and the relationship between the chloroplast genome of C. hongheensis and C. maxima was the closest, which was consistent with the results reported by Wang and Jiang (2010) and Li et al (2015) (Figure 1).

Citrus hongheensis is a key protected wild plant endemic to the Honghe river region in southeastern Yunnan, China. In the present study, its chloroplast genome was successfully assembled and annotated based on the Illumina Hiseq-2500 whole genome re-sequencing data. The chloroplast genome is 160,275 bp in size. Its large single copy region, small single copy region and inverted repeat region is 87,886 bp, 18,387 bp and 27,001 bp, respectively. Totally, 114 unique genes, including 80 protein-coding genes, 30 tRNAs and 4 rRNAs, were identified from the C. hongheensis chloroplast genome. According to the phylogenetic analysis result, the relationship between the chloroplast genome of C. hongheensis and C. maxima was found to be the closest.

“…Naringin and neohesperidin are rich in sour orange [37], and they are also the predominant flavanones in grapefruit. In the current study, local cultivar ZPG (C. reticulata), which might originate from interspecific hybridization between C. sinensis and C. reticulata [38], was characterized by neohesperidin and naringin. However, flavonoids are highly similar in the peels of JJSC (C. aurantium) and JPG (C. reticulata), which may correlate with high chemotype similarities between hybrids and their ascendants [39].…”

Flavonoid profile and antioxidant activity of citrus peels, pulps, and juices from 27 local citrus cultivars in China were investigated. Flavonoid composition and content were determined using UPLC-PDA. Total phenolic content (TPC) and total flavonoid content (TFC) were measured using a Folin–Ciocalteau reagent and Al(NO3)-NaNO2 complexometry, respectively. The antioxidant capacities of the extracts were evaluated by DPPH, ABTS and FRAP method, respectively. Citrus peel not only exhibited better antioxidant potential, but also presented more composition diversity and contained higher concentrations of flavonoids than pulp and juice. Different citrus species were characterized by their individual predominant flavonoids, contributing largely to the antioxidant activity, such as mandarin was characterized by hesperidin, nobiletin and tangeretin, while pummelo and papeda were characterized by naringin. The peel of Guihuadinanfeng (Citrus reticulata) had the highest TPC of 23.46 mg equivalent gallic acid/g DW (dry weight) and TFC of 21.37 mg equivalent rutin/g DW. Shiyueju (C. reticulata) peel showed the highest antioxidant capacity based on the antioxidant potency composite (APC) analysis. Overall, mandarin (C. reticulata) fruits peel contained more TPC and TFC, exhibiting higher antioxidant capacities than other species, and were good natural sources of flavonoids and antioxidants.

“…Citrus wilsonii is a citrus rootstock native to the Southern Qinling Mountains in China that has been cultivated for more than 500 years ( Li et al, 2018 ). The rootstock cultivar of C. wilsonii is also called “Zhique” in Chenggu county of Shaanxi province, China, where it has been cultivated as a traditional medicine in the Chinese Pharmacopoeia ( Cheng et al, 2017 ).…”

“…Zhique is a natural hybrid citrus variety with pummelo ( Citrus maxima ) as the female parent and trifoliate orange [ Poncirus trifoliata (L.) Raf.] as the male parent, based on nuclear and chloroplast simple sequence repeat (SSR) markers analysis ( Li et al, 2018 ). As a citrus rootstock, Zhique shows strong tolerance to iron deficiency in calcareous soil that is better than the most commonly used trifoliate orange rootstock ( Fu et al, 2016 ).…”

Polyploidy varieties have been reported to exhibit higher stress tolerance relative to their diploid relatives, however, the underlying molecular and physiological mechanisms remain poorly understood. In this study, a batch of autotetraploid Citrus wilsonii were identified from a natural seedling population, and these tetraploid seedlings exhibited greater tolerance to drought stress than their diploids siblings. A global transcriptome analysis revealed that a large number of genes involved in photosynthesis response were enriched in tetraploids under drought stress, which was consistent with the changes in photosynthetic indices including Pn, gs, Tr, Ci, and chlorophyll contents. Compared with diploids, phosphorylation was also modified in the tetraploids after drought stress, as detected through tandem mass tag (TMT)-labeled proteomics. Additionally, tetraploids prioritized the regulation of plant hormone signal transduction at the transcriptional level after drought stress, which was also demonstrated by increased levels of IAA, ABA, and SA and reduced levels of GA3 and JA. Collectively, our results confirmed that the synergistic regulation of photosynthesis response, phosphorylation modification and plant hormone signaling resulted in drought tolerance of autotetraploid C. wilsonii germplasm.
