Sixteen known compounds, including three lignan glycosides (1-3), seven phenolic glycosides (4-10), three glycosides (11-13), and three flavonoids (14-16), were isolated from the rhizomes of Actinidia kolomikta (Rupr. & Maxim.) Maxim., Actinidiaceae. Their structures were elucidated through extensive spectroscopic analyses and comparison with those reported in the literature. This study is the first confirmation of the presence of the twelve compounds (1-4, 6-13) isolated from the Actinidiaceae family. The isolated compounds were evaluated for their inhibitory effects on NO, TNF-α, and IL-6 production in LPS-induced RAW264.7 cells. Among them, salidroside (9), D-threo-guaiacylglycerol 7-O-β-D-glucopyranoside (10), and epi-afzelechin (15) exhibited the potent anti-inflammatory effect against NO, TNF-α, and IL-6. In addition, compound 10 showed significant inhibitory effects on COX-2 expression at 50 μM, and compound 15 showed significant inhibitory effects on iNOS expression at 50 μM. These results suggest that the anti-inflammatory activity of A. kolomikta might in part occur via the inhibition of the expression of the pro-inflammatory cytokines.

“…Chromosome counting is a direct method to establish the ploidy of a plant. This approach can be very laborious and unreliable in A. arguta because of small size and relatively high number of chromosomes (> 110) (Yan et al 1997;Huang 2016;Bogačiovienė et al 2019). On the other hand, FCM is a quick and reliable method of measuring nuclear DNA content in plants and DNA-ploidy can be calculated from the 2C value of a control plant with known ploidy (Bogačiovienė et al 2019).…”

Endosperm, an ephemeral and storage tissue, serves as a source of nutrition and protection during embryo development and germination. It can be used for the cultivation of polyploid plants in vitro. Here, results of plant regeneration and acclimatization from the endosperm-derived calli of four cultivars of Actinidia arguta has been presented. Seeds excised from fresh fruit and dry seeds stored for one year served as the sources of endosperm explants of selected tetraploid cultivars of A. arguta. Callus Induction Medium (CIM; containing 0.25, 0.5, or 1 mg/l of TDZ) and Actinidia Endosperm Medium (AEM; containing 2 mg/l of 2,4-D and 5 mg/l of kinetin) were used to study the organogenic responses of the calli. On AEM, the source of explant did not significantly affect the rate of callus induction for any of the tested cultivars; no organogenic events were observed. In contrast, on CIM both the source of explants and the cultivar origin caused significant differences in callus formation and subsequent organogenic events. Histological and ultrastructural analyses revealed the adventitious nature of shoot bud formation on these media. The most efficient elongation of shoot buds was achieved after transferring organogenic calli with adventitious shoot buds to a medium supplemented with zeatin or meta-topolin. Robust root induction with minimal basal callus formation occurred on the medium with indole-3-acetic acid. Flow cytometric analysis revealed that the nuclear DNA content in the leaves of some regenerants was approximately 50 % higher (4.5 pg/2C) than that in leaves from the tetraploid seedlings (3.1 pg/2C),which confirmed that those regenerants originated from the endosperm. The regeneration of such hexaploid plants was more efficient when endosperm from fresh seeds served as an explant; therefore, fresh rather than dry seeds are recommended for endosperm-derived plant production. The hexaploid plants of A. arguta can serve as an important source of breeding material.

“…In addition, higher genetic diversities have been detected in the taxa with higher ploidy levels in several plant groups (e.g. Mallet 2007 ; García‐Verdugo et al 2009 ; Bogačiovienė et al 2019 ; Zhang et al 2019 ). At the same time, earlier studies have observed plenty of natural hybrids among Isnardia taxa in the field and reported the high capability of interspecific hybridization among Isnardia taxa in breeding experiments at research greenhouses (Raven and Tai 1979 ; Peng 1988 , 1989 ; Peng et al 2005 ).…”

“…Second, we reevaluated the estimated ages of Isnardia TMRCA (Hung et al 2009 ). Third, we tested the proposition that, as with many other allopolyploid plant groups (Mallet 2007 ; García‐Verdugo et al 2009 ; Bogačiovienė et al 2019 ; Zhang et al 2019 ), genetic diversities of Isnardia taxa increase with their ploidy levels. Fourth, consistent with earlier field observations and breeding experiments (Raven and Tai 1979 ; Peng 1988 , 1989 ; Peng et al 2005 ), we investigated the interspecific gene flows among Isnardia taxa with different ploidy levels.…”

Background While polyploids are common in plants, the evolutionary history and natural dynamics of most polyploid groups are still unclear. Owing to plentiful earlier systematic studies, Ludwigia sect. Isnardia (comprising 22 wetland taxa) is an ideal allopolyploid complex to investigate polyploid evolution and natural dynamics within and among taxa. With a considerable sampling, we concentrated on revisiting earlier phylogenies of Isnardia, reevaluating the earlier estimated age of the most recent common ancestor (TMRCA), exploring the correlation between infraspecific genetic diversity and ploidy levels, and inspecting interspecific gene flows among taxa. Results Phylogenetic trees and network concurred with earlier phylogenies and hypothesized genomes by incorporating 192 atpB-rbcL and ITS sequences representing 91% of Isnardia taxa. Moreover, we detected three multi-origin taxa. Our findings on L. repens and L. sphaerocarpa were consistent with earlier studies; L. arcuata was reported as a multi-origin taxon here, and an additional evolutionary scenario of L. sphaerocarpa was uncovered, both for the first time. Furthermore, estimated Isnardia TMRCA ages based on our data (5.9 or 8.9 million years ago) are in accordance with earlier estimates, although younger than fossil dates (Middle Miocene). Surprisingly, infraspecific genetic variations of Isnardia taxa did not increase with ploidy levels as anticipated from many other polyploid groups. In addition, the exuberant, low, and asymmetrical gene flows among Isnardia taxa indicated that the reproductive barriers may be weakened owing to allopolyploidization, which has rarely been reported. Conclusions The present research gives new perceptions of the reticulate evolution and dynamic nature of Isnardia and points to gaps in current knowledge about allopolyploid evolution.
