“…Total cpDNA size of Sonchus sp has range 152.071 to 152.194 bp (Cho et al 2019) with 1428 bp of rbcL gene (Kim et al 2019) and 1530 bp of matK gene (Kim et al 2007). Refer to Kim et al (2007) and Mejías et al (2018) that Sonchus brachyurous and S. arvensis are closely related base on matK region and put them together into a single clade. This study presents a new phylogenetic analysis of S. arvensis using rbcL barcode since numerous deposited sequence in Genbank are unpublished.…”

“…Another barcode that employed for DNA barcoding Sonchus sp is ITS (Mejías et al 2018;(Kim et al 2007). The ITS spacer is a robust phylogenetic marker at the species level indicating high levels of interspecific separation (Alvarez and Wendel 2003).…”

“…So far, study about the molecular indicator of Sonchus sp has been widely conducted by using various marker such as ISSR (Psaroudaki et al 2015;Subositi and Mujahid 2019), RAPD (Elkamali et al 2010;Doğan et al 2018), multiple-locus barcode matK-ITS (Kim et al 2007;Mejías et al 2018) moreover complete plastid genome (Cho et al 2019;Kim et al 2019). However, still, limited data provide molecular marker, primarily for S. arvensis using rbcL and matK locus.…”

Abstract. Wahyuni DK, Rahayu S, Purnama PR, Saputro TB, Suharyanto, Wijayanti N, Purnobasuki H. 2019. Morpho-anatomical structure and DNA barcode of Sonchus arvensis L. Biodiversitas 20: 2417-2426. Tempuyung or show thistle (Sonchus arvensis L.) belongs to the Asteraceae. Morpho-anatomy and DNA (Deoxyribonucleic Acid) barcoding of the plant correlates with species identification and metabolite synthesis. This research aims to look at morpho-anatomical structures and analyze the DNA barcode of Sonchus arvensis L (tempuyung). Three samples used for morpho-anatomical analysis are leaves, stems, roots, fruit, and seeds. Anatomical samples are made using the embedding method. DNA barcode uses multiple locus from plastid genome: rbcL and matK. Morpho-anatomical structure of tempuyung showed a similar structure of Sonchus genus. The stem presents in the intercellular space, whereas the roots and leaves present in the vascular tissue and the seeds. Fruits present in each part of the body. Tissues that formed root are epidermis, cortex, endoderm, and stele. Tissues that formed stem are epidermis, cortex, and stele. Tissues that formed leaf are epidermis, cortex, phloem, and xylem. Tissues that formed the fruit and seed are paranormal and sclerenchyma tissues. Sonchus arvensis sequence for rbcL has a similar 100% maximum identity to rbcL gene of S. arvensis, Sonchus asper, and Sonchus oleraceus, whereas Sonchus arvensis matK sequence has a similar 99.31% maximum identity to other S. arvensis matK sequences in BLAST system. These findings provide morpho-anatomical features and DNA barcoding for identification of S. arvensis. from others species in the same genus. Thus also can be considered as pharmaceutical standard.

“…Stebbins et al (1953) hypothesized that S. oleraceus (2n = 32) has an amphidiploid origin, involving hybridization between S. asper (2n = 18) and S. tenerrimus L. (2n = 14). Although chromosome numbers, morphological characteristics, and phylogenetic analysis provide some evidence to support this hypothesis, no corroborating results or conclusive evidence have been generated yet (Mejías and Andrés, 2004;Mejías et al, 2018). Therefore, in order to infer its phylogenetic divergence and expansion history on a local and global scale, it is of great importance to determine the origin of amphidiploid S. oleraceus.Given their high level of polymorphism, co-dominant inheritance patterns, and wide genomic distribution, microsatellites have been proven to be useful in estimating genetic diversity and characterizing population genetic structure, as well as for hybrid identification (Chen et al, 2017;Li et al, 2019).…”

Premise The common sowthistle, Sonchus oleraceus (Asteraceae), is a globally invasive weedy species. In order to investigate its genetic diversity, population genetic structure, and evolutionary history, we developed and characterized nuclear simple sequence repeat markers (SSRs or microsatellites). Methods and Results Seventeen microsatellite primer pairs were developed based on the Illumina sequence data. Ten developed SSR loci were polymorphic in four populations sampled from broad geographical regions. The number of alleles per locus ranged from one to 11, and the levels of observed and expected heterozygosity ranged from 0.000 to 1.000 and from 0.000 to 0.801, respectively. Up to 82% of the newly developed primer pairs were successfully amplified in the congeneric taxa S. asper, S. asper subsp. glaucescens, S. canariensis, and S. palmensis. Conclusions The SSR markers developed in this study will be useful for future population genetic studies on S. oleraceus and other congeneric species.

PremiseIsland plants have long interested biologists because of their distinctive morphological features and their isolation on small land areas in vast oceans. Studies of insular endemics may include identifying their ancestors, tracing their dispersal to islands, and describing their evolution on islands, including characters adaptive to island life. Thamnoseris is a monospecific genus endemic to the Desventuradas Islands, Chile. Its origins and relationships are unresolved, given the challenges of getting to the islands and accessing plants there.MethodsSequences from ITS of nrDNA and the complete chloroplast genome were employed to resolve phylogenetic relationships of Thamnoseris.ResultsPhylogenetic analyses of nuclear and chloroplast sequences showed Thamnoseris nested within or sister to Dendroseris, the largest endemic genus in the Juan Fernández Islands.ConclusionsThamnoseris evolved from a common ancestor of all or most species of Dendroseris prior to the diversification of Dendroseris in the Juan Fernández archipelago. The ancestor of Thamnoseris dispersed to the Desventuradas archipelago, which consists of the islands San Ambrosio and San Félix, within the past 3 Ma (the age of San Ambrosio). This is the only known example of possible plant dispersa\l between the Juan Fernández and Desventuradas Islands. We also mention two less likely biogeographic scenarios for the origin of Thamnoseris, which has features not seen in Dendroseris: small capitula with yellow florets; style branches barely divergent; and basally swollen subtending involucral bracts, all features associated with selfing and reduced dispersal. Goats and rabbits (now removed) reduced T. lacerata, once very abundant on the Desventuradas Islands, to several plants, making it of extreme conservation concern and worthy of further study.
