“…Remarkably, leaves from S. maritima species contain small amounts of spongy parenchyma, which primarily consists of elongate cells that resemble palisade cells. This anatomy, termed austrobassioid (Carolin et al 1975;Fisher et al 1997;Schütze et al 2003), is typical for most C3 plants of the genus Suaeda (Figure 3G-3I). Furthermore, sections of stems from all coloration morphs of S. maritima reveal round epidermal cells.…”

“…It comprises typically of halophytic leaf-succulents that grow in salty and basic wetlands and deserts. Based on recent morphomolecular evidence, Suaeda is presently recognized in subfamily Suaedoideae of Chenopodiaceae (Fisher et al 1997;Schütze et al 2003;Brandt et al 2015; Kim and Chung 2018;www.theplantlist.org). The subfamily is categorized by fleshy leaves, the occurrence of bracteoles, membranaceous.…”

Abstract. Rittirongsakul K, Srinual A, Vanijajiva O. 2020. Anatomical features and SCoT profiles provide new insight into phenotypic plasticity in the halophyte Suaeda maritima in Thailand. Biodiversitas 21: 1082-1090. Phenotypic plasticity is the variation in phenotypic traits of organisms to survive with fluctuating environments. Halophytes are plants that can naturally tolerate high concentrations of salt in the soil, and their tolerance to salt stress, which reflects the ability of the plants to produce different phenotypic traits in response to changing environmental conditions. Suaeda maritima (L.) Dumort is a polymorphic halophyte and prominent species complex from tropical to temperate regions due to diverse stressful saline habitats. Consequently, the identification of S. maritima based on morphological data is challenging due to high phenotypic plasticity. In Thailand, S. maritima, known as Seablite or Cha Khram, has only been reported for the genus Suaeda which frequently found in coastal salt marshes. The peculiarities of the prevalence of three distinctive color traits, green, green-reddish and reddish, were commonly observed in Thailand. This preliminary study aims to examine the morpho-anatomical characters and molecular analysis of S. maritima and to determine how their morphological and genetic characterizations are related to phenotypic traits, particularly in color variation within the population at Bang Khun Tien shoreline in Bangkok, Thailand. This combined investigation of anatomical characters and start codon targeted (SCoT) fingerprinting profiles provide first evidence of phenotypic variations and genetic characterizations of halophytic S. maritima in Thailand. Anatomical characters of leaf structures confirmed that the species is austrobassioid (C3) types. Meanwhile, molecular investigation of thirty SCoT primers found that only two SCoT primers (SCoT10 and SCoT27) failed to amplify the S. maritima genomic DNA. Thoroughly, twenty-eight SCoT primers produced 162 unambiguous and reproducible banding profiles with 140-1200 bp product size. Despite, there was no genetic variation detectable within the population, SCoT technique was considered a suitable tool to produces adequate characterization for DNA fingerprinting of halophyte S. maritima. However, further studies involving additional samples of S. maritima are needed to obtain a more general view of the conspicuous variation and colonization history in Thailand.

“…In addition to the ploidy level, S. arctica clearly differs from S. corniculata by the pinkish color, compact inflorescences, smaller fruits, shape of perianth segments and the short adpressed leaves. That these taxa are also separate genetically was established on the basis of molecular-phylogenetic analysis (Brandt et al, 2015) and ISSR fingerprinting (Lomonosova et al, 2017). In these papers, plants collected in Yakutia were discussed under the preliminary name S. 'jacutica'.…”

“…Many species of this family live in inland saline and coastal salt marsh area [ 38 ]. While there are many studies on the phylogeny of Chenopodiaceae [ 39 ; 40 ; 41 ; 42 ; 43 ; 44 ], there are only 12 samples of 12 species of Chenopodiaceae reported by Bafeel for DNA barcode research [ 45 ]. The two families have a large number of widely distributed species that can grow coastally and inland, which provides an excellent model for a coastal/inland halo-tolerant plant DNA barcode comparative study.…”

Evaluating sampling strategy for DNA barcoding study of coastal and inland halo-tolerant Poaceae and Chenopodiaceae: A case study for increased sample size

et al. 2017

Environmental conditions in coastal salt marsh habitats have led to the development of specialist genetic adaptations. We evaluated six DNA barcode loci of the 53 species of Poaceae and 15 species of Chenopodiaceae from China's coastal salt marsh area and inland area. Our results indicate that the optimum DNA barcode was ITS for coastal salt-tolerant Poaceae and matK for the Chenopodiaceae. Sampling strategies for ten common species of Poaceae and Chenopodiaceae were analyzed according to optimum barcode. We found that by increasing the number of samples collected from the coastal salt marsh area on the basis of inland samples, the number of haplotypes of Arundinella hirta, Digitaria ciliaris, Eleusine indica, Imperata cylindrica, Setaria viridis, and Chenopodium glaucum increased, with a principal coordinate plot clearly showing increased distribution points. The results of a Mann-Whitney test showed that for Digitaria ciliaris, Eleusine indica, Imperata cylindrica, and Setaria viridis, the distribution of intraspecific genetic distances was significantly different when samples from the coastal salt marsh area were included (P < 0.01). These results suggest that increasing the sample size in specialist habitats can improve measurements of intraspecific genetic diversity, and will have a positive effect on the application of the DNA barcodes in widely distributed species. The results of random sampling showed that when sample size reached 11 for Chloris virgata, Chenopodium glaucum, and Dysphania ambrosioides, 13 for Setaria viridis, and 15 for Eleusine indica, Imperata cylindrica and Chenopodium album, average intraspecific distance tended to reach stability. These results indicate that the sample size for DNA barcode of globally distributed species should be increased to 11–15.
