“…Features found in this study is initial report anatomical structure of Suaeda maritima in Thailand showed that the species is austrobassioid (C3) types of leaf anatomy which the leaf is distinctly succulent, flattened to more or less semiterete, on adaxial side usually concave, at base somewhat attenuated; vascular system in a curved more or less central horizontal with the 3-4 mesophyll layers on each side strongly increasing in size towards the center and with decreasing numbers of chloroplasts, the innermost 1or 2 layers as aqueous tissue, usually lacking of chloroplasts, without air spaces (Schütze et al 2003). A similar statement was drawn for populations of many regions such as North American, European and Asian coastal areas in which a considerable proportion of the variation observed in fieldcollected material was attributed to phenotypic plasticity (Yeo and Flowers 1980;Fisher et al 1997;Lomonosova et al 2008;Wetson et al 2012;Prinz et al 2013;Raju and Kumar 2016;Kim and Chung 2018;Voronin et al 2019).…”

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.

“…mongolica, seek to explain the importance of "dormancy" and "seed bank" for the maintenance and regeneration of populations. This plant, an annual herb with succulent leaves, grows in the cold desert of Inner Mongolia and other parts northern China [38,39]. Seed-bank dynamics, including dormancy cycling of dimorphic seeds, has been studied in detail.…”

Seed Dormancy and Germination

In recent years, global climate change has been altering environmental (severe drought, soil salinization, irregular precipitation, etc.), around world, decreasing crop yield and upsetting the balance of ecosystems. Nonetheless, a group of plants known as halophytes have the ability to survive and develop in saline soils (wetlands, deserts or temperate zones), may be used in agriculture as a possible alternative to crops (salt-sensitive), as well as for fodder, energy production, medicinal purposes, and desalination of salt-affected areas (phytoremediation). This chapter provides a comprehensive summary of the adaptive strategies used by the annual and perennial halophytes on ecophysiological perspectives, to survive in diverse habitats. The results show a great diverse strategies, such as heteromorphism, seed banks, dormancy, rapid germination, and recovery capacity, from saline shock, favoring the chances of seed survival, although these mechanisms depend on light, moisture, temperature, and the type of salt, in which seeds germinate. In addition, it has been included some molecular, and biochemical aspects, discovered in last years, that might improve our understanding of physiology of these plants. It can conclude that halophytes may be as a possible alternative to ease pressure on cropping systems, restored lands degraded, or confer stress tolerance trough gene transfer.

“…Mey . (Lomonosova et al, 2008 ;Marhold, 2009), generally the basic chromosome number (X) of Chenopodiceae was (9) (Balaei et al, 2004;Gomurgen andAltinozlu, 2005 andOuarda et al, 2006). Goldblatt (1981) and Goldblatt and Johnson (1991) adduced the diploid chromosome numbers 18in some Arthrocnemum species such as A. glaucum, also this number recorded by Ghaffari et al (2006) in the somatic cell (2n) in A .macrostachyum.…”

The pollen morphology characters and chromosome number of Arthrocnemum glaucum Del., Halocnemum strobiloceum (Pall.) M. Bieb. and Salicornia europaea L. (Salicornieae: Chenopodiaceae) plants were studied. The pollen grains were characterized by isopolate, spheroidal, polyporate, circular pore and verrucate ornamentation, while the pollen diameter, pore number and C/D ratio have been shown to give a good taxonomic value, the results illustrated divided the species in tow groups. The first group includes A. glaucum and S. europaea with small size of pollen grains, while isolated H. strobiloceum in other group.The chromosomal numbers were count in all species, which divided into two groups, the first was includes the H. strobiloceum and S. europaea species with (n= 18) chromosome, while A. glaucum was posited on the other group with (n= 9) chromosome.
