“…Salicornia bigelovii, known as dwarf glasswort, is a succulent halophytic (salt tolerant) plant proves to be a potential candidate to grow in salt marshes and intertidal areas on coasts of many countries (Loconsole et al, 2019) and can be irrigated with seawater (Glenn et al, 1998;Ventura and Sagi, 2013). There is an increasing concern about the use of S. bigelovii in human and animal diet as well as in biofuel production worldwide (Bañuelos et al, 2018;Doncato and Costa, 2018). In the UAE, the cultivation of S. bigelovii has become profitable.…”

Salicornia bigelovii is a promising halophytic cash crop that grows in seawater of the intertidal zone of the west-north coast of the UAE. This study assess plant growth promoting (PGP) capabilities of halotolerant actinobacteria isolated from rhizosphere of S. bigelovii to be used as biological inoculants on seawater-irrigated S. bigelovii plants. Under laboratory conditions, a total of 39 actinobacterial strains were isolated, of which 22 were tolerant to high salinity (up to 8% w/v NaCl). These strains were further screened for their abilities to colonize S. bigelovii roots in vitro; the most promising ones that produced indole-3-acetic acid, polyamines (PA) or 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase (ACCD) were selected for rhizosphere-competency under naturally competitive environment. Three outstanding rhizosphere-competent isolates, Streptomyces chartreusis (Sc), S. tritolerans (St), and S. rochei (Sr) producing auxins, PA and ACCD, respectively, were investigated individually and as consortium (Sc/St/Sr) to determine their effects on the performance of S. bigelovii in the greenhouse. Individual applications of strains on seawater-irrigated plants significantly enhanced shoot and root dry biomass by 32.3-56.5% and 42.3-71.9%, respectively, in comparison to noninoculated plants (control). In addition, plants individually treated with Sc, St and Sr resulted in 46.1, 60.0, and 69.1% increase in seed yield, respectively, when compared to control plants. Thus, the synergetic combination of strains had greater effects on S. bigelovii biomass (62.2 and 77.9% increase in shoot and root dry biomass, respectively) and seed yield (79.7% increase), compared to the control treatment. Our results also showed significant (P < 0.05) increases in the levels of photosynthetic pigments, endogenous auxins and PA, but a reduction in the levels of ACC in tissues of plants inoculated with Sc/St/Sr. We conclude that the consortium of isolates was the most effective treatment on S. bigelovii growth; thus confirmed by principal component and correlation analyses. To this best of our knowledge, this is the first report about

This succulent plant is used for human consumption and animal feed (Belal and Al-Dosari, 1999; Doncato and Costa, 2018); and its oilseeds are potential source for biofuel and biodiesel production (Bailis and Yu, 2012; Abideen et al, 2015). Thus, Salicornia spp.…”

Growth Promotion of Salicornia bigelovii by Micromonospora chalcea UAE1, an Endophytic 1-Aminocyclopropane-1-Carboxylic Acid Deaminase-Producing Actinobacterial Isolate

et al. 2019

View full text Add to dashboard Cite

Salicornia bigelovii is a promising halophytic crop for saline soils in semi-arid regions. This study was designed to characterize isolates of endophytic actinobacteria from S. bigelovii roots and evaluate the effects associated with plant growth promotion. Twenty-eight endophytic isolates obtained from surface-sterilized roots of S. bigelovii were initially selected based on their production of 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase in vitro in a chemically defined medium. Application of Micromonospora chalcea UAE1, possessing the highest ACC deaminase activity, to S. bigelovii seedlings significantly enhanced the plant growth under gnotobiotic and greenhouse conditions. This was clear from the increases in the dry weight and length of both shoot and root, and seed yield compared to the non-ACC deaminase-producing isolate Streptomyces violaceorectus , or control treatment. The growth promotion was also supported by significant increases in the content of photosynthetic pigments and the levels of auxins, but significant decreases in the levels of ACC in planta . Under greenhouse conditions, M. chalcea recovered from inside the inoculated roots in all samplings (up to 12 weeks post inoculation), suggesting that the roots of healthy S. bigelovii are a suitable habitat for the endophytic actinobacterial isolates. Pure cultures of M. chalcea were not capable of producing auxins, gibberellic acid, cytokinins or polyamines in vitro . This indicates that the growth promotion is most likely to be due to the reduction of the endogenous levels of the stress hormone ethylene. Our findings suggest that growth and yields of S. bigelovii can be enhanced by the field application of the endophyte M. chalcea UAE1. This study is the first to report potential endophytic non-streptomycete actinobacteria to promote the growth of halophytic plants in semi-arid zones under greenhouse conditions.

“…Moreover, it contains a considerable amount of dietary fiber (30.27% neutral detergent fibers and 13.16% acid detergent fibers on dry weight basis), which is known to be important for bowel health (Durant et al., 2006). With the values obtained from the proximate analysis, calculated daily consumption of 20 g of Salicornia dry shoots would partially supply the recommended daily intake of several mineral elements including Fe (48%), Mg (33%), Ca (14%), P (9%), and K (8%) and 100% supply of required daily Mn amount for an adult (Doncato & Costa, 2018).…”

Domestication of novel crops from the wild is a key process that ensures food security by addressing adaptability to changing environments. These wild plants offer broader and unique health benefits beyond basic nutrition. Salinization resulted in a drastic reduction of arable land and freshwater intended for cultivation. Thus, the global food production is currently under a risk of meeting the demands. Salt‐tolerant plants (i.e., halophytes) are potential food candidates that can be used to increase the productivity of salinized land and also to enhance the diversification of food production. Salicornia can survive under hypersaline and extreme climatic conditions and deliver tender shoots and dried seeds that can be used as a food with a unique taste, texture, and therapeutic benefits. Although Salicornia is not equally popular among all the food cultures globally, it has been consumed over centuries, and it is now making its way to the shelves of supermarkets in some countries such as the United States, UAE, South Korea, and Mexico. Despite being an underutilized crop, Salicornia possesses an array of chemical compounds or basic derivatives that can enhance antioxidant, anti‐obesity, antidiabetes, anti‐inflammatory, cardioprotective, and neuroprotective properties of human nutrition. The presence of considerable amounts of nutritional elements and various functional bioactive phytochemicals have opened up avenues of using Salicornia as a functional food. The present paper reviews the recognition of Salicornia as a functional food and a potential cash crop in saline agriculture to enhance agricultural productivity and also to diversify the current food supply chain.
