A R2r3 Myb Transcription Factor From Ash Positively Regulates Salt Response In Tobacco, Tian Li, Jingkuan Sun, Yuping Bi Jan 2017

A R2r3 Myb Transcription Factor From Ash Positively Regulates Salt Response In Tobacco, Tian Li, Jingkuan Sun, Yuping Bi

Turkish Journal of Biology

The roles of MYB transcription factors are diverse and important in regulating environmental stress in plants. In this study, the R2R3 MYB gene FvMYB2 (GenBank Accession No. KY767843) and its promoter region were cloned from ash (Fraxinus velutina Torr.). Phylogenetic analysis revealed that FvMYB2 was clustered with VvMYB60 from Vitis vinifera. PlantCARE software analysis showed that its promoter contained different cis elements involved in diverse abiotic stresses. The expression patterns of FvMYB2 were investigated under different abiotic stress conditions. FvMYB2 subcellular localization was mainly localized in the nucleus. Overexpression of FvMYB2 in tobacco showed enhanced salt resistance and upregulation of …


Inoculation With Bacillus Licheniformis Mh48 To Improve Camellia Japonicaseedling Development In Coastal Lands, Hyun-Gyu Park, Min-Hae Jeong, Young-Sang Ahn Jan 2017

Inoculation With Bacillus Licheniformis Mh48 To Improve Camellia Japonicaseedling Development In Coastal Lands, Hyun-Gyu Park, Min-Hae Jeong, Young-Sang Ahn

Turkish Journal of Agriculture and Forestry

This study aimed to determine the promotion of the growth and nutrient uptake of Camellia japonica seedlings in coastal lands by bacterial inoculation. Soil salinity reduces plant growth and development in coastal areas due to the osmotic stress that perturbs nutrient uptake. The soil electrical conductivity at the sites of this study ranged from 1.02 to 1.89 dS m-1. Application of chemical fertilizer resulted in the limited uptake of nutrients in seedlings under saline conditions as well as a low nutrient content in the soil caused by leaching, with no significant influence on the growth of the seedlings. However, Bacillus …


Characterization Of The Beta1 Gene, Which Might Play A Role In Beta Vulgaris Subsp. Maritima Salt Tolerance, Özge Uysal, Çi̇ğdem Çakiroğlu, Ahmet Koç, Hüseyi̇n Çağlar Karakaya Jan 2017

Characterization Of The Beta1 Gene, Which Might Play A Role In Beta Vulgaris Subsp. Maritima Salt Tolerance, Özge Uysal, Çi̇ğdem Çakiroğlu, Ahmet Koç, Hüseyi̇n Çağlar Karakaya

Turkish Journal of Botany

Salinity stress has a negative impact on plant growth, which affects homeostasis and productivity. The uptake of nonessential salt ions changes the osmotic balance of the cell and causes dehydration. Higher plants develop salt tolerance mechanisms to avoid dehydration. Sea beet (Beta vulgaris subsp. maritima) is a halophytic ancestor of cultivated sugar beet that displays salt stress tolerance. In this study, we screened a B. vulgaris subsp. maritima cDNA library in Saccharomyces cerevisiae strain Ab11c (ena1Δ, nha1/4Δ, nhx1Δ), which is deficient in sodium transport, to find sodium-detoxifying genes. We identified a cDNA construct, named BETA1, providing salt tolerance to yeast …


Response Of Five Triticale Genotypes To Salt Stress In In Vitro Culture, İsmai̇l Bezi̇rğanoğlu Jan 2017

Response Of Five Triticale Genotypes To Salt Stress In In Vitro Culture, İsmai̇l Bezi̇rğanoğlu

Turkish Journal of Agriculture and Forestry

Salinity is one of the important abiotic stresses that restrict plant development. Triticale is a highly adaptable crop, known for its high-quality grain, yield potential, and resistance to disease. Responses of five cultivated genotypes (Ümran Hanım, Mikham 2002, Melez 2001, Tatlıcak, and Alper Bey) of triticale to salt stress were tested in callus and embryogenic callus formation in this study. Cotyledon explants were selected as explants for callus induction and embryogenic callus formation. The five tested triticale genotypes varied in their callus growth and embryogenic callus formation. Ümran Hanım, Tatlıcak, and Alper Bey were observed for better callus induction; similarly, …


Comparison Of Two Halophyte Species (Salsola Soda And Portulaca Oleracea)For Salt Removal Potential Under Different Soil Salinity Conditions, Sema Karakaş, Mehmet Ali̇ Çullu, Murat Di̇ki̇li̇taş Jan 2017

Comparison Of Two Halophyte Species (Salsola Soda And Portulaca Oleracea)For Salt Removal Potential Under Different Soil Salinity Conditions, Sema Karakaş, Mehmet Ali̇ Çullu, Murat Di̇ki̇li̇taş

Turkish Journal of Agriculture and Forestry

Salt-induced land degradation has gradually increased in several major irrigation schemes within arid and semiarid regions. To maximize crop productivity under saline conditions, either salt tolerance crops should be cultivated or areas should be desalinated. One of the most promising and cost-effective ways to maximize crop productivity is to use salt tolerant plants to remove salt from the soil. For this study, four levels of saline soils were cultivated with the halophyte species Salsola soda L. and Portulaca oleracea L. in pots. The soils had the following salinity levels: 1) nonsaline soil (NSS, 0.9 dS m-1), 2) slightly saline soil …
