Characterization And Tissue-Specific As Well As Heat-Stress Expression Analysis Of Cbl-Interacting Protein Kinase Genes In Dimocarpus Longan Lour, Wei Zheng, Xueming Dong, Xuefei Yu, Qiuying Zhang

Turkish Journal of Botany

The CBL-interacting protein kinase (CIPK) gene family plays important roles in plant growth, development, and responses to abiotic stresses. To date, the CIPKs have been extensively identified and characterized in various plants. However, there have been few studies on CIPKs in Dimocarpus longan Lour (D. longan). In this study we identified eight putative CIPKs in D. longan (DlCIPKs) according to RNA-seq data. The physicochemical properties, subcellular localization, conserved motifs, phylogenetic relationships, glycosylation and phosphorylation sites, and gene ontology annotation were analyzed using bioinformatics tools. The tissue-specific and heat-stress-responsive expressions were systematically investigated as well. Ten motifs widely maintained by DlCIPKs …

Determination Of Optimum Harvest Date For Winter Malting Quality Barley In Northwest Arkansas, Paul Wolf, David Moon, Richard Esten Mason Jan 2019

Determination Of Optimum Harvest Date For Winter Malting Quality Barley In Northwest Arkansas, Paul Wolf, David Moon, Richard Esten Mason

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Due to the strict quality requirements, only 10% of worldwide barley is used for malting, though malting quality barley comes with a price increase of up to 50% or greater. With the craft brewery industry growing in Northwest Arkansas there is a growing demand for locally sourced malt quality barley. However, data are lacking regarding production practices for barley in Arkansas. The optimal harvest date for malting quality barley is at physiological maturity. This is because many of the malting traits (such as germination energy) decline as harvest is delayed, which make it difficult to meet the criteria for malting …

Moderate Level Of Toxic Boron Causes Differential Regulation Of Micrornas Related To Jasmonate And Ethylene Metabolisms In Arabidopsis Thaliana, Doğa Seli̇n Kayihan, Ceyhun Kayihan, Yelda Özden Çi̇ftçi̇

Turkish Journal of Botany

Earlier our colleagues detected that the genes related to jasmonate (JA), ethylene, and cell wall modification were significantly regulated under boron (B) toxicity in wheat. Determination of regulation mechanisms of these novel genes under B toxicity is very important in Arabidopsis thaliana as a model plant. As key regulators, the microRNAs (miRNAs) regulate gene expression at the posttranscriptional level and respond to numerous abiotic stresses in plants. In this study, expression levels of miRNAs such as miR159, miR172, miR319, and miR394 targeting JA and ethylene-related transcription factors and also miR397 targeting laccase were determined in Arabidopsis thaliana under toxic B …


Effects Of Salicylic Acid And Heat Acclimation On Thermotolerance And Withanolide Accumulation Under High Temperature Stress In The Cape Gooseberry (Physalisperuviana L.), Günce Şahi̇n Jan 2019

Effects Of Salicylic Acid And Heat Acclimation On Thermotolerance And Withanolide Accumulation Under High Temperature Stress In The Cape Gooseberry (Physalisperuviana L.), Günce Şahi̇n

Turkish Journal of Botany

The adverse effects of high temperature stress can be alleviated by thermotolerance induced by exogenous application of plant growth regulators or by gradual application of temperature stress. Physalis peruviana L., commonly known as the Cape gooseberry, is a source of a variety of phytocompounds such as withanolides (withanone, withaferin A, and withanolide A). These withanolides are potentially high-value drug candidates because of their various pharmacological properties. The production of withanolides via traditional agriculture is commercially inadequate. In the present study, elicitation strategies were employed to improve the crop's thermotolerance and accumulation of withanolides. For these purposes, the effects of heat …
