Generation Of Transgenic Tall Fescue Plants With Enhanced Abiotic Stress Tolerance, I. Alam, Y. G. Kim, K. H. Kim, N. Y. Ahn, B. H. Lee
IGC Proceedings (1997-2023)
Environmental stresses, such as drought, salinity and temperature extremes significantly decrease the yield of forage crops. Therefore, traits associated with abiotic stress-tolerance are of prime importance for their improvement. Biotechnological approaches have the potential to accelerate and complement conventional breeding by extending the range of gene sources for valuable traits, thus offering new opportunities for forage improvement. Transgenic technology appears as an efficient biotechnological tool of molecular breeding for improving forage quality and yield as well as tolerance to various environmental stresses. Occurrence of high level of reactive oxygen species (ROS) is a common phenomenon in abiotic stress-challenged plants. Plants …
Quantitative Proteome Analysis Of Alfalfa In Drought Stress Under The Influence Of Mir156, Alpa Puri
Quantitative Proteome Analysis Of Alfalfa In Drought Stress Under The Influence Of Mir156, Alpa Puri
Electronic Thesis and Dissertation Repository
Medicago sativa is one of the most produced perennial forage crops in Canada. Drought stress is a major form of abiotic stress affecting the productivity and annual yield of alfalfa. A small noncoding RNA, miR156 has a role in abiotic stress tolerance, while regulating downstream SPL genes. In this study, whole leaf proteome and amino acid concentrations of miR156OE (A8) genotype of alfalfa under drought stress were quantified. In results, 3,000 proteins groups were identified using MaxQuant when searched against Medicago truncatula protein sequence database. Gene ontology analysis showed enriched proteins were involved in biological and molecular processes such as …
Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Competitiveness Of Generalist Plant Populations At A Mine Site, Justin S.H. Wan, Fati̇h Fazlioğlu, Stephen P. Bonser
Turkish Journal of Botany
Plants inhabiting extremely stressful mine site environments tend to be specialized and localized, where they express lower performance than nonmine site plants from adjacent areas. However, such a cost may be concealed. In a previous study at a mine site, we found mine and adjacent nonmine plants of multiple species expressed similar performances in the absence of competition. However, a lower competitive ability may be a concealed driver. We aim to test whether costs under competition could explain specialization. In a glasshouse experiment, we measured the performance (i.e. vegetative and reproductive growth) of mine and nonmine potted plants under competition. …
Roles Of Plant Cbl?Cipk Systems In Abiotic Stress Responses, Shilian Huang, Shaofeng Jiang, Junsong Liang, Miao Chen
Roles Of Plant Cbl?Cipk Systems In Abiotic Stress Responses, Shilian Huang, Shaofeng Jiang, Junsong Liang, Miao Chen
Turkish Journal of Botany
Plants evolved from long-term adaptation to form regulatory mechanisms of perception, transduction, and response to stresses. The CBL?CIPK signaling system is a basic calcium sensor that plays an important role in sensing adverse environmental stimuli. CBLs can perceive and bind Ca2+ under adversity and then specifically interact with CIPKs. The activated CBL?CIPK complex phosphorylates downstream target proteins (such as ion channels and transporters), or regulates transcription factors and stress responsive genes. Important progress has been made in the study of CBL?CIPK signaling pathways in response to high salt, low N, low K, high Mg, and high pH. This review summarizes …
Interactive Effects Of Salinity And Inundation On Native Spartina Foliosa, Invasive S. Densiflora And Their Hybrid From San Francisco Estuary, California, Blanca Gallego-Trevar, Brenda J. Grewell, Caryn J. Futrell, Rebecca E. Drenovsky, Jesus M. Castillo

Sea level rise (SLR) associated with climate change is intensifying permanent submersion and salinity in salt marshes. In this scenario, hybridization between native and invasive species may result in hybrids having greater tolerance of abiotic stress factors than their parents. Thus, understanding the responses of native and invasive halophytes and their hybrids to interacting physiological stresses imposed by SLR is key to native species conservation. We analysed how salinity, inundation depth and their interaction impact the functional traits of native and invasive cordgrass species and their hybrid (genus Spartina; Poaceae).
