The Investigation Of Group 1 Late Embryogenesis Abundant Protein 6 And Its Role In Arabidopsis Thaliana Desiccation Tolerance, Joann Eise Thomson
Masters Theses
Like most seeds, Arabidopsis thaliana seed development is divided into three major phases: morphogenesis, storage deposition, and maturation drying. During maturation drying the seed becomes desiccation tolerant (DT) at some point and the seed rapidly loses water until its moisture level is approximately 10% on a fresh weight basis. The ability of the seeds to withstand this extreme water loss is hypothesized to be due, in part, to the accumulation of late embryogenesis abundant (LEA) proteins. In A. thaliana, there are 51 LEA proteins which are divided into seven groups based on amino acid sequence similarities. Group 1 LEA …
The Effect Of Drying On Desiccation Tolerance And Late Embryogenesis Abundant Protein Gene Expression In Immature Seeds Of Phalaenopsis Amabilis, Huijing Zhu
Masters Theses
Orchidaceae as the most diverse family of flowering plants are endangered due to losing habitats or destruction of their unique symbiotic living style. Long-term seed storage banks can be a solution for threatened plant species but the stored seeds must tolerate extreme drying and cold. This ability is acquired during the last stage (maturation drying) of seed development and is correlated with a decline in water content and expression of the Late Embryogenesis Abundant (LEA) protein genes. Our goal is to investigate if premature orchid seeds can be artificially induced to become desiccation tolerant and the potential role of LEA …
