The Seed Repair Response during Germination: Disclosing Correlations between DNA Repair, Antioxidant Response, and Chromatin Remodeling in Medicago truncatula
This work provides novel insights into the effects caused by the histone deacetylase inhibitor trichostatin A (TSA) during Medicago truncatula seed germination, with emphasis on the seed repair response. Seeds treated with H2O and TSA (10 and 20 μM) were collected during imbibition (8 h) and at the radicle protrusion phase. Biometric data showed delayed germination and impaired seedling growth ...
متن کاملSeed Hydropriming and Smoke Water Significantly Improve Low-Temperature Germination of Lupinus angustifolius L.
Seed imbibition under cold temperature is dangerous when dry seeds have relatively low water content. The aim of this study was to investigate germination of 20 lines/cultivars of narrow-leaf lupine at 7 °C (cold) and 13 °C (control) under the influence of smoke water and following seed hydropriming for 3 h at 20 °C. The efficacy of individual treatments was examined with regard to seed protect...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
A Sleep Like Death: Identification of Genes Related to Seed Longevity in Medicago truncatula and Arabidopsis.
Atmaturation, seeds generally becomedormant and desiccation tolerant; after dormancy breaks, the seeds remain quiescent for an indefinite period and will germinate only when providedwith adequatemoisture. Some seeds remain in this quiescent state for thousands of years, only to germinate under the right conditions, while other seeds fail to germinate after extendedstorage.Howdosomeseedssurvive ...
متن کاملModified expression of cysteine protease affects seed germination, vegetative growth and nodule development in transgenic lines of Medicago truncatula
Transgenic lines of Medicago truncatula (R108-1) were constructed to analyse Cyp15a (cysteine protease) gene functioning and localisation. The promoter region of PsCyp15a was fused to the coding sequence of uidA. GUS-analysis of transgenic plants containing this construct revealed strong expression from the Cyp15 promoter in cotyledonary leaves, senescent leaves, and root nodules. A seven-fold ...
