The nature and kinetics of reactions in dry seeds determines how long the survive. We used gas chromatography to assay volatile organic compounds (VOCs) emitted from three unrelated species as a means non-invasively probe chemical changes during very dry, humid storage (seeds were dried 5.5, 33, 75% relative humidity at room temperature). VOCs stored conditions reflected fermentation-type reactions, with methanol ethanol being predominant Lactuca sativa Carum carvi, acetaldehyde acetone...
Abstract Maximising seed longevity is crucial for genetic resource preservation and of orthodox seeds determined by environmental conditions (water content temperature). The effect water (down to 0.01 g·H 2 O·g −1 ) on viability was studied at different temperatures a 5‐year storage period in taxonomically related species. Seeds seven B rassicaceae species ( rassica repanda , E ruca vesicaria M alcolmia littorea oricandia arvensis R orippa nasturtium‐aquaticum S inapis alba isymbrium...
The duration that seeds stay vigorous during storage is difficult to predict but critical seed industry and conservation communities. Production of volatile compounds from lettuce was investigated as a non-invasive early detection method ageing rates. Over 30 were detected at 35 degrees C water contents ranging 0.03 0.09 g H(2)O g(-1) dw. Both qualitative quantitative differences in composition noted function content, these apparent before signs deterioration visible. Seeds stored high...
Abstract Seed longevity is a complex process of key ecological and agronomic importance. DNA damage significant factor affecting seed ageing. Likewise, epigenetic changes can control gene expression and, therefore, response to The aim the present work was investigate effect ageing on nucleic acid stability identify reliable molecular markers that might help monitor within plant genetic resources during conservation. profiles, evaluated by RAPD (random amplified polymorphic DNA), methylation...
The micronutrient Zinc (Zn) is essential for the proper growth and development of crops. oxide nanoparticles (NPs) fine particles are presented as an emerging alternative to more traditional fertilizers. In this study, possible toxic effect four laboratory-synthesized ZnO NPs with different characteristics on tomato seed germination vigor parameters was examined in comparison bulk ZnO. Different metal precursors were used chemical synthesis particles: Zn(NO3)2 ZnSO4, named NIT-. SUL-.,...
Thermal fingerprints for seeds of 20 crop wild relatives Brassicaceae stored 8 to 44 years at the Plant Germplasm Bank-Universidad Politécnica de Madrid and Royal Botanic Gardens, Kew's Millennium Seed Bank-were generated using differential scanning calorimetry (DSC) analyzed in relation storage stability. Relatively poor storing oily -20 °C tended have lipids with crystallization melting transitions spread over a wide temperature range (c. 40 °C) that spanned temperature, plus end around 15...
Seed ageing is a complex process and can be described as the loss of viability or quality with time. It important to elucidate whether genetic epigenetic stability altered in stored seeds seedlings produced from them. Non-stored rye at different stages were compared, well obtained Seeds 35 °C 15% water content, under vacuum air atmosphere. DNA was isolated three deterioration curve: P75 (13 days), P20 (29 P0 (36 days). Genetic assessed by RAPD technique, changes MSAP markers. While showed...

Abstract The broad aim of this work was to study intraspecific variation seed germination in Phillyrea angustifolia L. (Oleaceae), a species with hard (water-permeable) endocarp. Germination seeds from six different wild populations correlated traits related either morphology or environmental parameters. naked (seeds without endocarp) at the optimum conditions similar among and individuals, but great differences could be detected regarding endocarp both inter- intra-populational levels....
Many Fabaceae species have a hard and impermeable seed coat that requires scarification for germination.The variability within batch between batches of the same can be very high, resulting in inefficient dormancy breaking.The main objectives this study were to investigate hardseededness among four populations legume Medicago polymorpha, Trifolium glomeratum T. subterraneum, evaluate effect best treatments on mechanical properties coat.These small seeds hinder procedures.Different treatments,...

In this study, we evaluated scores obtained by students written exam results satisfaction survey. assessment showed that attained improved marks after being taught...
Osteoporosis is an aging-related disease and a worldwide health issue. Current therapeutics have failed to reduce the prevalence of osteoporosis in human population, thus discovery compounds with bone anabolic properties that could be basis next generation drugs priority.

Summary Seed dormancy governs germination timing, with both evolutionary and applied consequences. Despite extensive studies on the hormonal genetic control of these processes, molecular mechanisms directly linking remain poorly understood. By screening a collection lines overexpressing Arabidopsis transcription factors, we identified ERF50 as key gene to germination. To study its regulation, measured seed‐related physiological parameters in loss‐of‐function mutants carried out...
