Abstract:
... While cheating can cause the degradation or collapse of mutualisms, mutualisms may theoretically stabilize or strengthen if the cheating is mutual. Here, we present an asymmetric two‐player game model to explore the evolutionary dynamics of mutual cheating in a mutualistic interaction. We found that the interaction evolved toward mutual cheating if cheating can help both partners obtain higher ben ...

Abstract:
... This study firstly quantified the responses of seeds of Zostera marina to different planting times (22 September, 5 October, 23 October, 7 November and 20 November in 2015) through a field seed-planting experiment over a two year period. The suitable seed planting time required by the seeds of Z. marina was evaluated. The seedling establishment rate of Z. marina subjected to different planting tim ...

Abstract:
... Reduced and soil-protective tillage technologies may represent certain negatives for cultivated crops associated with the biomass of mulch from intermediate crops and post-harvest residues. Sown crops, as well as field weeds, are exposed to impaired soil conditions. Soil conditions were assessed using biological tests. Eight plant species were chosen for the tests. Germination of tested plant spec ...

Abstract:
... The eco-compatibility of the glycine-derived polyamidoamine M-GLY, chosen as the benchmark for water-soluble polyamidoamines, was investigated by means of the seed germination test using watercress seeds. The percent germinated seeds and their root elongation were measured, and the corresponding germination index (GI) calculated for each set of data obtained by incubating the seeds with M-GLY aque ...

Abstract:
... MAIN CONCLUSION: Extracellular ATP level induced a transient increase during germination of Arabidopsis seeds, and extracellular ATP could negatively regulate the seed germination by its receptor, DORN1. Extracellular ATP (exATP) acts as a signal molecule for regulating growth, development, and responses of plants to external environments. In this study, we investigated the possible involvement of ...

Abstract:
... Carbon monoxide (CO) represents one of key gasotransmitter molecules involved in transduction of various signals necessary for regulation of many functions of living organisms. The review considers peculiarities of CO synthesis in plants and briefly characterizes heme oxygenase as a chief enzyme catalyzing the formation of carbon monoxide. Participation of CO in the processes of growth and develop ...
seedgermination, etc ; biosynthesis; gibberellic acid; imbibition; plant growth; seedlings; tomatoes; vigor; Show all 8 Subjects
Abstract:
... Priming of seed is intended to reduce the time to germination through activation of pre-germinative processes. Seed priming is controlled hydration followed by a drying (dehydration) process. The physiological processes during hydration (imbibition) were studied in detail in tomato. In contrast, gibberellic acid changes during the dehydration phase were not studied in detail. We hypothesize that t ...

Abstract:
... Chilling injury poses a serious threat to seed emergence of spring-sowing maize in China, which has become one of the main climatic limiting factors affecting maize production in China. It is of great significance to mine the key genes controlling low-temperature tolerance during seed germination and study their functions for breeding new maize varieties with strong low-temperature tolerance durin ...

Abstract:
... SlDREB3 was identified as a ripening up-regulated gene of the AP2/ERF-domain family of transcription factors. Its manipulation affects processes primarily governed by ABA. It negatively regulates ABA responses in tomato by altering ABA levels/signaling and is, in turn, negatively regulated by ABA. SlDREB3 over-expression lines show higher transcript levels of the ABA metabolism genes CYP707A3 and ...

Abstract:
... Azo compounds represent the most diverse group of colorants widely employed in industrial sectors. Being highly toxic and recalcitrant compound, azo dyes pose a threat to plants, animals, and humans. In the present report, bio-decolorization of azo dye, reactive black 5, was evaluated by newly isolated Priestia sp. RA1. Strain RA1 was able to decolorize 97% of 100 ppm reactive black 5 in 60 h. Spe ...

Abstract:
... Poor germination and the length of time required for the growth of seedlings appropriate for planting in the farm affect the cultivation of medicinal plants such as yarrow (Achillea millefolium L). This study investigated the abilities of different concentrations of gibberellic acid (GA₃) and potassium nitrate (KNO₃), mechanical scarification, and hydropriming to improve seed germination and dorma ...

Abstract:
... The root parasitic weed broomrapes, Phelipanche spp., cause severe damage to agriculture all over the world. They have a special host-dependent lifecycle and their seeds can germinate only when they receive chemical signals released from host roots. Our previous study demonstrated that 2-phenylethyl isothiocyanate is an active germination stimulant for P. ramosa in root exudates of oilseed rape. I ...

To compare C. monogyna seed germination and the seedling emergence of two populations from Quchan and Bardaskan in Khorasan-e-Razavi-I province in north east of Iran, experiments were carried out. From the results, the highest germination percentages for Quchan (98%) and Bardaskan (97%) populations were observed at alternating 25/15 and 30/20 °C day/night temperatures, respectively. Germination pe ...

Abstract:
... Seed dormancy and germination are two distinct physiological processes in the life cycle of plants. Dormancy alleviation and the attendant transition to seed germination are critical developmental events that are regulated by endogenous and ambient cues. ROS, Ca²⁺ (and Ca²⁺-dependent) signals, and phytohormones, such as ABA and GA, are significant endogenous cues. On the other hand, temperature, l ...

Abstract:
... Arabidopsis thaliana seed germination is marked by extensive translational control at two critical phase transitions. The first transition refers to the start of hydration, the hydration translational shift. The second shift, the germination translational shift (GTS) is the phase between testa rupture and radicle protrusion at which the seed makes the all or nothing decision to germinate. The mech ...

AFP1 interacts with ABI5 and negatively regulates the abscisic acid (ABA) signaling by accelerating ABI5's degradation during the seed germination phase in Arabidopsis, but the underlying mechanism remains unclear. Moreover, the molecular basis of the interaction between AFP1 homologs and ABI5 has yet to be elucidated. In this study, the patterns of their interactions with ABI5 were investigated i ...
