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 ...

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 ...

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:
... 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 ...

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 ...

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 ...
