Time Critical

Plants perceive and integrate information from the environment to time critical transitions in their life cycle. Some mechanisms underlying this quantitative signal processing have been described, whereas others await discovery. Seeds have evolved a mechanism to integrate environmental information by regulating the abundance of the antagonistically acting hormones abscisic acid (ABA) and gibberellin (GA). Here, we show that hormone metabolic interactions and their feedbacks are sufficient to create a bistable developmental fate switch in Arabidopsis seeds. A digital single-cell atlas mapping the distribution of hormone metabolic and response components revealed their enrichment within the embryonic radicle, identifying the presence of a decision-making center within dormant seeds. The responses to both GA and ABA were found to occur within distinct cell types, suggesting cross-talk occurs at the level of hormone transport between these signaling centers. We describe theoretically, and demonstrate experimentally, that this spatial separation within the decision-making center is required to process variable temperature inputs from the environment to promote the breaking of dormancy. In contrast to other noise-filtering systems, including human neurons, the functional role of this spatial embedding is to leverage variability in temperature to transduce a fate-switching signal within this biological system. Fluctuating inputs therefore act as an instructive signal for seeds, enhancing the accuracy with which plants are established in ecosystems, and distributed computation within the radicle underlies this signal integration mechanism.

The Relationship

The integration of the world economies is responsible for an increase in the number of cross-border mergers and acquisitions (M&A), together with the growing participation of companies from emerging countries in this type of investment. However, the area studies focus their analyses on the determinants, antecedents and profitability of the companies, leaving the effects of this type of business on the operational risk of the companies involved as a gap to be explored. To fill it, we used panel data regressions to identify the relationship between cross-border M&A and the operational risk of companies. The results indicate that acquiring companies based in emerging economies are the ones that suffer the most significant impacts on this type of business. As the implication, this study serves as a basis for the decision-making of the managers of the acquiring companies, being able to identify the risks of this activity and the ways of preventing them.
