--- _id: '5908' abstract: - lang: eng text: The interorganelle communication mediated by membrane contact sites (MCSs) is an evolutionary hallmark of eukaryotic cells. MCS connections enable the nonvesicular exchange of information between organelles and allow them to coordinate responses to changing cellular environments. In plants, the importance of MCS components in the responses to environmental stress has been widely established, but the molecular mechanisms regulating interorganelle connectivity during stress still remain opaque. In this report, we use the model plant Arabidopsis thaliana to show that ionic stress increases endoplasmic reticulum (ER)–plasma membrane (PM) connectivity by promoting the cortical expansion of synaptotagmin 1 (SYT1)-enriched ER–PM contact sites (S-EPCSs). We define differential roles for the cortical cytoskeleton in the regulation of S-EPCS dynamics and ER–PM connectivity, and we identify the accumulation of phosphatidylinositol 4,5-bisphosphate [PI(4,5)P2] at the PM as a molecular signal associated with the ER–PM connectivity changes. Our study highlights the functional conservation of EPCS components and PM phosphoinositides as modulators of ER–PM connectivity in eukaryotes, and uncovers unique aspects of the spatiotemporal regulation of ER–PM connectivity in plants. article_processing_charge: No article_type: original author: - first_name: Eunkyoung full_name: Lee, Eunkyoung last_name: Lee - first_name: Steffen full_name: Vanneste, Steffen last_name: Vanneste - first_name: Jessica full_name: Pérez-Sancho, Jessica last_name: Pérez-Sancho - first_name: Francisco full_name: Benitez-Fuente, Francisco last_name: Benitez-Fuente - first_name: Matthew full_name: Strelau, Matthew last_name: Strelau - first_name: Alberto P. full_name: Macho, Alberto P. last_name: Macho - first_name: Miguel A. full_name: Botella, Miguel A. last_name: Botella - first_name: Jiří full_name: Friml, Jiří id: 4159519E-F248-11E8-B48F-1D18A9856A87 last_name: Friml orcid: 0000-0002-8302-7596 - first_name: Abel full_name: Rosado, Abel last_name: Rosado citation: ama: Lee E, Vanneste S, Pérez-Sancho J, et al.

Despite numerous studies on the effect of nectar robbing on components of plant fitness, its contribution to reproductive isolation is unclear. We experimentally tested the impact of different pollinator strategies in a natural hybrid zone between two subspecies of Antirrhinum majus with alternate flower colour guides. On either side of a steep cline in flower colour between Antirrhinum majus pseudomajus (magenta) and A. m. striatum (yellow), we quantified the behaviour of all floral visitors at different time points during the flowering season. Using long-run camera surveys, we quantify the impact of nectar robbing on the number of flowers visited per inflorescence and the flower probing time. We further experimentally tested the effect of nectar robbing on female reproductive success by manipulating the intensity of robbing. While robbing increased over time the number of legitimate visitors tended to decrease concomitantly. We found that the number of flowers pollinated on a focal inflorescence decreased with the number of prior robbing events. However, in the manipulative experiment, fruit set and fruit volume did not vary significantly between low robbing and control treatments. Our findings challenge the idea that robbers have a negative impact on plant fitness through female function. This study also adds to our understanding of the components of pollinator-mediated reproductive isolation and the maintenance of Antirrhinum hybrid zones. article_processing_charge: No author: - first_name: Christophe full_name: Andalo, Christophe last_name: Andalo - first_name: Monique full_name: Burrus, Monique last_name: Burrus - first_name: Sandrine full_name: Paute, Sandrine last_name: Paute - first_name: Christine full_name: Lauzeral, Christine last_name: Lauzeral - first_name: David full_name: Field, David id: 419049E2-F248-11E8-B48F-1D18A9856A87 last_name: Field orcid: 0000-0002-4014-8478 citation: ama: Andalo C, Burrus M, Paute S, Lauzeral C, Field D.

A circle graph is an intersection graph of chords of a circle. We study the partial representation extension problem for circle graphs, where the input consists of a graph G and a partial representation R′ giving some predrawn chords that represent an induced subgraph of G. The question is whether one can extend R′ to a representation R of the entire graph G, that is, whether one can draw the remaining chords into a partially predrawn representation to obtain a representation of G. Our main result is an O(n3) time algorithm for partial representation extension of circle graphs, where n is the number of vertices. To show this, we describe the structure of all representations of a circle graph using split decomposition. This can be of independent interest. article_processing_charge: No article_type: original author: - first_name: Steven full_name: Chaplick, Steven last_name: Chaplick - first_name: Radoslav full_name: Fulek, Radoslav id: 39F3FFE4-F248-11E8-B48F-1D18A9856A87 last_name: Fulek orcid: 0000-0001-8485-1774 - first_name: Pavel full_name: Klavík, Pavel last_name: Klavík citation: ama: Chaplick S, Fulek R, Klavík P.
