Sexual pheromone modulates the frequency of cytosolic Ca2+ bursts in Saccharomyces cerevisiae
(American Society for Cell Biology, 2016-12)
Transient and highly regulated elevations of cytosolic Ca2+ control a variety of cellular processes. Bulk measurements using radioactive Ca2+ and the luminescent sensor aequorin have shown that in response to pheromone, ...
Male Sexual Behavior and Pheromone Emission Is Enhanced by Exposure to Guava Fruit Volatiles in Anastrepha fraterculus
(Public Library of Science, 2015-04)
Background: Plant chemicals can affect reproductive strategies of tephritid fruit flies by influencing sex pheromone communication and increasing male mating competitiveness. Objective and Methodology: We explored whether ...
Identification of Volatile Emissions from Platypus mutatus (=sulcatus) (Coleoptera: Platypodidae) and Their Behavioral Activity
(Entomological Society of America, 2005-10)
We report here the identification and biological activity of volatile compounds emitted by male Platypus mutatus (=sulcatus) Chapuis while boring galleries in living Poplar (Populus deltoides) trees. Headspace analysis ...
Interaction between sexual communication functions leads to reproductive interference in two syntopic scorpion species
(Academic Press Ltd - Elsevier Science Ltd, 2021-11)
Sexual communication in mate choice scenarios involves nonmutually exclusive functions: species recognition, mate location and mate assessment. Most studies on sexual communication in mate choice have focused on female ...
Mitotic and pheromone-specific intrinsic polarization cues interfere with gradient sensing in Saccharomyces cerevisiae
(National Academy of Sciences, 2020-03)
Polarity decisions are central to many processes, including mitosis and chemotropism. In Saccharomyces cerevisiae, budding and mating projection (MP) formation use an overlapping system of cortical landmarks that converges ...
Pheromone-induced morphogenesis improves osmoadaptation capacity by activating the HOG MAPK pathway
(American Association for the Advancement of Science, 2013-04)
Environmental and internal conditions expose cells to a multiplicity of stimuli whose consequences are difficult to predict. We investigate the response to mating pheromone of yeast cells adapted to high osmolarity. Events ...
Mating, but Not Male Accessory Gland Products, Changes Female Response to Olfactory Cues in Anastrepha Fruit Flies
(Frontiers Media S.A., 2021-09)
Copulation and/or ejaculate components can alter female physiological state and female post-mating behavior. The objective of the present study was to determine if copulation and male reproductive accessory gland products ...
Pheromone emission patterns and courtship sequences across distinct populations within Anastrepha fraterculus (Diptera-Tephitidae) cryptic species complex – CORRIGENDUM
(Cambridge University Press, 2019-01)
exual behavioural isolation can result from sexual selection and represents a relevant factor associated with the speciation process. We analysed the pheromone emission pattern and the courtship of males of five different ...
Mechanical stress impairs pheromone signaling via Pkc1-mediated regulation of the MAPK scaffold Ste5
(Rockefeller University Press, 2019-09)
Cells continuously adapt cellular processes by integrating external and internal signals. In yeast, multiple stress signals regulate pheromone signaling to prevent mating under unfavorable conditions. However, the underlying ...
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
(Wiley Blackwell Publishing, Inc, 2015-08)
1- The avoidance of parasitized or infested hosts, which is a common phenomenon in parasitic wasps and phytophagous insects, may act both intra- and interspecifically. Most studies on chemically-mediated avoidance of ...
