Fruit growth is mediated by cell division and expansion. In tomato, the model for fleshy fruit development, both processes are tightly linked to changes in gene expression, including transcriptional regulation and RNA processing. While several transcription factors are implicated in fruit developmental programs, the role of splicing regulators remains largely unexplored. Expression profiling of splicing-related genes revealed...

The leaf surface, known as the phylloplane, presents an oligotrophic and heterogeneous environment due to its topography and uneven distribution of resources. Although it is a challenging environment, leaves support abundant bacterial communities that are spatially structured. However, the factors influencing these spatial distribution patterns are not well understood. To study the changes in population density and spatial dis...

Main conclusion Unlike Arabidopsis thaliana , defenses of Arabidopsis lyrata against Pieris brassicae larval feeding are not primable by P. brassicae eggs. Thus, egg primability of plant anti-herbivore defenses is not phylogenetically conserved in the genus Arabidopsis . Abstract While plant anti-herbivore defenses of the annual species Arabidopsis thaliana were shown to be primable by Pieris brassicae eggs, the primability of...

Summary A caryochloris marina is a symbiotic species of cyanobacteria that is capable of utilizing far‐red light. We report the characterization of the phages A ‐ HIS 1 and A ‐ HIS 2, capable of infecting A caryochloris . Morphological characterization of these phages places them in the family S iphoviridae . However, molecular characterization reveals that they do not show genetic similarity with any known siphoviruses. While...
