Species of the complex cause postbloom fruit drop of citrus and anthracnose fruit rot of strawberries. produces acervuli in diseased citrus flowers and strawberry fruit, surviving asymptomatically on vegetative tissues. Previous studies have suggested that dispersal mechanisms other than windblown rain may be involved in dispersal of conidia of sensu lato.

Ex situ conservation of plant genetic resources (PGR) plays a crucial role in sustainable growth and development, as highlighted by the Global Strategy for Plant Conservation (GSPC). Seed genebanks, a key component of ex situ conservation, have been instrumental in preserving plant diversity. However, challenges arise with the conservation of non-orthodox (recalcitrant and intermediate) seeds and vegetative tissues, which are not amenable to storage in traditional genebanks at temperatures of -20°C.

Iron plays a prominent role in various biological processes and is an essential element in almost all organisms, including plant-pathogenic fungi. As a transition element, iron occurs in two redox states, Fe and Fe, the transition between which generates distinct reactive oxygen species (ROS) such as HO, OH anions, and toxic OH· radicals. Thus, the redox status of Fe determines ROS formation in pathogen attack and plant defense and governs the outcome of pathogenic interactions.

DNA N6-methyladenine (6mA) is a potential epigenetic mark involved in gene transcription in eukaryotes, yet the regulatory mechanism governing its methyltransferase (MTase) activity remains obscure. Here, we exploited the 6mA MTase AMT1 to elucidate its auto-regulation in the unicellular eukaryote Tetrahymena thermophila. The detailed endogenous localization of AMT1 in vegetative and sexual stages revealed a correlation between the 6mA reestablishment in the new MAC and the occurrence of zygotically expressed AMT1.

The utilization of nitrogen (N) is crucial for the optimal growth and development of plants. As the dominant form of nitrogen in temperate soil, nitrate (NO) is absorbed from the soil and redistributed to other organs through NO transporters (NRTs). Therefore, exploration of the role of NRTs in response to various NO conditions is crucial for improving N utilization efficiency (NUE).
