In nature, organisms have to cope with constantly changing environments. In certain conditions, it may be advantageous for the parents to pass on information about the environment, or resources to their offspring. Such transfers are known as parental effects, and they are well documented in plants and animals, but not in other eukaryotes, such as fungi. Many fungi disperse through spores, and fungal spores can potentially carry information or resources to the next generation. Understanding parental effects and their evolutionary consequences in fungi is of vital importance as they perform crucial ecosystem functions. In this study, we investigated whether parental effects are present in the filamentous fungus Neurospora crassa, how long do they last, whether the effects are adaptive, and what is their mechanism. We performed a fully factorial match/mismatch experiment for a good and a poor quality environment, in which we measured the initial growth of strains that experienced either a matched or mismatched environment in their previous generation. We found a strong silver-spoon effect in initial mycelium growth, which lasted for one generation, and increased fitness during competition experiments. By using deletion mutants that lacked key genes in epigenetic processes, we show that epigenetic mechanisms are not involved in this effect. Instead, we show that spore glycogen content, glucose availability and a radical transcription shift in spores are the main mechanisms behind this parental effect.

Epigenetic Control of Phenotypic Plasticity in the Filamentous Fungus Neurospora crassa
Kronholm, Ilkka; Johannesson, Hanna; Ketola, Tarmo (Genetics Society of America, 2016)Phenotypic plasticity is the ability of a genotype to produce different phenotypes under different environmental or developmental conditions. Phenotypic plasticity is a ubiquitous feature of living organisms, and is ... -
Quantitative genetics of temperature performance curves of Neurospora crassa
Moghadam, N.N.; Sidhu, K.; Summanen, P.A.M.; Ketola, T.; Kronholm, I. (Wiley, 2020)Earth's temperature is increasing due to anthropogenic CO2 emissions; and organisms need either to adapt to higher temperatures, migrate into colder areas, or face extinction. Temperature affects nearly all aspects of an ... -
Marked Neurospora crassa Strains for Competition Experiments and Bayesian Methods for Fitness Estimates
Kronholm, Ilkka; Ormsby, Tereza; McNaught, Kevin J.; Selker, Eric U.; Ketola, Tarmo (Genetics Society of America, 2020)The filamentous fungus Neurospora crassa, a model microbial eukaryote, has a life cycle with many features that make it suitable for studying experimental evolution. However, it has lacked a general tool for estimating ... -
Chromatin structure influences rate and spectrum of spontaneous mutations in Neurospora crassa
Villalba de la Peña, Mariana; Summanen, Pauliina A. M.; Liukkonen, Martta; Kronholm, Ilkka (Cold Spring Harbor Laboratory, 2023)While mutation rates have been extensively studied, variation in mutation rates throughout the genome is poorly understood. To understand patterns of genetic variation, it is important to understand how mutation rates vary. ... -
Silver-spoon effects increase competitive fitness in Neurospora crassa
Summanen, Pauliina (2020)Muuttuviin ympäristöoloihin sopeutumista helpottavat työkalut ovat eliöille tärkeitä, koska muutoksen mahdollisuus on luonnossa jatkuvasti läsnä. Näiden työkalujen joukkoon kuuluvat ylisukupolviset efektit, jotka voivat ...
