Major transcriptomic differences are induced by warmer temperature conditions experienced during asexual and sexual reproduction in Fragaria vesca ecotypes

A major challenge for plants in a rapidly changing climate is to adapt rising temperatures. Some temperature conditions by generating an epigenetic memory that can be transmitted both meiotically and mitotically. Such memories may increase phenotypic variation global warming provide time adaptation occur through classical genetic selection. The goal of this study was understand how warmer experienced during sexual asexual reproduction affect the transcriptomes different strawberry ( Fragaria vesca ) ecotypes. We let four European F. ecotypes reproduce at two contrasting temperatures (18 28°C), either asexually stolon formation several generations, or sexually seeds (achenes). then analyzed transcriptome unfolding leaves, with emphasis on differential expression genes belonging machinery. For reproduced we found general transcriptomic response but less significant responses. predicted splicing isoforms important (e.g. SOC1, LHY, SVP homolog), significantly more differentially presented event variants following vs. reproduction. This difference could due stochastic character recombination meiosis creation erasure marks embryogenesis seed development. Strikingly, very few expressed were shared between ecotypes, perhaps because differ greatly genetically epigenetically. Genes related machinery predominantly upregulated 28°C downregulated after reproduction, indicating temperature-induced change affects differently types
