Adaptive and maladaptive expression plasticity underlying herbicide resistance in an agricultural weed

Plastic phenotypic responses to environmental change are common, yet we lack a clear understanding of the fitness consequences of these plastic responses. Here, we use the evolution of herbicide resistance in the common morning glory (Ipomoea purpurea) as a model for understanding the relative importance of adaptive and maladaptive gene expression responses to herbicide. Specifically, we compare leaf gene expression changes caused by herbicide to the expression changes that evolve in response to artificial selection for herbicide resistance. We identify a number of genes that show plastic and evolved responses to herbicide and find that for the majority of genes with both plastic and evolved responses, plastic responses appear to be adaptive. We also find that selection for herbicide response increases gene expression plasticity. Overall, these results show the importance of adaptive plasticity for herbicide resistance in a common weed and that expression changes in response to strong environmental change can be adaptive.

“…Genomic information about the transcription factors that regulate the related-stress gene is still poor. It has been recently identified in Arabidosis thaliana, a nuclear protein, ATR7, as a novel regulator of oxidative stress that controlled oxidative and abiotic stress-related genes in the seeds [145]. Also, Xi et al [146] identified the At2S3 promoter as responsible for the overexpression of antioxidant proteins (Mn-SOD and total CAT activities) in seed related organs such as siliques, mature seeds, and early seedlings.…”

The Importance of Ion Homeostasis and Nutrient Status in Seed Development and Germination

Seed is the dissemination unit of plants initiating an important stage in the life cycle of plants. Seed development, comprising two phases: embryogenesis and seed maturation, may define the quality of sown seed, especially under abiotic stress. In this review we have focused on the recent advances in the molecular mechanisms underlying these complex processes and how they are controlled by distinct environmental factors regulating ion homeostasis into the seed tissues. The role of transporters affecting seed embryogenesis and first stages of germination as imbibition and subsequent radicle protrusion and extension were revised from a molecular point of view. Seed formation depends on the loading of nutrients from the maternal seed coat to the filial endosperm, a process of which the efflux is not clear and where different ions and transporters are involved. The clear interrelation between soil nutrients, presence of heavy metals and the ion capacity of penetration through the seed are discussed in terms of ion effect during different germination stages. Results concerning seed priming techniques used in the improvement of seed vigor and radicle emergence are shown, where the use of nutrients as a novel way of osmopriming to alleviate abiotic stress effects and improve seedlings yield is discussed. Novel approaches to know the re-translocation from source leaves to developing seeds are considered, as an essential mechanism to understand the biofortification process of certain grains in order to cope with nutrient deficiencies, especially in arid and semiarid areas. Finally, the role of new genes involved in hormone-dependent processes, oxidative response and water uptake into the seeds during their development or germination, have been described as plant mechanisms to deal with abiotic stresses.

“…It was possible to annotate 41 of the 68 genes with evidence of adaptive plasticity based on homology to Arabidopsis thaliana (Table S3). Some genes were connected to stress responses, like a homolog of ATR7, which regulates abiotic stress (Sujeeth et al 2020) , a homolog of PATL1 which is important for salt and freezing tolerance (Chu et al 2018;Zhou et al 2018) , a homolog of PHT4;6 which is important for salt tolerance (Cubero et al 2009) , an ortholog of P5CDH which is important for many abiotic stress responses (Sharma and Verslues 2010;Liu et al 2015;Ren et al 2018) and a homolog of AtPTPN, which contributes to drought stress in A. thaliana (Zhang et al 2020) . However, many genes identified as having adaptive plasticity did not have homologs with obvious links to processes important for herbicide or other stress responses (Table S3).…”

Plastic phenotypic responses to environmental change are common, yet we lack a clear understanding of the fitness consequences of these plastic responses. Here, we use the evolution of herbicide resistance in the common morning glory (Ipomoea purpurea) as a model for understanding the relative importance of adaptive and maladaptive gene expression responses to herbicide. Specifically, we compare leaf gene expression changes caused by herbicide spray to the expression changes that evolve in response to artificial selection for herbicide resistance. We identify a number of genes that show plastic and evolved responses to herbicide and find that for the majority of genes with both plastic and evolved responses, plastic responses appear to be adaptive. We also find that selection for herbicide response increases gene expression plasticity. Overall, these results show the importance of adaptive plasticity for herbicide resistance in a common weed and that expression changes in response to strong environmental change can be adaptive.
