Abstract Glucose modulates plant metabolism, growth, and development. In Arabidopsis (Arabidopsis thaliana), Hexokinase1 (HXK1) is a glucose sensor that may trigger abscisic acid (ABA) synthesis sensitivity to mediate glucose-induced inhibition of seedling Here, we show the intensity short-term responses can vary with ABA activity. We report transient (2 h/4 h) repression by 2% AtbZIP63, gene encoding basic-leucine zipper (bZIP) transcription factor partially involved in Snf1-related kinase...
Highlights•A screen for suppressors of plant lst8 mutants identifies the AtYAK1 kinase•The kinase interacts with RAPTOR and is phosphorylated by TOR•AtYAK1 disruption reduces transcriptional metabolic changes in mutants•The ABA hypersensitivity reverted atyak1 mutationsSummaryThe target rapamycin (TOR) a conserved energy sensor that regulates growth response to environmental cues. However, little known about TOR signaling pathway plants. We used Arabidopsis lines affected lethal SEC13...
In nature, plants are simultaneously exposed to different abiotic (e.g., heat, drought, and salinity) biotic bacteria, fungi, insects) stresses. Climate change anthropogenic pressure expected intensify the frequency of stress factors. Although well equipped with unique common defense systems protecting against stressors, they may compromise their growth development for survival in such challenging environments. Ionizing radiation is a peculiar factor capable causing clustered damage....
Abstract At low intensity, certain stress conditions may have a positive effect on growth and development of plants (eustress). Growth stimulation barley after gamma irradiation seeds in doses was observed as an increase root shoot lengths. Hydrogen peroxide concentrations shoots irradiated were significantly higher than control, while the opposite roots. To elucidate molecular basis seeds, we performed transcriptomic analysis embryos at different stages seed germination. The data correlated...
Adjustment to energy starvation is crucial ensure growth and survival. In Arabidopsis thaliana (Arabidopsis), this process relies in part on the phosphorylation of circadian clock regulator bZIP63 by SUCROSE non-fermenting RELATED KINASE1 (SnRK1), a key mediator responses low energy. We investigated effects mutations plant carbon (C) metabolism growth. Results from phenotypic, transcriptomic metabolomic analysis mutants prompted us investigate starch accumulation pattern expression genes...
Organisms can rapidly mitigate the effects of environmental changes by changing their phenotypes, known as phenotypic plasticity. Yet, little is about temperature-mediated plasticity traits that are directly linked to plant fitness such flower size. We discovered substantial genetic variation in size temperature both among selfing Arabidopsis thaliana and outcrossing A. arenosa individuals collected from a natural growth habitat. Genetic analysis using panel 290 accession mutant lines...
Chronic ionising radiation exposure is a main consequence of radioactive pollution the environment. The development functional genomics approaches coupled with morphological and physiological studies allows new insights into plant adaptation to life under chronic irradiation. Using morphological, reproductive, physiological, transcriptomic experiments, we evaluated way in which Arabidopsis thaliana natural accessions from Chernobyl exclusion zone recover low-dose acute high-dose...
In plants, sugars such as glucose act signalling molecules that promote changes in gene expression programmes impact on growth and development. Recent evidence has revealed the potential importance of controlling mRNA decay some aspects glucose-mediated regulatory responses suggesting a role microRNAs (miRNAs) these responses. order to get better understanding development modulation involving miRNA-related pathways, early seedling mutants impaired miRNA biogenesis (hyl1-2 dcl1-11) activity...
RNA sequencing (RNA-seq) has opened up the possibility of studying virtually any organism at whole transcriptome level. Nevertheless, absence a sequenced and accurately annotated reference genome may be an obstacle for applying this technique to non-model organisms, especially those with complex genome. While de novo assembly can circumvent problem, it is often computationally demanding. Furthermore, annotation Gene Ontology enrichment analysis without automatized system laborious task. Here...
Our understanding of the long-term consequences chronic ionising radiation for living organisms remains scarce. Modern molecular biology techniques are helpful tools researching pollutant effects on biota. To reveal phenotype plants growing under exposure, we sampled Vicia cracca L. in Chernobyl exclusion zone and areas with normal backgrounds. We performed a detailed analysis soil gene expression patterns conducted coordinated multi-omics analyses plant samples, including transcriptomics,...
The family Calliphoridae consists of myiasis-causing flies, including species economic, forensic, and medical importance. In this study, the complete control regions (CRs) mitochondrial DNA from 15 calliphorid were sequenced structurally characterized. CRs had a high content adenines (A) thymines (T) varied in length 854 to 2,018 bp, showing intraspecific variations sequence length. Two major domains identified: conserved domain containing blocks cis-regulatory structures that may be related...

Nitrogen (N) is fundamental to plant growth, development and yield. Genes underlying N utilization assimilation are well-characterized, but mechanisms underpinning plasticity of different phenotypes in response remain elusive. Here, using Arabidopsis thaliana accessions, we dissected the genetic architecture early late rosette diameter, flowering time yield, three levels soil. Furthermore, found that primary metabolites were related with plasticities studied traits. Genome-wide association...
