Enrichment metabolomics analyses showed that AA metabolic pathways were mostly changed by the treatments, with reduced amination activity in roots most likely due to a shift from the biosynthesis of common AA to γ-amino butyric acid, and the root metabolome differed between AMF and NAT but not AMF+PGPR and AMF or NAT.
Molecular Responses to Small Regulating Molecules against Huanglongbing Disease
Molecule data encourage long-term application of treatments that combine these regulating molecules in field trials to HLB disease beneficially, and upregulated key genes involved in carbohydrate metabolism such as sucrose-phosphate synthase, sucrose synthases, starch synthase and α-amylase.

Key RPW-modulated genes involved in innate response mediated by hormone crosstalk were observed belonging to auxin, jasmonate and salicylic acid (SA) pathways, and some WRKYs were clearly induced.

The hypothesis is that, in the present study, AM symbiosis did not increase the plant tolerance to salt stress but instead generated a condition in which plants were subjected to a level of salt stress lower than that of non-mycorrhizal plants.

A proteomic analysis of mature leaves of two Citrus genotypes with well-known differing tolerances to HLB showed that four glutathione-S-transferases were upregulated in Volkameriana and not in Navel orange, and upregulation of proteins involved in radical ion detoxification should be considered as an important mechanism of increased tolerance to H LB.

The evolutionary history of plant TUTases is described and the diverse molecular functions of uridylation during RNA degradation processes in plants are summarized, which outline key points of future research.

Insight is provided into the post-transcriptional mechanisms of wheat responses to water deficit in relation to mycorrhizal symbiosis as well as water deficit-modulated in roots irrespective of AMF treatment.

This work represents one of the first genome wide characterization of MIR genes in durum wheat, identifying leaf and root tissue-specific microRNAs and shows significant overrepresented gene categories in microRNA targets belonging to transcription factors, phenylpropanoids, oxydases, and lipid binding-protein.
A microarray analysis highlights the role of tetrapyrrole pathways in grapevine responses to “stolbur” phytoplasma, phloem virus infections and recovered status
The recovered plants showed that the transcripts involved in ATP synthesis and amino acid metabolism, secondary metabolism and biotic stress-related pathways increased, and recovery was associated with tetrapyrrole pathway repression.
Seasonal patterns in butterfly abundance and species diversity in five characteristic habitats in Sites of Community Importance in Sicily (Italy)
The results of several diversity indexes suggest that ampelodesmos prairie has an important ecological role, as it supports butterfly abundance and species diversity.
