Genome-wide identification of gene families related to miRNA biogenesis in L. and their possible role during heat stress.

Mango is a popular tropical fruit that requires quarantine hot water treatment (QHWT) for postharvest sanitation, which can cause abiotic stress. Plants have various defense mechanisms to cope with stress; miRNAs mainly regulate the expression of these defense responses. Proteins involved in the biogenesis of miRNAs include DICER-like (DCL), ARGONAUTE (AGO), HYPONASTIC LEAVES 1 (HYL1), SERRATE (SE), HUA ENHANCER1 (HEN1), HASTY (HST), and HEAT-SHOCK PROTEIN 90 (HSP90), among others.

Trichoderma virens Big Ras GTPase-1, a molecular switch for transforming a mutualistic fungus to plants in a deleterious microbe.

Trichoderma spp. are ascomycete filamentous fungi widely distributed worldwide that establish mutualistic relationships with plants by antagonizing phytopathogens in the rhizosphere and colonizing the plant roots, hence, promoting plant growth and triggering the systemic resistance against phytopathogens. During the first stages of root colonization by Trichoderma, plants recognize the fungus as an invader by inducing the plant defense system, including the production of reactive oxygen species (ROS).

Endocarditis due to Candida albicans in an immunocompromised patient: A case report.

Background: Fungal endocarditis is a low-frequency disease with a challenging diagnosis, as it can be mistaken with bacterial endocarditis. Fungal endocarditis causes higher mortality rates in immunocompromised patients. In the clinical practice, the endocarditis caused by fungi represents up to 10% of all infectious endocarditis cases and has a mortality rate of nearly 50%.

A Novel Glutathione -Transferase Gtt2 Class (VpGSTT2) Is Found in the Genome of the AHPND/EMS Shrimp Pathogen.

Glutathione S-transferases are a family of detoxifying enzymes that catalyze the conjugation of reduced glutathione (GSH) with different xenobiotic compounds using either Ser, Tyr, or Cys as a primary catalytic residue. We identified a novel GST in the genome of the shrimp pathogen FIM- S1708, a bacterial strain associated with Acute Hepatopancreatic Necrosis Disease (AHPND)/Early Mortality Syndrome (EMS) in cultured shrimp. This new GST class was named Gtt2.

Molecular characterization and expression analysis of the chicken-type and goose-type lysozymes from totoaba (Totoaba macdonaldi).

Lysozymes play a key role in innate immune response to bacterial pathogens, catalyzing the hydrolysis of the peptidoglycan layer of bacterial cell walls. In this study, the genes encoding the c-type (TmLyzc) and g-type (TmLyzg) lysozymes from Totoaba macdonaldi were cloned and characterized. The cDNA sequences of TmLyzg and TmLyzc were 582 and 432 bp, encoding polypeptides of 193 and 143 amino acids, respectively.

Immune response of human cultured cells towards macrocyclic FePO and FePC bioactive cyclophane complexes.

Synthetic molecules that mimic the function of natural enzymes or molecules have untapped potential for use in the next generation of drugs. Cyclic compounds that contain aromatic rings are macrocyclic cyclophanes, and when they coordinate iron ions are of particular interest due to their antioxidant and biomimetic properties. However, little is known about the molecular responses at the cellular level.

Quality and PR gene expression of table grapes treated with ozone and sulfur dioxide to control fungal decay.

Background: Gaseous fumigants are commonly employed to control fungal decay of cold-stored grapes. So far it is not clear if these fumigants, besides the direct interaction against fungal structures, induce transcriptional responses of defensive markers. In order to contribute to understanding the mechanisms by which these fumigants exert their effect, we studied the influence of ozone (O3) and sulfur dioxide (SO2) on the decay caused by Botrytis cinerea, and the quality and expression of the defense-related genes chitinase, β-1,3-glucanase and phenylalanine ammonia-lyase (PAL) in the table grape cultivars 'Redglobe' and 'Sugraone'.
