Effect of BvAgNP on growth, development, and glyoxalase gene expression analysis in Mammillaria bombycina and Selenicereus undatus.

Background: Silver nanoparticles (AgNPs) have been used in plant tissue culture as growth stimulants, promoting bud initiation, germination, and rooting. In prior studies, AgNPs were synthesized and characterized by green synthesis using extracts from Beta vulgaris var. cicla (BvAgNP), and their functionality as seed disinfectant and antimicrobial was verified.

Identification and Profiling Analysis of microRNAs in Guava Fruit ( L.) and Their Role during Ripening.

The guava ( L.) is a climacteric fruit with an accelerated post-harvest overripening. miRNAs are small RNA sequences that function as gene regulators in eukaryotes and are essential for their survival and development.

Antimicrobial activity of the Flo peptide produced in Scenedesmus acutus and Nannochloropsis oculata.

The continuous increase of bacterial pathogen resistance to conventional antibiotics has challenged the research community to develop new antimicrobial strategies. Antimicrobial peptides (AMP) are a promising alternative to combat multidrug-resistant strains compared to conventional antibiotics because of their biocompatibility. In the present study, the Flo peptide, an AMP from the Moringa oleifera tree, was expressed in the chloroplast of the microalgae Nannochloropsis oculata and Scenedesmus acutus.

Validation of the color graduation scale in the optical nerve photograph, an alternative for qualitative classification.

Background: To validate objectively the proposed Teherán-Morales's color grading scale, comparing to the subjective readings of specialists in optic nerve photography.

Methods: Concordance study and diagnostic tests, in which 150 photographs of the optic nerve were evaluated, from three groups, glaucomatous neuropathy, neuropathy of other origin and control group with the Teherán-Morales's color scale and the analysis of three experts in optic nerve. Spearman's Rho correlation was performed between both analysis methods.

De Novo Transcriptome of (Cactaceae) under In Vitro Conditions and Identification of Glyoxalase Genes.

is a cactus distributed in the central region of Mexico. Cactaceae have the particularity of surviving drought and high temperatures, which is why in vitro propagation studies have been carried out successfully to preserve this species and use it as a study model in cacti. In this contribution, a de novo transcriptome of was produced under in vitro conditions for the identification and expression of genes related to abiotic stress.
