"Potato microtuber (MT) development through in vitro techniques are ideal propagules for producing high quality potato plants. MT formation is influenced by several factors, i.e., photoperiod, sucrose, hormones, and osmotic stress. We have previously developed a protocol of MT induction in medium with sucrose (8% w/v), gelrite (6g/L), and 2iP as cytokinin under darkness. To understand the molecular mechanisms involved, we performed a transcriptome-wide analysis. Here we show that 1715 up- and 1624 down-regulated genes were involved in this biological process. Through the protein–protein interaction (PPI) network analyses performed in the STRING database (v11.5), we found 299 genes tightly associated in 14 clusters. Two major clusters of up-regulated proteins fundamental for life growth and development were found: 29 ribosomal proteins (RPs) interacting with 6 PEBP family members and 117 cell cycle (CC) proteins. The PPI network of up-regulated transcription factors (TFs) revealed that at least six TFs–MYB43, TSF, bZIP27, bZIP43, HAT4 and WOX9–may be involved during MTs development. The PPI network of down-regulated genes revealed a cluster of 83 proteins involved in light and photosynthesis, 110 in response to hormone, 74 in hormone mediate signaling pathway and 22 related to aging."

Resilience of growing in arid and semiarid regions and a high capacity of accumulating sugar-rich biomass with low lignin percentages have placed Agave species as an emerging bioen-ergy crop. Although transcriptome sequencing of fiber-producing agave species has been explored, molecular bases that control wall cell biogenesis and metabolism in agave species are still poorly understood. Here, through RNAseq data mining, we reconstructed the cellulose biosynthesis pathway and the phenylpropanoid route producing lignin monomers in A. tequilana, and evaluated their expression patterns in silico and experimentally. Most of the orthologs retrieved showed differential expression levels when they were analyzed in different tissues with contrasting cellulose and lignin accumulation. Phylogenetic and structural motif analyses of putative CESA and CAD proteins allowed to identify those potentially involved with secondary cell wall formation. RT-qPCR assays revealed enhanced expression levels of AtqCAD5 and AtqCESA7 in parenchyma cells associated with extraxylary fibers, suggesting a mechanism of formation of sclerenchyma fibers in Agave similar to that reported for xylem cells in model eudicots. Overall, our results provide a framework for un-derstanding molecular bases underlying cell wall biogenesis in Agave species studying mechanisms involving in leaf fiber development in monocots. © 2022 by the authors.

"En México la pesquería de abulón amarillo (Haliotis corrugata) se ha visto fuertemente afectada por la sobrepesca y factores ambientales. En este contexto, la repoblación de los bancos silvestres mediante liberación de larvas o juveniles producidos en laboratorio se ha vislumbrado como una alternativa para incrementar la producción. Cualquier programa de repoblamiento debe considerar una estrategia de manejo genético que evite la pérdida de diversidad genética y que permita dar seguimiento del pedigrí de los individuos producidos en laboratorio y liberados posteriormente en los bancos naturales. Uno de los requisitos de los marcadores moleculares tipo microsatélites empleados para la asignación de parentesco en análisis de pedigrí es su conformación al modelo de herencia mendeliana. En el presente estudio se analizaron larvas veliger de H. corrugata de tres familias no emparentadas (cada una de hermanos completos) con 11 loci microsatélites para evaluar si sus clases genotípicas se ajustaban a las proporciones esperadas bajo herencia mendeliana. Las proporciones genotípicas de ocho loci (Hco15, Hco19, Hco22, Hco47-2, Hco47-3, Hco194, Hka3 y Hka56) se ajustaron a las proporciones mendelianas esperadas, dos loci (Hco47-1 y Hco97) mostraron desviaciones significativas (P<0,05) y en un locus (Hco16) no se pudo comprobar segregación mendeliana. Para análisis de parentesco futuros en esta especie se recomienda el uso de un grupo de al menos seis loci en el cual deben incluirse Hco19, Hco22, Hco47-2 y Hka3 debido a sus moderados a altos polimorfismos."

"In Mexico, the pink abalone (Haliotis corrugata) fishery has been strongly affected by overfishing and environmental factors. In this context, reseeding of natural beds through the release of hatchery produced larvae or juveniles, has been envisioned as an alternative to increase production. Any reseeding program should take in account a genetic management strategy, which avoids the loss of genetic diversity and enables to follow the pedigree of hatchery produced individuals being released in the natural beds. One of the requisites of microsatellites as molecular markers for parentage assignment is their agreement to Mendelian inheritance model. In the present study, Haliotis corrugata veliger larvae from three unrelated families (of fullsibs each), were analyzed with 11 microsatellite loci, to assess if their genotypic classes were in agreement to expected ratios under Mendelian inheritance. The genotypic ratios of eight loci (Hco15, Hco19, Hco22, Hco47-2, Hco47-3, Hco194, Hka3, and Hka56) were in agreement with Mendelian expected ratios, two loci (Hco47-1 and Hco97) showed significant deviations (P<0.05), and in one locus (Hco16) Mendelian segregation could not be demonstrated. From the results we suggest the use a group of at least 6 loci in subsequent parentage analyses in which loci Hco19, Hco22, Hco47-2 and Hka3 should be included because their moderate to high polymorphisms."

APLICACIÓN DE METAHEURÍSTICAS EN EL PROBLEMA DE ACOMODO DE PATRONES DE CORTE EN MATERIALES FINITOS

Anabel Rodríguez Rodríguez (2023, [Tesis de doctorado])

"En la presente investigación se resuelve el problema de optimización de acomodo de patrones de corte en materiales finitos mediante el uso de estrategias metaheurísticas con la finalidad de aprovechar el material de acomodo y minimizar el desperdicio. Específicamente se implementó un algoritmo genético que al inicio genera soluciones aleatorias que forman la población inicial. La misma está compuesta por individuos o soluciones que son una combinación de patrones que se acomodan dentro del material de manera que se obtenga el menor desperdicio. Durante el proceso evolutivo estas soluciones aleatorias se someten a los operadores genéticos: selección, cruce y mutación, para encontrar nuevas soluciones que hereden la información genética de sus antecesores y evolucionen o mejoren en cada generación para obtener el menor desperdicio posible."
