Plant Sci
March 2024
Laboratorio de Genética Molecular, Epigenética, Desarrollo y Evolución de plantas, Instituto de Ecología, Universidad Nacional Autónoma de México, 3er Circuito Ext. Junto a J. Botánico, Ciudad Universitaria. UNAM, México D.F. 04510, Mexico. Electronic address:
The epigenetic complex Trithorax (TrxG) regulates gene transcription through post-translational histone modifications and is involved in a wide range of developmental processes. ULTRAPETALA1 (ULT1) is a SAND domain plant-exclusive TrxG protein that regulates the H3K4me3 active mark to counteract PcG repression. ULT1 has been identified to be involved in multiple tissue-specific processes.

December 2023
Departamento de Física Experimental, Instituto de Física, Universidad Nacional Autónoma de México, Circuito de La Investigación Científica, Ciudad Universitaria UNAM, Mexico City, 04510, Mexico.
Purpose: To evaluate the effect of reconstruction and noise removal algorithms on the accuracy and precision of iodine concentration (C) quantified with subtracted micro-computed tomography (micro-CT).
Procedures: Two reconstruction algorithms were evaluated: a filtered backprojection (FBP) algorithm and a simultaneous iterative reconstruction technique (SIRT) algorithm. A 3D bilateral filter (BF) was used for noise removal.

Asymmetric cell divisions are essential to generate different cellular lineages. In plants, asymmetric cell divisions regulate the correct formation of the embryo, stomatal cells, apical and root meristems, and lateral roots. Current knowledge of regulation of asymmetric cell divisions suggests that, in addition to the function of key transcription factor networks, epigenetic mechanisms play crucial roles.

Departamento de Radioterapia, Hospital Médica Sur, Toriello Guerra, Tlalpan, 14050, Cd Mx, Mexico.
Aim: To evaluate the state of graduate education in medical physics and progress in radiation oncology (RO) equipment in Mexico since 2000, when conferring degrees from two master's-degree programs in Medical Physics began.
Background: Medical physics is a Health Profession and there are international recommendations for education, training, and certification. Both programs follow these education guidelines.
Natural Root Cellular Variation in Responses to Osmotic Stress in Accessions.
Genes (Basel)
November 2019
Plant Molecular Genetic, Epigenetic, Development and Evolution laboratory. Ecology Institute. National Autonomous University of Mexico. 3er Circuito Ext. Junto a J. Botánico, Ciudad Universitaria. UNAM, Mexico City 04510, Mexico.
Article Synopsis
- Researchers studied genetic variation in plant roots in response to water stress, focusing on how different environmental conditions affect root growth.
- They discovered that osmotic stress reduced root growth and size but led to earlier cell differentiation without changing the stem cell area.
- Variations in root growth due to osmotic stress were seen among different plant accessions, with Sg-2 and Cvi-0 showing the most resilience, though gene expression didn’t explain the differences in sensitivity.
