ASPECTOS CELULARES Y MOLECULARES INVOLUCRADOS EN LA EVOLUCIÓN DE ESTRUCTURAS CRANEOFACIALES

Acta Odontológica Colombiana, 2012
La cabeza de los vertebrados ha sido considerada como una de las principales innovaciones en el proceso evolutivo de los vertebrados y de su distinción craneofacial con el resto de cordados no vertebrados. Muchas estructuras craneofaciales como dientes (pulpa y dentina), maxilares, cartílagos, esqueleto craneofacial y órganos sensoriales son derivadas ...

Mitochondrial β‐carbonic anhydrase is a conserved metabolic rheostat for branched‐chain amino acid catabolism and metabolic flexibility

New Phytologist, Volume 250, Issue 4, Page 2415-2427, May 2026.
Summary Carbonic anhydrases (CAs) are ubiquitous metalloenzymes that catalyze the reversible hydration of CO2, enabling fundamental processes in organisms across all domains of life. Among all CAs, the role of mitochondrial βCA remains poorly understood. Here, we identify a mitochondrial βCA, βCA6, as a key regulator of branched‐chain amino acid (BCAA)

AGP and EXO‐LIKE genes promote brassinosteroid‐dependent anisotropic growth

New Phytologist, Volume 250, Issue 4, Page 2384-2398, May 2026.
Summary The brassinosteroid pathway promotes anisotropic cell expansion; however, the effectors in this process remain unclear. Candidates include ARABINOGALACTAN PROTEIN (AGP) genes, which are prominent brassinosteroid‐responsive transcriptional targets, and EXORDIUM (EXO)‐LIKE (EXL) genes.

Equipped for success: genomes and metabolomes of the European Amanita muscaria are conserved in its novel South African range

New Phytologist, Volume 250, Issue 3, Page 1863-1883, May 2026.
Summary Plants and soils have been moved around the world for centuries, but invasive mushrooms receive scant attention. The Amanita muscaria species complex was introduced to South Africa in the context of forestry, but its origins, ecology and recent evolution are unstudied. We sequenced the genomes of 24 Northern and Southern Hemisphere A. muscaria,

Estudios moleculares de sialidasas de Trypanosomátidos : relación estructura/función

, 1999
La trans-sialidasa de Trypanosoma cruzi es una enzima cuya existencia fue postulada en 1985cuando se probó que este parásito intracelular de células de mamífero, posee ácido siálico conjugadoa sus propias moléculas de superficie. La trans-sialidasa fue posteriormente purificada, caracterizadaenzimáticamente y su gen clonado.

Imaging and genetic toolbox to study Arabidopsis embryogenesis

New Phytologist, Volume 250, Issue 3, Page 1483-1491, May 2026.
Summary Embryogenesis in the model plant Arabidopsis thaliana provides a framework for understanding how cell polarity and patterning coordinate with hormonal signalling to establish the plant body plan. Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines ...
