Arabidopsis Qc‑SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation
(2015-10-01)Pollen tubes are rapidly growing specialized structures that elongate in a polar manner. They play a crucial role in the delivery of sperm cells through the stylar tissues of the flower and into the embryo sac, where the ... -
Dry-season leaf flushing of Enterolobium cyclocarpum (ear-pod tree): above- and belowground phenology and water relations
(2007-11)Above- and belowground phenology and water relations of Enterolobium cyclocarpum Jacq. trees in the dry forest of Santa Rosa National Park, Costa Rica were studied during two consecutive phenological cycles, from November ... -
In favor of establishment: chromatid cohesion in plants
(2017-05-23)In eukaryotic organisms, the correct regulation of sister chromatid cohesion, whereby sister chromatids are paired and held together, is essential for accurate segregation of the sister chromatids and homologous chromosomes ... -
Insights Into the Role of Ubiquitination in Meiosis: Fertility, Adaptation and Plant Breeding
(2018-10)Ubiquitination is a post-translational modification process that plays a central role in protein degradation in eukaryotic cell cell division, including meiosis. This modification affects different cellular processes on a ... -

(2013-06-26)Se comenta la situación de la escasez de agua, y la seguridad alimentaria y nutricional, en el Territorio Indígena de Matambú. -
Patogenicidad de tres hongos asociados a la muerte de plantas de fresa (Fragaria ananassa) y descripción ultraestructural del patosistema
(2022-08-03)Introducción. El cultivo de fresa (Fragaria ananassa) es importante en Costa Rica por su alta demanda como fruta fresca y para elaboración de mermeladas. En 2015 empezaron reportes de muerte de plantas, presumiblemen ... -
Reduced activity of Arabidopsis chromosome-cohesion regulator gene CTF7/ECO1 alters cytosine methylation status and retrotransposon expression
(2015-05-01)Multicellular organisms such as higher plants require timely regulation of DNA replication and cell division to grow and develop. Recent work in Arabidopsis has shown that chromosome segregation during meiosis and mitosis ... -
Relaciones hídricas en árboles del bosque tropical seco: el caso de Enterolobium cyclocarpum
(2011)Las relaciones hídricas en árboles de Enterolobium cyclocarpum del Parque Nacional Santa Rosa, Costa Rica, se estudiaron en diferentes momentos del curso diurno y a lo largo de dos ciclos fenológicos. La característica ... -
Reproductive biology and behavior of Doru taeniatum (Forficulidae)
(Revista de BioIogía Tropical 36(2B): 437-440, 1988., 1988)This study deals with the biology of Doru taeniatum, (Forficuüdae), particulary the habitat, feeding, reproduction, maternal care, and nymphal stages. The density of adults is higher in the older corn plants. The earwings ... -
The Opposing Actions of Arabidopsis CHROMOSOME TRANSMISSION FIDELITY7 and WINGS APART-LIKE1 and 2 Differ in Mitotic and Meiotic Cells
(2016-02-01)Sister chromatid cohesion, which is mediated by the cohesin complex, is essential for the proper segregation of chromosomes during mitosis and meiosis. Stable binding of cohesin with chromosomes is regulated in part by the ...
