Cytological Identification of Chromosomal Rearrangements in Doritaenopsis and Phalaenopsis
(Journal of International Cooperation (Taiwan) 2(1): 1-11, 2007-09-01)
This study investigated the impact of gross chromosomal rearrangements, specifically translocations and inversions, on the division of pollen mother cells in hybrids Dtps. Queen Beer, Dtps. Sinica Sunday, Dtps. Sweet ...
Rise of the clones: apomixis in plant breeding
(Flowering plants: classification, characteristics and breeding, Chapter: 4, Publisher: Nova Publishers, Editors: J.J. Tellstone, pp.97-117, 2011)
In flowering plants the transfer of traits from one generation to the other involves fertilization of female gametophyte with sperm cells delivered by pollen tube, and the subsequent reassortment of traits (alleles) in the ...
Meiotic Chromosome Behavior and Capsule Setting in Doritaenopsis Hybrids
(J. AMER. SOC. HORT. SCI. 133(1):107–116. 2008, 2008-10-06)
The development of new cultivars in Doritaenopsis Guillaum. & Lami orchids is often hindered by factors such as low seed count in hybrids. Cytological study may offer the ability to develop new hybrids by revealing cultivars ...
Genética y ecología de la regeneración de robledables fragmentados en Costa Rica: efecto de mamíferos pequeños en la disperción de semillas y el establecimiento de plántulas.
(2011-08-09)
Este proyecto estudió el papel de los mamíferos pequeños (especialmente roedores) en la dinámica de la regeneración de los bosques de roble en las zonas altas de Costa Rica, específicamente en el Cerro de la Muerte. Los ...

(2011-07-09)
Estimar la distancia del flujo de polen y la distribución de la fertilidad masculina y femenina de Caryocar costarricense en una población de la Península de Osa de Costa Rica, con el fin de evaluar las características ...
Pollen Meiotic Behavior in Relation to Phalaenopsis Breeding
(Acta Horticulturae 878: 139-144 (2010), 2010)
The breeding of Phalaenopsis orchids involves the cross-pollination of two selected parental plants. Parents with re gular meiotic behavior can often produce seeds successfully. Currently most Phalaenopsis hybrids are ...
Arabidopsis CHROMOSOME TRANSMISSION FIDELITY 7 (AtCTF7/ECO1) is required for DNA repair, mitosis and meiosis
(The Plant Journal 75: 927–940, 2013-06-10)
The proper transmission of DNA in dividing cells is crucial for the survival of eukaryotic organisms. During cell division, faithful segregation of replicated chromosomes requires their tight attachment, known as sister ...
