    • Arabidopsis CHROMOSOME TRANSMISSION FIDELITY 7 (AtCTF7/ECO1) is required for DNA repair, mitosis and meiosis 

      Bolaños Villegas, Pablo Alberto; Yang, Xiaohui; Wang, Huei-Jing; Juan, Chien-Ta; Chuang, Min-Hsiang; Makaroff, Christopher A.; Jauh, Guang-Yuh (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 ...
    • Caracterización de productores de hortalizas orgánicas distribuidas en la Gran Área Metropolitana (GAM), Costa Rica 

      Camacho Calvo, Ana Marlen; Arauz Vásquez, Karen Lorena; Barboza Vargas, Natalia; Martínez Higuera, Héctor A.; Arias Reverón, Julio Miguel (2015)
      Para caracterizar la población de productores que distribuyen hortalizas orgánicas en la Gran Área Metropolitana (GAM) de Costa Rica, se aplicó una encuesta semi-estructurada a 30 de ellos, ubicados en distintos puntos de ...
    • Cytological Identification of Chromosomal Rearrangements in Doritaenopsis and Phalaenopsis 

      Bolaños Villegas, Pablo Alberto; Chen, Fure-Chyi (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 ...
    • Meiotic Chromosome Behavior and Capsule Setting in Doritaenopsis Hybrids 

      Bolaños Villegas, Pablo Alberto; Chin, Shih-Wen; Chen, Fure-Chyi (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 ...
    • Pollen development: a play with many actors 

      Bolaños Villegas, Pablo Alberto; Jane, Wann-Neng; Jauh, Guang-Yuh (Current Topics in Plant Biology 11: 89-102. 2010, 2010-09-01)
      Seeds are a major resource of food supply around the world and their production depends on successful double fertilization during plant sexual reproduction. In higher plants, fertilization of female gametophytes involves ...
    • Pollen Meiotic Behavior in Relation to Phalaenopsis Breeding 

      Hsu, Shih-Chieh; Cheng, T.C.; Bolaños Villegas, Pablo Alberto; Chin, Shih-Wen; Chen, Fure-Chyi (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 ...
    • Protocol for the preparation of Arabiopsis meiotic chromosome spreads and fluorescent in situ hybridization 

      Bolaños Villegas, Pablo Alberto; Yang, Xiaohui; Makaroff, Christopher A.; Jauh, Guang-Yuh (Bio-protocol 4(7), e1102, 2014, 2014-04-05)
      This protocol is a more detailed version of previous protocols (Yang et al., 2011; Bolaños-Villegas et al., 2013) developed for the examination of meiotic chromosome spreads. Meiotic chromosome spreads are useful to determine ...
    • Rise of the clones: apomixis in plant breeding 

      Bolaños Villegas, Pablo Alberto; Thangasamy, Saminathan; Jauh, Guang-Yuh (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 ...
