Normalistas S. Domingo Ruvalcaba-Ruiz: se. This article has been cited by other articles in PMC. Abstract Background Agave tequilana Weber var. Despite the economic, genetic, and ornamental value of the plant, it has not been subjected to detailed cytogenetic research, which could lead to a better understanding of its reproduction for future genetic improvement.
The objective of this work was to study the meiotic behavior in pollen mother cells and its implications on the pollen viability in Agave tequilana Weber var. In which 5. In anaphase II some cells showed bridges and fragments too. Aberrant A-I cells had many shrunken or empty pollen grains Conclusion The observed meiotic irregularities suggest that structural chromosome aberrations have occurred, such as heterozygous inversions, sister chromatid exchanges, deletions and duplications which in turn are reflected in a low pollen viability.
Background The genus Agave, is distributed in the tropical and subtropical areas of the world and represents a large group of succulent plants, with taxa from species, and its center of origin is probably limited to Mexico [ 1 ]. The subgenus Agave and particularly the sections Rigidae and Sisalanae, are cultivated because of their commercial importance for diverse purposes: a alcoholic beverages such as tequila and mezcal; b natural long and hard fibers; and c steroidal compounds and medicinal principles [ 2 - 4 ].
The genus Agave is a semelparus perennial that produces flowers only once towards the end of its life cycle 6—8 years for A. This genus has been the object of cytological investigations only after , since then, chromosome counts have been made on a large number of species. Cave [ 8 ] reported regular meiosis in five diploid, two tetraploid and one hexaploid species, and irregular meiosis in two polyploids, where bridges and fragments were observed at anaphase I. Brandham [ 9 ] carried out a cytological investigation in Agave stricta, for which he described a meiotic behavior heterozygous for a paracentric inversion, that produced a number of aberrations: one bridge and one fragment, two loops and one fragment, two bridges and two fragments, and two loops with two fragments at anaphase I.
