“…The genetics of the genus Glomerella were first studied by Edgerton (1912Edgerton ( , 1914. Cytogenetic, morphogenetic and morphological studies have also been conducted with G. cingulata (Hüttig, 1935;Lucas, 1946;Wheeler et al, 1948;McGahen & Wheeler, 1951;Uecker, 1994), but isolates from common bean were not included until recently (Roca et al, 2000). The sexual form of C. lindemuthianum was not reported until 1970 when the formation of fertile perithecia through crosses in culture medium was observed (Kimati & Galli, 1970).…”

Cytogenetic and morphological studies were conducted with Colletotrichum lindemuthianum (Glomerella cingulata f. sp. phaseoli), the pathogen responsible for anthracnose of common bean (Phaseolus vulgaris). In this species, there is some evidence of genomic variation but it is unknown whether the process occurs in a manner similar to other fungal genetic models. Six isolates from bean plants were used and sexual reproduction was observed in vitro. Meiosis and ascospore formation were investigated by cytogenetical approaches and light microscopy. To study the nucleus and chromosome numbers, a mixture of carmine and orcein propionic dyes was used. Nucleus divisions as well as ascospore maturation were asynchronous. Meiosis was observed in three isolates. In the asexual form, chromosomal polymorphism in conidia was also observed microscopically and the mitosis process was described.

“…De las cepas obtenidas se identificó a Colletotrichum gloeosporioides (fase anamórfica, asexual o imperfecta) y Glomerella cingulata (fase teleomórfica, sexual o perfecta). Se observaron hifas septadas (Roca et al, 2000), los conidios son variables en tamaño, de forma cilíndrica y obtusos en el ápice, con medidas de 9 a 24 μm de largo y 3 a 4.5 μm de ancho (Cano et al, 2004). El micelio se caracterizó por ser blanco y algodonoso, con masas conoidales salmón y negras (Figura 1).…”
