Genetic diversity in Musa acuminata Colla and Musa balbisiana Colla and some of their natural hybrids using AFLP markers
Publicado 2002“…Banksii (F.Muell) Simmonds] clustered very closely with ‘Gros Michel’and ‘Km 5’, indicating that more than one M. acuminate subspecies may be involved in the origin of triploid AAA bananas. ‘Calcutta 4’ (ssp. burmannicoidesDeLanghe & Devreux) and ‘Long Tavoy’ (ssp. burmannica) were closely related and could be together in the same subspecies. …”

Unravelling genomic drivers of speciation in musa through genome assemblies of wild banana ancestors
Publicado 2025“…These assemblies provide key resources for banana genetics and for improving cultivar assemblies, including that of the emblematic triploid Cavendish. Comparative and phylogenetic analyses reveal an ongoing speciation process within Musa , characterised by large chromosome rearrangements and centromere differentiation through the integration of different types of repeated sequences, including rDNA tandem repeats. …”

Advancements and strategies of genetic improvement in cassava (Manihot esculenta Crantz): from conventional to genomic approaches
Publicado 2025“…Finally, we put forward the perspective of developing genomic selection breeding model and super-hybrids of cassava through building inbreeding population and emphasize the generation of triploid cassavas, as well as using gene editing technology allowing cassava to be a tropical model plant to serve for basic biological research and molecular breeding.…”

Functional analysis of pollen tube growth dynamics in banana (Musa spp.)
Publicado 2025“…Pollen tube growth dynamics were assessed in several controlled crosses using both wild diploid and cultivated diploid/triploid varieties. Pre-anthesis pollination as well as the timing of pollination during the day (morning vs. evening), were also tested to evaluate their influence on pollen tube growth. …”

Combined effects of inflorescence developmental age and environmental conditions during microgametogenesis on pollen viability, germination and size in Musa acuminata ssp
Publicado 2025“…Methods In this study pollen viability, germination capacity, and diameter, were closely monitored throughout the entire male flowering phase of Musa acuminata wild diploids, and diploid and triploid cultivars. Additionally, environmental parameters, including temperature, light radiation, and humidity, were monitored up to 40 days before anthesis to determine their influence on microgametogenesis. …”

Differential root transcriptomics in a polyploid non-model crop: the importance of respiration during osmotic stress
Publicado 2016“…To explore the transcriptomic global response to osmotic stress in roots, 18 mRNA-seq libraries were generated from three triploid banana genotypes grown under mild osmotic stress (5% PEG) and control conditions. …”

Genomic breeding approaches for East African bananas
Publicado 2016“…The polyploidy nature of banana is a limiting factor in the implementation of strategies such as marker assisted selection (MAS) or genome wide association mapping (GWAS). The triploid nature of cultivated varieties complicates conventional breeding strategies and improved varieties can take up to 20 years before they can be released to the public, which necessitates the use of efficient molecular tools to more rapidly respond to abiotic and biotic stresses and to address the needs of growers and consumers. …”
