Abstract:
... Banana and plantain (Musa spp.) are seed-sterile vegetatively propagated crops, which originated as intraspecific hybrids of Musa acuminate and interspecific hybrids between M. acuminate and Musa balbisiana. The rich genetic diversity of this crop is, however, endangered by diseases, adverse environmental conditions and changing farming practices. To set up an efficient and effective strategy for ...

Abstract:
... Black leaf streak (BLS) is a devastating disease for many traditional banana cultivars. In Brazil, resistant cultivars are being studied but consumers' preference needs to be taken into account for adoption to be successful. In this work, the acceptability of six BLS-resistant hybrids, 'Vitoria', 'Maravilha', 'PA 4244', 'FHIA-18', 'Tropical' (all AAAB group) and 'Bucanero' (AAAA), was assessed in ...

Abstract:
... Sigatoka leaf spot, caused by the fungus Mycosphaerella musicola, significantly reduces leaf area and causes premature fruit ripening in banana. It is thus fundamentally important to develop genotypes resistant to fungal pathogens via crop improvement. In this context, transcriptional activity of NBS-LRR Resistance Gene Analogs (RGAs) was compared from whole plant leaf material from Musa acuminate ...

Abstract:
... During fruit development, banana accumulates starch, which is then degraded during ripening. This degradation provides precursors for sucrose and volatile compounds, responsible for sweetness and the characteristic aroma of the fruit. Starch metabolism may be influenced by the phytosanitary status of the plant. Black leaf streak disease (BLSD), caused by the pathogenic fungus Mycosphaerella fijien ...

Abstract:
... In eastern Africa, banana - a key staple for 20 million people - suffers increasingly from pests and diseases. Population pressure has reduced farmers' ability to access mulch and manure and to rotate crops and fallow fields. This, coupled with the nutrient offtake via increased banana sales, has resulted in declining soil fertility. Few farmers use pesticides and mineral fertilizers due to their ...

Abstract:
... Past phylogenetic studies pointed to some Mlali clones (AAcv) as the 2N gamete donor parents of 'Cavendish' (AAA) and 'Gros Michel' (AAA) cultivars, thus revealing their significance to Musa breeding. Nevertheless, cultivated bananas are usually highly sterile at diploid and triploid level, which seriously hampers the production of new hybrids. Therefore, it is necessary to investigate the floral ...
