TL;DR: Dopamine had greater antioxidative potency than glutathione, food additives such as butylated hydroxyanisole and hydroxytoluene, flavone luteolin, flavonol quercetin, and catechin, and similar potency to the strongest antioxidants gallocatechin gallate and ascorbic acid.
Abstract: A strong water-soluble antioxidant was identified in the popular commercial banana Musa cavendishii. It is dopamine, one of the catecholamines. For suppressing the oxygen uptake of linoleic acid in an emulsion and scavenging a diphenylpicrylhydrazyl radical, dopamine had greater antioxidative potency than glutathione, food additives such as butylated hydroxyanisole and hydroxytoluene, flavone luteolin, flavonol quercetin, and catechin, and similar potency to the strongest antioxidants gallocatechin gallate and ascorbic acid. Banana contained dopamine at high levels in both the peel and pulp. Dopamine levels ranged from 80-560 mg per 100 g in peel and 2.5-10 mg in pulp, even in ripened bananas ready to eat. Banana is thus one of the antioxidative foods.

TL;DR: In vitro propagation produces banana clones that arc very diverse and may be an ideal procedure for horticulturists to select banana clones producing fruit with different taste and might be possible for plant pathologists to select clones resistant to other important diseases.
Abstract: In vitro propagation produces banana clones that arc very diverse. For 'Giant Cavendish', in addition to resistance to Fusarium wilt, the tissue culture method also generated clones with increased resistance to strong wind, heavier fruit bunches, and sweeter fruit. Therefore, it may be an ideal procedure for horticulturists to select banana clones producing fruit with different taste and might be possible for plant pathologists to select clones resistant to other important diseases. The possibility of applying this technique to the improvement of other crops remains to be exploited. Although 40,000 'Cavendish' plants grown from suckers did not show any visible difference in morphology, about 3 percent of 'Cavendish' plantlets derived from tissue culture were variants. Relatively little is known about the cause of genetic instability induced by the in vitro vegetative propagation. Rapid multiplication and development of cells resulting from mediation of regulators in the tissue culture medium may increase the chance of variation. The mechanism by which the somaclones of 'Giant Cavendish' are resistant to Fusarium wilt is unknown. Since the parental 'Giant Cavendish' is very susceptible to Fusarium wilt, the appearance of resistant somaclones may result from activation of silent resistant genes. However, the creation of resistance genes through mutation as the origin of the resistant phenotype cannot be ruled out. DNA technology will be useful in deciphering the true nature of wilt resistance in the future.

TL;DR: Banana pseudo stem has been known as a potential cellulose source, though usually discarded as agricultural waste in Indonesia as discussed by the authors, and a method to utilize cavendish banana pseudo stem for preparing sodium carboxymethylcellulose (CMC) and its characteristics.

TL;DR: Plants were regenerated, under selection with kanamycin, that were co-transformed with nptII and either the uidA or BBTV genes.
Abstract: An effective method has been developed for the stable transformation and regeneration of Cavendish banana (Musa spp. AAA group) cv 'Grand Nain' by microprojectile bombardment. Embryogenic cell suspensions were initiated using immature male flowers as the explant. Cells were co-bombarded with the neomycin phosphotransferase (nptII) selectable marker gene under the control of a banana bunchy top virus (BBTV) promoter or the CaMV 35S promoter, and either the β-glucuronidase (uidA) reporter gene or BBTV genes under the control of the maize polyubiquitin promoter. Plants were regenerated, under selection with kanamycin, that were co-transformed with nptII and either the uidA or BBTV genes. Molecular characterisation of transformants demonstrated that the transgenes had been stably integrated into the banana genome.

TL;DR: In this article, the authors analyzed genomic variation of the translation elongation factor 1α (TEF-1α) and the intergenic spacer region (IGS) of the nuclear ribosomal operon of Fusarium oxysporum f. sp. cubense (Foc) isolates, from different banana production areas, representing strains within the known races, comprising 20 vegetative compatibility groups (VCG).
Abstract: This study analysed genomic variation of the translation elongation factor 1α (TEF-1α) and the intergenic spacer region (IGS) of the nuclear ribosomal operon of Fusarium oxysporum f. sp. cubense (Foc) isolates, from different banana production areas, representing strains within the known races, comprising 20 vegetative compatibility groups (VCG). Based on two single nucleotide polymorphisms present in the IGS region, a PCR-based diagnostic tool was developed to specifically detect isolates from VCG 01213, also called tropical race 4 (TR4), which is currently a major concern in global banana production. Validation involved TR4 isolates, as well as Foc isolates from 19 other VCGs, other fungal plant pathogens and DNA samples from infected tissues of the Cavendish banana cultivar Grand Naine (AAA). Subsequently, a multiplex PCR was developed for fungal or plant samples that also discriminated Musa acuminata and M. balbisiana genotypes. It was concluded that this diagnostic procedure is currently the best option for the rapid and reliable detection and monitoring of TR4 to support eradication and quarantine strategies.
