This study was conducted at the tissue culture laboratory in Pakistan. Suckers obtained from the banana cv. Grand Nain to explore the effects of different concentrations of BAP and IAA. After inoculation with Murashige and Skoog (MS) medium supplemented with different concentrations of 6-Benzylaminopurine (BAP) and the Indole-3- acetic acid (IAA) the suckers first turn into the brown after 5-10 days then turned into a green mass-like structure after 30 days. From this mass-like structure shoots and roots were developed. Among the different concentrations, BAP 7.5 mg/l and IAA 0.5 mg/l showed the highest number of shoots 0.75, 2.75 and 6.25 per explant and shows the highest shoot lengths which 1.03 cm, 2.45 cm and 3.40 cm respectively. IAA is essential for only roots proliferation. The roots of different lengths were produced when the concentration of IAA 0.5 mg/l was used and 2.93 cm, 4.63 cm and 5.88 cm roots length produced at 15, 30 and 45 days after occultation respectively. Then these plants were transferred to the greenhouse for hardening acclimatization with the environment, the hardening process took place, and the established plantlets are ready for planting.

“…The in vitro co-culturing of banana plants with Pseudomonas fluorescens Pf1, Bacillus subtilis EPB 10 and EPB 56 provided a successful control of FWB in the field, combined with increased leaf nutrient status, vegetative growth, bunch yield and fruit quality (Kavino et al, 2016). In two other field trials, the endophyte and rhizobacteria strain led to a FWB control of 78% and a significant higher bunch weight (Kavino and Manoranjitham, 2018). Furthermore, this strategy was also proved to be successful when inoculating banana tissue culture plantlets with a mixture of naturally-occurring uncultivated endophytes from healthy banana plants of a commercial plantation (Lian et al, 2009).…”

“…Banana tissue culturing is widely used as a source of pathogen-free planting material. Since banana plantlets produced by these micropropagation schemes are more susceptible to diseases due to the absence of the natural-associated microbiota, the reintroduction of endophytic and rhizospheric microorganisms to protect the plant against subsequent challenges by Foc is an approach that yielded promising results (Kavino et al, 2014, 2016; Kavino and Manoranjitham, 2018). The in vitro co-culturing of banana plants with Pseudomonas fluorescens Pf1, Bacillus subtilis EPB 10 and EPB 56 provided a successful control of FWB in the field, combined with increased leaf nutrient status, vegetative growth, bunch yield and fruit quality (Kavino et al, 2016).…”

In the last century, the banana crop and industry experienced dramatic losses due to an epidemic of Fusarium wilt of banana (FWB), caused by Fusarium oxysporum f.sp. cubense ( Foc ) race 1. An even more dramatic menace is now feared due to the spread of Foc tropical race 4. Plant genetic resistance is generally considered as the most plausible strategy for controlling effectively such a devastating disease, as occurred for the first round of FWB epidemic. Nevertheless, with at least 182 articles published since 1970, biological control represents a large body of knowledge on FWB. Remarkably, many studies deal with biological control agents (BCAs) that reached the field-testing stage and even refer to high effectiveness. Some selected BCAs have been repeatedly assayed in independent trials, suggesting their promising value. Overall under field conditions, FWB has been controlled up to 79% by using Pseudomonas spp. strains, and up to 70% by several endophytes and Trichoderma spp. strains. Lower biocontrol efficacy (42–55%) has been obtained with arbuscular mycorrhizal fungi, Bacillus spp., and non-pathogenic Fusarium strains. Studies on Streptomyces spp. have been mostly limited to in vitro conditions so far, with very few pot-experiments, and none conducted in the field. The BCAs have been applied with diverse procedures (e.g., spore suspension, organic amendments, bioformulations, etc.) and at different stages of plant development (i.e., in vitro , nursery, at transplanting, post-transplanting), but there has been no evidence for a protocol better than another. Nonetheless, new bioformulation technologies (e.g., nanotechnology, formulation of microbial consortia and/or their metabolites, etc.) and tailor-made consortia of microbial strains should be encouraged. In conclusion, the literature offers many examples of promising BCAs, suggesting that biocontrol can greatly contribute to limit the damage caused by FWB. More efforts should be done to further validate the currently available outcomes, to deepen the knowledge on the most valuable BCAs, and to improve their efficacy by setting up effective formulations, application protocols, and integrated strategies.

“…Positive interactions are predicted to enhance a community's diversity and productivity but decrease its stability (6,25,26). Therefore, a better understanding of these interactions would enhance our ability to manipulate and manage communities, with widespread applicability in environmental conservation (27), crop health (28), and human health (29). Nevertheless, the data required for quantifying the distribution of interactions across environments is still lacking due to methodological limitations that frustrate comprehensive sampling of interactions under many conditions (30).…”

Interspecies interactions shape the structure and function of microbial communities. In particular, positive, growth-promoting interactions can significantly affect the diversity and productivity of natural and engineered communities. However, the prevalence of positive interactions and the conditions in which they occur are not well understood. To address this knowledge gap, we used kChip, an ultra-high throughput coculture platform, to measure 180,408 interactions among 20 soil bacteria across 40 carbon environments. We find that positive interactions, often described to be rare, occur commonly, primarily as parasitisms between strains that differ in their carbon consumption profiles. Notably, non-growing strains are almost always promoted by strongly growing strains (85%), suggesting a simple positive interaction-mediated approach for cultivation, microbiome engineering, and microbial consortium design.One Sentence Summary: Experimental measurement of >150,000 bacterial cocultures reveals that growth-promoting interactions occur commonly and depend on differences in nutrient consumption preferences.
