QLD_gov_au 04/08/20 Taiwan and Queensland trial disease-busting bananas (TR4) Article published - 4 August 2020 Scientists in Taiwan and Queensland are collaborating to create banana varieties that can better resist Panama TR4 – a disease that is threatening the banana industry worldwide.
The latest step in the project saw seedlings from 6 varieties of TR4-resistant banana varieties arrive in Brisbane from the Taiwan Banana Research Institute (TBRI) on 15 July. After a quarantine period, the plants will be grown in disease and agronomic screening trials managed by the Department of Agriculture and Fisheries (DAF) at 3 locations across Australia. DAF Team Leader for Banana Production Systems Stewart Lindsay said the research process was a long road but very worthwhile. ‘The small clonal plantlets we received from the TBRI will need to be quarantined for 2 years before we can safely begin trials, so it’s not a quick process,’ he said. Mr Lindsay said global collaboration was critical in fighting the disease. FRONT. PLANT SCI. 13/01/21 Using Genetic Engineering Techniques to Develop Banana Cultivars With Fusarium Wilt Resistance and Ideal Plant Architecture. Introduction Bananas (Musa ssp.), which originated in Southeast Asia, are widely cultivated throughout the tropics and sub-tropics, where they represent part of the staple diet and are a vital source of nutrition for over 500 million people (Wang et al., 2019).
Due to their widespread popularity, bananas have the largest market share of any fruit worldwide (Langhe et al., 2008). Because bananas are nutritious and starchy, they are considered the fourth most important food crop after rice, wheat, and maize for the alleviation of human starvation in Africa by the United Nations Food and Agriculture Organization (Song et al., 2018). In 2019, worldwide banana production was over 113 million tons; the two largest producers of bananas are India (36.7%) and China (13.8%) (Tzean et al., 2019). Banana plantations are seriously threatened by various biotic and abiotic stresses, such as diseases, drought, and low temperatures (Michael and Abdou, 2011; Tripathi et al., 2015). SIFTED_EU 02/07/20 The race to save the banana - Tropic Biosciences is using gene editing to create a banana resistant to the deadly Panama disease that threatens to wipe out the fruit worldwide.
It is a stealthy disease that countries have been trying struggling to stall with quarantines.
As it spreads inexorably around the world, it’s proving devastating to national economies. No, this is not Covid-19, but it’s banana equivalent: TR4, also known as Panama disease, which is threatening to wipe out our favourite yellow-skinned fruit. Supermarket shelves may still be stocked chock-full of bananas, but the industry is growing increasingly alarmed. The fungal disease, which causes banana plants to wilt and die has already devastated farms across Taiwan, the Philippine and Australia. Once in the soil, it can take 50 years to eradicate. “We really can’t do this fast enough. The race is on to find a cure for Panama disease or to breed a banana that is resistant to it. “We really can’t do this fast enough.

NATURE 24/09/19 CRISPR might be the banana’s only hope against a deadly fungus.
The race to engineer the next-generation banana is on.
The Colombian government confirmed last month that a banana-killing fungus has invaded the Americas — the source of much of the world’s banana supply. The invasion has given new urgency to efforts to create fruit that can withstand the scourge. THETIMES_CO_UK 16/08/19 Hi-tech banana laboratory leads fight against deadly fungus Panama Disease. That the catastrophe was anticipated did not make its arrival any the less upsetting.
“We knew this day would come,” said Gilad Gershon, speaking from Britain’s most high-tech banana laboratory. “But the fact it has really happened is a shock.” Earlier this week, Colombia confirmed that its bananas were infected with a killer fungus. After ravaging plantations across Asia, Panama Disease has officially made landfall in the New World. We know what will happen next.

Plant transformation and characterization Binary vectors containing either the C. elegans gene Ced9 under the control of a maize Ubi-P and a cauliflower mosaic virus 35s terminator (35S-T)8 or the M. acuminata ssp. malaccensis RGA2 under the control of the Agrobacterium tumefaciens Nos-P and terminator sequences17 were used in this study M. acuminata Cavendish cv.
GN (AAA subgroup) embryogenic cell suspensions were prepared from immature male flowers and transformed using the centrifugation assisted A. tumefaciens-mediated method18. Following selection, plants derived from single embryos were regenerated and were screened for the presence of the respective transgene by PCR using specific primers. A total of six RGA2 and nine Ced9 lines were generated, and up to 10 replicates of each transgenic line was multiplied in tissue culture for field analysis. Field trial design.

FRESH FRUIT PORTAL 23/12/16 Australia approves field trials for Panama disease-resistant GM banana. December 23 , 2016 Australia's Gene Technology Regulator has authorized the 'limited and controlled' release of a banana genetically modified to be resistant for resistance to Fusarium wilt, also known as Panama disease.
The entity said it had invited submissions on the Risk Assessment and Risk Management Plan (RARMP) on Oct. 13 for the application from Queensland University of Technology, and has now decided the researchers can move to field trials. "The release is authorised to take place at one site of up to 6 hectares in Litchfield Municipality, Northern Territory, for a period of 5 years," the Gene Technology Regulator said.
