Upstream Biotechnology – we’re a team of plant technologist pioneers, deconvoluting the complex regulatory networks controlling plant gene expression into simple, powerful solutions to improve grower profitability and build resilience in the food value chain.
Corn production is threatened by a variety of fungal diseases each harvest. Current disease management relies on the heavy use of broad-spectrum fungicides. Pathogens have begun evolving resistance to these fungicides, reducing their efficacy. Switchblade is being developed in corn to deliver a durable broad-spectrum resistance alternative for growers.
Huanglongbing (HLB) or Citrus Greening is the most devastating citrus diseases worldwide. Infection results in stunting of tree growth, loss of fruit quality and ultimately death. There are no current fungicide or genetic resistance traits to effectively control the spread of HLB. This bacterial disease has crippled Florida citrus production and is currently threatening California production. Switchblade is being developed in citrus to provide viable genetic solution to this crisis.
Tomatoes are grown throughout the world as an essential staple of many cuisines. SwitchBlade is being developed in this crop to provided broad-spectrum resistance to the over 200 different diseases tomato is vulnerable to, including a variety of fungi, bacteria, nematodes, and virus.
Soy rust is a devastating disease resulting in over a billion dollars in lost production each year. On the left, you see plants without effective resistance. On the right, the effective resistance of Switchblade soy plant.
