Researchers have a new understanding of the genetic makeup of a fungus that causes the disease Wheat Stripe Rust, one of the most destructive wheat diseases globally costing $1 billion annually.
Research that could transform global rice production by increasing yields from the world’s number one food crop has been boosted by five more years of funding.
Some clever detective work by an international team of scientists has uncovered how a deadly fungus - a stem rust called Ug99 - came about through some unusual breeding habits. The discovery will help protect wheat crops around the world from devastating fungal diseases.
Researchers at The Australian National University (ANU) have shown how Australian wheat crops would cope if a destructive disease that’s yet to hit our shores ever made it into the country.
Plant biotechnology predominantly relies on a restricted set of genetic parts with limited capability to customize spatiotemporal and conditional expression patterns.
As sessile organisms, plants have evolved a multitude of mechanisms to acclimate to their environment enabling the plant to optimise development and reproduction, and fight off or resist both biotic and abiotic stresses they may encounter through their life cycle.
C4 photosynthesis, a carbon concentrating mechanism, evolved as an adaptation to improve photosynthetic CO2 assimilation in terrestrial plants under conditions of low CO2, increased temperatures and varying rainfall patterns.
Cell-to-cell communication is essential for the co-ordination of responses in all multicellular organisms. One mechanism plants employ as defence against pathogens is restriction of cell-to-cell communication by plasmodesmata closure during infection.
