Scientists have isolated the very first rust pathogen gene that wheat plants detect...

Mr Jiapeng Chen, a PhD candidate from the University of Sydney who initiated the work by sequencing and analysing the genome of a virulent rust isolate, said this was the first important step in addressing the diagnostic challenges posed by ever-changing fungi, which result in new rust pathogen strains.

Professor Park explained: "It's like an ongoing arms race - we've got to keep one step ahead of this changing pathogen.

"The last major epidemic of wheat stem rust in Australia alone, in 1973, caused $AU300 million in damage - imagine what that would be today."

Co-corresponding author, Dr Peter Dodds from the Commonweatlh Scientific Industrial Research Organisation, said demand for wheat in the developing world was expected to jump 60 percent by 2050 and in economic terms alone the ramifications were huge.

"Now that we've identified how stem rust strains are able to overcome Sr50 resistance - by mutation of a gene we've identified called AvrSr50 - this information can be used to help prioritise resistance genes for deployment.

Can they tell us why Rust never sleeps?

Could it be possible, that the rust protects the wheat from another threat?

Oh...stem rust. That’s bad. Well, might the gene itself protect the wheat from something else?

***Can they tell us why Rust never sleeps?***

Reminds me of a T-shirt sign I saw years ago in the late 1970s.

“Step outside, and on a cold clear night you can hear a CHEVY RUST!”

Actually, I’ve found that apple cider vinegar
works pretty well...on the feet.

Sounds like the last season of The Last Ship.

“demand for wheat in the developing world was expected to jump 60 percent by 2050”

Yeah, just like we ran out of crude oil in 1980.

How come it isn’t illegal to issue Malthusian nonsense predictions?
