Australia has strong
routed agricultural base. We
have targeted wheat and barley, because they are the most basic crops and have
great economic importance ti Australia and world. The total gross value of
agricultural production in Australia for 2015-16 was $56b. Crops contributed
$27.3b to the total value of agriculture in Australia.

Value of agricultural
commodities according to GRDC published in 2017.

$m 6170.1- Wheat change in value is
12.1% reduced from 2014-15

$m 2276.6- Barley change in value is
3.8% reduction from 2014-15

 

22,275,000 tons of wheat was produced on
11,282,000 hectares of land- June 14-15.

 

Major fungal infections in wheat are
rust, crown rot and head blight and barley are crown rot, leaf rust and powdery
mildew. Reason for targeting fusarium is it has a very broad spectrum of
infection and in a biosecurity threat.

 

Fusarium
graminerum causes- head blight Hosts are Wheat (Triticum
aestivum), Durum Wheat (Triticum durum), Barley (Hordeum vulgare)
and Oat (Avena sativa). F. graminearum parasitizes
roots, stems, leaves, and reproductive tissues of many species of cereals and
grasses.

 

Fusarium pseudograminerum causes- Crown rot on bread (Triticum aestivum L.)
and durum (Triticum turgidum L. spp. durum (Dest.)) wheat and barley (Hordeum
vulgare L.). Oats (Avena sativa L.) can be infected but show little or no
disease symptoms. In addition, the pathogen has been isolated from various
other grass genera such as, Phalaris, Agropyron and Bromus that may occur as
common weeds.

 

Fusarium culmorum causes- foot and root rot on
mainly cereals, such as wheat, barley, oats, rye, corn, sorghum and various
grasses. In addition, it has been isolated from sugar beet, flax, carnation,
bean, pea, asparagus, red clover, hop, leeks, Norway spruce, strawberry and
potato tuber. Fusarium culmorum has also been associated with dermatitis
on marram grass planters in the Netherlands, although its role as a causal
agent of skin lesions appears questionable. It is also isolated as a symbiont
able to confer resistance to abiotic stress, and has been proposed as a
potential biocontrol agent to control the aquatic weed Hydrilla spp.

 

We have
isolated fusarium from crown samples of wheat and cultured them on Potato
Dextrose Agar, currently confirming species of the isolated fungus by gene
specific primers Polymerase Chain Reaction. After confirming the isolates we
will perform cell SELEX with the help of SELEX library which is
