Selection for Phytophthora Root Rot Resistance in Chickpea Crosses Affects Yield Potential of Chickpea × Cicer echinospermum Backcross Derivatives Open
Phytophthora root rot (PRR) of chickpea (Cicer arietinum) caused by Phytophthora medicaginis is an important disease. Partial resistance to PRR is sourced from Cicer echinospermum. In this study, we evaluated if lines with low levels of PR…

Inhibition of auxin biosynthesis in early rice grains leads to extensive post-fertilisation grain abortion Open
In spite of its abundant presence in rice grains, auxin functions during grain development are not understood well. Absence of grain-specific auxin biosynthesis mutants in rice further limits our understanding in this respect. Here, we rep…

Inoculum production of Phytophthora medicaginis can be used to screen for partial resistance in chickpea genotypes Open
Phytophthora root rot caused by Phytophthora medicaginis is an important disease of chickpeas ( Cicer arietinum ) in Australia with limited management options, increasing reliance on breeding for improved levels of genetic resistance. Resi…

“Killer Joules”: spores of Bipolaris sorokiniana and fusarium species are susceptible to microwave radiation Open
Cereal production in Australia is severely impacted by diseases such as Fusarium crown rot (caused predominantly by Fusarium pseudograminearum ) and common root rot (caused by Bipolaris sorokiniana ). These diseases are particularly diffic…

Stubble trouble! Moisture, pathogen fitness and cereal type drive colonisation of cereal stubble by three fungal pathogens Open
Stubble-borne cereal diseases are a major constraint to production in Australia, with associated costs rising as a result of increased adoption of conservation agriculture systems. The fungal pathogens that cause these diseases can saprotr…

Aggressiveness of <i>Phytophthora medicaginis</i> on chickpea: Phenotyping method determines isolate ranking and host genotype‐by‐isolate interactions Open
Phytophthora medicaginis causing Phytophthora root rot of chickpea ( Cicer arietinum ) is an important disease, with genetic resistance using C . arietinum × Cicer echinospermum crosses as the main disease management strategy. We evaluated…

Localised expression of<i>OsIAA29</i>suggests a key role for auxin in regulating development of the dorsal aleurone of early rice grains Open
Endosperm of rice and other cereals accumulates high concentrations of the predominant in planta auxin, indole-3-acetic acid (IAA) during early grain development. However, IAA signalling and function during endosperm development are poorly…

Expression of<i>TaTAR2.3-1B</i>,<i>TaYUC9-1</i>and<i>TaYUC10</i>correlates with auxin and starch content of developing wheat grains Open
The role of auxin in developing grains of wheat ( Triticum aestivum ) is contentious with contradictory reports indicating either positive or negative effects of IAA (indole-3-acetic acid) on grain size. In addition, the contributions to t…

A Comparative Study of Field Nematode Communities over a Decade of Cotton Production in Australia Open
Soil nematode populations have the potential to indicate ecosystem disturbances. In response to questions about nematode interactions with soilborne diseases and whether genetically modified cotton altered nematode populations, several fie…
