1100 – 1300 Stay Connected with Plant Pathology Education

There are concerns that the skills in the discipline of plant pathology are declining through the disappearance of educational and training opportunities. APPS has periodically carried out reviews of teaching, training and capacity to meet the needs of plant pathology as a discipline throughout the region with systematic reviews done in 2006 and 2012. We will be running a further survey to assess changes over the last 9 years with the purpose of this workshop being to discuss the current status of and gaps in current training opportunities across Australasia, to hear from industry about their requirements, and to consider student needs.

The goal of the workshop is for the Society membership to develop a position document for lobbying government, education institutions, and funding bodies, and desirably suggest solutions to improve plant pathology education in the immediate and long term. This document will also be published in the Society’s journal Australasian Plant Pathology.

This is an exciting opportunity for everyone to help ensure the future of our discipline, so please come along, share your views and be included in this important work of the Society.

This workshop will be facilitated by the Society’s President: Dr Robin MacDiarmid, Plant & Food Research, New Zealand and Vice President: Dr Colleen Higgins, Auckland University of Technology.

Estimating the impacts of plant diseases and assessing pathways for research to deliver sustainable disease management strategies

Plant pathogens are part of plant ecosystems. When they affect crops, losses in the range of 10-40% are estimated, depending on the crop and region of the world. A range of approaches exist to estimate crop losses resulting from disease epidemics, to identify and to quantify their underlying processes. There are approaches, too, to conduct scenario analyses to inform stakeholders. Informed decisions can then be made, be it for setting priorities in research and breeding programs, or for policies related to disease management. Bottlenecks and avenues are discussed.

Dr Laetitia Willocquet
Laetitia Willocquet is a plant disease epidemiologist working at INRAE, France. She has worked in French and International Research Institutes, on a number of crops: rice diseases in tropical Asia; wheat, grapevine, strawberry, pea, and sunflower diseases in France; and bean and coffee diseases in Central America. She has worked on the analysis of the spatio-temporal development of epidemics, on the impact of plant diseases on crop yield, and on the use of quantitative resistance to manage plant diseases. These analyses involved experimental, statistical, and modelling approaches. Her current interest mainly focuses on wheat diseases, their variation over years and regions, and their impact on wheat production.

Dirt-boot pathology in an international setting: experiences to learn from and enjoy

The paper addresses disease issues related to Rob’s Australian and overseas sugarcane experience. Difficulties associated with working locally and overseas will be discussed and the challenges facing those who use both traditional and advanced technologies. Disease epidemics have been part and parcel of the Australian sugarcane industry; research to minimise the scale of these events and their economic effects, will be outlined. Situations as diverse as developing assays based on household bleach, to applying DNA technology to sugarcane juice, to chartering flights to remote parts of PNG are the type of activities undertaken by a ‘dirt-boot’ sugarcane pathologist. Running into a pack of barking dogs in Thailand is a different story.

Dr Rob (Robert) Magarey
Rob has worked with the Australian sugarcane industry for over 40 years, researching many diseases; the development of appropriate management strategies has been the ultimate goal. His initial emphasis was on soil-borne diseases, including one caused by a previously undescribed Oomycete, Pachymetra chaunorhiza – a pathogen unique to Queensland cane-fields. He has since worked on diseases of bacterial, fungal, protozoan, and phytoplasma origin. Research projects have taken him on quarantine surveys around the northern Australian, Torres Strait and PNG coastlines, to identify potential pest and disease threats to Australia. He has led 8 international research projects involving PNG and Indonesian scientists, with a focus on the aetiology and management of pests and diseases. He has close links with scientists around the world and is a past-President of APPS.

From the field to the lab and back: Translational strategies to improve disease management in vegetable crops

Pseudoperonospora cubensis, an obligate oomycete pathogen, causes cucurbit downy mildew (CDM) on a broad range of host plants including cucumber, cantaloupe, watermelon, pumpkin, and squash. In 2004, CDM re-emerged in the United States (US) by overcoming host resistance in cucumber and fungicides used for disease control in other cucurbits. Population genetics analysis revealed two host-adapted clades in P. cubensis with clade 1 preferentially infecting squash, pumpkin, and watermelon, and clade 2 infecting cucumber and cantaloupe. Using Next Generation Sequencing (NGS), species-specific and host-preference diagnostic markers were identified in the nuclear genome and developed into qPCR assays. Clade-specific assays were able to detect low amounts of P. cubensis sporangia sampled using spore traps as a first step to develop a biosurveillance system for CDM. Assays to detect resistance to Carboxylic Acid Amide (CAA) and Quinone Outside Inhibitor (QoI) fungicides were also developed and indicated widespread fungicide resistance in both clades for QoIs but showed that clade 2 isolates are less sensitive to CAAs than clade 1. Similarly, effector repertoire analyses in clade 1 and clade 2 isolates revealed effectors with clade specific occurrence or expression during host colonization. Overall, findings indicate that understanding population clade composition is critical for effective management of P. cubensis using crop-specific cultural practices, chemical control, and host resistance.

Decoding the secret language of soils: chemical signalling in the rhizosphere and it’s consequences for plant health

“Despite the staggering technological achievements of agriculture, we owe our entire existence on this planet to a six-inch layer of soil and the fact that it rains”. The soil is the foundation of most terrestrial life on the Earth yet soil as a resource and its staggering complexity is often ignored, undervalued and under appreciated, non-more so than the amazing array of organisms that make soil their home. The soil is a repository of information as well as an information superhighway where signals are exchange between the soil organisms including plants, animals and microbes. These, usually chemical, signals have been hard to detect and to decode but advances in analytical methodologies now allow us to eaves drop on these conversations as never before and understand how plants can form beneficial symbiosis as well and sense and defend themselves against pathogens. Here I have selected some examples of how soil organisms communicate with each other and the wider consequences of those conversations for soil ecosystems and plant health

Are taxonomists fiddling while Rome burns?
As the dust settles on the international climate negotiations at COP 26, Glasgow, the urgency to preserve biodiversity has been put in sharp focus. The preservation of biodiversity is a good thing. It is good for reducing both CO2 levels and global warming through maintaining forests. And it is good for agriculture, food security and biosecurity. Biodiversity keeps soils fertile, air and water clean, and provides natural predators that reduce pests and diseases. Taxonomists play a critical role in the preservation of biodiversity. Taxonomists seek to discover and describe all forms of life on Earth, including bacteria, fungi, nematodes and viruses. Yet something is not working. Take the Fungi as an example. Of an estimated 3 million species on Earth, only 150,000 (5%) have been described since modern taxonomy started with Carl Linnaeus’ Species Plantarum in 1753. In this calendar year 2021, only 2,784 new fungal species were added, which is less than 0.1% of the estimated total. What has gone wrong? Are taxonomists the solution or the problem?
