  Serious Problems posed by Puccinia psidii in Australia  
 

As readers of this Newsletter will be aware, a rust fungus infecting members of the Myrtaceae was found in New South Wales in about April 2010, and a number of papers have been published since then, reporting the developing situation.

 

The first was Carnegie A J, Lidbetter J R, Walker J, Horwood M A, Tesoriero L, Glen M and Priest M (2010) Uredo rangelii, a taxon in the guava rust complex, newly recorded on Myrtaceae in Australia. Australasian Plant Pathology 39:463–466, as reported in the ISPP Newsletter of August 2010.

 

Then came Carnegie A J and Cooper K (2011) Emergency response to the incursion of an exotic myrtaceous rust in Australia. Australasian Plant Pathology 40: 346-359, referred to in the ISPP Newsletter of August 2011.

 

The latest is Carnegie A J and Lidbetter J R (2011) Rapidly expanding host range for Puccinia psidii sensu lato in Australia. Australasian Plant Pathology volume 40 (6) and published on-line on 26 August 2011 at < http://dx.doi.org/10.1007/s13313-011-0082-6 >.

 

The recent discovery of teliospores in NSW indicates that the rust in Australia is a strain (with tonsured urediospores) of P. psidii sensu lato. Key forestry species were tested in artificial inoculation experiments. Several species of Eucalyptus were susceptible (viz. E. pilularis, E. cloeziana, E. agglomerata and E. grandis ), as was Melaleuca quinquenervia.

 

In Australia, P. psidii s.l. has now been found on 107 host species in 30 genera, including species in Angophora, Asteromyrtus, Austromyrtus, Backhousia, Callistemon, Chamelaucium, Choricarpia, Decaspermum, Eucalyptus, Eugenia, Gossia, Lenwebbia, Leptospermum, Lophomyrtus, Melaleuca, Metrosideros, Myrtus, Pilidiostigma, Rhodamnia, Rhodomyrtus, Ristantia, Stockwellia, Syncarpia, Syzygium, Tristania, Tristaniopsis, Ugni, Uromyrtus and Xanthostemon.

 

Species in nurseries and gardens that are severely affected include Gossia inophloia, Agonis flexuosa, Syzygium jambos and S. anisatum while species that are severely damaged in native bushland include Rhodamnia rubescens, Rhodomyrtus psidioides, Choricarpia leptopetala and Melaleuca quinquenervia.
 
     
   
  The Importance of Plant Science to Humanity  

How do we feed our children’s children?

 

Which crops must be grown and which sacrificed, to feed the billions?

 

When and how can we simultaneously deliver increased yields and reduce the environmental impact of agriculture?

 

These are just some of the crucial questions facing the global community today which plant science must address in order to ensure a sustainable future for humanity.  Yet while the importance of plant science and botany is undeniable, in a growing number of countries and institutions there are threats to our ability to populate these fields of study with our brightest and best young minds and in sustaining academic activities in these subject areas.  A cause for alarm in the UK was cited in the June 2011 issue of the ISPP Newsletter.  Now comes the rousing view in a new article that Plant Scientist should take its rightful place beside Doctor, Lawyer and Vet in the list of top professions to which capable young people aspire.
 

This challenge is made in a letter entitled “One hundred important questions facing plant science research” and published on-line on 22 August 2011 in New Phytologist. Its fourteen authors lead by Professor Claire Grierson of the University of Bristol undertook on-line consultation over a 3-month period in recent years among plant scientists in and outside of the UK and among farmers and through the press. The consultation was about key issues that future plant scientists should be addressing, and resulted in the compilation of nearly 400 questions. A panel from the academic, commercial, and public service communities that produce or benefit from plant science research selected 100 of them for the letter.

 

The panel grouped the questions into five broad areas: society, environment and adaptation, species interactions, understanding and utilizing plant cells, and diversity. They are detailed in the letter.  The panel concluded that plant science is central to many of the issues facing humanity. “Secure food production and quality remain key issues for the world in the 21st Century, and the importance of plants extends well beyond agriculture and horticulture because of declining fossil fuel reserves, climate change, and a need for more sustainable methods to produce fuel, fibre, wood, and industrial feedstocks”.

 

Further conclusions were as follows:

  • As plant science becomes increasingly important, the brightest and best must be attracted to careers in plant research.

  • Steps are needed to improve school education to show the most interesting or relevant aspects of plant science, and to encourage further study at university.

  • Making the best possible progress will require exceptional people.

     
   
     
  FAO Vegetable IPM Program in South & Southeast Asia
 

For over a decade, this Program has worked with government and nongovernmental organizations and carried out farmer education and participatory research activities to promote and support Integrated Pest Management (IPM) in vegetables by Asian smallholder farmers. IPM is an ecological approach to crop production and protection that combines different management strategies and practices to grow healthy crops and minimize the use of pesticides.

 

The training approach used in the Program is mainly a Farmer Field School (FFS). In an FFS, 25-30 farmers meet each week along with qualified extension staff and/or experienced farmers. Employing informal methods, a field is used as the resource for discovery-based learning. Farmers gain management skills, generate knowledge, carry out experiments and learn how to make better informed decisions. This seeks to empower the application of the principles learned to other spheres aimed at improving rural livelihoods.

 

The twenty-seventh session of the Asia and Pacific Plant Protection Commission (APPPC) was held in Manila, Philippines, from 15 to 19 August, 2011.  Forty-seven delegates from 19 contracting governments attended the meeting. There were also 13 observers from various organizations including Pesticide Action Network – Asia and Pacific, USDA and the Secretariat of the Rotterdam Convention.

 

A Progress Report of the Standing Committee on Integrated Pest Management was delivered by the outgoing Chair from the Philippines. It highlighted the incidence of pests and diseases in APPPC member countries as a result of crop production intensification under the national food security agenda and how the problems can be adequately addressed by breakthroughs in IPM given the political will to invest in farmer education in IPM. Work-plans for 2012-2013, presented by the incoming Chair from Vietnam, identified lead-counties for each activity as the People’s Republic of China, Thailand, Vietnam, Cambodia, Malaysia and the Philippines for different activities.
 
     
   
  Indian Phytopathological Society and coming Symposium

The Indian Phytopathological Society (IPS) is one of the largest societies of plant pathologists in the world. It was established in February 1947 at the Indian Agricultural Research Institute, New Delhi. The constitution was ratified at the first annual general body meeting of the Society held in January 1948 when 156 charter members took part. IPS now has about 2,000 members located in more than 50 countries. It focuses on the fields of Mycology, Fungal Pathology, Bacteriology, Virology, Phytoplasmology and Nematology. IPS has published its journal Indian Phytopathology since early 1948.

  APS Journals – Editor’s Selections
 

Dr R Michael Davis, Editor-in-Chief of Plant Disease, picked from the September issue, a paper titled “Variability Among Forecast Models for the Apple Sooty Blotch/Flyspeck Disease Complex” by D R Cooley and colleagues. They examined sources of variability among available models that forecast apple diseases. Leaf wetness duration was highly variable, but canopy density, tree size, and cultivar also affected accuracy of models. The study is applicable to many forecasting models and shows the types of detailed analysis needed before any single model is universally applied. Read more...

 

Dr Gary Stacey, Editor-in-Chief of Molecular Plant Microbe Interactions, selected from the September issue, a paper by Chiara Volpi et al from Italy titled “The Ectopic Expression of a Pectin Methyl Esterase Inhibitor Increases Pectin Methyl Esterification and Limits Fungal Diseases in Wheat”. It showed that transgenic expression in durum wheat of the inhibitor derived from golden Kiwi fruit caused an increase in pectin methylation and an increase in resistance to Bipolaris sorokiniana and Fusarium graminearum.

Dr Niklaus Grunwald, Editor-in-Chief of Phytopathology, picked a paper titled “Investigating the Genetic Structure of Phytophthora capsici Populations” by L M Quesada-Ocampo et al. The soil-borne pathogen affects many crops in the Solanaceae, Cucurbitaceae, Fabaceae and other families. Isolates from six continents, 21 countries, 19 states in the USA and from 26 host species were genotyped for four mitochondrial and six nuclear loci. Bayesian clustering revealed some population structure by host, geographic origin and mefenoxam sensitivity, with some clusters occurring more or less frequently in particular categories. This highlights the importance of including isolates from all detected clusters for development of diagnostic tools, fungicides, and host resistance. Read more...

The next, the XXVIII Congress, is scheduled for São Paulo, Brazil in May 2013.

Workshops are also held between congresses for discussions among specialists on key issues affecting the industry. In May 2012, its 10th Pathology Workshop will be held in Nanning, China, as shown in “Coming Events” and
the Workshop web-site.

 
     
 
Bacterial disease of betel vines in Taiwan
 

Betel-vines (Piper betle, Piperaceae) showing leaf blight symptoms were observed during 2008 in central Taiwan. Infections resulted in 30 to 70% losses in leaf production. Symptoms on leaves were small, necrotic and water-soaked spots that progressed to circular or irregularly shaped brown lesions with chlorotic haloes. The presence of Acidovorax citrulli was found on diseased plants and this was the first report of the bacterium naturally infecting a non-cucurbit. Inoculation studies showed that betel-vine strains could infect Cucumis melo.

 

See: Deng W L, Huang T C, Tsai Y C (2010) First report of Acidovorax avenae subsp. citrulli as the causal agent of bacterial leaf blight of betelvine in Taiwan. Plant Disease 94 (8), 1065-1065.

  Seed China News  
 

The first issue of “Seed China News” came out in January 2011 as volume 1 issue 1, and it may be down-loaded by clicking here.

 

It starts by stating that China is the second largest seed producing country in the world but that its domestic market is currently in turmoil, with too many companies with generally weak R&D capabilities. It faces great challenge from many overseas seed companies. The Ministry of Agriculture is formulating a new policy of "Seed Management Regulations". This is likely to cause the number of seed companies in China to be reduced because many existing companies will be unable to meet the requirements.  Overseas seed companies continue to strengthen their business in China, with for example expanding vegetable seed business in Guangdong, cooperating with domestic companies.

 

The news then covers over fourteen pages about activities involving seeds of different crops and for different regions of China.
