Due to increased availability of wheat genome information over the past year, it has become easier for researchers to pin-point where the genetic controls for traits of economic importance are in the complex wheat genome. Although this technology has little to do with the typical day-to-day activities of a farmer, it has everything to do with unlocking a world of opportunity for the future of wheat in Canada.

Meet Dr. Belay Ayele, Associate Professor in the Department of Plant Science at the University of Manitoba. Dr. Ayele lives and breathes plant hormones, which are also known commonly as plant growth regulators (PGRs) by crop producers and related industries. While completing his master’s degree at Wageningen Agricultural University in the Netherlands, he became interested in focusing his studies on the biology of seed germination and dormancy, two traits that are critical in controlling pre-harvest sprouting, which refers to the germination of seeds prior to harvest, in cereal crops. Pre-harvest sprouting is one of the most important problems in the production of wheat and barley, two major cereal crops of Canada, as it downgrades the quality of the grains, thereby causing financial loss to the producers.

While completing his PhD in at the University of Alberta, Edmonton, Alberta, Dr. Ayele studied one of the plant hormones, gibberellin (GA) and its production pathway, the GA Metabolic Pathway, intensively.

“GA is involved in regulating crop growth and development from seed to seed” explained Dr. Ayele as he discussed what drew him to studying these hormones, “I wanted to understand how these compounds are produced and degraded in plants because it is involved in regulating a wide range of traits of agronomic importance in crop plants. Therefore, for someone who is passionate about making a difference in the breeding world, this seemed to be the perfect path for Belay to take. To study more about this plant hormone, Belay went to RIKEN Plant Science Center in Japan for his postdoctoral research, as most of the discoveries about GA come from the research labs of Japanese scientists at RIKEN.

“There wasn’t a lot of information on the variation in wheat plant hormones when I first started school. Wheat is a major crop in Canada and the world,” Ayele mentioned, as he explained his decision to focus on wheat during his PhD, “If I work on a major crop I know I can make a difference.” 

Among the critical times in a farmer’s year are seeding and harvest. During seeding, farmers make sure that they have high quality seeds to ensure fast and uniform germination, and seedling establishment. The seeds need to be planted at an optimal time and in favourable environmental conditions so that they germinate and emerge from the soil with vigor. However, conditions such as excess moisture occurs during spring, either before or after planting, for many Manitoba crop producers, causing a delay in planting or affecting the stand establishment or growth of the crop. The occurrence of undesirable weather such as cool and moist summer conditions after crop maturity are the other sources of problems in wheat and barley production, since such weather conditions cause pre-harvest sprouting of the grains. After harvesting, grains are subjected to quality evaluation. Lower quality grains such as those affected by pre-harvest sprouting are brought to a feed mill to be sold at lower price into the feed market for livestock, while the high quality grains are sold into the international market to be made into food that will be consumed by humans all over the world. In general, during both critical times, the environmental conditions that crop is subjected to play a very important role in determining grain yield and quality.

In his research lab, Belay has growth facilities that allow his research team to control the environmental conditions that a plant is subjected to, making it entirely possible to control the growth conditions, ensuring the crop grows to its full genetic potential – unfortunately, not something that farmers are able to do. Dr. Ayele’s research, partially funded by the Manitoba Wheat and Barley Growers Association (MWBGA), is about finding the right combination of genes that will allow breeders to develop a wheat and barley varieties that can tackle abiotic (weather related) stress factors such as preharvest sprouting of grains and the extremes of soil moisture; problems constantly challenging Manitoba wheat and barley growers. Research on excess moisture in crop agriculture is considered a ‘gap area’ in Canada by many.

To help ensure that a wheat plant does well, “we need to have a balance between dormancy and sprouting,” Ayele explains, “the two hormones responsible for controlling this are GA and abscisic acid (ABA)”. If a seed has too much GA, the seed will germinate very easily, often resulting in a near-mature wheat plant that has seeds sprouting while it’s still standing. The other extreme is that a seed with too much ABA will not germinate for a long time, if at all.

“We have to look at both sides.”

When developing new wheat varieties, finding the ‘happy medium’ between these two hormones is crucial. Breeders seek out varieties like this, which possess intermediate level of dormancy, as they are the best option for farmers and can help produce grains that can readily germinate after harvest but not before harvest so that the farmer does not need to worry about the occurrence of field sprouting. Through his work, Dr. Ayele has been able to associate plant hormone changes with certain genes related to ABA and GA on the wheat genome. Newly expanded genomics technologies will enable breeders to screen new varieties being bred to see which ones have these desirable traits.

“The wheat genome is very complex,” Dr. Ayele went on to explain just how complicated wheat is, “it has three genomes and each gene has six copies.” Having the technology available to tap into the wheat genome information makes it easier to generate tools that can aid the breeders to develop new varieties that can withstand different environmental stress conditions.

Ayele also does research with the GAs and ABA hormones in barley which is, according to him, “even more tricky” to find a balance than in wheat. Farmers want barley to sprout quickly and evenly in the spring during seeding, maltsters want the same quick, even sprouting in the malt house, but neither want the barley sprouting while the crop is standing in the fall or the harvested seeds are in storage. Finding this balance requires researchers to be extra picky with the selection of genes in barley.

Dr. Ayele’s research is intended to provide breeders with the tools they need to develop new varieties needed for wheat and barley so that the two crops can remain competitive within domestic Canadian markets, as well as in international markets. The Manitoba Wheat and Barley Growers Association is proud to be a major funder of this project, alongside the Western Grains Research Foundation, Natural Sciences and Engineering Research Council of Canada, Canadian Foundation for Innovation, and two Growing Forward 2 programs (the National Wheat Improvement Program and the Manitoba Grain Innovation Hub).

On December 17th, 2018, On-Farm Network (OFN) participants for 2018 were invited to attend the OFN Appreciation Event at Kelburn Farms, south of Winnipeg, MB. Attendants were presented with research results from on-farm trails and treated to dinner and networking opportunities throughout the evening.

The OFN is a network of on-farm research related to pulse, soybean, wheat and corn crops that is directed by the Manitoba Pulse and Soybean Growers (MPSG), and funded by MPSG, the Manitoba Wheat and Barley Growers Association (MWBGA) and Manitoba Corn Growers Association (MCGA). Research is conducted on real, working farms and farmers are involved in the process, in collaboration with research specialists. The willingness from farmers to assist in this research is the one of the reasons that the OFN has been so successful. This event is a way to show these farmers how much their contribution means, as well as gauge interest from farmers to continue participating in the years ahead.

Greg Bartley, On-Farm Specialist with MPSG, sees first-hand every year the benefits that this program has for Manitoba farmers:

“Farmers have a lot of new products that are being offered on the farm or have adopted products or practices without actually knowing the benefit of that product of practice on their farm. The On-Farm Network provides a platform for farmers to test these products and practices with scientific integrity that allows them to make decisions on their farms.” Bartley guides his team along the way from before trials begin, to after the reports have been finalized. However, when the work is done, he finds it rewarding to bring everybody who was involved together:

“Seeing participants and researchers interacting with each other and sharing results, ideas and knowledge is definitely a highlight of this event for me,” Bartley reflects. The MPSG, MWBGA and MCGA are currently working on finalizing the protocols for 2019 projects and are looking forward to another great year of the On-Farm Network.

Meet a Producer – Combine to Customer

November 26th, 2018

Wheat growers, Jeff and Sheila Elder, discuss the impact that attending the Combine to Customer workshop has had on their farm.

Jeff Elder and his wife, Sheila, are proud to be operating a fifth-generation, family farm in Manitoba. Jeff, having grown up on the farm, has been learning about the agriculture industry his entire life, while Sheila, originally from in town, has always been “supportive and willing to learn” about the agriculture industry. A few years ago, when the chance to participate in a Combine to Customer workshop was presented, both jumped at the opportunity!

“We learned so many things at the course. It seemed that every minute of our time was jam packed with learning and networking experiences,” Jeff and Sheila went on to explain a few of the many things that they were able to learn over the course of the program.
“We learned about grain grading and analysis, flour milling, bread baking, noodle making, pulse processing, malt production and beer brewing. We also learned about many of the market development activities that take place behind the scenes, as well as governance, rail monitoring and variety development.”
Three Combine to Customer workshops are scheduled to be held at the Canadian International Grains Institute, commonly known as Cigi, in 2019. Each workshop is four days long and is geared towards informing Canadian grain growers on where today’s evolving grain industry is heading and what needs to be done to stay competitive and meet the ever-changing requirements of domestic and international grain buyers.
“Attending as a couple gave us a lot of ‘food for thought’ [on the farm] and we have discussed things we’ve learned many times over the past year – it also created more interest in continuing education and workshops.” One of the biggest things that the Elder’s became more aware about included where all of the dollars from grain deductions go.
“Our biggest take away from the course was realizing how much goes on behind the scenes that supports our industry.”
The workshops are designed to engage and inform growers in a unique way, and will help anyone gain a better understanding about the agriculture industry as a whole. Increasing awareness about how the industry works at the consumer level is a huge takeaway from the program as well.
Today, people’s idea of ‘time well spent’ can vary. However, if anyone understands the value of time, it’s farmers. When asked if they considered the Combine to Customer workshop to be ‘time well spent’, Jeff and Sheila did not hesitate one bit with their response,
“Yes!- Anytime that there is an opportunity to mention this course to fellow farmers, we do. It was one of the best workshops that we have ever attended.”
There are currently several spots left in all three 2019 workshops. The dates of the upcoming workshops are: February 10-13, February 19-22 and March 10-13. Cigi covers all expenses for participants and encourages growers to sign up!
