"Synthesis, function, and genetic variation of sorgoleone, the major biological nitrification inhibitor in sorghum" with Drs. Sakiko Okumoto, Bill Rooney, and Guntur Subbarao
When we fertilize our crops, some of the nitrogen from that fertilizer gets converted into different forms through processes called nitrification and denitrification. When non-plant available forms of nitrogen exit the soil through water or as gas, it's a serious environmental problem. Thankfully, plants have some pretty nifty ways to prevent nitrification, such as biological nitrification inhibition or BNI, a process that manages the bacteria that cause nitrification. In this episode, Sakiko, Bill, and Guntur join me to discuss sorgoleone, a product of sorghum roots that plays a key role in the BNI process.
Tune in to learn:
·         What sorgoleone is
·         How it helps
·         What challenges breeders face in increasing it
·         What challenges researchers face in moving this research out into farms

BNI consortium conference: JIRCAS organizes International BNI-consortium meetings in Tsukuba, Japan, every two years. The next BNI-consortium meeting will be in the first week of December 2026. Most BNI-researchers working with JIRCAS BNI-team are invited for this meeting along with researchers who wish to enter into this research and establish collaborative linkages with other members of this group.

We're trying something a little bit different. In addition to our regular episodes with Abby, we'll be adding a monthly bonus episode with Jim Cudahy, the CEO of the Societies. In this first episode, Jim has a chat with the three Society presidents, discussing current challenges and opportunities for the Societies, including ways that members can get the most out of our programs, but guests will vary a lot from there! Please give a listen and let us know what you think. If there are specific guests or topics you want us to cover, let us know!

"The critical period of cover crop management: A framework for maximizing biomass potential and minimizing volunteers with buckwheat" with Dr. Andrew McKenzie-Gopsill
Buckwheat can be a powerful driver of ecosystem services in potato rotations grown in Canada, but with its long-lived seeds and ability to make a whole lot of them in a short time, it can also pose a serious volunteer problem. In this episode, Andrew joins me to discuss how creating a framework to reduce volunteers can help keep this helpful plant from turning into a fearsome weed.
Tune in to learn:
·         How potato farming is done in Canada
·         What ecosystem services buckwheat provides
·         What qualities can turn buckwheat from a helpful crop to a difficult to control weed
·         How combining tools from weed management can help keep buckwheat under control

"Within-family genomic selection in strawberry: optimization of marker density, trial design, and training set composition" with Dr. Joshua Sleper
If plant breeding were a poker game, you'd have to play a lot of hands to beat the house. Quantitative genetics hopes to give players an advantage by recognizing patterns that can point to future success. In strawberry, a genetically complex and labor-intensive plant, this is particularly important. This episode, Joshua join me to discuss his work using quantitative genetics to help give strawberry breeders a hand.
Tune in to learn:
·        How some plants have "sticky cards" in their genetics
·        What challenges strawberry breeders face
·        How many clones are really enough
·        What lies on the horizon for strawberry breeding
