    Sorgoleone with Drs. Sakiko Okumoto, Bill Rooney, and Guntur Subbarao

    "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 If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/csc2.70066 This paper is always freely available.

    Rescuing Potato from Buckwheat Volunteers with Dr. Andrew McKenzie-Gopsill

    "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.

    Genomic Selection with Dr. Jianming Yu

    "Genomic Selection: Essence, Applications, and Prospects" with Dr. Jianming Yu Genomic Selection is a plant breeding innovation that aims to speed plant breeding by using predictions from a training model enabled by genomics and statistics to guide the breeding decisions. With around thirty years of history around this innovation, it was about time to develop a review on it. Enter Dr. Jianming Yu and his team of coauthors. This episode, we skate the surface of a topic that could go down for miles, covering key areas of genomic selection, what it is, how to use it, and where we can aim to go in the future. Tune in to learn: ·         How genomic selection was developed ·         Why genomic selection should be seen as an innovation in rather than alternative to plant breeding ·         Why growing out crosses still matters ·         How AI could be integrated to further genomic selection If you would like more information about this topic, this episode's paper is available here: https://doi.org/10.1002/tpg2.70053 This paper is always freely available.
