A recent study by Pi et al. decoded previously unknown mechanism through which a virus manipulates the plant defense pathway for successful infection. Focusing on the interaction between barley and the devastating barley stripe mosaic virus (BSMV), researchers identified a critical regulatory hub centered…

Salicylic acid (SA) is best known as a central hormone orchestrating plant immune response, including the hypersensitive reaction and systemic acquired resistance. Beyond defense, SA also influences plant growth and development, highlighting a delicate role in balancing the trade-off between immunity…

Through their roots, plants live in close association with many soil microorganisms, including fungi and bacteria that help them grow. Beneficial fungi help plants cope with stress, and in return, the plants provide them with nutrients. A key part of this exchange is the movement of sucrose, a sugar…

Plants depend on innate immune systems to recognize microbial invaders or damages that signal danger. This discrimination must be extremely precise: they must welcome beneficial microbes that support nutrient uptake and growth while defending against pathogens that threaten survival. A long-standing…

If you’ve ever looked closely at a tomato flower, you might have noticed that its anthers cluster together in the center of the flower, making the pollen inaccessible to most insects. Tomato flowers are an example of a buzz pollinated flower, in which the pollen is released by the physical shaking…

The urgent need to support and sustain plant research is indisputable, but sometimes plant education, the foundation upon which research rests, doesn’t get the same support. In January 2025, a group of dedicated educators (mostly higher education and outreach) spent two days together to strategize…

Opinion: Genomic studies hint at what makes a tree a tree This is such an engaging and though-provoking review article. I’d love to ask a group of students to think about what makes a tree a tree, including such questions as: How do we define trees? Do woody plants share a single origin? How many…

This is an interesting and engaging review article, written by a team from Bayer US Crop Science, on how mutations (broadly defined) have benefited plant domestication and breeding. While it briefly covers the basics, such as population genetics, it really focuses on demystifying and normalizing the…
