The plant immune system is often described as having two parts, one which recognizes extracellular conserved microbial signals (pattern-triggered immunity: PTI) and one which is stimulated by the presence of specific microbial effectors (effector-triggered immunity: ETI). Through a forward-genetic screen, Mang et al. identified a pair of receptor-like kinases ANX1 and ANX2 that are negative […]
Review. Genomic selection in plant breeding: Methods, models, and perspectives In future years, climate change may cause significant economic losses to countries worldwide. Consequently, genetic improvement of crops fit for drought-stressed and semi-arid regions is becoming a must. In this review, Crossa et al. assess the advances in genetic selection (GS) and genomic-enabled prediction (GP) […]
By Jozef Samaj, George Komis, Dominik Novak, Miroslav Ovecka, Olga Samajova Abstract After the establishment of advanced fluorescence microscopy methods and the development of numerous fluorescent proteins it is possible to follow the organization and dynamics of most organelles and subcellular compartments in cells of living plants. Nowadays, it is possible to address subcellular architecture […]
How does a flat leaf form? Previous studies have indicated that the formation of a flattened blade depends upon a boundary layer between the upper and lower cell layers, and that mobile small RNAs contribute to this boundary, but how this occurs is not fully resolved. For example, although the small RNA tasiRNA is present […]
All cells need iron (Fe), which is frequently limiting for life. Plants (like other organisms) have complex strategies for uptake of Fe from their environment. Studies in the green alga Chlamodomonas have demonstrated that these organisms are able to prioritize certain pathways when Fe is limiting, a process called “Fe sparing”. Hantzis et al. used […]

This past year at ASPB we’ve been thinking a lot about how we can support early-career researchers no matter their career goals. One of the motivations for developing the Plantae platform has been to provide an online home for plant scientists across the globe and career spectrum, to allow informal communities and learning groups to […]
By Romy Schmidt, Daan A Weits, Claudio FJ Feulner, Joost T. van Dongen Plants grow in a dynamic environment and continuously face numerous stress conditions in parallel. This fluctuating environment pushed the evolution of extensive metabolic flexibility (Sweetlove et al., 2010; van Dongen et al., 2011). Flooding is an example of an environmental condition that […]
By Thanin Chantarachot and Julia Bailey-Serres The export of an mRNA from the nucleus to the cytoplasm begins an odyssey of dynamic regulation that determines the location, longevity and use of the transcript in the production of polypeptides by ribosomes in plant cells. Recent leveraging of mutants, imaging of fluorescent proteins and ‘omics’ of protein […]
