Plant Physiology Article of the Week: Pathways to de novo domestication of crop wild relatives
The spotlight is on Robert J. Schmitz, Erich Grotewold, and Maike Stam. Their review article discusses the features of cis-regulatory sequences in plants, technologies enabling their identification, characterization and validation, their organization into functional cis-regulatory modules, their genomic distributions with respect to target genes, and the role of transposable elements in their evolution.

The Plant Cell Article of the Week: Phosphatidic acid modulates MPK3- and MPK6-mediated hypoxia signaling in Arabidopsis
The spotlight is on Ying Zhou, De-Mian Zhou, Wei-Wei Yu, Li-Li Shi, Yi Zhang, Yong-Xia Lai, Li-Ping Huang, Hua Qi, Qin-Fang Chen, Nan Yao, Jian-Feng Li, Li-Juan Xie, and Shi Xiao. Their article demonstrates that phosphatidic acid modulates plant tolerance to submergence by affecting membrane integrity and MPK3/6-mediated hypoxia signaling.

.CHANGING CULTURES AND CLIMATES
The mission of Changing Cultures and Climates is to provide information that supports and promotes diversity, inclusivity, and equity in the international plant science community so that it grows to more accurately reflect that of our larger, global society.
Unrealized Potential from Smaller Institutions: Four Strategies for Advancing STEM Diversity
From Cell
Diversity within science, technology, engineering, and mathematics (STEM) remains disturbingly low. Relative to larger, highly funded universities, smaller schools harbor more diverse student demographics and more limited resources. Here, we propose four strategies leveraging the unique advantages of smaller institutions to advance underrepresented scholars along STEM pathways. Unveiling the hidden curriculum, extending research experiences to more students through CURE classes, inducting diverse students into the world of research through online journal clubs, and building inter-institutional mentorship networks all synergize to empower and retain historically marginalized scholars.

.FROM THE FIELD
GAIA: An 'eEcosystem' of Aggregated Information for Plant Biology
From the University of Toronto
Currently, there is a plethora of scientific data available online through many different tools, databases, repositories, and websites, making it difficult for researchers to find the information for their prospective investigation. When the Multinational Arabidopsis Steering Committee (MASC) conducted a 2018 bioinformatics survey, they found that researchers have expressed a strong desire to have data centralized. Inspired by this request, the General Agricultural Intelligent Agent (GAIA) was created.

The Layered Effect: A Single-Cell Map of Corn's Root Reveals a Regulator of Cellular Diversity
From New York University
A new study uses novel single-cell profiling techniques to reveal how plants add new cell layers that help them resist climate stressors like drought or flooding. The research focuses on corn — a critically important crop around the world — in an effort to create a cell-by-cell map of the plant's root system, which mediates drought stress and absorbs nutrients and fertilizer from the soil.

Plant Pathogen Evades Immune System by Targeting the Microbiome
From the University of Cologne
Scientists increasingly recognize that an organism's microbiome — the totality of bacteria and other microbes living in and on it — is an important component of its health. For humans as well as other animals, particular microbes inhabiting the gut and the skin have beneficial effects. This is similarly true for plants. Moreover, it has been established that plants can "recruit" beneficial microbes from their environment, for instance from the soil surrounding the roots, to help them withstand disease. At the University of Cologne, together with Dr. Nick Snelders lead author of the study Dr. Thomma hypothesized that if plants can do this, perhaps some pathogens have "learned" to perturb this "cry for help" and disturb the plant's microbiome in order to promote invasion.

Getting to the Root of Plant-Soil Interactions: Optical Instrument to Give Clearest 3-D Images Yet of Rhizosphere
From the Georgia Institute of Technology
At just a few inches underground, the rhizosphere — the thin strip of earth that includes the soil-root interface — has so far been difficult to visualize on site. If scientists can build instruments that capture in real-time clearer images of the physical associations of microbes attached to roots, along with the oxygen-carbon-nitrogen chemical exchanges they mediate, it could help mitigate the effects of climate change and lead to the development of more sustainable fuels and fertilizers. "From a microbiological perspective, we have catalogued what microbes are in the root zone and how abundant they are," said Joel Kostka, professor in the School of Biological Sciences and School of Earth and Atmospheric Sciences at Georgia Tech. "But there's been very little work to understand their dynamics under real soil conditions."

Plant Immunity, Defenses, and the Circadian Clock
From The University of Washington
Plants are more like us than we think — they are complex organisms that have immune systems and can react to environmental changes. Two biology labs at UW are studying these reactions and how they can be affected by different environments. The first lab is led by Adam Steinbrenner, an assistant professor in the department of biology. Steinbrenner studies the immune systems of bean varieties in response to threats from caterpillars. Takato Imaizumi, a professor in the department of biology, studies how plants know when to flower based on the circadian rhythm and how it affects plant-pollinator reactions.

Global Database of Plants Reveals Human Activity Biggest Driver of Homogenization of Plant Communities
From Harvard University via Phys.org
Species extinction, the introduction of non-native plants, climate change, and pollution are all major drivers of changes in biological communities due to human activity. Though these patterns have been well studied, most investigations focus on only one of these drivers and often in a localized area rather than more globally. In a study published in Nature Communications researchers have compiled a dataset of over 200,000 plant species worldwide to demonstrate the extent to which species extinctions and non-native invasive plants reorganize plant communities in the Anthropocene, the current geological age dominated by human activity.

Host and Resident Bacteria Join Forces to Control Fungi in Plant Roots
From the Max Planck Institute for Plant Breeding Research
In nature, the roots of healthy plants are colonized by complex microbial communities of bacteria and filamentous eukaryotes (i.e., fungi and oomycetes, the composition of which profoundly influences plant health. Maintaining a microbial equilibrium in their roots is very important for plants to remain healthy, however, the means by which this is achieved by plants is still largely unknown. Now, in a new study published in PNAS, Stéphane Hacquard and his colleagues from the Department of Plant-Microbe Interactions at the MPIPZ in Cologne, Germany, shed light on the host and microbial factors that are required to maintain a beneficial relationship between plant roots and their diverse microbial partners.
