Plant Physiology Article of the Week: Ethylene Augments Root Hypoxia Tolerance via Growth Cessation and Reactive Oxygen Species Amelioration
The spotlight is on Zeguang Liu, Sjon Hartman, Hans van Veen, Hongtao Zhang, Hendrika A. C. F. Leeggangers, Shanice Martopawiro, Femke Bosman, Florian de Deugd, Peng Su, Maureen Hummel, Tom Rankenberg, Kirsty L. Hassall, Julia Bailey-Serres, Frederica L. Theodoulou, Laurentius A. C. J.

Achieving STEM Diversity: Fix the Classrooms
From Science
Jo Handelsman and co-authors share evidence-based strategies to encourage undergraduates from historically excluded communities (HECs) to pursue their interest in science majors. These include active learning including CUREs (Course-based undergraduate research experiences), making the classroom more inclusive by actively incorporating major- and minor- affirmations (some great tips here), and including stories of scientists from HECs in the course materials. As well as strategies that can be employed by individual instructors, this article also describes strategies that can be implemented by academic leaders and national level agencies.

Recognizing Plant Physiology Authors
Meet Fabiola Muro-Villanueva, first author of “H-lignin can be Deposited Independently of CINNAMYL ALCOHOL DEHYDROGENASE C and D in Arabidopsis.” She is a currently a postdoctoral Research Assistant at Purdue University, where she earned her PhD in Biochemistry. Fabiola grew up on a farm, which exposed her to agriculture from an early age and sparked her interest in plants and how they function. Her current research focuses on understanding the link between lignin content and composition and plant dwarfism. In her free time she enjoys cooking, running, barre, and traveling.

How Invading Pathogens Switch Off Plant Cells' Defenses
From Phys.org
Many disease-causing bacteria are able to inhibit the defense mechanisms in plants and thus escape dissolution by the plant cell, a process known as xenophagy. Animal and human cells have a similar mechanism whereby the cell's defenses "eat" invading bacteria — yet some bacteria can inhibit the process.

Palms at the Poles: Fossil Plants Reveal Lush Southern Hemisphere Forests in Ancient Hothouse Climate
From EurekAlert!
For decades, paleobotanist David Greenwood has collected fossil plants from Australia – some so well preserved it’s hard to believe they’re millions of years old. These fossils hold details about the ancient world in which they thrived, and Greenwood and a team of researchers including climate modeler and research David Hutchinson, from the University of New South Wales, and UConn Department of Geosciences paleobotanist Tammo Reichgelt, have begun the process of piecing together the evidence to see what more they could learn from the collection.

Rare Plant Species Discovered in Smithville, Tennessee
From News Channel 5
Tennessee Tech University students have discovered a plant species so rare that it is still new to science — first described in 2020. The plant is called the Cumberland pagoda-plant, scientific name Blephilia woffordii.

Scaling New Heights With New Research Showing How Plants Can Grow at Altitude
From ScienceDaily via University of Nottingham
A new study has found that plant species are adapted to the altitude where they grow by 'sensing' the oxygen levels that surround them. Altitude is an important part of plant ecology with at least 30% of plant species diversity contained in mountains and climate change is leading to the retreat of alpine species and some crops to higher altitudes.

World's Largest Plant Discovered in Australia
From CNN
The world's largest living plant has been identified in the shallow waters off the coast of Western Australia, according to scientists.
The sprawling seagrass, a marine flowering plant known as Posidonia australis, stretches for more than 112 miles in Shark Bay, a wilderness area protected as a World Heritage site, said Elizabeth Sinclair, a senior research fellow at the School of Biological Sciences and Oceans Institute at The University of Western Australia.

The Grass May Be Greener on Old Mine Sites As WVU Researchers Test Resiliency of Bioenergy Crops
From ENN
West Virginia University researchers are working to better understand how climate change may make an impact on a bioenergy crop that flourishes on reclaimed mining lands.
Previously living materials, including perennial grasses like Miscanthus x giganteus, produce bioenergy. Ember Morrissey, associate professor of environmental microbiology in the Davis College of Agriculture, Natural Resources and Design, is examining the symbiotic relationship between microbes and this type of tall grass to prepare for climate change and decreasing fossil fuel usage.

Survival of the Best: the Past, Present and Future of Plant Breeding
Yahoo Finance
The carrot on your plate might seem like the most simple thing in the world – a hardy root that has nourished humans, from kings to peasants, for generations. But as humble as it seems, the common carrot – long, orange and crunchy – is actually just one result of a genetic engineering project that has been going on for the last ten thousand years. In the wild, carrots are small, pale and have thin, forked roots with a strong flavor. Only centuries of selective breeding for desirable traits has given us the carrot we see today.

Smart News a New Candidate for Oldest Tree in the World is Discovered in Chile
From Smithsonian Magazine
Roughly 5,400 years ago, a tiny seed sprouted from the forest floor in central Chile. As it survived fires and logging, the Patagonian cypress grew to become one of the largest trees inside Alerce Costero National Park, eventually ballooning to more than 13 feet in diameter.
Now, a researcher believes the tree — known as Alerce Milenario or Gran Abuelo, the “great-grandfather” tree — is likely the oldest in the world, reports Science’s Gabriel Popkin.

The spotlight is on Vassiliki A. Michalopoulou, Glykeria Mermigka, Konstantinos Kotsaridis, Andriani Mentzelopoulou, Patrick H. N. Celie, Panagiotis N. Moschou, Jonathan D. G. Jones, and Panagiotis F. Sarris. Their research reveals that XopP, a core bacterial effector of Xanthomonas campestris, manipulates the plant exocyst complex bypassing several host defense responses.
The spotlight is on Wun S. Chao, Xuehui Li, David P. Horvath, and James V. Anderson. They have identified 24 candidate genes in the 14 loci associated with the chlorophyll fluorescence ratings used to measure freezing tolerance and found that most markers had significant association with Fv/Fm and Fv/Fo readings at 7 days after freezing treatment. Thus, the candidate genes linked to those markers may play a general role in protecting photosynthetic machinery.
In the third of the Plant Physiology Editor's Profiles series, Assistant Features Editor Guada Fernández-Milmanda interviews Monitoring Editor Ronald Pierik. Ronald talks about his long-standing interest in plant photobiology, particularly shade avoidance responses. He and Guada discuss the roles of editors and reviewers, their favorite photobiology papers, and the satisfaction that comes from mentoring. As a bonus, the interview includes a link to the Pierik lab “photobiology playlist”.
