The activity of the enzyme SENSITIVE TO FREEZING 2 (SFR2) improves cold tolerance of plants and produces trigalactosylsyldiacylglycerol (TGDG), but its role in cold sensitive plants, such as cotton remains unknown. Recently, it was reported that cotton SFR2 produced very little TGDG under normal and cold conditions. Here, we investigate cotton SFR2 activation and TGDG production. Using multiple approaches in the native system and transformation into Arabidopsis thaliana, as well as heterologous yeast expression, we provide evidence that cotton SFR2 activates differently than previously found among other plant species. We conclude with the hypothesis that SFR2 in cotton is not activated in a similar manner regarding acidification or freezing like Arabidopsis and that other regions of SFR2 protein are critical for activation of the enzyme than previously reported.}, number={1}, journal={PLANT SIGNALING & BEHAVIOR}, author={Surber, Samantha M. and Thao, Ngoc Pham Thien and Smith, Cailin N. and Shomo, Zachery D. and Barnes, Allison C. and Roston, Rebecca L.}, year={2024}, month={Dec} }

Phospholipids are important metabolites in plant responses to low-temperature and phosphorus availability and have been suggested to influence flowering time. Here, we combined linkage mapping with genome scans to identifyHigh PhosphatidylCholine 1(HPC1), a gene that encodes a phospholipase A1 enzyme, as a major driver of phospholipid variation in highland maize. Common garden experiments demonstrated strong genotype-by-environment interactions associated with variation atHPC1,with the highlandHPC1allele leading to higher fitness in highlands, possibly by hastening flowering. The highland maizeHPC1variant resulted in impaired function of the encoded protein due to a polymorphism in a highly conserved sequence. A meta-analysis across HPC1 orthologs indicated a strong association between the identity of the amino acid at this position and optimal growth in prokaryotes. Mutagenesis ofHPC1via genome editing validated its role in regulating phospholipid metabolism. Finally, we showed that the highlandHPC1allele entered cultivated maize by introgression from the wild highland teosinteZea maysssp.mexicanaand has been maintained in maize breeding lines from the Northern United States, Canada, and Europe. Thus,HPC1introgressed from teosintemexicanaunderlies a large metabolic QTL that modulates phosphatidylcholine levels and has an adaptive effect at least in part via induction of early flowering time.}, number={27}, journal={PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA}, publisher={Proceedings of the National Academy of Sciences}, author={Barnes, Allison C. and Rodriguez-Zapata, Fausto and Juarez-Nunez, Karla A. and Gates, Daniel J. and Janzen, Garrett M. and Kur, Andi and Wang, Li and Jensen, Sarah E. and Estevez-Palmas, Juan M. and Crow, Taylor M. and et al.}, year={2022}, month={Jul} }

Nine thousand years later, in 2021, Ms. Deb Haaland - a member of the Pueblo of Laguna tribe of New Mexico - wore a dress adorned with a cornstalk when she was sworn in as the Secretary of Interior of the United States of America. This choice of garment highlights the importance of the coevolution of maize and the farmers who, through careful selection over thousands of years, domesticated maize and adapted the physiology and shoot architecture of maize to fit local environments and growth habits. Some traits such as tillering were directly selected on (arches), and others such as tassel size are the by-products (spandrels) of maize evolution. Here, we review current knowledge of the underlying cellular, developmental, physiological, and metabolic processes that were selected by farmers and breeders, which have positioned maize as a top global staple crop.}, journal={CURRENT OPINION IN PLANT BIOLOGY}, publisher={Elsevier BV}, author={Abraham-Juarez, Maria Jazmin and Barnes, Allison C. and Aragon-Raygoza, Alejandro and Tyson, Destiny and Kur, Andi and Strable, Josh and Rellan-Alvarez, Ruben}, year={2021}, month={Dec} }
