Unraveling Ammonium Transporter-Mediated Nitrogen Transfer in Arbuscular Mycorrhizal Symbiosis
Jing Hui et al. identified ZmAMT3;1 as a mycorrhiza-specific ammonium transporter that transfers ammonium from fungi to plants across the plant–fungus interface and enhances nitrogen acquisition in maize. Plant Cell https://doi.org/10.1093/plcell/koac225

Unraveling cold tolerance in maize
Li et al. discover a cold-tolerance allele that was not selected during maize domestication.
Background: Cold stress is an important environmental factor that limits plant growth, development, and geographical distribution. Maize originated in Mexico and is sensitive to low temperatures. Cold stress…

How does ENB1 contribute to formation of a persistent endosperm in maize?
Wang et al. explore cellulose deposition in maize seeds.
Qun Wang and Rentao Song
China Agricultural University, Beijing 100193, China
Background: Plant seeds are mainly classified into two types: one with a persistent endosperm as in cereals, and the other with a transient endosperm as in…

Prediction of gene responses to heat and cold stress in maize
Zhou and colleagues dissect the transcriptional response of maize seedlings to cold and heat stress and explore to what extent gene expression can be predicted from cis-regulatory motifs in promoters by employing machine learning approaches
By Peng Zhou, University of Minnesota
Background: Plants…

The Importance of the DNA Damage Response during Maize Kernel Development
Pedroza-Garcia report that the necessity for DNA damage response kinases under non-stress conditions is higher in maize than in Arabidopsis, indicating that the mechanisms maintaining genome integrity may be more important for vegetative and reproductive development than previously thought. Plant Cell…

URM Plant Scientist Highlights - Thelma Madzima (she/her)
Dr. Thelma Madzima (she/her) is one of very few Black faculty in the USA who are plant molecular biologists. Originally from Zimbabwe, Thelma immigrated to the US at the age of 17 to attend college. She received her B.S. in Plant Science and Plant Biotechnology from Fort Valley State University, a historically…
