Clostridioides difficile, an obligate anaerobic bacterium, causes infections leading to prolonged diarrhea. The bacterium produces dormant spores that can withstand an aerobic environment, resulting in easy environmental transfer. Here, we present a convenient sporulation and purification protocol that can be practiced in any lab setting using a portable anaerobic glove bag. This protocol also optimizes existing cell growth methods and presents a detailed trouble shooting guide. This protocol is a modification

Plants use nitrate, ammonium, and organic nitrogen in the soil as nitrogen sources. Since the elevated CO2 environment predicted for the near future will reduce nitrate utilization by C3 species, ammonium is attracting great interest. However, abundant ammonium nutrition impairs growth, i.e., ammonium toxicity, the primary cause of which remains to be determined. Here, we show that ammonium assimilation by GLUTAMINE SYNTHETASE 2 (GLN2) localized in the plastid rather than ammonium accumulation is a primary cause for toxicity, which chall
