Nucleolar dominance arises in Spartina homoploid hybrids and persists after allopolyploidization

The Plant Journal, Volume 125, Issue 5, March 2026.
Significance Statement Evolution of nucleolar dominance in Spartina anglica since its origin c. 150 years ago. mC, cytosine methylation; NOR, nucleolar organizer regions. rDNA resides within the NORs. Spartina anglica C.E. Hubbard presents an iconic allopolyploid species that formed only 150 years ago, spreading worldwide since then.

Exploring the Relationship between Stellar Mass, Metallicity, and Star Formation Rate at z ∼ 2.3 in KBSS-MOSFIRE

The Astrophysical Journal
The metal enrichment of a galaxy is determined by the cycle of baryons in outflows, inflows, and star formation. The relative contribution and timescale of each process sets the relationship between stellar mass, metallicity, and the star formation rate (
