microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha
New Phytologist, EarlyView.The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

New Phytologist, Volume 252, Issue 3, Page 1296-1313, November 2026.The MexMAGIC population mixes native maize varieties from across Mexico to study functional genetic diversity. Summary Defining the genetic basis of local adaptation is a key goal of evolutionary biology and crop improvement. Theory predicts that when selective pressures follow differences in the environment, a cline will be established.

Male Gametophyte Development in Monosomics of Maize
, 1989 The development of male gametophytes in diploid and monosomic-1, -2, -3, -4, -6, -7, -8, -9, and -10 maize plants was characterized. Developmental differences due to nullisomy in the gametophyte were evaluated by comparing the development of haploid and ...
