Overexpression of AHL proteins enhances root hair production by altering the transcription of RHD6-downstream genes.

AT-HOOK MOTIF NUCLEAR LOCALIZED (AHL) proteins occur in all sequenced plant species. They bind to the AT-rich DNA sequences in chromosomes and regulate gene transcription related to diverse biological processes. However, the molecular mechanism underlying how AHL proteins regulate gene transcription is poorly understood.

THESEUS1 activation by stress: isomerization and peptide perception?

Plant cell-wall perturbation upon environmental stress triggers adaptive cellular responses mediated by plasma membrane-resident sensors. We discuss a recent study by Bacete et al. showing that THESEUS1 (THE1) regulates plant cell adaptive responses to cell-wall disruption and update the working model for THE1 activation.

Morphological, cytological, and molecular evidences for natural hybridization between and (Triticeae: Poaceae).

Some plants with low fertility are morphologically intermediate between and , and were suspected to be natural hybrids between these species. In this study, karyotype analysis showed that natural hybrids and their putative parents were tetraploids (2n = 4x = 28). Meiotic pairing in natural hybrids is more irregular than its putative parents.

Encodes a Cell Wall Mannoprotein Conferring Sensitivity to Salicylic Acid and Virulence to Wheat.

causes head blight (FHB), a devastating disease of wheat. Salicylic acid (SA) is involved in the resistance of wheat to . Cell wall mannoprotein (CWM) is known to trigger defense responses in plants, but its role in the pathogenicity of remains unclear.
