A Transcriptional Module Regulates Embryo and Suspensor Development
Research, The Plant Cell, The Plant Cell: In a NutshellRadoeva et al. investigate a transcription module that controls aspects of embryogenesis in plants. Plant Cell https://doi.org/10.1105/tpc.18.00518.
Background: After the start of embryo development in plants, which is marked by fertilization of the egg cell, the resulting zygote divides asymmetrically…
Members of the Arabidopsis FORKED1-LIKE gene family act to localize PIN1 in developing veins (J Exp Bot.)
Plant Science Research WeeklyVascular system is one of the adaptive features for terrestrial plants. Polar localization of PIN1 is essential for creating directional auxin flow, resulting in vein pattern formation. Mariyamma et al. propose that FORKED1 (FKD1) and its homologues control the PIN1 polar localization. The team identified…
The auxin-regulated CrRLK1L kinase ERULUS controls cell wall composition during root hair tip growth ($) (Curr Biol)
Plant Science Research WeeklyRoot hair outgrowth requires the plant hormone auxin and polarized tip growth and cell wall deposition. Schoenaers et al. showed that the plasma membrane-localized receptor-like kinase ERULUS (ERU) regulates tip growth in root hairs. ERU is regulated by auxin via ARF7 and ARF19 transcription factors,…
