Nanoscale movements of cellulose microfibrils in primary cell walls ($)

/
Cell walls are complex mixtures of cellulose microfibrils, proteins and other materials. Their mechanical properties can be measured and modeled, but it is not always simple to translate these measurements to changes at the molecular level. Zhang et al. used atomic force microscopy to provide an unprecedented…

Plant Science Research Weekly: October 18

Guest Editor : Suresh Damodaran I am a postdoctoral research associate in Dr. Lucia Strader’s lab at WUSTL. My primary area of interest is understanding the role of plant hormones in development. I completed my graduate degree in Dr. Sen Subramanian’s lab at SDSTATE.  Twitter: @SureshDamod   Design…

Immunity-growth Trade-off in Plants

Jing et al. reveal how danger-associated peptides inhibit root growth in plants in response to pathogen attack. Plant Cell (2018) https://doi.org/10.1105/tpc.18.00145.   Background: Plants defend themselves against pathogens and pests through an innate immune system that is activated by pathogen-associated…

Fruit Length Regulation in Cucumber

Zhao et al. identify a key regulator of fruit length variation in cucumber. Plant Cell https://doi.org/10.1105/tpc.18.00905 By Jianyu Zhao, China Agricultural University/University of Wisconsin-Madison; Li Jiang, China Agricultural University/Nanjing Agricultural University; Gen Che, China…

Lipids and Auxin Signaling in Plant Salt Responses

Wang et al. highlight the importance of lipid protein interactions in spatiotemporal regulation of auxin signalling. Plant Cell https://doi.org/10.1105/tpc.18.00528 By Peipei Wang and Qun Zhang Background:  Salt stress inhibits plant growth and development, leading to many physiological reactions.…

A Transcriptional Module Regulates Embryo and Suspensor Development

Radoeva 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.)

Vascular 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)

Root 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,…
