Central Cell–Derived Peptides Regulate Early Embryo Patterning in Flowering Plants

Central Cell–Derived Peptides Regulate Early Embryo Patterning in Flowering Plants | Plant and Seed Biology | Scoop.it

Plant embryogenesis initiates with the establishment of an apical-basal axis; however, the molecular mechanisms accompanying this early event remain unclear. Here, we show that a small cysteine-rich peptide family is required for formation of the zygotic basal cell lineage and proembryo patterning in Arabidopsis. EMBRYO SURROUNDING FACTOR 1 (ESF1) peptides accumulate before fertilization in central cell gametes and thereafter in embryo-surrounding endosperm cells. Biochemical and structural analyses revealed cleavage of ESF1 propeptides to form biologically active mature peptides. Further, these peptides act in a non–cell-autonomous manner and synergistically with the receptor-like kinase SHORT SUSPENSOR to promote suspensor elongation through the YODA mitogen-activated protein kinase pathway. Our findings demonstrate that the second female gamete and its sexually derived endosperm regulate early embryonic patterning in flowering plants.

BMC Plant Biology | Abstract | Soybean GmMYB73 promotes lipid accumulation in transgenic plants

Soybean is one of the most important oil crops. The regulatory genes involved in oil accumulation are largely unclear. We initiated studies to identify genes that regulate this process.

The Sainsbury Lab's curator insight, April 28, 2014 3:20 AM

When a plant cell divides, four related proteins control the trafficking of vesicles and ensure that cargo that is normally recycled to the plasma membrane is instead re-routed to the plane of cell division.

Patterning Cues from the Altruistic Sibling

Patterning Cues from the Altruistic Sibling | Plant and Seed Biology | Scoop.it

Double fertilization is a key feature of flowering plants. One sperm cell from the pollen grain fertilizes the egg cell to form the embryo while the other sperm fuses with a second female gamete, called the central cell. The second fertilization event gives rise to the endosperm, long thought to be mainly a nourishing tissue supporting the developing embryo or the germinating seedling (1). In the last issue of Science, Costa and co-workers report that in Arabidopsis thaliana the endosperm also provides crucial signals for the apical-basal patterning process of the embryo (2).

Plant nanobionics approach to augment photosynthesis and biochemical sensing : Nature Materials

Imparting non-native functions to living plants using nanoparticles opens the possibility of creating synthetic materials that can grow and repair themselves using sunlight, water and carbon dioxide. It is now shown that, both in plant extracts and living leaves, carbon nanotubes traverse and localize within the lipid envelope of plant chloroplasts, enhance their photosynthetic activity, and enable near-infrared fluorescence monitoring of nitric oxide.
