The near-complete genome assembly of hexaploid wild oat reveals its genome evolution and divergence with cultivated oats.

Avena sterilis, the ancestral species of cultivated oats, is a valuable genetic resource for oat improvement. Here we generated a near-complete 10.99 Gb A.

Ethylene Plays a Dual Role during Infection by of .

infection leads to hypertrophy of host roots and subsequent formation of galls, causing huge economic losses to agricultural producers of plants. Ethylene (ET) has been reported to play a vital role against necrotrophic pathogens in the classic immunity system. More clues suggested that the defense to pathogens in roots may be different from the acrial.

WRKY2 and WRKY10 regulate the circadian expression of during the day through interactions with CCA1/LHY and phyB.

WRKY transcription factors are known mostly for their function in plant defense, abiotic stress responses, senescence, seed germination, and development of the pollen, embryo, and seed. Here, we report the regulatory functions of two WRKY proteins in photomorphogenesis and expression. PIF4 is a critical signaling hub in light, temperature, and hormonal signaling pathways.

SHB1 and CCA1 interaction desensitizes light responses and enhances thermomorphogenesis.

Light and temperature are two important environmental signals to plants. After dawn, photo-activated phytochromes translocate into the nucleus and interact with a family of negative basic helix-loop-helix PIF regulators. Subsequent phosphorylation and degradation of PIFs triggers a series of photomorphogenic responses.

SHORT HYPOCOTYL UNDER BLUE1 or HAIKU2 mixepression alters canola and Arabidopsis seed development.

Canola (Brassica napus) is a widely cultivated species and provides important resources of edible vegetable oil, biodiesel production and animal feed. Seed development in Arabidopsis and canola shares a similar path: an early proliferation of endosperm to form a large seed cavity, followed by a second phase in which the embryo grows to replace the endosperm. In Arabidopsis, the seed reaches almost its final volume before the enlargement of the embryo.

[Effects of different fertilizations on the extractable concentrations of polycyclic aromatic hydrocarbons (PAHs) in aged contaminated soil].

This study was conducted with amaranth as a representative leafy vegetable to elucidate the effects of application of different fertilizers such as inorganic nitrogen and organic fertilizers, which were widely used in agricultural production, on the extractable concentrations of polycyclic aromatic hydrocarbons (PAHs) in aged contaminated soil under a greenhouse incubation experiment. The results show that the extractable concentrations of phenanthrene (Phe), fluoranthene (Flt) and benzo (b) fluoranthene (BbF) decrease significantly in organic fertilizer treatments than those in inorganic nitrogen fertilizer treatments (p < 0.05).
