Camilla Julie Kørner et al.
Molecular plant-microbe interactions : MPMI, 26(11), 1271-1280 (2013-08-02)
The plant's innate immune system detects potential biotic threats through recognition of microbe-associated molecular patterns (MAMPs) or danger-associated molecular patterns (DAMPs) by pattern recognition receptors (PRR). A central regulator of pattern-triggered immunity (PTI) is the BRI1-associated kinase 1 (BAK1), which
Filip Vandenbussche et al.
The New phytologist, 194(4), 895-909 (2012-03-13)
The vegetative development of plants is strongly dependent on the action of phytohormones. For over a century, the effects of ethylene on plants have been studied, illustrating the profound impact of this gaseous hormone on plant growth, development and stress
Catharina Merchante et al.
Current opinion in plant biology, 16(5), 554-560 (2013-09-10)
The hormone ethylene plays numerous roles in plant development. In the last few years the model of ethylene signaling has evolved from an initially largely linear route to a much more complex pathway with multiple feedback loops. Identification of key
Ethylene removal and fresh product storage: a challenge at the frontiers of chemistry. Toward an approach by photocatalytic oxidation.

Plant biology (Stuttgart, Germany), 15(3), 426-435 (2013-04-12)
Flooding is a widely occurring environmental stress both for natural and cultivated plant species. The primary problems associated with flooding arise due to restricted gas diffusion underwater. This hampers gas exchange needed for the critical processes of photosynthesis and respiration.
