Comment une forêt peut-elle émettre plus de CO₂ qu’elle n’en capture ?
Entre 1990 et 2010, la capacité de stockage des forêts a chuté d’environ 30 %. Tour d’horizon, de l’Amazonie à l’Afrique centrale, en passant par des forêts tempérées et boréales.

Beautiful work from Erik Limpens, Ton Bisseling and coll. in @natplants.nature.com. A must read! -> A mobile DELLA controls Medicago truncatula root cortex patterning to host arbuscular mycorrhizal fungi | Nature Plants
A mobile DELLA controls Medicago truncatula root cortex patterning to host arbuscular mycorrhizal fungi
Cell division and specification are crucial for plant development and coping with diverse environmental cues. Most land plants rely on symbiosis with arbuscular mycorrhizal (AM) fungi to cope with soil nutrient limitations by forming arbuscules in root inner cortex cells. What determines the AM susceptibility of these inner cortex cells is currently unknown. Here we show that DELLA transcriptional regulators control the number of inner cortex cells with an AM-susceptible identity at the root stem cell niche of Medicago truncatula in a dose-dependent manner. Genetic analyses suggest that this activity converges with the well-known mobile SHORT-ROOT transcription factor regulating ground tissue development. Furthermore, we show that MtDELLA1 protein moves from the stele/endodermis to the cortex in the mature part of the root to facilitate arbuscule formation. We propose that the formation of a root inner cortex cell identity controlled by mobile DELLA and SHORT-ROOT is a fundamental basis for AM symbiosis.
