WebJul 31, 2015 · Ethylene has been shown to rapidly (within 10 min) affect microtubule orientation in Arabidopsis roots and hypocotyls, likely preventing cell elongation and facilitating radial swelling ( Le et al., 2004, 2005 ). The opposite process has been observed in upper hypocotyl cells when grown in the light ( Le et al., 2005 ). WebAug 30, 2024 · Soil salinity is a serious threat to agriculture, because it compromises biomass production and plant productivity, by negatively affecting the vegetative growth and development of plants.
