Waterlogging is a common abiotic stress in both natural and agricultural systems, and it primarily affects plant growth by the slow oxygen diffusion in water. To sustain root function in the hypoxic environment, a key adaptation for waterlogging tolerant plants is the formation of adventitious roots (ARs). We found that cucumber waterlogging tolerant line Zaoer-N seedlings adapt to waterlogging...
Numerous studies deal with composition and molecular processes involved in primary cell wall formation and alteration in Arabidopsis. However, it still remains difficult to assess the relation between physiological properties and mechanical function at the cell wall level. The thin and fragile structure of primary cell walls and their large biological variability, partly related to structural c...
In Arabidopsis thaliana, the circadian clock regulates diurnal and photoperiodic plant growth including the elongation of hypocotyls in a time-of-day-specific and short-day (SD)-specific manner. The clock-controlled PHYTOCHROME-INTERACTING FACTOR 4 (PIF4) encoding a basic helix-loop-helix (bHLH) transcription factor plays crucial roles in this regulation. PIF4 is transcribed precociously at the...
Plant morphogenesis is profoundly influenced by light (a phenomenon known as photomorphogenesis). For example, light inhibits seedling hypocotyl growth via activation of phytochromes and additional photoreceptors. Subsequently, information is transmitted through photoreceptor-linked signal transduction pathways and used (via previously unknown mechanisms) to control hypocotyl growth. Here we sh...
