Apple Hexokinase Mediates Response to Salinity Stress
Plant Physiology, Plant Physiology: On The InsideAbiotic stresses such as drought, salinity, low temperature, and flooding usually lead to sugar accumulation. It has been reported that the accumulation of Glc, Suc, and Fru under high salinity plays an important role in carbon storage, osmotic regulation, and homeostasis, as well as scavenging of free…
Brassinosteroids and Hydrotropism
Plant Physiology, Plant Physiology: On The InsideSoil water availability is a major constraint for crop growth throughout the world. Hydrotropism, the bending of roots in response to moisture gradients, enables plants to take better advantage of available soil water. In contrast to gravitropism and phototropism which have been studied extensively,…
Transcriptomics of deepwater rice (Plant Physiol)
Plant Science Research WeeklyFor most plants, becoming submerged under water can be lethal due to a restriction in gas exchange. One strategy for submergence tolerance is called an escape strategy, such as that employed by deepwater rice; the plant elongates rapidly to raise its leaves above the water level. Minami et al. used transcriptomics…
Chloroplast signaling gates thermotolerance in Arabidopsis (Cell Reports)
Plant Science Research WeeklyPlants are able to sense and respond to temperature changes in their environment. However, the mechanism by which high temperature is sensed and then relayed to affect the expression of heat shock transcription factors (HSFs) is unclear. Dickinson et al. demonstrated that Arabidopsis plants show…
Combining Forces for Hypocotyl Elongation: Histone Modifications, GA, and the Circadian Clock
Research, The Plant Cell, The Plant Cell: In a NutshellZheng et al. discover proteins that mediate interactions between gibberellins and the circadian clock https://doi.org/10.1105/tpc.17.00830
