StHsfB5 Promotes Heat Resistance by Directly Regulating the Expression of Genes in Potato.

With global warming, high temperatures have become a major environmental stress that inhibits plant growth and development. Plants evolve several mechanisms to cope with heat stress accordingly. One of the important mechanisms is the Hsf (heat shock factor)-Hsp (heat shock protein) signaling pathway.

Tissue-level transcriptomic responses to local and distal chilling reveal potential chilling survival mechanisms in maize.

Chilling is a major stress to plants of subtropical and tropical origins including maize (Zea mays L.). To reveal molecular mechanisms underlying chilling tolerance and survival, we investigated transcriptomic responses to chilling stress in differentiated leaves and roots as well as in crowns with meristem activity in maize.

Interactive Effects of Light Quality and Temperature on Arabidopsis Growth and Immunity.

We report here the interactive effects of three light qualities (white, red and blue) and three growth temperatures (16�C, 22�C and 28�C) on rosette growth, hypocotyl elongation and disease resistance in Arabidopsis thaliana. While an increase in temperature promotes hypocotyl elongation irrespective of light quality, the effects of temperature on rosette growth and disease resistance are dependent on light quality. Maximum rosette growth rate under white, red and blue light are observed at 28�C, 16�C and 22�C, respectively.

Dammarane Sapogenins Ameliorates Neurocognitive Functional Impairment Induced by Simulated Long-Duration Spaceflight.

Increasing evidence indicates the occurrence of cognitive impairment in astronauts under spaceflight compound conditions, but the underlying mechanisms and countermeasures need to be explored. In this study, we found that learning and memory abilities were significantly reduced in rats under a simulated long-duration spaceflight environment (SLSE), which includes microgravity, isolation confinement, noises, and altered circadian rhythms. Dammarane sapogenins (DS), alkaline hydrolyzed products of ginsenosides, can enhance cognition function by regulating brain neurotransmitter levels and inhibiting SLSE-induced neuronal injury.

iTRAQ-based quantitative proteomic analysis reveals new metabolic pathways responding to chilling stress in maize seedlings.

Unlabelled: To date, transcriptome profile analysis of maize seedlings in response to cold stress have been well documented; however, changes in protein species abundance of maize seedlings in response to cold stress are still unknown. Herein, leaves from the maize inbred line W9816 (a cold-resistance genotype) were harvested at three-leaf stage, and were used to identify the differential abundance protein species (DAPS) between chilling stress (4°C) and control conditions (25°C). iTRAQ-based quantitative proteomic were used in this study.
