Transcriptomic and metabolomic reveals silicon enhances adaptation of rice under dry cultivation by improving flavonoid biosynthesis, osmoregulation, and photosynthesis.

Dry cultivation is a new rice crop mode used to alleviate water shortage and develop water-saving agriculture. There is obvious genetic difference compared with drought-tolerant rice. Silicon (Si) plays an important role in plant adaptation to adverse environmental conditions and can significantly improve the drought tolerance and yield of rice.

The complete chloroplast genome of Craib 1914, an economically valuable oil crop.

Craib 1914 is an industrially valuable oil crop from southern China for which little genetic information is available. Here, we found that its complete chloroplast genome is a circular sequence (156,905 bp) with a large single-copy region (LSC) of 67,724 bp, a small single copy region (SSC) of 18,400 bp, and two inverted repeats (IRs). In total, 130 genes were identified, including 86 protein-coding genes, 36 transfer RNAs, and 8 rRNA genes.

Multi-Approach Analysis Reveals Pathways of Cold Tolerance Divergence in .

Understanding the molecular mechanism of the cold response is critical to improve horticultural plant cold tolerance. Here, we documented the physiological, transcriptome, proteome, and hormonal dynamics to cold stress in temperate genotype (Tg) and subtropical genotype (Sg) populations of . Tg suffered minimal osmotic and oxidative damage compared to Sg under the same cold treatment.

Identity and function of a cardiac mitochondrial small conductance Ca-activated K channel splice variant.

We provide evidence for location and function of a small conductance, Ca-activated K (SK) channel isoform 3 (SK3) in mitochondria (m) of guinea pig, rat and human ventricular myocytes. SK agonists protected isolated hearts and mitochondria against ischemia/reperfusion (IR) injury; SK antagonists worsened IR injury. Intravenous infusion of a SK channel agonist/antagonist, respectively, in intact rats was effective in reducing/enhancing regional infarct size induced by coronary artery occlusion.
