Strigolactones (SLs), a newly discovered class of carotenoid-derived phytohormones, are essential for developmental processes that shape plant architecture and interactions with parasitic weeds and symbiotic arbuscular mycorrhizal fungi. Despite the rapid progress in elucidating the SL biosynthetic pathway, the perception and signalling mechanisms of SL(More)
Pentatricopeptide repeat (PPR) proteins comprise a large family in higher plants and modulate organellar gene expression by participating in various aspects of organellar RNA metabolism. In rice, the family contains 477 members, and the majority of their functions remain unclear. In this study, we isolated and characterized a rice mutant, white stripe leaf(More)
The expression of the β-2 adrenergic receptor (β2AR), one of the stress-inducible receptors, has been reported to be closely correlated with malignant tumors. Prostate cancer is the most common non-cutaneous cancer among males, accompanied with increased castration levels and β2AR activation in patients. However, the role(More)
Mutation of the AM1 gene causes an albino midrib phenotype and enhances tolerance to drought in rice K+ efflux antiporter (KEA) genes encode putative potassium efflux antiporters that are mainly located in plastid-containing organisms, ranging from lower green algae to higher flowering plants. However, little genetic evidence has been provided on the(More)
Flowering time, or heading date, is a critical agronomic trait that determines the cropping season and regional adaptability, and ultimately grain yield in rice. A number of genes involved in photoperiodic flowering have been cloned and their roles in modulating expression of the flowering genes have been characterized to a certain extent. However, much(More)
Five khayanolides (1-O-acetylkhayanolide B 1, khayanolide B 2, khayanolide E 3, 1-O-deacetylkhayanolide E 4, 6-dehydroxylkhayanolide E 5) were isolated from the stem bark of African mahogany Khaya senegalensis (Meliaceae). Their structures and absolute configurations were determined through extensive spectroscopic analyses including MS, NMR, and(More)
Drought is a recurring climatic hazard that reduces the crop yields. To avoid the negative effects of drought on crop production, extensive efforts have been devoted to investigating the complex mechanisms of gene expression and signal transduction during drought stress. Receptor-like kinases (RLKs) play important roles in perceiving extracellular stimuli(More)
Acute myeloid leukemia (AML) is relatively rare in children. Somatic mutations including the single nucleotide polymorphism (SNP) rs16754 in Wilms tumor 1 gene (WT1) and their prognostic relevance in pediatric AML have not been studied in Chinese populations. We analyzed WT1 mutations and rs16754 genotypes in a cohort of 86 patients with de novo pediatric(More)
The self-renewal ability of the leukemia initiating cell-enriched subpopulation is critical for leukemia initiation and maintenance. However, the regulation of leukemia initiating cells for the leukemia progression is poorly understood. In this study, we observed that β-Arrestin1, a multiple-function protein, is elevated in leukemia initiating(More)
