The microRNAs (miRNAs) are a group of small non-coding RNAs found in both plants and animals. Their functions target genes have been identified many plant species. It has shown that miRNAs crucial roles stress responses as much other defence mechanisms. Throughout abiotic stress, regulate their take part signalling pathways. In this study, we evaluated the expression profiles miR156, miR170, mi...

Tapping panel dryness (TPD), a complex physiological syndrome associated with the rubber tree (Hevea brasiliensis Muell. Arg.), causes cessation of latex drainage upon tapping and thus threatens production. Rubber virus 1 (RTV1) is novel positive-sense single-stranded RNA from Betaflexiviridae (genus Capillovirus), which has been established to cause TPD. MicroRNAs (miRNAs) play an important ro...

Understanding of plant adaptation to abiotic stresses has implications in plant breeding, especially in the context of climate change. MicroRNAs (miRNAs) and short interfering RNAs play a crucial role in gene regulation. Here, wheat plants were exposed to one of the following stresses: continuous light, heat or ultraviolet radiations over five consecutive days and leaf tissues from three biolog...

Ambient temperature fluctuates diurnally and seasonally. It profoundly influences the timing of flowering in plants. The floral integrator FLOWERING LOCUS T (FT) mediates ambient temperature signals via the thermosensory pathway in Arabidopsis flowering. microRNA172 (miR172), which promotes flowering by inducing FT, also responds to changes in ambient temperature. However, it is largely unknown...

MicroRNAs (miRNAs) play a pivotal role in plant development. The expression patterns of the miRNA genes significantly influence their regulatory activities. By utilizing small RNA (sRNA) high-throughput sequencing (HTS) data, the miRNA expression patterns were investigated in four organs (flowers, leaves, roots and seedlings) of Arabidopsis. Based on a set of criteria, dozens of organ-specific ...

Drought remains one of the main factors that negatively affect plant growth and development. Caragana korshinskii is widely distributed on the Loess Plateau, China, where it mediates soil and water loss and helps prevent desertification. However, little is known about the stress response mechanisms of C. korshinskii in water-starved environments. MicroRNAs (miRNAs) have been implicated in the r...

Two Arabidopsis thaliana genes (HCC1 and HCC2), resulting from a duplication that took place before the emergence of flowering plants, encode proteins with homology to the SCO proteins involved in copper insertion during cytochrome c oxidase (COX) assembly in other organisms. Heterozygote HCC1 mutant plants produce 25% abnormal seeds with defective embryos arrested at the heart or torpedo stage...

MicroRNA (miRNA)-guided target RNA expression is vital for a wide variety of biological processes in eukaryotes. Currently, miRBase (version 13) lists 142 and 353 miRNAs from Arabidopsis and rice (Oryza sativa), respectively. The integration of miRNAs in diverse biological networks relies upon the confirmation of their RNA targets. In contrast with the well-characterized miRNA targets that are ...

Integrating carbon (C), nitrogen (N), and sulfur (S) metabolism is essential for the growth and development of living organisms. MicroRNAs (miRNAs) play key roles in regulating nutrient metabolism in plants. However, how plant miRNAs mediate crosstalk between different nutrient metabolic pathways is unclear. In this study, deep sequencing of Arabidopsis thaliana small RNAs was used to reveal mi...
