Due to the important role of miRNA in regulation of plant gene expression, researchers have focused on the prediction, identification, functional and evolutionary analysis of miRNA. As genome sequencing has been completed in many species, the integration of genomic sequences with evolutionary data of miRNA provides more and more evidence and hypotheses for the origin and evolution of miRNA. However, the evolution of miRNA in plants has not been extensively reviewed. In this article, we reviewed several aspects of the evolution of miRNA in plants, including the origin hypothesis of miRNA, the birth and death of miRNA, and the functional evolution of miRNA, which provides a reference for future research.

CesA proteins response to arsenic stress in rice involves structural and regulatory mechanisms, highlighting the role of BES1/BZR1 transcript levels under arsenate exposure and significant downregulation of BZR1 protein expression. Plants interact with several hazardous metalloids during their life cycle through root and soil connection. One such metalloid, is arsenic and its perilous impact on rice cultivation is a well-known threat.

The axolotl, a legendary creature with the potential to regenerate complex body parts, is positioned as a powerful model organism due to its extraordinary regenerative capabilities. Axolotl can undergo successful regeneration of multiple structures, providing us with the opportunity to understand the factors that exhibit altered activity between regenerative and non-regenerative animals. This comprehensive review will explore the mysteries of axolotl regeneration, from the initial cellular triggers to the intricate signaling cascades that guide this complex process.
