Plants tend to flower earlier if placed under stress conditions. Those stress factors include drought, high salinity, low temperature, high- or low-intensity light, and ultraviolet light. This phenomenon has been called stress-induced flowering. Stress-induced plant flowering might be helpful for species preservation. Thus, stress-induced flowering might have biological significance and should be considered as important as other plant flowering control strategy. Here, history of stress-induced flowering, metabolic regulation and molecular regulation mechanisms in plants were reviewed. Potential perspective was discussed.

Chronic stress exposure has been widely recognized as a significant contributor to numerous central nervous system (CNS) disorders, leading to debilitating behavioral changes such as anxiety, depression, and cognitive impairments. The prolonged activation of the hypothalamic-pituitary-adrenal (HPA) axis during chronic stress disrupts the neuroendocrine balance and has detrimental effects on neuronal function and survival.

Article Synopsis
- Stress in plants triggers changes in their traits, but it's unclear if these changes are direct responses to stress or influenced by shifts in soil microbial communities.
- In an experiment involving plants grown under different stress conditions, it was found that only live microbial communities led to delayed flowering in stressed plants, a response that proved to be maladaptive.
- The study indicates that microbes not only influence plant trait expression but also disrupt genetic correlations important for plant evolution, suggesting a significant role of soil microbes in shaping plant plasticity and evolution under stress.

NAC (NAM, ATAF, and CUC) transcription factors are essential in regulating plant stress response and senescence, with their functions being modulated by alternative splicing. The molecular mechanisms of stress-induced premature flowering and drought tolerance in (moso bamboo) are not yet fully understood. In this study, a novel NAC variant derived from , named , was isolated.

Jasmonates are a family of oxylipin phytohormones regulating plant development and growth and mediating "defense versus growth" responses. The upstream JA biosynthetic precursor cis-(+)-12-oxo-phytodienoic acid (cis-OPDA) acts independently of CORONATIVE INSENSITIVE 1-mediated JA signaling in several stress-induced and developmental processes. However, its perception and metabolism are only partially understood.

In vivo, microspores in the anthers follow the gametophytic development pathway, culminating in the formation of pollen grains. Conversely, in vitro, under stress treatments, microspores can be reprogrammed into totipotent cells, initiating an embryogenic pathway that produces haploid and double-haploid embryos, which are important biotechnological tools in plant breeding. There is growing evidence that epigenetic reprogramming occurs during microspore embryogenesis through DNA methylation, but less is known about the role of histone modifications.
