About this Research Topic
Plant organ maturation and senescence is a terminal and irreversible developmental process that transforms organs from nutrient assimilation to quality formation or nutrient remobilization, which is essential for horticultural plant value. In the last two decades, significant breakthroughs in revealing the molecular mechanisms underlying organ maturation and senescence have benefited from the identification and functional assays of key genes in some model plants, such as fruit ripening genes in tomato, flower senescence-associated genes (SAGs) in petunia and leaf SAGs in Arabidopsis. However, even though some of the mechanisms of maturation and senescence have been dissected in model plants, these mechanisms are not always universal and also limited in several key genes regulation, and studies in this field are still slow and challenging in other horticultural plants.
The initiation and progression of horticultural plant organ maturation and senescence are regulated by endogenous and environmental cues. This process involves highly complex and ordered genetic programs closely coordinated by multi-dimensional regulation, including chromatin states, (post-) transcriptional regulation, and (post-) translational regulation. For such complex regulation, we found mechanistic approaches pay so much attention to the details, and often miss the big picture. Therefore, it is important to fully understand the mechanism of plant organ maturation and senescence from a systems perspective.
In this Research Topic, we seek to gather a broad range of studies on genetic, epigenetic, transcriptomic, and metabolomic associated with horticultural plant organ maturation and senescence. We particularly welcome and encourage authors to submit manuscripts about the following subtopics:
- Study of all the elements in a biological system and their relationships related to horticultural plant maturation and senescence.
- Comparative transcriptomic/metabolomic studies and key gene functional analysis related to horticultural plant maturation and senescence.
- Epigenetic regulation, such as chromatin accessibility, DNA methylation, histone modification, non-coding RNA regulation related to horticultural plant maturation, and senescence.
- QTL/GWAS related to horticultural plant maturation and senescence.
- Evolutionary comparison and interpretation of maturation and senescence in multiple species.
