“…Phytohormones, auxin, GA, CTK, ethylene, ABA, and BR, have been proved to act as crucial regulators in plant development and response to various environmental stimulus, including drought, heat, salinity stress, chilling damage, and heavy metal toxicity [ 17 , 57 ]. In control of plant vegetative phase transition and flowering, the regulatory roles of GA, JA, ABA, BR, auxin, ethylene, and CTK have been explored [ 6 , 9 , 12 , 14 , 16 , 17 , 21 , 22 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. Especially, GA and JA have been defined to affect maize vegetative phase change and flowering [ 16 , 18 ].…”

“…DELLA proteins has been proved to link the GA signaling pathway with other phytohormone signaling pathways, such as JA, CTK, ABA, auxin, ethylene, and BR. The JA signaling pathway regulates flowering via controlling floral induction and its crosstalk with the GA signaling pathway [ 37 ]. In maize, GA promotes vegetative phase transition and flowering, but JA acts the opposite role in vegetative phase transition [ 16 , 18 ].…”

“…In the shoot apical meristem, TFL1 (TERMINAL FLOWER 1), a mobile protein ensures the change from vegetative to floral meristems [ 26 ]. Besides GA, other plant hormones also play important roles in the control of flowering time, including ABA, auxin, BR, JA, ethylene, and cytokinin (CTK) [ 6 , 21 , 22 , 34 , 35 , 36 , 37 , 38 , 39 , 40 ]. By contrast, the understanding of the genetic controls of flowering time in maize is limited.…”

The developmental phase changes of maize are closely associated with the life span, environmental adaption, plant height, and disease resistance of the plant and eventually determines the grain yield and quality of maize. A natural mutant, Early Phase Change 1 (ZmEPC1), was selected from the inbred line KN5585. Compared with the wild type plant, the ZmEPC1 mutant exhibits deceased plant stature, accelerated developmental stages, and decreased leaf size. Through the transcriptome sequencing analysis of leaf samples at flowering stage, a total of 4583 differentially expressed genes (DEGs) were screened between the mutant and wild type, including 2914 down-regulated genes and 1669 up-regulated genes. The GO enrichment and KEGG enrichment analysis revealed that the DEGs were mainly involved in hormone response, hormone signal transduction, autophagy, JA response and signal response, photosynthesis, biotic/abiotic stress, and circadian rhythms. The RT-qPCR results revealed that the most tested DEGs display consistent expression alterations between V5 and FT stages. However, several genes showed opposite expression alterations. Strikingly, most of the JA biosynthesis and signaling pathway-related genes displayed diametrically expression alterations between V5 and FT stages. miR156, a key regulator of plant phase transition, exhibited significant down-regulated expression at V5 and FT stages. The expression of two miR156 target genes were both significantly different between mutants and wild type. In conclusion, ZmEPC1 was identified to be mainly involved in the regulation of JA-mediated signaling pathways and hormone response and signaling, which is possible to confer developmental phase change through miR156-SPLs pathway.

“…Fukazawa et al, 2021;Izawa, 2021). In Arabidopsis, gibberellic acid (GA), jasmonic acid (JA), and abscisic acid (ABA) regulate flowering individually or in combination by forming complex networks (Zhai et al, 2015;Shu et al, 2016;Hwang et al, 2019;Bao et al, 2020;L. Zhao et al, 2022).…”

Recent advances and future perspectives in early‐maturing cotton research

Summary Cotton's fundamental requirements for long periods of growth and specific seasonal temperatures limit the global arable areas that can be utilized to cultivate cotton. This constraint can be alleviated by breeding for early‐maturing varieties. By delaying the sowing dates without impacting the boll‐opening time, early‐maturing varieties not only mitigate the yield losses brought on by unfavorable weathers in early spring and late autumn but also help reducing the competition between cotton and other crops for arable land, thereby optimizing the cropping system. This review presents studies and breeding efforts for early‐maturing cotton, which efficiently pyramid early maturity, high‐quality, multiresistance traits, and suitable plant architecture by leveraging pleiotropic genes. Attempts are also made to summarize our current understanding of the molecular mechanisms underlying early maturation, which involves many pathways such as epigenetic, circadian clock, and hormone signaling pathways. Moreover, new avenues and effective measures are proposed for fine‐scale breeding of early‐maturing crops to ensure the healthy development of the agricultural industry.

“…The plant hormone auxin plays a critical role in the patterning of the Asteraceae head, but of course many hormones contribute to flowering time regulation and flower development. Among those, jasmonate is a relatively unexplored player, and Zhao et al (2022) provide a detailed and convincing account of how this hormone plays an important role in the control of flowering time.…”
