“…In rice, the GO function analysis of differentially expressed genes in blade leaves of SPL4 mutant rice showed that OsSPL4 gene mutations affected protein phosphorylation as well as the binding of iron ions in rice leaves, maintaining the normal plant type of rice . In pea (Pisum sativum L.), PsSPL3a/3c was found to be mainly expressed at the transcriptional level in leaves, hence indicating its possible involvement in leaf phase transition in the pea aging pathway (Vander Schoor et al, 2022). In maize (Zea Mays), SPL4 plays an important role in bract development and meristem establishment (Chuck et al, 2010), while SPL10/14/26 not only regulates the expression of ZmWOX3A and auxin related genes but is also involved in the development of epidermal hair on maize leaves (Kong et al, 2021).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

Chinese bayberry (Myrica rubra) is an important tree in South China, with its fruit being of nutritional and high economic value. In this study, early ripening (ZJ), medium ripening (BQ) and late ripening (DK) varieties were used as test materials. Young leaves of ZJ, BQ and DK in the floral bud morphological differentiation periods were selected for transcriptome sequencing to excavate earliness related genes. A total of 4,538 differentially expressed genes were detected. Based on clustering analysis and comparisons with genes reportedly related to flowering in Arabidopsis thaliana, 25 homologous genes were identified. Of these, one gene named MrSPL4 was determined, with its expression down-regulated in DK but up-regulated in ZJ and BQ. MrSPL4 contained SBP domain and the target site of miR156, and its total and CDS length were 1,664 bp and 555 bp respectively. The overexpression vector of MrSPL4 (35S::35S::MrSPL4-pCambia2301-KY) was further constructed and successfully transfected into tobacco to obtain MrSPL4-positive plants. Based on the results of qRT-PCR, the relative expression of MrSPL4 was up regulated by 3,862.0-5,938.4 times. Additionally, the height of MrSPL4-positive plants was also significantly higher than that of wild-type (WT), with the bud stage occurring 12 days earlier. Altogether, this study identified an important gene -MrSPL4 in Chinese bayberry, which enhanced growth and flowering, which provided important theoretical basis for early-mature breeding of Chinese bayberry.

“…During the juvenile phase, miR156 accumulates in leaves of Arabidopsis thaliana to repress transcription factors of the SQUAMOSA PROMOTER-BINDING PROTEIN-LIKE family (SPL) (Wang, 2014; Wu et al, 2009). In some plants, the transition of vegetative to reproductive phase is accompanied by leaf morphology changes, known as heteroblasty, e.g, Pisum sativum (Vander Schoor et al, 2022), Passiflora edulis (Silva et al, 2019), A. thaliana (Wu et al, 2009) which is also observed in hop (Fric et al, 1991). The identity of leaves is controlled by SPL transcription factors expressed in the shoot apical meristem (SAM) during the early vegetative development (Fouracre and Poethig, 2019).…”

“…The molecular network complex, represented by miR156/172 and FT , was found to be conserved in multiple plant species such as P. edulis (Silva et al, 2019), Dendrobium catenatum (Zheng et al, 2019) and P. sativum (Vander Schoor et al, 2022). Thus, the interplay between age, photoperiod and other molecular pathways influences the miR156-SPLs and miR172-AP2 targeting pairs levels and, under an optimum balance, promotes the FT expression and, consequently, the reproductive transition (Teotia and Tang, 2015).…”

TheHumulus lupulusL. (hops) is traditionally produced in temperate regions, historically attributed to the belief that vernalization was necessary for reproductive transition. Nevertheless, recent studies have revealed the potential for hop plants to flower in tropical and subtropical climates, thereby reshaping cultivation prospects once the developmental disparities are understood and adapted for optimized production. Here, we delved into the hop phenological cycle and the underlying floral regulatory pathways ultimately, seeking to devise strategies to modulate development and enhance production in regions with low latitudes. In contrast to cultivation in temperate regions, hops grown in the subtropical climate of Minas Gerais, Brazil, flower multiple times throughout the year, independently of the season. Hop is a short-day plant, and in Brazil, the photoperiod is consistently inductive due to daylight hours always being below the described threshold (16,5 h of light critical point). We observed that the reproductive transition of hop initiates after a specific number of nodes, 25 to 28, leading us to hypothesize that this process is primarily controlled by endogenous factors. To explore this issue, we first identified in the hop genome families of miRNAs related to reproductive transition, such as the families MIR156 and MIR172, and the PEBP family which includes the FLOWERING LOCUS T (FT). The expression of miR156 decreased along development inversely to miR172 and in synchrony with the upregulation ofHlFT3andHlFT5. These findings strongly support that the reproductive transition in hops under inductive photoperiodic conditions is primarily regulated by endogenous factors related to development and aging throughout the miRNA and FT-associated pathways. Thus, our study shedded light on the intricate molecular mechanisms that underlie hop floral development paving the way for potential advancements in hop production on a global scale.
