Bud Initiation

The transition to flowering in plants is the result of the balance of endogenous processes and environmental signals that act through a complex genetic pathway that has been studied extensively in annual plants such as Arabidopsis. Perennial trees are characterised by a juvenile non-flowering phase lasting several years followed by an adult phase in which there is repeated cycling between vegetative and reproductive growth. The genetic control of flowering time is potentially more complex in perennials than in annuals and is less understood. Here, we examine the control of flowering in Eucalyptus globulus subsp. globulus, an important forestry species in temperate parts of the world. The E. globulus subsp. globulus homologues of two important flowering genes FLOWERING LOCUS T (FT) and LEAFY (LFY) were isolated and quantitative RT-PCR was used to measure their expression over a 2-year period. The expression of the homologue of FT in E. globulus subsp. globulus leaves was associated with the annual transition from vegetative to reproductive growth (i.e. flower bud initiation). Expression of the LFY homologue was associated with early flower bud development. In a comparison of FT and LFY expression patterns in two clones each of an early and late anthesis genotype, no association between the expression of these genes and the timing of anthesis was shown. Taken together, this indicates that FT and LFY could form part of the flower initiation pathway in Eucalyptus but do not regulate the observed differences in anthesis time.

Biotic Stresses

Proteins encoded by U-box type ubiquitin ligase (PUB) genes in rice are known to play an important role in plant responses to abiotic and biotic stresses. Functional analysis has revealed a detailed molecular mechanism involving PUB proteins in relation to abiotic and biotic stresses. In this study, characteristics of 77 OsPUB genes in rice were identified. Systematic and comprehensive analyses of the OsPUB gene family were then performed, including analysis of conserved domains, phylogenetic relationships, gene structure, chromosome location, cis-acting elements, and expression patterns. Through transcriptome analysis, we confirmed that 16 OsPUB genes show similar expression patterns in drought stress and blast infection response pathways. Numerous cis-acting elements were found in promoter sequences of 16 OsPUB genes, indicating that the OsPUB genes might be involved in complex regulatory networks to control hormones, stress responses, and cellular development. We performed qRT-PCR on 16 OsPUB genes under drought stress and blast infection to further identify the reliability of transcriptome and cis-element analysis data. It was confirmed that the expression pattern was similar to RNA-sequencing analysis results. The transcription of OsPUB under various stress conditions indicates that the PUB gene might have various functions in the responses of rice to abiotic and biotic stresses. Taken together, these results indicate that the genome-wide analysis of OsPUB genes can provide a solid basis for the functional analysis of U-box E3 ubiquitin ligase genes. The molecular information of the U-box E3 ubiquitin ligase gene family in rice, including gene expression patterns and cis-acting regulatory elements, could be useful for future crop breeding programs by genome editing.

Arabidopsis thaliana Flowering locus T (FT) homologs have been shown to be sufficient to trigger flowering and to regulate flowering time in a wide range of plants. However, such a homologue for the perennial ornamental shrub tree peony has not yet been characterized. In this study, we isolated PsFT, which is a closely related FT homolog from reblooming [Paeonia ×lemoinei ‘High Noon’ (HN)] and nonreblooming [P. ×suffruticosa ‘Luo Yang Hong’ (LYH)] cultivars of tree peonies, and identified its potential role in the regulation of flowering time. The PsFT alleles from the two cultivars encode the same protein, which indicates that the polymorphisms observed in the coding region do not contribute to the distinct flowering phenotypes of HN and LYH. Comparative analyses of the PsFT expression patterns in HN and LYH indicated that PsFT might be associated with reblooming. Transgenic A. thaliana plants ectopically expressing PsFT exhibited a phenotype that included significantly early flowering compared with the wild-type (WT) plants. Taken together, our data provide valuable clues for shortening the juvenile periods and extending the flowering periods of perennial woody plants, such as tree peonies.
