Genetics of Maize Inflorescence Architecture
Maize inflorescences have become a model system for functional genomics from agronomic, developmental, and evolutionary viewpoints. The purpose of this research was to gain deeper insights into genetic control of quantitative variation for maize inflorescence architecture. Two biparental …

Genetics of the Arabidopsis Inflorescence Replacement Program
The long-term goal of this project is to characterize the genes responsible for IRP variation in Arabidopsis. The research presented here began by surveying accessions from a collection of geographically diverse Arabidopsis accessions. Five major phenotypic clusters within 85 accessions were …

DEFINING THE FUNCTION OF RICE FLORIGENIC PROTEINS DURING THE REPRODUCTIVE TRANSITION AND INFLORESCENCE DEVELOPMENT
Inflorescence development and its regulation are crucial for rice yield and have been extensively studied. During this process, the inflorescence meristem produces indeterminate branch meristems, followed by determinate spikelet and floret meristems. Extending the indeterminate stage results in …

REGULATING CYTOKININ METABOLISM DURING INFLORESCENCE MERISTEM DEVELOPMENT TO PROMOTE HIGHER RICE PRODUCTIVITY THROUGH CHANGES ON PLANT ARCHITECTURE
… seed size. A transcriptomic analysis of the inflorescence meristem at early developmental stages of the triple mutant osckx3 osckx5 osckx9 revealed a series of uncharacterized differentially expressed genes whose expression patterns might be influenced by cytokinin levels. These genes …

Silene otites (Caryophyllaceae): Attraction of nectar-seeking mosquitoes to inflorescence odours, and temporal variation of flower scent and flower visitors
… monitoring and controlling mosquito populations. Inflorescence odour composition of 63 Silene otites samples of nine populations was determined. There was variability in scent composition among populations and between sexes (Chapter 1). Most populations and samples were dominated by phenyl …

Genetic analysis of Cannabis flowering traits in differential environments
… dioecious, highly heterozygous crop whose female inflorescences underpin the rapidly expanding medicinal and recreational markets. The emerging cannabis industry has necessitated the improvement of inflorescence traits relating to uniformity, quality, and yield under diverse growing conditions. …

Phenology and branching in eight selected species of the genus Cliffortia
To date the peculiarities of the inflorescence structure in the wind-pollinated genus Cliffortia (Rosaceae), has gone unnoticed. In this study stereo microscope examination and sketching of fresh and dried specimens, combined with extensive field observations, were performed on eight species of the …

A Morphological and Phylogenetic Comparative approach to investigating Branching Architecture Evolution in Monocots A Dissertation
The inflorescence is a specialized reproductive branch that dictates flower positions,necessary for effective pollination. Over evolutionary time, changes in branching patterns have led to the evolution of highly diverse inflorescence architecture. This dissertation investigates the developmental …

Quantitative genetic analysis of maize organogenesis
… Understanding the underlying genetics of maize inflorescence serves both purposes. Maize tassel, ear, and leaf organogenesis, although divergent in position on the plant, are hypothesized to share many of the same regulating genomic components. Insights into the genes regulating leaf, ear, and …

Comparison of the effects of reducing light intensity after flag leaf emergence in two wheat cultivars, Triticum Aestivum cv. Karamu and Triticum Aestivum cv. Arawa: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science (Hons.) in the University of Canterbury
It is known from Fisher's (1973) work that the inflorescence development of Norin 10 derivatives is different from that of standard wheat cultivars. Light is a factor that is important in the development of the inflorescence, so the aim of this experiment is to see if Karamu is more affected by a …

The effects of structured variation in nectar standing crop on currency choice and optimal foraging by bumble bees
… confronted with an increasing component of among-inflorescence nectar variation departed inflorescences in manners that diverged increasingly from expectations of the Marginal Value Theorem (MVT). Bees apparently assess inflorescence quality on a per-patch basis, changing their exploitation …

Ecology of flowering and fruiting in Lotus corniculatus L.
… in flowers mainly at the level of the whole inflorescence, rather than altering number of flowers per inflorescence. Within individuals, there are no consistent trade-offs between number of fruit per infructescence, numbers of seeds per fruit and seed weight. Weather patterns only partially …

Development And Application Of Next Generation Sequencing Pipelines In Arabidopsis
… a prerequisite for unlocking genes necessary for inflorescence. In Chapter 3, ChIP-Seq was used to reveal where bZIP transcription factor FD recruits TFL1 to compete for regulation of cell fate within the primordia of inflorescence. In Chapter 4, comparisons of ChIP-Seq experiments from different …

Demographic and environmental determinants of reproductive success in Synthyris bullii, a rare endemic species
… quality. The results of this study show that inflorescence size correlates positively with population size, and that both factors play important roles in determining reproductive output. Chapter 2 examines the response of reproductive morphology to different habitat conditions, and shows that …

Isolation and characterization of the SIAMESE family: a novel class of cell cycle regulators in plants
… SMR2 overexpressing plants fail to produce an inflorescence before senescence. Preliminary evidence implicates the SMRs in the conserved TERMINAL FLOWER1/FLOWERING LOCUS T/SELF-PRUNING signaling system that regulates maintenance of the inflorescence apical meristem. We hypothesize that the SIM …
