Understanding the classical maize floral development mutant, Polytypic ear1
… (Pt1), affects multiple aspects of inflorescence development, including floral development. Pt1 heterozygote ears and tassels appear to have barren tips with extra floral organs towards the base with extra silks or branch-like protrusions. While the causative gene is unknown, RNA-seq provided …

Genetic regulation of maize floral development - insights from the transcriptome and translatome
Flowers are produced by floral meristems, groups of stem cells that give rise to floral organs. In grasses, including the major cereal crops, flowers (florets) are contained in spikelets, which contain one to many florets, depending on the species. Floral development in plants is regulated by gene …

Molecular characterization of signaling mechanisms in flowering transition in arabidopsis and association mapping of temperature response in floral development within glycine soja
Flowering is a major developmental event that occurs in the life cycle of all angiosperms. It is a finely tuned and highly elaborate set of mechanisms that combines internal and external stimuli to facilitate the transition from vegetative to reproductive growth. The timing of flowering has a …

Genetic studies of phenotypic variants in the woodland strawberry, (Fragaria vesca)
… The observed phenotypes include alterations to floral development, anthocyanin pigmentation and leaf structure. The floral development mutant named green petal (gp) was not associated with the T-DNA insertions present. Based on similar phenotypes induced by mutation of transcription factors …

Floral initiation in <i>Rudbeckia hirta</i>: limited inductive photoperiod, polyamines and cytokinins
This study examined floral initiation in Rudbeckia hirta at the biochemical, cellular, and whole plant levels. Histological and histochemical examination of floral initiation revealed that the pattern of initiation followed closely that described in other species. The primary difference was in the …

Some studies on the genus Acaena
… the reverse is true of A.tenera. Examination of floral development showed no evidence of preformation of flowers in the previous season, initiation occurring simultaneously with snow melt at most sites. The rate of floral development appeared to be linked to site aspect. Seed germination studies …

Development of floral primordia and prediction of flowering in white oak (Quercus alba L.)
… undertaken to gain a better understanding of oak floral development and flower crop variability as they relate to acorn crop variability. The first part traced the ontogeny of staminate and pistillate primordia of white oak (Quercus alba L.). It was found that staminate inflorescences are …

Development And Application Of Next Generation Sequencing Pipelines In Arabidopsis
… the role of specific proteins during floral development. In Chapter 2 analysis of gene expression and chromatin compaction with transcription factor LFY ChIP-seq annotation reveals the role of LFY-binding as a prerequisite for unlocking genes necessary for inflorescence. In Chapter 3, …

A study of salt tolerance in Arabidopsis thaliana and Hordeum vulgare
… from China. Measurements on growth and development, plant water status, tissue ion profiling, photosynthesis rates, and transpiration rates suggested the tolerant line (Zhou 1) enters the reproductive phase of its life cycle approximately one week earlier than the sensitive line (Zhou …

The Evolution of Male Form and Function in Nightshade Flowers
… investigate the diversity of anther form (male floral organs) in the genus Solanum to allow greater understanding of the relationship between anther form and buzz pollination. This project takes a multidisciplinary approach to investigating the anther traits found within the genus Solanum. We …

Female sterility and carpel development in plants
… male organ (stamen) abortion. The ABCE model of floral development provides a basic underlying developmental framework of individual floral whorls across species. However, it stops short of universally explaining the occurrence of selective organ abortion, as in the case of unisexual flowers. …
