A study of photoperiodic inhibition of flower development in Lemna Persusilla 6746
… day plant on Hutner's medium, is induced to flower by a single long night. Resulting flower primordia develop normally in short days but regress in unfavorable photoperiods such as long days or continuous white light. Flower development following a single long night is approximately …

GENOMICS FOR WILD AND MEDICINAL PLANT DIVERSITY STUDIES
… to facilitate research in biodiversity genomics, flower development, and genetic improvement, focusing on two plant species: Salvia pratensis and Althaea officinalis. In one part of the project, a good quality, annotated genome assembly was obtained for Salvia pratensis. The genome was used to …

FUNCTIONAL ANALYSIS OF TRANSCRIPTION FACTORS INVOLVED IN REPRODUCTIVE MERISTEM IDENTITY IN ARABIDOPSIS THALIANA
Flowering is the most important process in a plant’s life as it is the essential step for its reproduction. Flower development starts with a tightly regulated process called the floral transition in which different regulatory pathways, which are regulated by environmental and internal signals, …

Spatio-temporal analysis of florigenic signals in Arabidopsis thaliana, Sinapis alba and Brassica napus
… is one of several parameters controlling flowering time in many plant species. The day length is perceived in leaves, but how the floral signal is transduced to the shoot apex via the phloem to induce flowering remains to be elucidated. This study aimed at the identification of new …

A Role for Late Meristem Identity2 in the Reproductive Development of Arabidopsis
… leaves--to producing reproductive structures--flowers--is a crucial developmental transition that significantly affects the reproductive success of flowering plants. In Arabidopsis thaliana , this transition is in large part controlled by the meristem identity regulator LEAFY (LFY) and the LFY …

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 …

Physiological Responses of Cotton Genotypes to Water-Deficit Stress during Reproductive Development
… and metabolic processes of leaves and flowers of modern cotton cultivars under water-deficit stress during reproductive development is not well elucidated. It was hypothesized that water-deficit stress during squaring and flowering stages would impair stomatal conductance and …

Polarity establishment and signalling mechanisms controlling patterning in Hibiscus Trionum petals
… results in part from coevolution between flowering plants and their pollinators. Distinct cell shapes, cuticular ornamentation, and pigments combine with each other to pattern petals surfaces and these patterns can mediate plant-animal communication. Hibiscus trionum flowers produce a …

Identification of a gene that makes-plants-gigantic-1: characterization of mpg1, a novel mutant of rice
… have been shown to play a role in growth, development, and stress response. The mpg1 plants exhibit a pleiotropic phenotype consisting of greater plant height, larger stems, larger leaves, increased seed yield, delay in flowering, enhanced ratooned growth, and degrees of stress tolerance …

On the molecular pathways supporting the development of structurally coloured cuticle in Hibiscus trionum
… appeared between 250 and 125 million years ago, flowering plants are the most diverse group of plants with about 78% of plant species. The staggering diversity of flowering plants is often correlated with their capacity of adaptation to the diversity of niche space offered by numerous different …

Estudio de nuevas herramientas para el fenotipado vegetal de alta resolución y sus aplicaciones en agricultura
… frente a una línea silenciada en el gen EARLY FLOWERING4 (ELF4) (RNAi:PhELF4). En este estudio se halló un comportamiento nunca antes descrito, al que se le ha puesto el nombre de floración en cadena. Este es un suceso que solo ocurre en las plantas silvestres y que podría actuar como un …
