Burke from Home: Plant Edition BURKE FROM HOME PLANT EDITION GRADES: ALL AGES! BEST FOR GRADES 2 –8 WHAT’S INCLUDED: • Learn how plants have adapted to survive in many different environments. • Meet plants with amazing adaptations and solve puzzles about them. • Get to know the plants in your neighborhood and start your own research collection! Can you think of a plant you’ve seen before? How are plants PLANTS ARE LIVING different from other living things? Plants come in many shapes and sizes. Regardless of size, most plants have leaves, a stem, and roots. Plants produce their own energy. Leaves Plants use their leaves to collect energy from the sun to produce their own food. This process is called photosynthesis. Stem PLANTS ARE EVERYWHERE Roots Over 400,000 plant species grow on Earth. Plants can grow in almost every kind of environment you can imagine! Dry desert areas Tall mountain tops Cold ocean waters HOW DO PLANTS DO IT? Like all living things, plants have to do three things to survive: FIND PROTECT REPRODUCE NUTRIENTS THEMSELVES Each plant species has unique traits and characteristics that help them to accomplish these three survival goals. These special qualities are called adaptations. Adaptations help plants to grow and survive in many different types of environments. #BURKEFROMHOME - PLANT EDITION 1 | #BURKEFROMHOME – PLANT EDITION AMAZING ADAPTATIONS What similarities and differences do you notice in the adaptation photos below?

Botanists who study plants have labeled 15 different tropisms, or plant senses! WHAT DOES IT MEAN? The names of these tropisms are based on Greek words. “helio” = sun “hydro” = water Heliotropism: Hydrotropism: Thermotropism: “thermo” = heat Sunflowers rotate to These mangrove roots Rhododendrons curl face the changing sense and grow toward and droop their leaves position of the sun. a water source. to protect them from freezing temperatures.

Furthermore,analytical tools such as game theory, employed to model animal behavior, have also been applied to plants (e.g. 42, 54). There is some question whetherwords used to describe animal behavior, such as the word behavior itself, or foraging, can be properly applied to the activities of plants.

  • History and Epistemology of Plant Behaviour: a Pluralistic View?
    Synthese (2021) 198:3625–3650 https://doi.org/10.1007/s11229-019-02303-9 BIOBEHAVIOUR History and epistemology of plant behaviour: a pluralistic view? Quentin Hiernaux1 Received: 8 June 2018 / Accepted: 24 June 2019 / Published online: 2 July 2019 © Springer Nature B.V. 2019 Abstract Some biologists now argue in favour of a pluralistic approach to plant activities, under- standable both from the classical perspective of physiological mechanisms and that of the biology of behaviour involving choices and decisions in relation to the environ- ment. However, some do not hesitate to go further, such as plant “neurobiologists” or philosophers who today defend an intelligence, a mind or even a plant consciousness in a renewed perspective of these terms. To what extent can we then adhere to pluralism in the study of plant behaviour? How does this pluralism in the study and explanation of plant behaviour fit into, or even build itself up, in a broader history of science? Is it a revolutionary way of rethinking plant behaviour in the twenty-first century or is it an epistemological extension of an older attitude? By proposing a synthesis of the question of plant behaviour by selected elements of the history of botany, the objective is to show that the current plant biology is not unified on the question of behaviour, but that its different tendencies are in fact part of a long botanical tradition with contrasting postures. Two axes that are in fact historically linked will serve as a common thread. 1. Are there several ways of understanding or conceiving plant behaviour within plant sciences and their epistemology? 2.

  • Circadian Regulation of Sunflower Heliotropism, Floral Orientation, and Pollinator Visits

Abstract: Young sunflower plants track the sun from east to west during the day and then reorient during the night to face east in anticipation of dawn. In contrast, mature plants cease movement with their flower heads facing east. We show that circadian regulation of directional growth pathways accounts for both phenomena and leads to increased vegetative biomass and enhanced pollinator visits to flowers. Solar tracking movements are driven by antiphasic patterns of elongation on the east and west sides of the stem. Genes implicated in control of phototropic growth, but not clock genes, are differentially expressed on the opposite sides of solar tracking stems. Thus interactions between environmental response pathways and the internal circadian oscillator coordinate physiological processes with predictable changes in the environment to influence growth and reproduction. One Sentence Summary: Sun-tracking when young, east-facing when mature, warmer sunflowers attract more pollinators. Text+References+Legends Cover Main Text: Most plant species display daily rhythms in organ expansion that are regulated by complex interactions between light and temperature sensing pathways and the circadian clock (1). These rhythms arise in part because the abundance of growth-related factors such as light signaling components and hormones such as gibberellins and auxins are regulated both by the circadian clock and light (2-4).

  • Identifying Molecular Functions of Heliotropic Motor Tissue Through Proteomic Analysis of Soybean Pulvini
    ABSTRACT Title of Document: IDENTIFYING MOLECULAR FUNCTIONS OF HELIOTROPIC MOTOR TISSUE THROUGH PROTEOMIC ANALYSIS OF SOYBEAN PULVINI Hakme Lee, M.S., 2012 Directed By: Professor Joseph Sullivan, Plant Sciences and Landscape Architecture Heliotropic and nyctinastic leaf movement are mediated in soybean through turgor changes in the motor cells of the pulvinus, located at the base of the leaves. While some elements of the signaling pathways have been studied, a broad-scale protein identification has not yet been reported. In my research pulvini proteins were extracted in light- and dark-harvested soybean using the TCA/acetone method and identified by LC-MS/MS. Gene ontology analysis revealed proteins involved in proton transport were enriched in the soybean pulvinus proteome compared to a background soybean proteome. Proteins more highly expressed in the light were mostly stress response proteins, while under-expressed proteins were categorized as energy proteins. Further investigations using more sensitive extraction protocols and a multitude of sample times will build on these initial results to provide a thorough examination of heliotropic mechanisms at the molecular level.
