Stenospermocarpy Biological Mechanism That Produces Seedlessness in Some Fruits (Many Table Grapes, Watermelon)

Phytohormones The growth and development of a plant are influenced by: •Gene:c factors •External environmental factors •Chemical hormones inside the plant Secondary messengers 1. Involve in the transfer informaon from sources to targets 2. Amplify the signal produced by the phytohormone Phytohormones Plant hormones are organic compounds that are effec:ve at very low concentraon (1g 20,000 tons-1) They interact with specific target :ssues to cause physiological responses •Growth •Fruit ripening Phytohormones •Hormones s:mulate or inhibit plant growth Major groups of hormones: 1.

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.

Classification by Plant Growth Patterns Monocots vs. Dicots (NB. only applies to flowering plants - angiosperms) Binomial nomenclature e.g., Beetroot = Beta vulgaris Plantae, Angiosperms, Eudicots, Caryophyllales, Amaranthaceae, Betoideae, Beta, Beta vulgaris After morphological characters, scientists used enzymes and proteins to classify plants and hence to determine how related they were via evolution (phylogeny) Present day we use genetic data (DNA, RNA, mDNA, even chloroplast DNA) to produce phylogenetic trees Plant part modifications ● Brassica genus ● ● Roots (swede, turnips) ● Stems (kohl rabi) ● Leaves (cabbages, Brussels Sprouts-buds) ● Flowers (cauliflower, broccoli) ● Seeds (mustards, oil seed rape) Plant hormones / PGR's / phytohormones ● Chemicals present in very low concentrations that promote and influence the growth, development, and differentiation of cells and tissues. ● NB. differences to animal hormones! (no glands, no nervous system, no circulatory system, no specific mode of action) ● Not all plant cells respond to hormones, but those that do are programmed to respond at specific points in their growth cycle ● Five main classes of PGR's ● Abscisic acid (ABA) ● Role in abscission, winter bud dormancy (dormin) ● ABA-mediated signalling also plays an important part in plant responses to environmental stress and plant pathogens ● ABA is also produced in the roots in response to decreased water potential.

Forage Kochia—Uzbekistan's Desert Alfalfa

Forage Kochia—Uzbekistan’s Desert Alfalfa Forage kochia germplasm from Uzbekistan may increase fall and winter grazing and habitat for livestock and wildlife on western rangelands. By B. L. Waldron, R. D. Harrison, A. Rabbimov, T. C. Mukimov, S. Y. Yusupov, and G. Tursvnova Introduction orage kochia is often referred to as the “alfalfa of the desert” by Uzbek sheepherders and is one of their preferred rangeland forages. In the United States, the use of forage kochia for fall and winter livestock Fgrazing is on the increase in the semiarid intermountain area. Past use of this perennial semishrub was mainly by public land agencies for rangeland restoration projects, including soil erosion control, greenstripping, and fire prevention, and to suppress invasive annual weeds, such as cheatgrass and halogeton. In fact, some scientists and range managers feel that forage kochia is the best plant to combat cheatgrass invasion and suppress wildfires on western rangelands.1 Forage kochia has also been used for wildlife habitat and could be a “lifesaver” in maintaining mule deer herds as wild- fire, large sagebrush die-offs, noxious weed invasion, and Figure 1.

The most recent interest, however, stems largely from ranchers and farmers who want to improve the forage research program that included an evaluation of its adap- quantity and quality on private depleted rangelands that tation and germplasm collection trips to Kazakhstan and are traditionally used for wintering livestock (Fig. 1).
