9/7/16 Fruit Pericarp the ovary wall of the ripe fruit, usually has three parts: ● Exocarp the outer layer ● Mesocarp the middle layer ● Endocarp the inner layer Fruit Type Based on Ovary Number Simple fruit formed by the development of a single pistil or ovary ● Fleshy fruits ○ Berry tomato, grape, eggplant ○ Drupe ● Dry fruits ● Ex: apple Aggregate fruit formed by the development of several ovaries produced by one flower ● One flower with many pistils inside ● Ex: blackberry, raspberry Multiple fruit formed by the development of several flowers which fuze during ripening ● Ex: pineapple, fig Plant Classification Taxonomy naming of plants and identification of their relationships ● Binomial nomenclature Carolus Linnaeus responsible for formalizing this method of naming things ● Ex: Strawberries Fragaria ananassa ○ Kingdom Planta ○ Division/Phyla Spermatophyta ○ Class Angiospermae ○ Subclass Dicotyledonae ○ Order Rosales ○ Family ROSACEAE ○ Genus F ragaria (should always be underlined) ○ Species and authority ananassa Duch (should always be underlined) Identification ● Genus species authority Species Botanical Variety ● Ex: Rubis ideaus var.vulgatus (idaeus)Arrhen. (Eur.) Cultivar a species that has been ● LINE ○ Pure line ○ Hybrids ○ Synthetic ○ Seeding mixture ● CLONE ○ Ortet ■ Ramet clone of a clone ■ APROMIXIS reproduction with no fertilization Crucifers Cole Crops Brassica Oleracea ● Capitata ● Brotrysis ● Italica ● Gemmifera ● Acephala ● Gongylodes Scientific System Continued Group ● Ex: Brassica Oleraceae ○ Botrytis group cauliflower ○ Capitata group Cabbage ○ Italica group Broccoli ● Source of reference for naming ○ International Code of Botanical Nomenclature ○ International Code of Nomenclature of Cultivated Plants Taxonomy continued Chemotaxonomy Use chemicals to tells different kinds of plants apart because there are so many that are so similar, sometimes you can’t tell Fingerprinting Another way to tell plants apart when just looking at them won’t do ● RFLP, RAPD Ecological groupings ● Cline ● Ecotype Other Classifications Climate tropical, temperate Usage ● Fruit temperate, tropical ● Vegetable cold, warm ● Nut ● Herb (culinary) ● Flavorings Life Cycle ● Annual plants that live for one year ● Biennial two years ● Perennial forever/until some other factor intervenes 9/9/16 Gene a sequence of DNA (deoxyribonucleic acid) coding for a specific characteristic ● Paired in the chromosomes ● Allelic gene different forms of the same gene ● Replication ○ Bb Heterozygous (small b is recessive and big B is dominant) ○ BB or bb Homozygous ● Punnett square ○ Genotype genetic makeup of a cell that determines specific traits/characteristics ○ Phenotype Physical expression/characteristics of a trait Crossover chromosome sections from one parent crosses over a chromosome from another parent (mutation) Associated with linkage Mutations necessary for evolution Types of genes Major genes ● Qualitative inheritance/single gene is expressed as a phenotype Minor genes ● quantitative/multiple genes work together to be expressed Genome Chromosomes ● Gametic # (1N) mature sexual reproductive cell ● Somatic # (vegetative) (2N) any cell of the plant besides the reproductive ones Polyploids ● Euploids extra of one or more complete sets of chromosomes ● Aneuploids Extra part or whole chromosome Variation in a Population Genetic variation variation in alleles of genes between populations and individuals ● Genetic variation brought on by random mutation Environmental variation species respond to variation in the environment ● Global warming ● Something other than the average norm Heritability how much phenotypic variation in a population is due to genetic variation Plant Breeding Pollination and its implications ● Selfpollination (autogamy) ● Crosspollination (allogamy) ○ Dioecious Male and female flowers are on separate plants ○ Incompatibilities ■ Inbreeding causes less variation, genetic erosion Individuals ● Heterozygous (Aa) ● Homozygous (AA, aa) Population ● Heterogeneous (AA, Aa, aa) ● Homogeneous (AA, AA, AA) Plant Biotechnology ● Plant tissue culture ● Somaclonal variation ● Protoplast fusion ● DNA injection ● DNA analysis ● Transformation Cultivars Cultivar types: ● Line ● Pure line ● Inbred line ● Hybrid ● Synthetic ● Seedling Mixture
