Carya illinoinensis (Pecan) Walnut Family (Juglandaceae) Introduction: Pecan only grows native in the western part of Kentucky on the rich soils along the Mississippi and Green rivers. The nut is commercially important and grown on plantations in southern states. Pecan trees can grow very tall. Culture: Pecan grows best on rich, well-drained soils. Like other nut species, it produces a tap root and can be diffi cult to transplant. It can make a handsome land- scape plant where space permits. Botanical Characteristics: Additional information: Pecans are grown commercially in southern Native habitat - Native to the Midwest with states and is the most important nut species native to the its northern limit in Iowa. It grows south into USA. Mexico. In most locations in Kentucky, fruit production is low because the fruits do not mature before winter. Growth habit - The tree produces an open, The National champion trees is Texas and is spreading crown. over 118 feet tall. The Kentucky champion tree is in Trigg County Tree size - Trees commonly reach 100 feet tall and can reach 150 feet tall. and is 100 feet tall. Flower and fruit - Male fl owers are catkins; fe- male fl owers lack petals and are formed in spikes. The fruit is a nut with a four chambered covering. Leaf - Leaves are compound having approximate- ly 12 leafl ets with fi ne teeth along the margin. Fall color is bright yellow. Hardiness - Winter hardy to USDA Zone 5.

Synteny Analysis in Rosids with a Walnut Physical Map Reveals Slow Genome Evolution in Long-Lived Woody Perennials Ming-Cheng Luo1, Frank M
Luo et al. BMC Genomics (2015) 16:707 DOI 10.1186/s12864-015-1906-5 RESEARCH ARTICLE Open Access Synteny analysis in Rosids with a walnut physical map reveals slow genome evolution in long-lived woody perennials Ming-Cheng Luo1, Frank M. You2, Pingchuan Li2, Ji-Rui Wang1,4, Tingting Zhu1, Abhaya M. Dandekar1, Charles A. Leslie1, Mallikarjuna Aradhya3, Patrick E. McGuire1 and Jan Dvorak1* Abstract Background: Mutations often accompany DNA replication. Since there may be fewer cell cycles per year in the germlines of long-lived than short-lived angiosperms, the genomes of long-lived angiosperms may be diverging more slowly than those of short-lived angiosperms. Here we test this hypothesis. Results: We first constructed a genetic map for walnut, a woody perennial. All linkage groups were short, and recombination rates were greatly reduced in the centromeric regions. We then used the genetic map to construct a walnut bacterial artificial chromosome (BAC) clone-based physical map, which contained 15,203 exonic BAC-end sequences, and quantified with it synteny between the walnut genome and genomes of three long-lived woody perennials, Vitis vinifera, Populus trichocarpa,andMalus domestica, and three short-lived herbs, Cucumis sativus, Medicago truncatula, and Fragaria vesca. Each measure of synteny we used showed that the genomes of woody perennials were less diverged from the walnut genome than those of herbs. We also estimated the nucleotide substitution rate at silent codon positions in the walnut lineage. It was one-fifth and one-sixth of published nucleotide substitution rates in the Medicago and Arabidopsis lineages, respectively. We uncovered a whole-genome duplication in the walnut lineage, dated it to the neighborhood of the Cretaceous-Tertiary boundary, and allocated the 16 walnut chromosomes into eight homoeologous pairs.

Wingnut (Juglandaceae)
83 Wingnut (Juglandaceae) as a new generic host for Pityophthorus juglandis (Coleoptera: Curculionidae) and the thousand cankers disease pathogen, Geosmithia morbida (Ascomycota: Hypocreales) Stacy M. Hishinuma, Paul L. Dallara, Mohammad A. Yaghmour, Marcelo M. Zerillo, Corwin M. Parker, Tatiana V. Roubtsova, Tivonne L. Nguyen, Ned A. Tisserat, Richard M. Bostock, Mary L. Flint, Steven J. Seybold1 Abstract—The walnut twig beetle (WTB), Pityophthorus juglandis Blackman (Coleoptera: Curculionidae), vectors a fungus, Geosmithia morbida Kolařík, Freeland, Utley, and Tisserat (Ascomycota: Hypocreales), which colonises and kills the phloem of walnut and butternut trees, Juglans Linnaeus (Juglandaceae). Over the past two decades, this condition, known as thousand cankers disease (TCD), has led to the widespread mortality of Juglans species in the United States of America. Recently the beetle and pathogen were discovered on several Juglans species in northern Italy. Little is known about the extra-generic extent of host acceptability and suitability for the WTB. We report the occurrence of both the WTB and G. morbida in three species of wingnut, Pterocarya fraxinifolia Spach, Pterocarya rhoifolia Siebold and Zuccarini, and Pterocarya stenoptera de Candolle (Juglandaceae) growing in the United States Department of Agriculture-Agricultural Research Service, National Clonal Germplasm Repository collection in northern California (NCGR) and in the Los Angeles County Arboretum and Botanic Garden in southern California, United States of America. In two instances (once in P. stenoptera and once in P. fraxinifolia) teneral (i.e., brood) adult WTB emerged and were collected more than four months after infested branch sections had been collected in the ﬁeld. Koch’s postulates were satisﬁed with an isolate of G.

Juglandaceae (Walnuts)
A start for archaeological Nutters: some edible nuts for archaeologists. By Dorian Q Fuller 24.10.2007 Institute of Archaeology, University College London A “nut” is an edible hard seed, which occurs as a single seed contained in a tough or fibrous pericarp or endocarp. But there are numerous kinds of “nuts” to do not behave according to this anatomical definition (see “nut-alikes” below). Only some major categories of nuts will be treated here, by taxonomic family, selected due to there ethnographic importance or archaeological visibility. Species lists below are not comprehensive but representative of the continental distribution of useful taxa. Nuts are seasonally abundant (autumn/post-monsoon) and readily storable.

Tree Species No. TTS12 Juglans Regia, Family Juglandaceae
Tree Species No. TTS12 Juglans regia, Family Juglandaceae The common walnut is a slow growing medium to large deciduous tree with smooth grey bark that becomes grooved with age. The leaves have a strong scent and open very late, they are between 20 and 30cm long. It is unsuitable for establishment near members of the family Ericaceae, the genus Pontentilla, apples and white pines because the roots of the walnut tree produce a substance that is harmful to these plants. Common names: English walnut, common walnut, carpathian walnut, persian walnut. Distribution: It is native to south-east Asia, south-east Europe, the Himalayas and China, but has been introduced to much of Europe and the United States. Ecology Rainfall: 600-800mm with dry summers. Temperature: Typical of temperate climates. Usually 3-27°C, but temperature as low as -35°F can be tolerated, with only minor injury, when the tree is fully dormant but will tolerate temperatures as low as -10°F when active. Altitude: 400-800m, but may grow at altitudes of 3300m. Soil type: Prefers deep fertile soils that are slightly acidic-neutral (pH of 6-7). Botany Height: 27-30m. Diameter at breast height: The oldest trees can have a girth of between 3.5- 6.5m. Crown: It has a round head and a broad spreading crown. Flowers: The male flowers open late in spring and are bourne in large, drooping 5-10cm catkins. The female catkins are on the same tree but are small, green and upright. The trees are self fertile but the male and female flowers mature at different times so self pollination is rare.

Read Full License Page 1/23 Abstract Background: The walnut family (Juglandaceae) contains commercially important woody trees commonly called walnut, wingnut, pecan and hickory. Phylogenetic relationships in the Juglandaceae are problematic, and their historical diversication has not been claried, in part because of low phylogenetic resolution and/or insucient marker variability. Results: We reconstructed the backbone phylogenetic relationships of Juglandaceae using organelle and nuclear genome data from 27 species. The divergence time of Juglandaceae was estimated to be 78.7 Mya. The major lineages diversied in warm and dry habitats during the mid-Paleocene and early Eocene. The plastid, mitochondrial, and nuclear phylogenetic analyses all revealed three subfamilies, i.e., Juglandoideae, Engelhardioideae, Rhoipteleoideae. Five genera of Juglandoideae were strongly supported. Juglandaceae were estimated to have originated during the late Cretaceous, while Juglandoideae were estimated to have originated during the Paleocene, with evidence for rapid diversication events during several glacial and geological periods. The phylogenetic analyses of organelle sequences and nuclear genome yielded highly supported incongruence positions for J.
