… Pinus taeda, commonly known as loblolly pine, is one of several pines native to the Southeastern United States, from central Texas east to Florida, and north to Delaware and southern New Jersey. Ovulate cone at fertilization phylum coniferophyta. Leaves (needles) in fascicles of 2-3, 12-18 cm long. The needles usually last up to two years before they fall, which gives the species its evergreen character.

As of March 2014, it was the organism having the largest sequenced genome size. Loblolly pine, like most gymnosperms, exhibits high levels of inbreeding depression, especially in the embryonic stage. Phylum : : Coniferophyta Most of the genes are duplicates. The seed cones are green, ripening pale buff-brown, 7–13 cm (2 3⁄4–5 in) in length, 2–3 cm (3⁄4–1 1⁄4 in) broad when closed, opening to 4–6 cm (1 1⁄2–2 1⁄4 in) wide, each scale bearing a sharp spine 3 to 6 mm (0.12 to 0.24 in) long. 10.2305/IUCN.UK.2013-1.RLTS.T42420A2978958.en, Southern Research Station (www.srs.fs.fed.us), "Ten Most Common Trees in the United States", "Sequencing and Assembly of the 22-Gb Loblolly Pine Genome", "Scientists Sequence The Largest Genome To Date", "The axolotl genome and the evolution of key tissue formation regulators", "Masters landmark Ike's Tree suffers major damage, removed", "Decoding the massive genome of loblolly pine using haploid DNA and novel assembly strategies", "Unique Features of the Loblolly Pine (Pinus taeda L.)

It occurs in subgenus Pinus, subsection Australes Loudon. , Loblolly pine is the first among over 100 species of Pinus to have its complete genome sequenced. Its needles are in bundles of three, sometimes twisted, and measure 12–22 cm (4 3⁄4–8 3⁄4 in) long, an intermediate length for southern pines, shorter than those of the longleaf pine or slash pine, but longer than those of the shortleaf pine and spruce pine. , With the advent of wildfire suppression, loblolly pine has become prevalent in some parts of the Deep South that were once dominated by longleaf pine and, especially in northern Florida, slash pine. The first Pinus genome sequence (22 Gbp) was recently reported for Pinus taeda L. (Zimin et al. Southern New Jersey south to central Florida and west to eastern Texas, southeastern Oklahoma, central Arkansas and southern Tennessee. This plant has no children Legal Status. , The "Morris Pine" is located in southeastern Arkansas; it is over 300 years old with a diameter of 142 cm (56 in) and a height of 35.7 m (117 ft).

Pinus taeda Preferred Common Name; loblolly pine Taxonomic Tree; Domain: Eukaryota Kingdom: Plantae Phylum: Spermatophyta Subphylum: Gymnospermae Class: Pinopsida; Uses List; Agroforestry; Boundary, barrier or support; Erosion control or dune stabilization; Revegetation; Windbreak  This was the largest genome assembled until 2018, when the axolotl genome (32Gb) was assembled.  For its timber, the pine species is regarded as the most commercially important tree in the Southeastern U.S., The common name loblolly is given because the pine species is found mostly in lowlands and swampy areas.  A lethal equivalent is the number of deleterious genes per haploid genome whose cumulative effect is the equivalent of one lethal gene.  Conifer genomes are known to be full of repetitive DNA, which make up 82% of the genome in loblolly pine (compared to only 50% in humans). Commonly called "taeda" when used in plantation forestry outside its native range. Pinus taeda. Pages in category "Pinus taeda" This category contains only the following page. These are isolated populations on areas of acidic sandy soil, surrounded by alkaline clays that are poor for pine growth. Ovulate cone at pollination phylum coniferophyta. 97 terms.

Eisenhower, an Augusta National member, hit the tree so many times that at a 1956 club meeting, he proposed that it be cut down. This tree is commercially grown in extensive plantations.. Loblolly Pine seeds (Pinus taeda) Phylum Coniferophyta. The yellowish, resinous wood is prized for lumber, but is also used for wood pulp.  Loblolly pine became the first species with its complete genome sequenced. The opinion of arborists was that the tree could not be saved and should be removed. Other old names, now rarely used, include oldfield pine, due to its status as an early colonizer of abandoned fields; bull pine, due to its size (several other yellow pines are also often so named, especially large isolated specimens); rosemary pine, due to loblolly's distinctive fragrance compared to the other southern pines; and North Carolina pine.  The loblolly pine genome is made up of 22.18 billion base pairs, which is more than seven times that of humans. Exercise 5: Vascular Seed Plants.  As of 2018, assembly of the axolotl genome (32Gb) displaced loblolly pine as the largest assembled genome. Hence, the pine is named as it is generally found in lowlands and swampy areas. Loblolly Pine is an evergreen gymnosperm tree that may grow 60 to 90 feet tall.
