Peroxidase Activity As an Indicator of the Iron Deficiency in Banana
IndianJ Plant Physiol., Vol. 5, No.4, (N.S.) pp. 389-391 (Oct.-Dec., 2000) SHORT COMMUNICATION PEROXIDASE ACTIVITY AS AN INDICATOR OF THE IRON DEFICIENCY IN BANANA K. BALAKRISHNAN Department ofCrop Physiology, Horticultural College and Research Institute, Periyakulam - 625 604 Received on 30 Sept., 1998, Revised on 30 Nov., 2000 Effect oflime induced iron chlorosis on enzyme activities was studied in Banana cv. Rasthali. Iron content decreased progressively as the intensity of chlorosis increased. Iron content had positive correlation with catalase, peroxidase, acid phosphatase, polyphenol oxidase and nitrate reductase. Among the enzymes, the activityofperoxidasehad highest positivesignificant(r=997**) associationwith Fecontent. Hence, peroxidase activity could serve as a diagnostic tool to indentify the Fe deficiency/Fe status in Banana. Key words: Banana, chlorosis, iron, peroxidase Among the micrountrients, Fe deficiency is the most ofgreenness in sixmonths old crop. This leafwas used for widespread in ourcountry(Takkar, 1996).

Simple Summary: The genus Lycoris (Amaryllidaceae) comprises about 20 species with high orna- mental and medicinal value. However, germplasm identification is still difficult due to frequent interspecific hybridization and intraspecific morphological variation within this genus. Plastid genome sequencing has been proven to be a useful tool to identify closely related species and is widely used in the field of plant evolution and phylogeny. In the present study, we provided four Citation: Zhang, F.; Wang, N.; chloroplast genomes of Lycoris and retrieved seven published species in the genus for comparative Cheng, G.; Shu, X.; Wang, T.; Zhuang, genomics and phylogenetic analyses.

Complete Chloroplast Genomes Shed Light on Phylogenetic
www.nature.com/scientificreports OPEN Complete chloroplast genomes shed light on phylogenetic relationships, divergence time, and biogeography of Allioideae (Amaryllidaceae) Ju Namgung1,4, Hoang Dang Khoa Do1,2,4, Changkyun Kim1, Hyeok Jae Choi3 & Joo‑Hwan Kim1* Allioideae includes economically important bulb crops such as garlic, onion, leeks, and some ornamental plants in Amaryllidaceae. Here, we reported the complete chloroplast genome (cpDNA) sequences of 17 species of Allioideae, fve of Amaryllidoideae, and one of Agapanthoideae. These cpDNA sequences represent 80 protein‑coding, 30 tRNA, and four rRNA genes, and range from 151,808 to 159,998 bp in length. Loss and pseudogenization of multiple genes (i.e., rps2, infA, and rpl22) appear to have occurred multiple times during the evolution of Alloideae. Additionally, eight mutation hotspots, including rps15-ycf1, rps16-trnQ-UUG, petG-trnW-CCA , psbA upstream, rpl32- trnL-UAG , ycf1, rpl22, matK, and ndhF, were identifed in the studied Allium species. Additionally, we present the frst phylogenomic analysis among the four tribes of Allioideae based on 74 cpDNA coding regions of 21 species of Allioideae, fve species of Amaryllidoideae, one species of Agapanthoideae, and fve species representing selected members of Asparagales. Our molecular phylogenomic results strongly support the monophyly of Allioideae, which is sister to Amaryllioideae. Within Allioideae, Tulbaghieae was sister to Gilliesieae‑Leucocoryneae whereas Allieae was sister to the clade of Tulbaghieae‑ Gilliesieae‑Leucocoryneae. Molecular dating analyses revealed the crown age of Allioideae in the Eocene (40.1 mya) followed by diferentiation of Allieae in the early Miocene (21.3 mya). The split of Gilliesieae from Leucocoryneae was estimated at 16.5 mya. -

Nac. No. 85 Km. 45, Linares, Nuevo León 67700, México 2Plant Physiology, Agricultural College, Professor Jaya Shankar Telangana State Agricultural University, Polasa, Jagtial, Karimnagar, Telangana, India Abstract The present paper make a synthesis of a comparative leaf anatomy including leaf surface, leaf lamina, petiole and venation as well as wood anatomy of 30 woody species of a Tamaulipan Thorn Scrub, Northeastern Mexico. The results showed a large variability in anatomical traits of both leaf and wood anatomy. The variations of these anatomical traits could be effectively used in taxonomic delimitation of the species and adaptation of the species to xeric environments. For example the absence or low frequency of stomata on leaf surface, the presence of long palisade cells, and presence of narrow xylem vessels in the wood could be related to adaptation of the species to drought. Besides the species with dense venation and petiole with thick collenchyma and sclerenchyma and large vascular bundle could be well adapted to xeric environments. It is suggested that a comprehensive consideration of leaf anatomy (leaf surface, lamina, petiole and venation) and wood anatomy should be used as a basis of taxonomy and drought resistance. -
Ferns of the National Forests in Alaska
Ferns of the National Forests in Alaska United States Forest Service R10-RG-182 Department of Alaska Region June 2010 Agriculture Ferns abound in Alaska’s two national forests, the Chugach and the Tongass, which are situated on the southcentral and southeastern coast respectively. These forests contain myriad habitats where ferns thrive. Most showy are the ferns occupying the forest floor of temperate rainforest habitats. However, ferns grow in nearly all non-forested habitats such as beach meadows, wet meadows, alpine meadows, high alpine, and talus slopes. The cool, wet climate highly influenced by the Pacific Ocean creates ideal growing conditions for ferns. In the past, ferns had been loosely grouped with other spore-bearing vascular plants, often called “fern allies.” Recent genetic studies reveal surprises about the relationships among ferns and fern allies. First, ferns appear to be closely related to horsetails; in fact these plants are now grouped as ferns. Second, plants commonly called fern allies (club-mosses, spike-mosses and quillworts) are not at all related to the ferns. General relationships among members of the plant kingdom are shown in the diagram below. Ferns & Horsetails Flowering Plants Conifers Club-mosses, Spike-mosses & Quillworts Mosses & Liverworts Thirty of the fifty-four ferns and horsetails known to grow in Alaska’s national forests are described and pictured in this brochure. They are arranged in the same order as listed in the fern checklist presented on pages 26 and 27. 2 Midrib Blade Pinnule(s) Frond (leaf) Pinna Petiole (leaf stalk) Parts of a fern frond, northern wood fern (p. -

Invasive Plants in Your Backyard!
Invasive Plants In Your Backyard! A Guide to Their Identification and Control new expanded edition Do you know what plants are growing in your yard? Chances are very good that along with your favorite flowers and shrubs, there are non‐native invasives on your property. Non‐native invasives are aggressive exotic plants introduced intentionally for their ornamental value, or accidentally by hitchhiking with people or products. They thrive in our growing conditions, and with no natural enemies have nothing to check their rapid spread. The environmental costs of invasives are great – they crowd out native vegetation and reduce biological diversity, can change how entire ecosystems function, and pose a threat Invasive Morrow’s honeysuckle (S. Leicht, to endangered species. University of Connecticut, bugwood.org) Several organizations in Connecticut are hard at work preventing the spread of invasives, including the Invasive Plant Council, the Invasive Plant Working Group, and the Invasive Plant Atlas of New England. They maintain an official list of invasive and potentially invasive plants, promote invasives eradication, and have helped establish legislation restricting the sale of invasives. Should I be concerned about invasives on my property? Invasive plants can be a major nuisance right in your own backyard. They can kill your favorite trees, show up in your gardens, and overrun your lawn. And, because it can be costly to remove them, they can even lower the value of your property. What’s more, invasive plants can escape to nearby parks, open spaces and natural areas. What should I do if there are invasives on my property? If you find invasive plants on your property they should be removed before the infestation worsens. -
