Analysis of taxonomic distinctness and priority conservation areas as a basis for heritage enhancement of floristic diversity: the case of the ‘hotspot’ of the islands of Numidia (North-eastern Algeria)

The identification of priority conservation areas (PCA) plays an important role in biodiversity conservation, but uncertainties create challenges for conservation planning. The objective was to test a method based on 'taxonomic distinctness...

No hay diferencias en la diversidad genética entre arbustos de Cotoneaster franchetii (Rosaceae) de rangos nativos y no nativos.

No hay diferencias en la diversidad genética entre arbustos de Cotoneaster franchetii (Rosaceae) de rangos nativos y no nativos. La diversidad genética de los arbustos de Cotoneaster franchetii es similar entre los rangos de distribución na...

Biosynthesis of rare 20(R)-protopanaxadiol/protopanaxatriol type ginsenosides through Escherichia coli engineered with uridine diphosphate glycosyltransferase genes

Background: Ginsenosides are known as the principal pharmacological active constituents in Panax medicinal plants such as Asian ginseng, American ginseng, and Notoginseng. Some ginsenosides, especially the 20(R) isomers, are found in trace ...

RESPOSTA DIFERENCIAL DAS CULTURAS DE MILHO RR E SOJA RR À EXPOSIÇÃO A GLYPHOSATE E ADUBAÇÃO FOSFATADA

RESUMO A adubação fosfatada pode influenciar a resposta das culturas tolerantes ao glyphosate em razão de a absorção ativa do herbicida ser mediada por carreadores de fosfato. O objetivo desta pesquisa foi analisar características de cresci...

Biodiversidade e considerações biogeográficas das Cyanobacteria de uma área de Manguezal do Estado de Pernambuco, Brasil

Manguezais caracterizam-se por apresentarem amplas variações ambientais (principalmente de salinidade, irradiância e teor de oxigênio) e possuírem substrato relativamente instável, o que exige adaptações específicas dos organismos para habi...

Calyculogygas, nuevo género de Malváceas de Uruguay

Se describe e ilustra el género Calyculogygas nov. junto con la especie C. uruguayensis nov. El género aparentemente está relacionado con Malvastrum (x = 6) pero los 10 cromosomas somáticos fundados en Calyculogygas muestran una relación má...

Functional relation of Actinidia species phytohormonal status with regeneration ability and sex of plants

Endogenous content of phytohormones has been investigated in one-year shoots of different actinidia species, which were introduced in Ukraine. Relationship between phytohormon status of plants and their ability to rooting was established. O...

Lista preliminar de las heliconias de Colombia y cinco especies nuevas

A preliminary check list of the 93 species of Heliconia currently recognized from Colombia is provided. Five new species of subgen. Griggsia (H. arrecta, H. donstonea, H. gigantea, H.terciopete y H. titanum) from that country are also descr...

Predation of Ophiodes fragilis (Squamata: Anguidae) by Cariama cristata (Cariamiformes: Cariamidae)

Reptiles can be on the diet of some bird species, and the glass lizard Ophiodes fragilis seems to be no exception. Although predation events are not easily recorded, in this work we document a new record of predation by C. cristata upon O. ...

mtDNA variation of humpback whales in their wintering grounds of Guerrero, southern Mexican Pacific

Here, we describe variation in mtDNA haplotypes among 22 individual humpback whales off the Guerrero coast in southern Mexico and compare this to other wintering regions in the eastern North Pacific Ocean using published data. After correct...

Plant Growth Regulators Improve Grain Production and Water Use Efficiency of <i>Foeniculum vulgare</i> Mill. under Water Stress

The development of methods increasing plant water use efficiency (WUE) would enhance the ability to grow wild aromatic and medicinally important species. The aim of this research was to determine the effect of plant growth regulators (PGRs)...

Association Mapping of Seed Coat Color Characteristics for Near-Isogenic Lines of Colored Waxy Maize Using Simple Sequence Repeat Markers

Waxy maize is mainly cultivated in South Korea for the production of food and snacks, and colored maize with increased anthocyanin content is used in the production of functional foods and medicinal products. Association mapping analysis (A...

Brassinosteroid-lipid membrane interaction under low and high temperature stress in model systems

Abstract Background In earlier studies [1], we indicated that applying brassinosteroids (BRs) to lipids that had been isolated from plants altered the physicochemical properties of the monolayers. A continuation of these dependencies using ...

Shared but Threatened: The Heritage of Wild Food Plant Gathering among Different Linguistic and Religious Groups in the Ishkoman and Yasin Valleys, North Pakistan

A wild food ethnobotanical field study was conducted in the Ishkoman and Yasin valleys, located in the Hindukush Mountain Range of Gilgit-Baltistan, northern Pakistan. These valleys are inhabited by diverse, often marginalized, linguistic a...

Comparative effects of organic and inorganic fertilizers on photosynthetic pigments, oxidative metabolism, and yield in cotton (Gossypium hirsutum L.) under semi-arid field conditions

Abstract This study was conducted under field conditions at Harran University’s Osmanbey Campus. Experimental plots were established using a randomized block design. Parameters such as chlorophyll a and b, carotenoids, total soluble protein...

A Mitogen-Activated Protein Kinase Gene (MGV1) in Fusarium graminearum Is Required for Female Fertility, Heterokaryon Formation, and Plant Infection

Fusarium graminearum is an important pathogen of small grains and maize in many areas of the world. Infected grains are often contaminated with mycotoxins harmful to humans and animals. During the past decade, F. graminearum has caused seve...

Random T-DNA Mutagenesis Identifies a Cu/Zn Superoxide Dismutase Gene as a Virulence Factor of Sclerotinia sclerotiorum

Agrobacterium-mediated transformation (AMT) was used to identify potential virulence factors in Sclerotinia sclerotiorum. Screening AMT transformants identified two mutants showing significantly reduced virulence. The mutants showed growth ...

Dissecting the genetic basis of fruiting efficiency for genetic enhancement of harvest index, grain number, and yield in wheat

Abstract Background Grain number (GN) is one of the key yield contributing factors in modern wheat (Triticum aestivum) varieties. Fruiting efficiency (FE) is a key trait for increasing GN by making more spike assimilates available to reprod...

Implementation of a Tunnel System for Scaling-Out High-Quality Cassava Planting Material
