Physiological, Biochemical, And Metabolic Responses Of Abiotic Plant Stress: Salinity And Drought, Kiarash Jamshidi Goharrizi, Michael R. Hamblin, Soraya Karami, Maryam Nazari
Turkish Journal of Botany
The most important types of abiotic stress that affect agricultural crops throughout the world are drought and salinity. These stresses will continue to worsen as the current climate crisis progresses. Plants have evolved a complex set of mechanisms in order to protect themselves from salt and drought. At the macrobiological level, these include alterations in growth rate, water balance, antioxidant defenses, and photosynthesis. Altered metabolites include proline, carbohydrates, glycine betaine, gamma-aminobutyric acid, and polyamines. It is not surprising, thus, that one of the most important research areas of plant biology is the study of plant responses to abiotic stress and …

Ethnobotanical studies focusing on medicinal plant ingredients have always been conducted with the aim of protecting the local ecological knowledge (LEK) of these natural resources. In the globalized world, the rapid loss of biodiversity and cultural and linguistic homogenization have threatened the survival of the planet, together with leading us towards an extinction crisis. In this extreme situation, LEK is also facing serious challenges, especially that of minorities where the pressure is manifold. A number of studies have been carried out among minority groups in recent times, and scientists are attempting to devise solid policy recommendations to celebrate their LEK …
The Involvement Of The Induction Of Anthocyanin Biosynthesis And Transport In Toxic Boron Responsive Regulation In Arabidopsis Thaliana, Ceyhun Kayihan
The Involvement Of The Induction Of Anthocyanin Biosynthesis And Transport In Toxic Boron Responsive Regulation In Arabidopsis Thaliana, Ceyhun Kayihan
Turkish Journal of Botany
Recently, boron (B) has been found to form a complex with anthocyanin, which could be evidence for the B tolerance mechanisms that reduce free B in the leaf tissues of plants. However, the molecular mechanism of anthocyanin biosynthesis and transport has not been satisfactorily elucidated in plants exposed to toxic B. Therefore, the changes in expression levels of some of the phenylpropanoid pathway genes, early and late flavonoid biosynthetic genes, and transcription factors related to anthocyanin biosynthesis and transport were determined in Arabidopsis thaliana under B toxicity. Accordingly, 1 mM boric acid treatment did not cause any significant change in …

Genetic Structure Of Zannichellia L. Populations According To Mountain Barriers In Iranas Revealed By Issr And Srap Markers, Shabnam Abbasi, Saeed Afsharzadeh, Mehri Dinarvand
Turkish Journal of Botany
Zannichellia L. (Potamogetonaceae) is a widespread aquatic genus that is distributed in temperate and subtropical aquatic ecosystems worldwide. Because the biogeographical location of Iran includes mountain ranges and deserts that may cause different habitat types, it was assumed that these Zannichellia populations would be stronger differentiated than observed in Zannichellia from temperate regions. The present study aimed to test whether Z. palustris would demonstrate high levels of genetic differentiation over long distances and across mountain ranges. The genetic structure of the populations of Zannichellia was investigated using inter simple sequence repeats (ISSR) and sequence-related amplified polymorphism (SRAP) as molecular markers. …

Using chemicals known as inhibitors of chromatin remodeling enzymes is a useful approach in understanding the regulation machinery that contributes to the maintenance of or conversion to a pluri- and totipotent states of the cells in multicellular organisms. They can serve as tools to reveal the molecular and cellular mechanisms required for reprogramming. A deeper understanding of reprogramming pathways that drive the cell into a dedifferentiated state might help us enhance plant micropropagation and green biotechnology applications. Chaetocin is one of the histone methyltransferase inhibitors known as key drivers in several cellular processes. It was shown that chaetocin enhanced the …

Soil NO3– affects microbial processes, plant productivity, and environmental N losses. However, the ability to measure soil NO3– is limited by labor-intensive sampling and laboratory analyses. Hence, temporal variation in soil solution NO3– concentration is poorly understood. We evaluated a new potentiometric sensor that continuously measures soil solution NO3– concentration with unprecedented specificity due to a novel membrane that serves as a barrier to interfering anions. First, we compared sensor and salt extraction-based measurements of soil NO3– in well-controlled laboratory conditions. Second, using 60 d of in situ soil NO …

Turkish Journal of Botany
Onosma L., the largest genus of Boraginaceae, is represented by 105 species in Turkey with an endemism rate of 52%. Phytochemical studies indicate that Boraginaceae plants mainly comprise naphthoquinones with a wide range of biological activities including anticancer, antiinflammatory, wound healing, and antioxidant effects. However, few taxa of the genus Onosma have been investigated in detail for their bioactivities. Considering the high rate of endemism and an inadequate number of bioactivity screening studies in literature, we aimed to evaluate the cytotoxic effects and topoisomerase inhibitory activities of some Onosma species growing in southwestern Turkey. Here, we describe a comprehensive cytotoxic …

The identity of an ecological regime is central to modern resilience theory and our understanding of how systems collapse and reorganize following disturbance. However, resilience-based models used in ecosystem management have been criticized for their failure to integrate disturbance outcomes into regime identity. Assessments are needed to understand how well these classifications represent ecosystem responses that occur over management relevant time scales. We tracked post-wildfire forest and grassland dynamics 27 years after wildfire in eastern ponderosa pine savanna. We tested for differences between the assigned identity of a site (forest or grassland) versus classifications based on the site's disturbance history …

Water deficit during the early vegetative growth stages of wheat (Triticum) can limit shoot growth and ultimately impact grain productivity. Introducing diversity in wheat cultivars to enhance the range of phenotypic responses to water limitations during vegetative growth can provide potential avenues for mitigating subsequent yield losses. We tested this hypothesis in an elite durum wheat background by introducing a series of introgressions from a wild emmer (Triticum turgidum ssp. dicoccoides) wheat. Wild emmer populations harbor rich phenotypic diversity for drought-adaptive traits. To determine the effect of these introgressions on vegetative growth under water-limited conditions, we used image-based phenotyping to …

Potential effectiveness of harvest weed seed control (HWSC) systems depends upon seed shatter of the target weed species at crop maturity, enabling its collection and processing at crop harvest. However, seed retention likely is influenced by agroecological and environmental factors. In 2016 and 2017, we assessed seed-shatter phenology in 13 economically important broadleaf weed species in soybean [Glycine max (L.) Merr.] from crop physiological maturity to 4 wk after physiological maturity at multiple sites spread across 14 states in the southern, northern, and mid-Atlantic United States. Greater proportions of seeds were retained by weeds in southern latitudes and shatter rate …

Timing of micronutrient demand and acquisition by maize (Zea Mays L.) is nutrient spe‐ cific and associated with key vegetative and reproductive growth stages. The objective of this study was to determine the fate of foliar‐applied B, Fe, Mn, Zn, and Fe/Zn together, evaluate the effect of foliar micronutrients applied at multiple rates and growth stages on maize grain yield, and deter‐ mine their apparent nutrient recovery efficiency (ANR). Five Randomized Complete Block Design (RCBD) experiments were conducted in 2014 and 2015 at five locations across Nebraska. Total dry matter was collected at 5–6 stages, and separated into leaves, stalk, …

Climate change during the last 40 years has had a serious impact on agriculture and threatens global food and nutritional security. From over half a million plant species, cereals and legumes are the most important for food and nutritional security. Although systematic plant breeding has a relatively short history, con- ventional breeding coupled with advances in technology and crop management strategies has increased crop yields by 56 % globally between 1965− 85, referred to as the Green Revolution. Nevertheless, increased demand for food, feed, fiber, and fuel necessitates the need to break existing yield barriers in many crop plants. In …

Modern plant breeding increasingly relies on genomic information to guide crop im- provement. Although some genes are characterized, additional tools are needed to effectively identify and characterize genes associated with crop traits. To address this need, the mPing element from rice was modified to serve as an activation tag to in- duce expression of nearby genes. Embedding promoter sequences in mPing resulted in a decrease in overall transposition rate; however, this effect was negated by using a hyperactive version of mPing called mmPing20. Transgenic soybean events carrying mPing-based activation tags and the appropriate transposase expression cassettes showed evidence of transposition. …
