A sufficient nitrogen (N) supply is pivotal for high grain yield and desired grain protein content in wheat (Triticum aestivum L.). Elucidation of physiological and molecular mechanisms underlying nitrogen use efficiency (NUE) will enhance our ability to develop new N-saving varieties in wheat. In this study, we analyzed two soft red winter wheat genotypes, VA08MAS-369 and VA07W-415, with contrasting

Morphological and Molecular Characterization of Pratylenchus dakotaensis n. sp. (Nematoda: Pratylenchidae), a New Root-Lesion Nematode Species on Soybean in North Dakota, USA Plants (IF 2.762) Pub Date : 2021-01-17 Zafar A. Handoo; Guiping Yan; Mihail R. Kantor; Danqiong Huang; Intiaz A. Chowdhury; Addison Plaisance; Gary R. Bauchan; Joseph D. Mowery
Root-lesion nematodes (Pratylenchus spp.) of the genus Pratylenchus Filipjev, 1936, are among the most important nematode pests on soybean (Glycine max (L.) Merr.), along with soybean cyst and root-knot nematodes. In May 2015 and 2016, a total of six soil samples were collected from a soybean field in Walcott, Richland County, ND and submitted to the Mycology and Nematology Genetic Diversity and Biology

Reproductive Output and Insect Behavior in Hybrids and Apomicts from Limonium ovalifolium and L. binervosum Complexes (Plumbaginaceae) in an Open Cross-Pollination Experiment Plants (IF 2.762) Pub Date : 2021-01-17 Sofia I. R. Conceição; Joana Fernandes; Elsa Borges da Silva; Ana D. Caperta
Ex situ plant collections established from seeds of natural populations are key tools for understanding mating systems of intricate taxonomic complexes, as in the Limonium Mill. genus (sea lavenders, Plumbaginaceae). Plants show a polymorphic sexual system associated to flower polymorphisms such as ancillary pollen and stigma and/or heterostyly that prevents self and intramorph mating. The main objectives

Image-Based Methods to Score Fungal Pathogen Symptom Progression and Severity in Excised Arabidopsis Leaves Plants (IF 2.762) Pub Date : 2021-01-15 Mirko Pavicic; Kirk Overmyer; Attiq ur Rehman; Piet Jones; Daniel Jacobson; Kristiina Himanen
Image-based symptom scoring of plant diseases is a powerful tool for associating disease resistance with plant genotypes. Advancements in technology have enabled new imaging and image processing strategies for statistical analysis of time-course experiments. There are several tools available for analyzing symptoms on leaves and fruits of crop plants, but only a few are available for the model plant

Selection and Validation of Reference Genes for Quantitative RT-PCR Analysis in Corylus heterophylla Fisch. × Corylus avellana L. Plants (IF 2.762) Pub Date : 2021-01-15 Sihao Hou; Tiantian Zhao; Dan Yang; Qing Li; Lisong Liang; Guixi Wang; Qinghua Ma
(1) Background: the species of Corylus have sporophytic type of self-incompatibility. Several genes related to recognition reaction between pollen and stigma have been identified in hazelnuts. To better understand the self-incompatibility (SI) response, we screened the suitable reference genes by using quantitative real-time reverse transcription PCR (qRT-PCR) analysis in hazelnut for the first time

Comparative Transcriptome Analysis Provides New Insights into the Molecular Regulatory Mechanism of Adventitious Root Formation in Ramie (Boehmeria nivea L.) Plants (IF 2.762) Pub Date : 2021-01-15 Kunmei Chen; Bing Guo; Chunming Yu; Ping Chen; Jikang Chen; Gang Gao; Xiaofei Wang; Aiguo Zhu
The occurrence of adventitious roots is necessary for the survival of cuttings. In this study, comparative transcriptome analysis between two ramie (Boehmeria nivea L.) varieties with different adventitious root (AR) patterns was performed by mRNA-Seq before rooting (control, CK) and 10 days water-induced adventitious rooting (treatment, T) to reveal the regulatory mechanism of rooting. Characterization

Differentiation of Hedyotis diffusa and Common Adulterants Based on Chloroplast Genome Sequencing and DNA Barcoding Markers Plants (IF 2.762) Pub Date : 2021-01-15 Mavis Hong-Yu Yik; Bobby Lim-Ho Kong; Tin-Yan Siu; David Tai-Wai Lau; Hui Cao; Pang-Chui Shaw
Chinese herbal tea, also known as Liang Cha or cooling beverage, is popular in South China. It is regarded as a quick-fix remedy to relieve minor health problems. Hedyotis diffusa Willd. (colloquially Baihuasheshecao) is a common ingredient of cooling beverages. H. diffusa is also used to treat cancer and bacterial infections. Owing to the high demand for H. diffusa, two common adulterants, Hedyotis

Identification of Tomato Ve1 Homologous Proteins in Flax and Assessment for Race-Specific Resistance in Two Fiber FlaxCultivars against Verticillium dahliae Race 1 Plants (IF 2.762) Pub Date : 2021-01-15 Adrien Blum; Lisa Castel; Isabelle Trinsoutrot-Gattin; Azeddine Driouich; Karine Laval
In the last decade, the soil borne fungal pathogen Verticillium dahliae has had an increasingly strong effect on fiber flax (Linum usitatissimum L.), thus causing important yield losses in Normandy, France. Race-specific resistance against V. dahliae race 1 is determined by tomato Ve1, a leucine-rich repeat (LRR) receptor-like protein (RLP). Furthermore, homologous proteins have been found in various

The Role of Botanical Families in Medicinal Ethnobotany: A Phylogenetic Perspective Plants (IF 2.762) Pub Date : 2021-01-15 Airy Gras; Oriane Hidalgo; Ugo D’Ambrosio; Montse Parada; Teresa Garnatje; Joan Vallès
Studies suggesting that medicinal plants are not chosen at random are becoming more common. The goal of this work is to shed light on the role of botanical families in ethnobotany, depicting in a molecular phylogenetic frame the relationships between families and medicinal uses of vascular plants in several Catalan-speaking territories. The simple quantitative analyses for ailments categories and the

The TOR–Auxin Connection Upstream of Root Hair Growth Plants (IF 2.762) Pub Date : 2021-01-13 Katarzyna Retzer; Wolfram Weckwerth
Plant growth and productivity are orchestrated by a network of signaling cascades involved in balancing responses to perceived environmental changes with resource availability. Vascular plants are divided into the shoot, an aboveground organ where sugar is synthesized, and the underground located root. Continuous growth requires the generation of energy in the form of carbohydrates in the leaves upon

Anti-Aging Potential of Extracts from Washingtonia filifera Seeds Plants (IF 2.762) Pub Date : 2021-01-14 Benedetta Era; Sonia Floris; Valeria Sogos; Clara Porcedda; Alessandra Piras; Rosaria Medda; Antonella Fais; Francesca Pintus
The aim of this study was to test the inhibitory effect of fruit extracts from Washingtonia filifera on skin aging-related enzymes. The pulp extracts did not exert a significant enzyme inhibition while seed extracts from W. filifera exhibit anti-elastase, anti-collagenase, and anti-tyrosinase activities. Tyrosinase was mildly inhibited while a stronger effect was observed with respect to elastase and

Effects of Different Nitrogen Forms and Exogenous Application of Putrescine on Heat Stress of Cauliflower: Photosynthetic Gas Exchange, Mineral Concentration and Lipid Peroxidation Plants (IF 2.762) Pub Date : 2021-01-14 Jacinta Collado-González; María Carmen Piñero; Ginés Otálora; Josefa López-Marín; Francisco M. del Amor
This study examines the effect of the exogenous application of polyamine putrescine together with the application of different ratios of nitrate/ammonium (NO3−/NH4+), on the physiology of cauliflower subjected to heat stress. The 50:50 NO3−/NH4+ ratio was the best ratio against heat stress. As a result of the joint application of these compounds, a higher photosynthetic rate, a higher accumulation
