Blue is a favored color of many humans. While blue skies and oceans are a common visual experience, this color is less frequently observed in flowers. We first review how blue has been important in human culture, and thus how our perception of blue has likely influenced the way of scientifically evaluating signals produced in nature, including approaches as disparate as Goethe’s Farbenlehre, Linneaus’

Arbuscular Mycorrhizal Fungi Improve Tolerance of the Medicinal Plant Eclipta prostrata (L.) and Induce Major Changes in Polyphenol Profiles Under Salt Stresses Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-16 Nguyen Hong Duc; Au Trung Vo; Imane Haddidi; Hussein Daood; Katalin Posta
Eclipta prostrata (L.) is an important and well-known medicinal plant due to its valuable bioactive compounds. Microorganisms, including arbuscular mycorrhizal fungi (AMF), and salinity could directly impact plant metabolome, thus influencing their secondary metabolites and the efficacy of herbal medicine. In this study, the role of different single AMF species (Funneliformis mosseae, Septoglomus deserticola

How Stress Facilitates Phenotypic Innovation Through Epigenetic Diversity Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-16 Thanvi Srikant; Hajk-Georg Drost
Climate adaptation through phenotypic innovation will become the main challenge for plants during global warming. Plants exhibit a plethora of mechanisms to achieve environmental and developmental plasticity by inducing dynamic alterations of gene regulation and by maximizing natural variation through large population sizes. While successful over long evolutionary time scales, most of these mechanisms

Multiple Small-Effect Alleles of Indica Origin Enhance High Iron-Associated Stress Tolerance in Rice Under Field Conditions in West Africa Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-15 Giovanni Melandri; Mouritala Sikirou; Juan D. Arbelaez; Afeez Shittu; Vimal K. Semwal; Kadougoudiou A. Konaté; Alhassan T. Maji; Steven A. Ngaujah; Inoussa Akintayo; Vishnu Govindaraj; Yuxin Shi; Francisco J. Agosto-Peréz; Anthony J. Greenberg; Gary Atlin; Venuprasad Ramaiah; Susan R. McCouch
Understanding the genetics of field-based tolerance to high iron-associated (HIA) stress in rice can accelerate the development of new varieties with enhanced yield performance in West African lowland ecosystems. To date, few field-based studies have been undertaken to rigorously evaluate rice yield performance under HIA stress conditions. In this study, two NERICA × O. sativa bi-parental rice populations

Effects of Megafol on the Olive Cultivar ‘Arbequina’ Grown Under Severe Saline Stress in Terms of Physiological Traits, Oxidative Stress, Antioxidant Defenses, and Cytosolic Ca2+ Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-14 Daniele Del Buono; Luca Regni; Alberto Marco Del Pino; Maria Luce Bartucca; Carlo Alberto Palmerini; Primo Proietti
Salinity is one of the most impacting abiotic stresses regarding crop productivity and quality. Among the strategies that are attracting attention in the protection of crops from abiotic stresses, there is the use of plant biostimulants. In this study, Megafol (Meg), a commercial plant biostimulant, was tested on olive plants subjected to severe saline stress. Plants treated with salt alone showed

The Ca2+ Sensor Calcineurin B–Like Protein 10 in Plants: Emerging New Crucial Roles for Plant Abiotic Stress Tolerance Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-09 Felix A. Plasencia; Yanira Estrada; Francisco B. Flores; Ana Ortíz-Atienza; Rafael Lozano; Isabel Egea
Ca2+ is a second messenger that mediates plant responses to abiotic stress; Ca2+ signals need to be decoded by Ca2+ sensors that translate the signal into physiological, metabolic, and molecular responses. Recent research regarding the Ca2+ sensor CALCINEURIN B-LIKE PROTEIN 10 (CBL10) has resulted in important advances in understanding the function of this signaling component during abiotic stress

NbWRKY40 Positively Regulates the Response of Nicotiana benthamiana to Tomato Mosaic Virus via Salicylic Acid Signaling Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-01 Yaoyao Jiang; Weiran Zheng; Jing Li; Peng Liu; Kaili Zhong; Peng Jin; Miaoze Xu; Jian Yang; Jianping Chen
WRKY transcription factors play important roles in plants, including responses to stress; however, our understanding of the function of WRKY genes in plant responses to viral infection remains limited. In this study, we investigate the role of NbWRKY40 in Nicotiana benthamiana resistance to tomato mosaic virus (ToMV). NbWRKY40 is significantly downregulated by ToMV infection, and subcellular localization

Modeling Maize Canopy Morphology in Response to Increased Plant Density Front. Plant Sci. (IF 4.402) Pub Date : 2020-11-26 Liang He; Weiwei Sun; Xiang Chen; Liqi Han; Jincai Li; Yuanshan Ma; Youhong Song
Increased plant density markedly affects canopy morphophysiological activities and crop productivity. This study aims to model maize canopy final morphology under increased interplant competition by revising a functional–structural plant model, i.e., ADEL-Maize. A 2-year field experiment was conducted at Mengcheng, Anhui Province, China, in 2016 and 2018. A randomized complete block design of five

Human-Mediated Land Use Change Drives Intraspecific Plant Trait Variation Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-22 Hayley Schroeder; Heather Grab; André Kessler; Katja Poveda
In the Anthropocene, more than three quarters of ice-free land has experienced some form of human-driven habitat modification, with agriculture dominating 40% of the Earth’s surface. This land use change alters the quality, availability, and configuration of habitat resources, affecting the community composition of plants and insects, as well as their interactions with each other. Landscapes dominated

Phenotypic Selection on Flower Color and Floral Display Size by Three Bee Species Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-21 Johanne Brunet; Andrew J. Flick; Austin A. Bauer
Plants exhibit a wide array of floral forms and pollinators can act as agent of selection on floral traits. Two trends have emerged from recent reviews of pollinator-mediated selection in plants. First, pollinator-mediated selection on plant-level attractants such as floral display size is stronger than on flower-level attractant such as flower color. Second, when comparing plant species, distinct

Boron: More Than an Essential Element for Land Plants? Front. Plant Sci. (IF 4.402) Pub Date : 2020-12-18 Greice Leal Pereira; João Antonio Siqueira; Willian Batista-Silva; Flávio Barcellos Cardoso; Adriano Nunes-Nesi; Wagner L. Araújo
Although boron (B) is an element that has long been assumed to be an essential plant micronutrient, this assumption has been recently questioned. Cumulative evidence has demonstrated that the players associated with B uptake and translocation by plant roots include a sophisticated set of proteins used to cope with B levels in the soil solution. Here, we summarize compelling evidence supporting the
