Abstract Plant roots integrate environmental signals with development using exquisite spatiotemporal control. This is apparent in the deposition of suberin, an apoplastic diffusion barrier, which regulates flow water, solutes and gases, environmentally plastic. Suberin considered a hallmark endodermal differentiation but absent tomato endodermis. Instead, suberin present exodermis, cell type that model organism Arabidopsis thaliana . Here we demonstrate regulatory network has same parts...
Organismal development is remarkably robust, tolerating stochastic errors to produce consistent, so-called canalized adult phenotypes. The mechanistic underpinnings of developmental robustness are poorly understood, but recent studies implicate certain features genetic networks such as functional redundancy, connectivity, and feedback. Here, we examine the BZR/BEH gene family, whose function contributes embryonic stem in plant Arabidopsis thaliana, test current assumptions on redundancy...
Plant species have evolved myriads of solutions, including complex cell type development and regulation, to adapt dynamic environments. To understand this cellular diversity, we profiled tomato root translatomes. Using xylem differentiation in tomato, examples functional innovation, repurposing, conservation transcription factors are described, relative the model plant Arabidopsis. Repurposing innovation genes further observed within an exodermis regulatory network illustrate its function....
Abstract Population growth and climate change will impact food security potentially exacerbate the environmental toll that agriculture has taken on our planet. These existential concerns demand a passionate, interdisciplinary, diverse community of plant science professionals is trained during 21st century. Furthermore, societal trends question importance expert knowledge highlight need to better communicate value rigorous fundamental scientific exploration. Engaging students general public...
ABSTRACT Multicellular organisms control interactions with their environment through the development of specialized barriers in specific cell types. A conserved barrier plant roots is endodermal Casparian strip (CS). The CS made polymerized lignin and forms a ring-like structure that seals apoplastic space between cells. Most angiosperms also have another root type, exodermis, reported to form barrier. Our understanding exodermal developmental molecular regulation, as well function, limited...
Abstract A key remit of the NSF ‐funded “Arabidopsis Research and Training for 21 st Century” ( ART ‐21) Coordination Network has been to convene a series workshops with community members explore issues concerning research training in plant biology, including role that using Arabidopsis thaliana can play addressing those issues. first workshop focused on needs bioinformatic computational approaches biology was held 2016, recommendations from have published (Friesner et al., Plant Physiology...
Abstract The crucial role of microRNAs in plant development is exceedingly well supported; their importance environmental robustness studied less detail. Here, we describe a novel, environmentally dependent phenotype hypomorphic argonaute1 (ago1) mutants and uncover its mechanistic underpinnings Arabidopsis (Arabidopsis thaliana). AGO1 key player microRNA-mediated gene regulation. We observed transparent lesions on embryonic leaves ago1 mutant seedlings. These increased frequency...
Abstract Argonaute 1 (AGO1), the principal protein component of microRNA-mediated regulation, plays a key role in plant growth and development. AGO1 physically interacts with chaperone HSP90, which buffers cryptic genetic variation plants animals. We sought to determine whether perturbation Arabidopsis thaliana would also reveal variation, if so, AGO1-dependent loci overlap those dependent on HSP90. To address these questions, we introgressed hypomorphic mutant allele into set mapping lines...
SUMMARY Plant roots integrate environmental signals and developmental programs using exquisite spatiotemporal control. This is apparent in the deposition of suberin, an apoplastic diffusion barrier, which regulates entry exit water, solutes gases, environmentally plastic. Suberin considered a hallmark endodermal differentiation, but we find that it absent tomato endodermis during normal development. Instead, suberin present exodermis, cell type model organism Arabidopsis thaliana . Here,...
Abstract Multicellular organisms control environmental interactions through specialized barriers in specific cell types. A conserved barrier plant roots is the endodermal Casparian strip (CS), a ring-like structure made of polymerized lignin that seals apoplastic space. Most angiosperms have another root type, exodermis, reported to form barrier. Our understanding exodermal developmental and molecular regulation function limited as this type absent from Arabidopsis thaliana . We demonstrate...
Cereal crops, such as wheat (Triticum aestivum L.) and rice (Oryza sativa L.), provide a huge proportion of calories to humans compared other cultivated plants.While cultivation improvement cereal crops have been accomplished over thousands years, only recently has the importance roots their microbiome, otherwise known
Abstract Plant species have evolved myriads of solutions to adapt dynamic environments, including complex cell type development and regulation. To understand this diversity, we profiled tomato root translatomes chromatin accessibility. Using xylem differentiation in tomato, relative Arabidopsis, examples functional innovation, repurposing conservation transcription factors are described. Repurposing innovation genes further observed within an exodermis regulatory network illustrate its...
Solanaceous plants, such as potato, tomato, and pepper, form key components of the global food supply.This is especially true for vegetative storage organs which are a source starch vitamin C. Solanum tuberosum, or domesticated falls under category plants known geophytes.Geophytes that organs, tubers, from modified stems stolons (reviewed in Khosa et al., 2021).Geophytes also employ two modes reproduction: sexual reproduction involving flowers through tubers.Switching between these fitness...

Abstract Robustness to both genetic and environmental change is an emergent feature of living systems. Loss phenotypic robustness can be associated with increased penetrance variation. In model organisms in humans, the consequences standing variation buffered by molecular chaperone HSP90. However, it has been argued that HSP90 opposite effect on newly introduced To test buffering new mutations, we vast numbers mutations into wild-type HSP90-reduced plants assessed embryonic lethality early...
ABSTRACT Nitrogen is an essential element for all life processes in plants. As such, plant roots dynamically respond to nitrogen availability below-ground by executing a signaling and transcriptional cascade resulting altered growth, optimized nutrient uptake. The NIN-LIKE PROTEIN 7 (NLP7) transcription factor senses along with its closely related paralog NLP6, partially coordinates these responses. While post-translational regulation of NLP6/7 well established, upstream remains understudied...

This is apparent in suberin deposition which regulates the entry exit of molecules, environmentally plastic. Suberin a hallmark endodermal differentiation, but absent tomato endodermis during normal development. Instead, present exodermis, missing cell type model organism Arabidopsis thaliana. Here, we uncover genes driving exodermal suberization describe its effects on drought...
