Phosphorus, one of the essential elements for plants, is often a limiting nutrient because its low availability and mobility in soils. Significant changes plant morphology biochemical processes are associated with phosphate (Pi) deficiency. However, molecular bases these responses to Pi deficiency not thoroughly elucidated. Therefore, comprehensive survey global gene expression response deprivation was done by using Arabidopsis thaliana whole genome Affymetrix chip (ATH1) quantify...
Abstract Phosphorus (P) remobilization in plants is required for continuous growth and development. The Arabidopsis (Arabidopsis thaliana) inorganic phosphate (Pi) transporter Pht1;5 has been implicated mobilizing stored Pi out of older leaves. In this study, we used a reverse genetics approach to study the role homeostasis. Under low-Pi conditions, loss function (pht1;5-1) resulted reduced P allocation shoots elevated transcript levels several starvation-response genes. Pi-replete pht1;5-1...
Abstract Phosphorus, one of the essential elements for plants, is often a limiting nutrient in soils. Low phosphate (Pi) availability induces sugar-dependent systemic expression genes and modulates root system architecture (RSA). Here, we present differential effects sucrose (Suc) auxin on Pi deficiency responses primary lateral roots Arabidopsis (Arabidopsis thaliana). Inhibition growth loss meristematic activity were evident seedlings grown under with or without Suc. Although...
Phosphate (Pi) availability is a major constraint to plant growth. Consequently, plants have evolved complex adaptations tolerate low Pi conditions. Numerous genes implicated in these been identified, but their chromatin-level regulation has not investigated. The nuclear actin-related protein ARP6 conserved among all eukaryotes and an essential component of the SWR1 chromatin remodeling complex, which regulates transcription via deposition H2A.Z histone variant into chromatin. Here, we...
Many plant roots acquire inorganic phosphate (Pi) from soils directly through the root-soil interface via high-affinity Pi transporters and/or symbiotic associations between cortical cells and arbuscular mycorrhizal fungi. In tomato, three (LePT3, LePT4, LePT5) are up-regulated upon colonization by this study, role of LePT4 in tomato is elucidated molecular physiological characterizations a loss-of-function mutant lept4. absence infection under solution-Pi concentrations (Cp) 0.05 mM 0.5 mM,...
Zinc (Zn) is an essential micronutrient which affects plant growth and development in deficiency can be toxic when present excess. In Arabidopsis thaliana , different families of cation transporters play pivotal roles Zn homeostasis. the study, we evaluated effects its (0 μM; Zn-) excess (75 Zn++) on various morphophysiological molecular traits. Primary root length was reduced Zn- seedlings, whereas there were significant increases number lateral roots under Zn++ conditions, respectively....
Phosphate (Pi) is pivotal for plant growth and development. Pi deficiency triggers local systemically regulated adaptive responses in Arabidopsis thaliana. Inhibition of primary root (PRG) retarded development lateral roots (LRs) are typical deficiency-mediated the system. Expression starvation-responsive (PSR) genes systemically. Here, we report differential influence iron (Fe) availability on systemic sensing by Arabidopsis. P–Fe– condition disrupted sensing, resulting an elongated (PR)....
Abstract Low inorganic phosphate (Pi) availability triggers an array of spatiotemporal adaptive responses in Arabidopsis (Arabidopsis thaliana). There are several reports on the effects Pi deprivation root system that have been attributed to different growth conditions and/or inherent genetic variability. Here we show gelling agents, largely treated as inert components, significantly affect morphophysiological and molecular seedlings deficiencies other nutrients. Inductively coupled...
Abstract Inorganic phosphate (Pi) availability is a major factor determining growth and consequently the productivity of crops. However, it one least available macronutrients due to its high fixation in rhizospheres. To overcome this constraint, plants have developed adaptive responses better acquire, utilize, recycle Pi. Molecular determinants these mechanisms include transcription factors (TFs) that play role transcriptional control, thereby regulating genome-scale networks. In study, we...
Abstract A large number of plants have been tested and exploited in search a green chemistry approach for the fabrication gold or other precious metal nanomaterials. Despite potential plant based methods, very little is known about underlying biochemical reactions genes involved biotransformation mechanism AuCl 4 into nanoparticles (AuNPs). In this research, we thus focused on studying effect Au growth formation by analyses transcriptome, proteome ionome shift Arabidopsis . exposure favored...
Abstract Phosphate (Pi) deficiency is one of the leading causes loss in crop productivity. Plants respond to Pi by increasing acquisition and remobilization involving organic inorganic transporters. Here, we report functional characterization a putative transporter, Glycerol-3-phosphate permease (G3Pp) family, comprising five members (AtG3Pp1 -5) Arabidopsis (Arabidopsis thaliana). AtG3Pp1 AtG3Pp2 showed 24-and 3-fold induction, respectively, roots Pi-deprived seedlings, whereas...
Phosphate (Pi), an essential macronutrient required for growth and development of plants, is often limiting in soils. Pi deficiency modulates the expression starvation-responsive (PSR) genes including transcription factors (TFs). Here, we elucidated role MYB-related TF HYPERSENSITIVITY TO LOW PHOSPHATE-ELICITED PRIMARY ROOT SHORTENING1 HOMOLOG2 (HHO2, At1g68670) regulating acquisition signaling Arabidopsis thaliana HHO2 was specifically significantly induced different tissues response to...
Background and Aims Plant-synthesized sesquiterpenes play a pivotal role in chemotactic interactions with insects. Biosynthesis of functionally diverse is dependent on the availability pool precursor farnesyldiphosphate (FDP). In Arabidopsis thaliana, FPS2, encoding cytosolic synthase, implicated synthesis FDP, but it not known whether enhanced levels FDP have commensurate effect sesquiterpene-mediated defence responses. This study examined transgenic arabidopsis plants generated to...
Pigeonpea is an important legume crop with high protein content. However, it often subjected to various abiotic and biotic stresses. Proteomics a state-of-the-art technique used analyze the profiling of tissue for deciphering molecular entities that could be manipulated developing crops resistant these In this context, comprehensive proteome profile from different vegetative reproductive tissues has become mandatory. Although several extraction protocols diverse plant species have been...
Rice, a staple food crop, is often subjected to drought and salinity stresses thereby limiting its yield potential. Since there cross talk between these abiotic stresses, identification of common and/or overlapping regulatory elements pivotal for generating rice cultivars that showed tolerance towards them. Analysis the gene interaction network (GIN) facilitates identifying role individual genes their interactions with others constitute important molecular determinants in sensing signaling...
Current trends in Machine Learning~(ML) inference on hardware accelerated devices (e.g., GPUs, TPUs) point to alarmingly low utilization. As ML is increasingly time-bounded by tight latency SLOs, increasing data parallelism not an option. The need for better efficiency motivates GPU multiplexing. Furthermore, existing programming abstractions force programmers micro-manage resources early-binding, context-free fashion. We propose a VLIW-inspired Out-of-Order (OoO) Just-in-Time (JIT) compiler...
