Project description:To verify whether phosphorus deficiency can induce sorghum to produce and secrete SLs, we conducted RNA-sequencing (RNA-seq) analyses in sorghum plants grown under phosphorus deficiency conditions; to verify which genes induced by SL treatment, we conducted RNA-sequencing (RNA-seq) analyses in sorghum plants grown under SL treatment.

Project description:The purpose of the present study is to determine the effect of Phosphorus deficiency on gene expression level using microarray analysis to identify genes responsible for root hair development. Phosphorus deficiency induced the formation of root hairs to explore a greater soil volume but molecular mechanisms were unknown. Therefore, microarray experiments were performed using root tips of Brassica carinata cultivars Bale and Bacho, respectively differing in root hair length during Phosphorus deficiency. Experimental design was carried out in nutrient solution in a climate chamber with controlled environmental conditions (20°C, 16h day/8h night cycle, 70% relative humidity) in a randomized design. 25 root tips from 10 day old seedlings grown without Phosphorus of 1cm length were harvested and immediately frozen in liquid nitrogen. Gene expression analyses were performed Results from xy microarrays are summarized in this study. The samples originate from roots of cultivars Bale and Bacho grown in Phosphorus deficient conditions. Microarrays were hybridized with Cy3 and Cy5 labeled cDNA from Bale and Bacho both during Phosphorus deficiency using a dye swap approach

Project description:Phosphorus (P) is an important macronutrient for plant growth that participates in a series of biological processes. Thus, P deficiency is considered as one of the major constraints limiting crop growth and yield. Although stylo (Stylosanthes) is a dominate tropical legume that displays adaptation to low phosphate (Pi) availability in acid soils, its adaptive mechanisms remain largely unknown. In this study, variation in low P stress tolerance was investigated using two stylo cultivars in hydroponics, which revealed that the stylo RY2 cultivar exhibited higher adaptability to Pi starvation than the RY5 cultivar, as reflected by less reduction in dry weight under P deficient condition, and accompanied by higher P concentrations in shoot and root. Furthermore, better root growth performance and higher APase activity were found in leaves and roots of stylo RY2 cultivar compared to RY5. RNA‐seq analysis revealed 8,348 genes that exhibited differentially expressed under P deficient and sufficient conditions in RY2 roots, with many Pi starvation up-regulated genes associated with P metabolic process, protein modification process, transport and other metabolic processes. A group of differentially expressed genes (DEGs) involved in Pi uptake and homeostasis were identified, such as genes encoding Pi transporter (PT), purple acid phosphatase (PAP), multidrug and toxin extrusion (MATE) and aluminum-activated malate transporter (ALMT). Furthermore, a variety of genes related to transcription factors (TFs) and regulators involved in Pi signaling, including genes belonging to the PHOSPHATE STARVATION RESPONSE 1-like (PHR1), WRKY family, the SYG1/PHO81/XPR1 (SPX) domain, bHLH and ARP family, were also regulated by P deficiency in stylo roots. Taken together, this study suggests a complex adaptive response of stylo to P deficiency, contributing to maintain Pi homeostasis.

Project description:Nitrogen (N) and phosphorus (P) are pivotal element for proper plant growth and development. We performed microarray analysis of rice shoot and root after nitrogen deficiency (-N) treatment under phosphorus deficiency (-P) condition to obtain a global view of gene regulations associated with plant response to -N under -P condition.

Project description:In the early stages (30 days) of phosphorus deficiency stress, Epimedium pubescens leaves cope with short-term phosphorus deficiency by increasing the expression of related genes such as carbon metabolism, flavonoid synthesis and hormone signal transduction pathways, producing sufficient energy, scavenging ROS, and adjusting plant morphology. However, with the extension of stress duration to 90 days, the expression of genes related to phosphorus cycling and phosphorus recovery (PHT1-4, PHO1 homolog3, PAP) was upregulated, and transcriptional changes and post-transcriptional regulation (miRNA regulation and protein modification) were enhanced to resist long-term phosphorus deficiency stress. In addition, bHLH, MYB, NAC, WRKY and other families also play an important role in regulating gene expression and coping with phosphorus deficiency stress, especially MYB60 negatively regulates flavonoid synthesis pathway, which is significantly down-regulated in leaves treated with phosphorus deficiency for 30 days, thereby promoting the accumulation of flavonoid compounds in leaves.
