“…P depletion and severe P-deficiency in plants causes chlorophyll loss and PS-II system experience photooxidative stress resulting in severe yield limitations (Obersteiner et al 2013;Hern andez and Munn e-Bosch 2015). A proportionate direct relationship between phosphorus and chlorophyll contents in plants had been discussed earlier (Frydenvang et al 2015;Carstensen et al 2018).The study isolate is a phosphate solubilizer. By releasing sufficient soil phosphorus for plant availability they should have helped the treated chilli seedlings build good chlorophyll content.…”

Aim The aim of this study was to screen potential plant growth promoting rhizobacterial (PGPR) actinobacterial isolate with effective inhibition against anthracnose causing fungal pathogen Colletotrichum capsici. Methods and Results In this study, actinobacterias were isolated from rhizosphere soil using dilution plate method and tested for antagonistic potential against pathogenic fungi C. capsici. In primary and secondary screening tests, the actinobacterial isolate BS‐26 displayed high antagonistic activity against the fungal pathogen. Isolate BS‐26 was identified as Streptomyces violaceoruber based on 16S rDNA sequencing. Furthermore, indole acetic acid production, phosphate solubilization and ammonia production have been confirmed in the S. violaceoruber that suggest their potential to be used as PGPR bacteria. A green house experiment showed that application of S. violaceoruber fermentation broth reduced the incidence of the chilli anthracnose and promoted the growth of chilli seedlings with a significant increase in germination %, total plant height, fresh weight and chlorophyll content when compared to controls. Conclusion Streptomyces violaceoruber can be applied as a biofertilizer and biocontrol agent for growing chillies against the attack of fungal pathogen C. capsici. Significance of Impact of the Study The damage caused by anthracnose disease is an issue of concern, affecting negatively the economy involved in chilli cultivation. As chemical methods of control have serious disadvantages, biocontrol approach using beneficial (PGPR) micro‐organisms shall be a better alternative to control crop diseases.

“…Among the correlated genes (with similar expression profile to the query gene) many annotations related to the effects of Pi starvation were found. Some examples are a plasma membrane iron permease, a chlorophyll a–b binding protein of LHCII, a ferric reductase, and a glutaredoxin s17, which are related to functions altered in phosphate deficiency such as iron homeostasis, photosynthesis, redox balance and reactive oxygen species (ROS) (Hirsch et al , ; Bournier et al , ; Hernandez and Munne‐Bosch, ; Carstensen et al , ).…”

PEATmoss (Physcomitrella Expression Atlas Tool): a unified gene expression atlas for the model plant Physcomitrella patens

Physcomitrella patens is a bryophyte model plant that is often used to study plant evolution and development. Its resources are of great importance for comparative genomics and evo-devo approaches. However, expression data from Physcomitrella patens were so far generated using different gene annotation versions and three different platforms: CombiMatrix and NimbleGen expression microarrays and RNA sequencing. The currently available P. patens expression data are distributed across three tools with different visualization methods to access the data. Here, we introduce an interactive expression atlas, Physcomitrella Expression Atlas Tool (PEATmoss), that unifies publicly available expression data for P. patens and provides multiple visualization methods to query the data in a single web-based tool. Moreover, PEATmoss includes 35 expression experiments not previously available in any other expression atlas. To facilitate gene expression queries across different gene annotation versions, and to access P. patens annotations and related resources, a lookup database and web tool linked to PEATmoss was implemented. PEATmoss can be accessed at https://peatmoss.online.uni-marburg.de

“…It also causes stunted growth and foliage turns dark green colour due to accumulation of starch and sugars in the leaves. Deficiency in leaves disturbs the photosynthetic machinery and electron transport chain through repression of orthophosphate concentration in chloroplast stroma inhibiting ATP synthase activity [12]. Phosphorus is key component of nucleic acids and plant hormones and determines the yield and quality of a crop [13,14].…”

Roots enable the plant to survive in natural environment by providing anchorage and acquisition of water and nutrients. In this study, 153 mungbean genotypes were studied to compare root architectural traits under normal and low phosphorus conditions. Significant variations, medium to high heritability, near normal distribution and significant correlations were observed for studied root traits. Total root length (TRL) was positively correlated with total surface area (TSA), total root volume (TRV), total root tips (TRT) and root forks. The first two principal components explained the 79.19 % and 78.84% of the total variation under normal and low phosphorus conditions. TRL, TSA and TRV were major contributors of variation and can be utilized for screening of phosphorus uptake efficiency at seedling stage. Released Indian mungbean varieties were found to be superior for root traits than other genotypic groups. Based on comprehensive phosphorus efficiency measurement, IPM-288, TM 96-25, TM 96-2, M 1477, PUSA 1342 were found to be best five highly efficient genotypes whereas M 1131, PS-16, Pusa Vishal, M 831, IC 325828 were highly inefficient genotypes. These identified highly efficient lines are valuable genetic resources for phosphorus uptake efficiency that could be used in mungbean breeding programme.
