Single-cell RNA-sequencing (scRNA-seq) is a rapidly growing field in transcriptomics, which generates a tremendous amount of gene expression data at the single-cell level. Improved statistical approaches and tools are required to extract informative knowledge from such data. Gene network modeling and analysis is one such approach for downstream ana...

Delineation of irrigation management zones (IMZs) depend on spatial variability of soil hydro-physical properties like soil texture, bulk density (BD), field capacity (FC), permanent wilting point (PWP) and available water content (AWC). This work presents a method for delineation of irrigation zones under such constraints. A total of 67 geo-refere...

In the present study, the distribution of soil organic carbon (SOC) was investigated using digital soil mapping for an area of ~29 lakhs ha in Bikaner district, Rajasthan, India. To achieve this goal, 187 soil profiles were used for SOC estimation by Quantile regression forest (QRF) model technique. Landsat data, terrain attributes and bioclimatic...

Defining nutrient management zones (MZs) is crucial for the implementation of site-specific management. The determination of MZs is based on several factors, including crop, soil, climate, and terrain characteristics. This study aims to delineate MZs by means of geostatistical and fuzzy clustering algorithms considering remotely sensed and laborato...

In the present study, the distribution of salinity was investigated using digital soil mapping (DSM) algorithms in the 5 km buffer zone of both sides of the Indira Gandhi Nahar Pariyojana (IGNP) canal system of Suratgarh tehsil in Rajasthan. To achieve this goal, 64 soil samples were used with 21 environmental covariates and 3 DSM algorithms. The r...

Background Picrorhiza kurroa Royle ex Benth. being a rich source of phytochemicals, is a promising high altitude medicinal herb of Himalaya. The medicinal potential is attributed to picrosides i.e. iridoid glycosides, which synthesized in organ-specific manner through highly complex pathways. Here, we present a large-scale proteome reference map of...

Formation of mature miRNAs and their expression is a highly controlled process. It is very much dependent upon the post-transcriptional regulatory events. Recent findings suggest that several RNA binding proteins beyond Drosha/Dicer are involved in the processing of miRNAs. Deciphering of conditional networks for these RBP-miRNA interactions may he...

Identifying the factors determining the RBP-RNA interactions remains a big challenge. It involves sparse binding motifs and a suitable sequence context for binding. The present work describes an approach to detect RBP binding sites in RNAs using an ultra-fast inexact k-mers search for statistically significant seeds. The seeds work as an anchor to...

Litterfall production, decomposition and nutrient release was investigated for three prominent agroforestry tree species, Prosopis cineraria, Tecomella undulata and Hardwickia binata, grown in the arid western region of India. The highest litterfall was recorded for H. binata (9.44 Mg ha−l y⁻¹) followed by P. cineraria (8.94 Mg ha−l y⁻¹) and T. und...

Identifying RBP binding sites and mechanistic factors determining the interactions remain a big challenge. Besides the sparse binding motifs across the RNAs, it also requires a suitable sequence context for binding. The present work describes an approach to detect RBP binding sites while using an ultra-fast BWT/FM-indexing coupled inexact k-mer spe...

Background: In-spite of ubiquitous expression of DROSA/DICER, miRNA formation and maturation are highly spatiotemporal implying involvement of other factors in their biogenesis. Several key studies have elucidated functions of few other RNA-binding proteins (RBPs) in miRNAs biogenesis, making it necessary to look miRNA biogenesis models with fresh...

Delineation of management zones (MZs) are needed to manage fields in order to maximize economic return, minimize environmental impact, and improve soil and crop management. The MZs of uniform production potential may offer an effective solution to nutrient management. In this study, a total of 122 geo-referenced representative surface (0–250 mm dep...

In mixture experiments, the response is assumed to depend on the relative proportions of the ingredients present in the mixture and not on total amount of the mixture. When these experiments are conducted with variables that do not form any portion of the mixture, the levels changed could affect the blending properties of the ingredients are called...

The present study was undertaken to investigate the feasibility of estimating the yield of rice based on combined effects of weather parameters and technological advancement, using past weather records for Kheda district of middle Gujarat state. To this end, Autoregressive Integrated Moving Average with Exogenous variables (ARIMAX) time-series mode...

Selection indices are constructed using different weights viz. equal weight, genotypic correlation, phenotypic correlation and path coefficient (direct effects) with all possible combination of traits in forage sorghum (Sorghum bicolor (L.)Moench.) based on six biometrical characters viz. plant height at 50 % flowering (cm), number of tillers per p...

Inappropriate statistical designs may misinterpret results of animal feed experiments. Thus complete statistical designs can make animal feed research more appropriate and cost effective. Usually factorial row-column designs are used when the heterogeneity in the experimental material is in two directions and the experimenter is interested in study...

Most crop datasets contain missing values, a fact which can cause severe problems in the analysis and limit the utility of resulting inference. Classification techniques for grouping of crop genotypes are used when the data is complete. However, the presence of missing values limits the utility of these techniques and creates bias in the resulting...

Pearl millet (Pennisetumglaucum) is one of the most extensively cultivated cereals in the world, ranking fourth after rice, wheat and sorghum. In Gujarat, for last 20 years, it has been noticed that the area under pearl millet production has been decreased gradually although productivity increase. The importance of pearl millet productivity fore...

Salinity is one of the most common abiotic stresses that limit the production of rice. Since, salinity stress tolerance is controlled by many genes, identification of these stress responsive genes as well as to understand the underlying mechanism is of great importance from breeding point of view. In this direction, the reverse engineering of gene...

A timely and reliable forecast of yield of crop needs little emphasis for monsoon dependent country like India where, the economy is mainly based on agricultural production. Weather is a major factor affecting crop production in advanced agricultural systems. The large variation due to climate change in yield from year to year and place to place is...

Correlation and path coefficient analyses are essential tools in selection experiments. They were used to determine direct and indirect relationships between yield and certain plant characters in 40 diverse genotypes of forage sorghum. The estimate of broad sense heritability was highest for green fodder yield plant-1 followed by number of leav...

Genetic variability, heritability and genetic advance studies were necessary for crop improvement which must be exploited for yield improvement. The present investigation was undertaken for 40 diverse genotypes of forage sorghum [Sorghum bicolor (L.) Moench], which were grown in a RCBD with three replications and were evaluated for fifteen characte...

Mixture experiments are the experiments in which the response is a function only of the proportions of the components (constituents) present in the mixture and is not a function of the total amount of the mixture. The mixture experiments have been discussed with their application in agriculture. These experiments are quite useful when the experimen...

Analysis of mixture experiments with process has been discussed in the literature. An experimenter will be interested in optimization of response along with estimation of parameters. If the experimenter has more than two replications the technique of dual response optimization can be used. In this paper we have developed the dual response technique...
