The subject invention provides systems and methods for classifying a microbiome at a geographic site where agricultural activity is, or will be, conducted in order to improve and/or promote agricultural productivity at the site. The subject invention utilizes a large sample set of diverse DNA sequencing input data collected from soil, plant, water and/or air samples, as well as environmental information, to determine relationships between environmental factors and the identities, quantities and distributions of microbial species, taxonomies, and/or groupings thereof, at a chosen site. Machine learning and/or artificial intelligence classifier tools use this information to generate various output data, such as, for example, recommendations for customized soil and/or crop treatment compositions, irrigation practices, and/or other agricultural activity, to enhance plant health and crop productivity at the site.

Early detection of pathogens during asymptotic stage can be useful for timely need based adoption of available methodologies to prevent establishment of the disease and associated yield loss. Beside this, it would be useful for predicting crop productivity and monitoring presence of pathogens in the samples being traded internationally by quarantine departments. Our innovation of designing universal primer to PCR amplify fungal rDNA sequences, restriction digestion of PCR products with HinFl enzyme and analysis of the restriction fragments through PathDec tool leads identification and detection of almost all the fungal pathogens of apple even before visual appearance of the disease symptoms in less than 6 hours.

The present invention provides an estimate of the prior requested in a crop allocation model. The crop allocation model is a mathematical modelling to estimate crop area, yield and production for 42 major crops in the world across a global 5 arc minute grid. The model uses a downscaling approach that accounts for spatial variation in the biophysical conditions influencing the productivity of individual crops, and uses crop gross revenue potential of alternate crops when considering how to prioritize the allocation of specific crops to individual gridcells. The proposed methodology is an entropy-based optimization procedure that imposes a range of consistency and aggregation constraints. A particular feature of this method is the explicit inclusion of error terms. There is inherent uncertainty in many aspects of the model, such as input data, incomplete information on farmers' behavior, spatial heterogeneity of crop varieties and managements cross regions in the world. By explicitly including error terms, this method directly deal with such uncertainties, which leads to better and more reliable estimates.

The present invention includes modified Arabidopsis Nucleoside Di-Phosphate Kinase 2 (NDPK2) nucleic acid molecules whose enzymatic activity have been increased (i.e. hyperactive). NDPKs are ubiquitous housekeeping enzymes that catalyze the transfer of γ-phosphoryl group from a nucleoside triphosphate (NTP) to a nucleoside diphosphate (NDP), and also multifunctional proteins that regulate a variety of eukaryotic cellular activities, including cell proliferation, development, and differentiation. In plants, NDPKs are reported to play a key role in the signaling of both stress and light. Among three NDPKs (NDPK1, NDPK2, NDPK3) in a model plant, Arabidopsis thaliana, NDPK2 was reported as a positive signal transducer of phytochrome-mediated plant light signaling and to regulate cellular redox state, which enhances multiple stress tolerance in transgenic plants. Thus, the plants with the hyperactive NDPK2 are expected to possess higher efficiency of light utilization and enhanced tolerance to various environmental stresses such as cold, salt, and oxidative stresses. Since abiotic stress is one of the most important factors to limit the productivity of many crops, the hyperactive NDPK2 can be used for the development of high-yielding multiple stress tolerant plants with higher efficiency of light utilization. In this invention, several hyperactive NDPK2 were generated by C-terminal deletion and site-directed mutagenesis. Therefore, the present invention can be utilized to develop multiple stress tolerant and efficiently light-utilizing plants, which can eventually increase crop yields. The invention also includes plants having at least one cell expressing the modified NDPK2, vectors comprising at least one portion of the modified NDPK2 nucleic acids, and methods using such vectors for producing plants with enhanced light sensitivity and stress tolerance.
