Understanding the epigenetic molecular mechanisms (EMMs) of reproduction is crucial for developing advanced and targeted control strategies for Spodoptera frugiperda. Differential expression analysis revealed 11 known miRNAs with varying expression levels, including nine upregulated and two downregulated miRNAs, in virgin females compared with males. The predictive analysis identified 426 target genes for these miRNAs, with ribogenesis highlighted as a key process in oogenesis and egg fertilization.

Article Synopsis
  • - The research utilized machine learning techniques on a 34-year meteorological time series for estimating wheat yield in five Punjab districts, applying models like stepwise multi-linear regression, artificial neural network, and random forest.
  • - Wheat yield at different crop growth stages was estimated using weather data, with models trained and validated in R software showing strong performance metrics like MAPE and nRMSE below 6%.
  • - Among the models tested, random forest outperformed others (SVR and DNN) for yield estimation accuracy, particularly in the Faridkot, Ferozpur, and Gurdaspur districts.

  • Early seedling vigour (ESV) is crucial for rice cultivation, particularly in direct-seeded systems, and the aus varietal group shows high ESV.
  • A study of 181 aus accessions revealed significant genetic variation in ESV traits, and the vegetative vigour was closely linked to overall plant performance.
  • Genome-wide association studies identified 14 significant QTLs associated with ESV, including novel QTLs, and pinpointed candidate genes that may enhance seedling vigour and grain yield in breeding programs.

Sesame (Sesamum indicum L.) is an ancient oilseed crop belonging to the family Pedaliaceae and a globally cultivated crop for its use as oil and food. In this study, 2496 sesame accessions, being conserved at the National Genebank of ICAR-National Bureau of Plant Genetic Resources (NBPGR), were genotyped using genomics-assisted double-digest restriction-associated DNA sequencing (ddRAD-seq) approach.

In the modern era, intensive agricultural practices such as agrochemicals are applied in excessive amounts to enhance agricultural production. However, imbalanced adoption of these chemicals has arisen in the dwindling of agriculture factor productivity and soil quality. To maintain soil fertility and production, these chemical fertilizers must be supplemented with organic inputs.

The mutant matrilineal (mtl) gene encoding patatin-like phospholipase activity is involved in in-vivo maternal haploid induction in maize. Doubling of chromosomes in haploids by colchicine treatment leads to complete fixation of inbreds in just one generation compared to 6-7 generations of selfing. Thus, knowledge of patatin-like proteins in other crops assumes great significance for in-vivo haploid induction.

Salinity is a serious environmental factor that impedes crop growth and drastically reduces yield. This study aimed to investigate the potential of halophilic archaea isolated from the Rann of Kutch to alleviate the negative impact of salinity on crop growth and yield. The halophilic archaea, which demonstrated high tolerance to salinity levels up to 4.

Article Synopsis
  • Researchers studied sesame plants using a method called RAD-seq to see which technique, single-digest or double-digest, worked better for analyzing their DNA.
  • They found big differences in the genetic details between the sesame samples, which helped them identify the most diverse types of sesame in their study.
  • The study also gave suggestions on how to improve RAD-seq methods for analyzing larger groups of plants in future research.

  • Subclinical mastitis (SCM) significantly affects milk production in buffaloes and is linked to changes in DNA methylation that influence gene expression.
  • The study analyzed whole-genome DNA methylation and mRNA levels in healthy versus SCM-affected buffaloes, revealing lower methylation in SCM cases and identifying nearly 4,000 differentially methylated regions.
  • Important genes involved in immune response were found to be downregulated in SCM, indicating DNA methylation may be a key regulatory mechanism impacting this condition in dairy buffaloes.

Phosphorus (P), an essential nutrient required by plants often becomes the limiting factor for plant growth and development. Plants employ various mechanisms to sense the continuously changing P content in the soil. Transcription factors, such as SHORT ROOT (SHR), AUXIN RESPONSE FACTOR19 (ARF19), and ETHYLENE-INSENSITIVE3 (EIN3) regulate the growth of primary roots, root hairs, and lateral roots under low P.
