The yellow stem borer (YSB), Scirpophaga incertulas, is a prominent pest in rice cultivation causing serious yield losses. The larval stage is an important stage in YSB, responsible for maximum infestation. However, limited knowledge exists on the biology and mechanisms underlying the growth and differentiation of YSB. To understand and identify the genes involved in YSB development and infestation, so as to design pest control strategies, we performed de novo transcriptome analysis at the first, third, fifth, and seventh larval developmental stages employing Illumina Hi-seq.

Proper control of DNA replication is critical to ensure genomic integrity during cell proliferation. In addition, differential regulation of the DNA replication program during development can change gene copy number to influence cell size and gene expression. Drosophila melanogaster serves as a powerful organism to study the developmental control of DNA replication in various cell cycle contexts in a variety of differentiated cell and tissue types.

We developed a computational pipeline that uses gene expression datasets for inferring relationships among genes and predicting their importance. We showed that the capacity of our pipeline to integrate spatial and temporal transcriptional datasets improves the performance of inference algorithms. The combination of this pipeline with Arabidopsis stem cell-specific data resulted in networks that capture the regulations of stem cell-enriched genes in the stem cells and throughout root development.

Breeding for salinity tolerance in rice requires dependable screening techniques. A population was developed from a cross between OM1490 (high yielding variety and short duration from Cuu Long Delta Rice Research Institute (CLRRI) as female parent and Pokkali as male parent (a donor in many breeding programs and salinity tolerance related studies from Indian).

To meet the food demands of a rising global population, innovative strategies are required to increase crop yields. Improvements in plant photosynthesis by genetic engineering show considerable potential towards this goal. One prospective approach is to introduce a CO₂-concentrating mechanism into crop plants to increase carbon fixation by supplying the central carbon-fixing enzyme,

This study assesses the effects of heat on meiotic progression and grain number in hexaploid wheat (Triticum aestivum L. var. Chinese Spring), defines a heat-sensitive stage and evaluates the role of chromosome 5D in heat tolerance. Plants were exposed to high temperatures (30 or 35 °C) in a controlled environment room for 20-h periods during meiosis and the premeiotic interphase just prior to meiosis.

Recently, a number of approaches have been developed to repurpose the CRISPR/Cas9 system as a sequence-specific transcriptional activator for gain-of-function experiments (CRISPR activators, or “CRISPRa”). While multiple CRISPRa strategies have been characterized in cell culture, little is known about their performance in vivo. We present an optimized strategy for generating a large-scale CRISPRa resource in Drosophila and show that this system has a high success rate and generates easily recognizable phenotypes in vivo

All photosynthetic organisms regulate efficiency of excitation energy transfer (EET) to fit energy supply to biochemical demands. For desiccation-tolerant desert crust cyanobacteria this ability is of the utmost importance. These organisms spend most of the daytime in the desiccated state whence absorbed energy is completely quenched. Based on our observations we propose a model where in the hydrated state the organized rod structure of the light-harvesting phycobilisome supports directional EET to reaction centers with minimal losses to thermal dissipation.

How heterochromatin affects RNA processing is unclear. The chromatin regulators ASI1 and EDM2 function in regulating alternative polyadenylation at genes with intronic heterochromatin. We found that ASI1 and EDM2 are associated in planta through interactions with a putative RNA-binding protein, AIPP1. Protein interaction assays suggest that the RNA Pol II C-terminal domain phosphatase CPL2 and two other proteins (AIPP2 and AIPP3) are associated with the ASI1-AIPP1-EDM2 complex.

In the rice blast fungus Magnaporthe oryzae, the cAMP-PKA pathway regulates surface recognition, appressorium turgor generation, and invasive growth. However, deletion of CPKA failed to block appressorium formation and responses to exogenous cAMP. In this study, we generated and characterized the cpk2 and cpkA cpk2 mutants and spontaneous suppressors of cpkA cpk2 in M. oryzae. Our results demonstrate that CPKA and CPK2 have specific and overlapping functions
