Abscission layer (AL) at the base of flower in rice using laser micro-dissection: NIL(qSH1) AL vs. Nipponbare AL, NIL(qSH1) AL vs. NIL(qSH1) upper region of AL, and NIL(qSH1) AL vs. NIL(qSH1) lower region of AL

ABSTRACT: Tissue-specific transcriptional profiling of the abscission layer (AL) at the base of young flower in rice using laser micro-dissection: NIL(qSH1) vs. Nipponbare. We used two rice varieties, NIL(qSH1) and Nipponbare. NIL(qSH1) is a nearly isogenic line containing the seed shattering gene qSH1. Seed shattering is easy in NIL(qSH1), but it is not in Nipponbare. So, we used some stages of young flower in NIL(qSH1) and some in Nipponbare. Four regions: 1. abscission layer region of NIL(qSH1), 2. upper abscission region of NIL(qSH1), 3. lower abscission layer region of NIL(qSH1), and 4. abscission layer region of Nipponbare. Sample experiments: NIL(qSH1) AL vs. Nipponbare AL, NIL(qSH1) AL vs. NIL(qSH1) upper region of AL, and NIL(qSH1) AL vs. NIL(qSH1) lower region of AL.

Developing endosperm: Nipponbare vs NIL(TGW6)

Project description:Gene expression profoling of developping endosperm at 3 and 6 days after flowering (DAH): Nipponbare vs NIL(TGW6) We used two rice varieties, NIL(TGW6) and Nipponbare.NIL(TGW6) is a nearly isogenic line containing the thousand grain weight qTGW6. For samples used three stages: 3 and 6 DAH endosperm in both Nipponbare and NIL(TGW6). Two dye swapped experiments were performed.

RNA-seq analysis of NIL-GAF1 and NIL-gaf1 grains of 15 DAF at filling stage

Project description:Favorable grain filling ability is crucial for seed development and plant yield1, with less fertilizer applying is the most urgent goals to meet the growing demands of green and safe food. However, the balance mechanism between grain filling and nutrient elements is still unclear so far. Here, we describe a gene GAF1, specially expressed in endosperm aleurone layer, encoding a phosphate transporter, positively controls rice grain filling and seed development and also contributes to phosphate balance was mapped in our study. To study the regulation pattern of GAF1, we performed the RNA-seq analysis of NIL-GAF1 and NIL-gaf1 at middle grain filling stage in seeds. The data shows that many pathways related to starch and sugar metabolism were enriched, and many starch synthesis related genes and phosphate response genes were up-regulated or down-regulated. These data further support that seed specific expressed GAF1 plays a key role in regulating both phosphate homeostasis and seed development. More importantly, overexpression of GAF1 can significantly improve grain filling and thus yield enhanced plant production in field.

Comparative gene expression analysis between Nipponbare and 6-4 under two conditions

Project description:Nipponbare performs poorly in phosphorus (P) deficient soil whereas a Nipponbare-derived NIL containing the Pup1 allele of donor parent Kasalath is tolerant to P deficiency. In this experiment we compared gene expression patterns in roots of this NIL to Nipponbare, grown either in a P deficient or P fertilized soil. The aim is to separate constitutive differences in expression from those induced by P deficiency. Keywords: genotype comparison, constitutive differential expression

Small RNA analysis of ASR5 knockdown rice plants (ssp. Japonica cv. Nipponbare) under Al stress conditions

Project description:Aluminum (Al) toxicity in plants is one of the primary constraints in crop production. Al³⁺, the most toxic form of Al, is released into soil under acidic conditions and causes extensive damage to plants, especially in the roots. In rice, Al tolerance requires the ASR5 gene, but the molecular function of ASR5 has remained unknown. This data establish a comparative study of miRNAome profiles in ASR5 knockdown rice plants (ssp. Japonica cv. Nipponbare) under Al stress conditions.
