Rice blast is caused by Magnaporthe oryzae, which is the most destructive fungal pathogen affecting rice growing regions worldwide. The rice blast resistance gene Pib confers broad-spectrum resistance against Southeast Asian M. oryzae races. We investigated the allelic diversity of Pib in rice germplasm originating from 12 major rice growing countries. Twenty-five new Pib alleles were identifie...

Abstract Elastomeric material is used as blast-resistant structure because of its good mechanical properties.A series underwater near-field explosive tests at different standoff distances were conducted to investigate the anti-explosion performance steel structures covered with rubber and polyurea coatings. The experimental results demonstrated that both could enhance blast resistance test plat...

Abstract One of the biotic constraints in rice production worldwide is blast disease which can control by planting resistant varieties. To find out effective resistance, resistance quantitative trait loci (QTL) were mapped against 20 and 3 virulent isolates for leaf neck blast, respectively, using 111 doubled haploid lines from cross IR64 Azucena. QTLs associated with found on chromosomes 1, 2,...

Many plant mutants develop spontaneous lesions that resemble disease symptoms in the absence of pathogen attack. In several pathosystems, lesion mimic mutations have been shown to be involved in programmed cell death, which in some instances leads to enhanced disease resistance to multiple pathogens. We investigated the relationship between spontaneous cell death and disease resistance in rice ...

Resistance to explosive loads is one of the most important aspects of the design of critical structures due to the wide range of threats. With the widespread use of concrete in the development of explosion-resistant structures, there is much research on the response of concrete components against dynamic loads such as explosion and impact in the technical literature. This paper experimentally a...

The columns of frame structures are the key load-bearing components and the exterior columns are susceptible to attack in terrorist blasts. When subjected to blast loads, the columns would suffer a loss of bearing capacity to a certain extent due to the damage imparted which may lead to their collapse and even cause the progressive collapse of the whole structure . The concrete-filled steel col...

PURPOSE Flavopiridol is a cyclin-dependent kinase inhibitor currently undergoing human clinical trials. As clinical development is pursued, it becomes important to evaluate resistance mechanisms to flavopiridol. To elucidate the contribution of breast cancer resistance protein (BCRP) to cellular resistance to flavopiridol in acute myeloid leukemia, we studied the relationship between cellular r...

Experimental and numerical investigations are carried out to determine how thin steel plates with pre-cut defects behave under blast loading. The considered in this study represented by four square holes, symmetrically distributed around the centre of target plates. were manufactured from two types steel, i.e., a dual-phase medium strength high-strength martensitic steel. A shock tube facility ...

A meta-analysis was performed to understand the role of zinc finger domains in proteins of resistance (R) genes cloned from different crops. We analyzed protein sequences of seventy R genes of various crops in which twenty six proteins were found to have zinc finger domains along with nucleotide binding sites - leucine rice repeats (NBS-LRR) domains. We identified thirty four zinc finger domain...

Rice blast disease is one of the most destructive rice diseases worldwide. The pi21 gene confers partial and durable resistance to Magnaporthe oryzae. However, little is known regarding the molecular mechanisms of resistance mediated by the loss-of-function of Pi21. In this study, comparative transcriptome profiling of the Pi21-RNAi transgenic rice line and Nipponbare with M. oryzae infection a...
