Hybrid incompatibility plays an important role in establishment of post-zygotic reproductive isolation. To unveil genetic basis of hybrid incompatibilities between diverged species of genus Oryza AA genome species, we conducted genetic dissection of hybrid sterility loci, S22(t), which had been identified in backcross progeny derived from Oryza sativa ssp. japonica (recurrent parent) and South ...

Previous blotch identification algorithms perform identification process for each pixel in current frame, which are time-consuming. To deal with this issue, a blotch identification algorithm based on edge detection is proposed in this work. Above all, edges of current frame are extracted by edge detectors, blotch identification area is limited to edge pixels and pixels nearby. To further reduce...

The net form of net blotch caused by the necrotrophic fungus Pyrenophora teres f. teres is a major disease of barley, causing high yield losses and reduced malting and feed quality. Exploiting the allelic richness of wild barley proved to be a valuable tool to broaden the genetic base of resistance of modern elite cultivars. In this study, a SNP-based nested association mapping (NAM) study was ...

Four new species of Badis are described from West Bengal, India. Badis andrewraoi, new species, is diagnosed by a combination of characters which include absence of a black caudal-fin margin, absence of a conspicuous dark blotch on pectoral-fin base, absence of cleithral and opercular blotches, absence of a blotch on the dorsolateral aspect of the caudal peduncle, absence of an ocellus on the c...

Wild and cultivated Basidiomycetes species were cultured to determine the distribution of bacteria causing brown blotch disease of Agaricus bisporus. Colonies from each basidiocarp were screened for brown blotch organisms by the white line and host pathogenicity tests. Isolates causing brown blotch were identified as Pseudomonas tolaasi and an Arthrobacter species.

We show that chiral Frenkel excitons yield intense circularly polarized luminescence with an intrinsic dissymmetry factor in emission glum as high 0.08. This outstanding value is measured through thin films of cyanine J-aggregates form twisted bundles. Our measurements, obtained by a Mueller polarization analysis, are artifact-free and reveal quasi-perfect correlation between the factors absorp...

The main purpose of this study was to identify species of Parastagonospora in association with poaceous plants in Iran. Some species of Parastagonospora like P. nodorum causes a major loss to wheat production in the world. In the present research, two species including P. nodorum,and P. avenae were identified from different poaceous species. Parastagonospora nodorum was identifiedonPhalaris aru...

OBJECTIVE We studied the effect of swimming on the somatic and bone growth of female rats. METHODS 40 neonate Wistar female rats were separated into: monosodium glutamate group (GluM, n = 20) and received MSG solution (4.0 mg/g) on alternate days during the first 14 days after birth, and Saline group (SAL, n = 20) which received saline solution for the same period of time and at the same dose...

Red leaf blotch is one of the major fungal foliar diseases affecting almond orchards. High-resolution thermal and hyperspectral airborne imagery was acquired from two flights and compared with concurrent field visual evaluations for disease incidence and severity. Canopy temperature and vegetation indices were calculated from thermal and hyperspectral imagery and analyzed for their ability to d...
