Wild Oryza species are being targeted for commercial cultivation due to their high nutritional grain profile, and association with Aboriginal people in many regions. Australian wild have potential as high-value, low-volume, culturally identified, nutritious food, especially gourmet tourism, restaurants, value-added products. However, the basic agronomic protocols a field crop unknown. In this r...
Abstract Clearfield™ (CL) rice ( Oryza sativa L.) is a weedy spp.; synonym = red rice) control tool that has been used in Brazil since 2003. This system includes the use of an imidazolinone (IMI)-tolerant cultivar and application IMI herbicides. In this review article, Brazilian weed scientists evaluate challenges lessons learned over 18 yr CL use. benefits include selective control, better cro...
Comparative genomics is a powerful tool to decipher gene and genome evolution. Placing multiple genome comparisons in a phylogenetic context improves the sensitivity of evolutionary inferences. In the genus Oryza, this comparative approach can be used to investigate gene function, genome evolution, domestication, polyploidy, and ecological adaptation. A large genomic region surrounding the MONO...
Panicle architecture determines the number of spikelets per panicle (SPP) and is highly associated with grain yield in rice (Oryza sativa L.). Understanding the genetic basis of panicle architecture is important for improving the yield of rice grain. In this study, we dissected panicle architecture traits into eight components, which were phenotyped from a germplasm collection of 529 cultivars....
Endophytic persistence of inoculated plant growth promoting bacteria (PGPB) involves interaction with the host and host’s indigenous endophytic bacterial communities. This study investigated Methylobacterium oryzae CBMB20 into rice endosphere together impact inoculation on diversity community structure root shoot endophytes in Oryza sativa L. spp. indica cv. IR29. Terminal Restriction Fragment ...
Bacterial artificial chromosome (BAC) physical maps embedding a large number of BAC end sequences (BESs) were generated for Oryza sativa ssp. indica varieties Minghui 63 (MH63) and Zhenshan 97 (ZS97) and were compared with the genome sequences of O. sativa spp. japonica cv. Nipponbare and O. sativa ssp. indica cv. 93-11. The comparisons exhibited substantial diversities in terms of large struct...
The wild Oryza species are rich in genetic diversity and are good resources for modern breeding of rice varieties. The reliable ex situ conservation of various genetic resources supports both basic and applied rice research. For this purpose, we developed PCR-based and co-dominant insertion/deletion (INDEL) markers which enable the discrimination of the genome types or species in the genus Oryz...
background: physical characteristics of crops play an important role in designing the required machinery and apparatus for planting, harvesting, transport, processing and also storing. the aim of this study was to determine physical characteristics of some native rice varieties cultivated in northern iran, namely gerde, shafagh, tarom-e-hashemi, shiroodi and keshvari. methods: some geometrical,...
انتشار phytophthora parsiana گونه جدید گرمادوست درچند استان های جنوبی کشور و دامنه میزبانی چوبی آن در شرایط مایه زیاد بیمارگر در گلخانه مطالعه گردید. فعالیت بیمارگر در طول آزمایش در خاک مایه زنی شده ردیابی شد. از میان گیاهان چوبی مایه زنی شده بادام از تمام گونه ها حساسیت بیشتری داشت. از 24 گونه گیاهان چوبی شدت بیماری از زیاد به کم به ترتیب بادام، زرد آلو، پسته رقم سرخس، بادام پوست کاغذی، خربزه ...
