Rice (Oryza sativa; background Nipponbare) contains nine HKT (high-affinity K+ transport)-like genes encoding membrane proteins belonging to the superfamily of Ktr/TRK/HKT. OsHKTs have been proposed to include four selectivity filter-pore-forming domains homologous to the bacterial K+ channel KcsA, and are separated into OsHKT1s with Na+-selective activity and OsHKT2s with Na+-K+ symport activi...
Rice is a very important food staple that feeds more than half the world's population. Two major Asian cultivated rice (Oryza sativa L.) subspecies, japonica and indica, show significant phenotypic variation in their stress responses. However, the molecular mechanisms underlying this phenotypic variation are still largely unknown. A common link among different stresses is that they produce an o...
Microbes constitute a vital part of the plant holobiont. They establish plant-microbe or microbe-microbe associations, forming a unique microbiota with each plant species and under different environmental conditions. These microbial communities have to adapt to diverse environmental conditions, such as geographical location, climate conditions and soil types, and are subjected to changes in the...
High surface ozone concentration is increasingly being recognized as a factor that negatively affects crop yields in Asia. However, little progress has been made in developing ozone-tolerant genotypes of rice-Asia's major staple crop. This study aimed to identify possible tolerance mechanisms by characterizing two quantitative trait loci (QTLs) that were previously shown to influence visible le...
The proper use of resistance genes (R genes) requires a comprehensive understanding of their genomics and evolution. We analyzed genes encoding nucleotide-binding sites and leucine-rich repeats in the genomes of rice (Oryza sativa), maize (Zea mays), sorghum (Sorghum bicolor), and Brachypodium distachyon. Frequent deletions and translocations of R genes generated prevalent presence/absence poly...

Rice has become a major staple cereal in sub-Saharan Africa. Currently, upland rice cultivation is expanding particularly in rainfed areas where the root parasitic weed Striga hermonthica, a major constraint to cereal production, is endemic. Laboratory, pot, and semi-controlled open air experiments were performed to evaluate resistance of selected rice varieties in Sudan to a resident S. hermon...
برنج یکی از مهمترین محصولات غذایی است که غذای تقریباً نیمی از مردم جهان را تأمین میکند. فسفر یکی از عوامل محدودکننده رشد و توسعه برنج میباشد و کمبود آن تأثیر بسیار شدیدی بر عملکرد برنج خواهد داشت. هدف از این مطالعه شناسایی مکانیزمهای بیوشیمیای مقاومت برنج به کمبود فسفر در ریشه و برگ میباشد. متابولیتهای مرتبط با کمبود فسفر در دو لاین والدینی Nipponbare و لاین ایزوژنیک (NIL6-4) که حامل مکان‌ژنی ا...
