The objective of this study was to investigate the effects drought stress on activity antioxidant enzymes and osmotic adjustment substance content in tillering period drought-sensitive drought-tolerant rice cultivars. results showed that superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), hydrogen peroxide content, soluble protein sugar increased with accumulation time intensity stress. Compared cultivar, drought-resistant cultivar had a smaller photosynthetic affected area, longer...
Abstract Low-temperature germination (LTG) is an important agronomic trait for rice ( Oryza sativa ). Japonica generally has greater capacity at low temperatures than the indica subpopulation. However, genetic basis and molecular mechanisms underlying this complex are poorly understood. Here, we report that OsUBC12 , encoding E2 ubiquitin-conjugating enzyme, increases low-temperature germinability in japonica owing to a transposon insertion its promoter enhancing expression. Natural...
Rice has 48 ubiquitin-conjugating enzymes, and the functions of most these enzymes have not been elucidated. In present study, a T-DNA insertional mutant named R164, which exhibited significant decrease in length primary lateral roots, was used as experimental material to explore potential function OsUBC11. Analysis using SEFA-PCR method showed that insertion promoter region OsUBC11 gene, encodes enzyme (E2), activates its expression. Biochemical experiments is lysine-48-linked ubiquitin...
The Green Revolution gene sd1 has been used extensively in modern rice breeding, especially indica cultivars. However, elite alleles and related germplasm resources for japonica breeding have not identified, extensive efforts are needed to obtain new dwarfing sources. Data from MBKbase-Rice revealed seven haplotypes four rice. Two were identified In 295 accessions northeast Asia, except the weak functional allele SD1-EQ, sd1-r was major allele, reducing plant height comparison with SD1-EQ....
Abstract Rice blast is one of the major fungal diseases that badly reduce rice production in C hina and worldwide. Association mapping for resistance was performed on 226 japonica cultivars with 118 pairs SSR markers. The evaluated by inoculating two isolates, DB 22 77, at tillering stage 2013 2014, separately. A total 31 associations 17 different s were significantly (P < 0.05) associated based mixed linear model ( MLM ), which nine markers could be detected both including simultaneously...
Lodging is one of the major problems in rice production. However, few genes that can explain culm strength within temperate

is considered one of the most damaging plant parasitic nematodes to rice and can cause white tip disease. It was first discovered in Kyushu, Japan 1915 introduced into China from 1940s. The disease mainly found rice-planting areas South (Zhu et al. 2016; Wang 2017; Xu 2019), causing yield losses 30%-50% irrigated (Wang 2014). In summer 2021, plants displaying distortion discoloration on new leaves, tips flag erect shorter panicles, fewer or less filled spikelets were observed field Acheng...
