. In this study, an investigation was conducted to evaluate the expression of genes encoding SOS1, HKT1, HAK10, and NHX1 transporters in the leaf and root tissues of two contrasting rice cultivars, salt tolerant DP and salt sensitive IR28, under salt stress of 150 mM NaCl by RT-qPCR approach. RT-qPCR data revealed that the expression of HKT1, HAK10, SOS1, and NXH1 were upregulated at a higher level in the DP cultivar than in the IR28 cultivar in response to salt stress treatment.

In this study, we conducted the sequence polymorphisms analysis in the OsHKT1;5 coding region in order to detect the potential allelic variants in some local rice cultivars in Viet Nam. In silico analysis of protein structure and post-translational modifications indicated that amino acid substitutions had no influence on protein structure but led to changes in post-translational modifications such as phosphorylation and SUMOylation.

The study was carried out with twenty-four genotypes of rice during the Spring season, 2020 in Hanoi, Vietnam in order to exploit the attributes and divergence of quality properties from existing rice cultivars in North Vietnam. The rice genotypes were characterized based on ten quality parameters of milling, physical appearance and physiochemical characters using Mahalanobis D2 statistic

Seed-borne rice endophytes are capable of disseminating into host plant tissues as well as to their rhizosphere. Here, we investigated the occurrence of siderophore-producing bacteria (SPB) in the seed endospheres of two distinct rice (Oryza sativa L.) cultivars, TK8 (ssp. japonica) and TCN1 (ssp. indica), and their dissemination into the rhizospheres through culture-dependent methods.

Xanthomonas oryzae pv. oryzae (Xoo) causes severe bacterial leaf blight (BLB) disease to many Vietnamese major rice cultivars, including the TBR225. OsSWEET13 belongs to group III of the OsSWEET gene family encoding sugar transport proteins, which is considered one of the “susceptibility” genes (S genes) necessary for BLB disease.

Climate change and ozone depletion have caused increased ultraviolet B (UVB; 280-315nm) radiation levels on earth, which has been predicted to cause decreased growth and yield of various crops, including rice, the most important staple food worldwide. UVB radiation sensitivity varies extensively in Asian rice (Oryza sativa L.) and African rice (Oryza glaberrima Steud. and Oryza barthii A. Chev.) cultivars, and the activity of cyclobutane pyrimidine dimer (CPD) photolyase that repairs UVB-induced CPD is an essential factor underlying UVB sensitivity in rice.

Microorganisms in the rhizosphere soil play a key role in maintaining the soil fertility, which is a key for successful crop production to meet the increasing global food demand. The aims of this study were to boost growth attributes, yield and nutrient uptake of rice by different treatment combination of plant growth promoting bacteria (PGPB) and NPK fertilizer doses.

The normalized difference spectral index (NDSI) was used to determine significant wavebands that showed the best correlation with leaf ozone injury. The correlation coefficient (r) between NDSI and OIP were ranged from -0.79 to 1. Normalized difference spectral index, NDSI [R564,R568], and NDSI[R558,R573] were identified as the best Pearson’s correlation with leaf ozone injury percentage with correlation coefficient more than 0.96.

This study investigated extracted OS structures derived from three different rice bran AX using Ultraflo Max. Rice bran AX extracted from commercially defatted rice bran (COM) yielded the greatest OS amount (83.39 mg/g RBAX), followed by that of the Sanpahtawng cultivar (27.05 mg/g RBAX), and lastly, the Chainat1 cultivar (21.53 mg/g RBAX), as evidenced via Ultraflo Max enzyme hydrolysis. Interestingly, A3X was the primary OS product in all rice bran AX hydrolysates prepared by Ultraflo Max.

Sheath blight (SB), caused by Rhizoctonia solani, is a common rice disease worldwide. Currently, rice cultivars with robust resistance to R. solani are still lacking. To provide theoretic basis for molecular breeding of R. solani-resistant rice cultivars, the changes of transcriptome profiles in response to R. solani infection were compared between a moderate resistant cultivar (Yanhui-888, YH) and a susceptible cultivar (Jingang-30, JG).

Serotonin, originally identified as a neurotransmitter in mammals, functions as an antioxidant to scavenge cellular ROS in plants. In rice, the conversion of tryptamine to serotonin is catalyzed by SL (sekiguchi lesion), a member of cytochrome P450 monooxygenase family.

Rice (Oryza sativa) occupies a prime position in the family Poaceae and it is the highly consumable crop of almost half of the world's population. Among the various diseases affecting rice, blast incited by Magnaporthe oryzae is the one of the ubiquitous and economically important disease which affects almost all the stages of crop and cause yield loss upto 50%. In the present study, survey was carried out in Nilgiri and Madurai districts of Tamil Nadu for the collection of blast isolates. The blast disease incidence ranged from 8.8 to 42.4 per cent in various rice cultivars.
