Summary: Pyramiding four broad spectrum BB-R genes (Xa4, xa5, xa13 and Xa21) in Basmati-385 background was conducted to obtain drought tolerance and desirable grain traits while having durable resistance against bacterial blight. Line 23 with quadruplet R genes and lines 8, 16, 21, 27, and 28 with triplet R genes were found to have the highest level of resistance. Replicated yield and resistance trials are recommended before releasing these lines as new rice varieties.

Summary: Flooding caused by heavy rainfall and poor soil drainage can negatively affect plant germination and seedling establishment. Rice, however, has unique strategies, such as fast elongation of coleoptiles, to cope with flooding. Microorganisms can contribute to rice health by promoting growth and protecting against stress. A metagenomic analysis of the microbiome during rice germination under submergence revealed distinct compositions of microbiota in different rice varieties, with Arborio seeds showing the development of long coleoptiles. The isolated bacteria were found to have starch hydrolyzing and indole-related compound production abilities under hypoxia. Inoculating these bacteria into submerged rice seeds showed a genotype-dependent response. These findings highlight the importance of endophytic bacteria in promoting rice seedling establishment during flooding.

Summary: The study found that the bacterial and fungal alpha-diversities of the hybrid F1 and self-crossing generations (F2, F3, F4) were closer to one of the two parental lines, indicating a role of the parental line in the diversity of the rhizosphere microbial community assembly. Self-crossing from F1 to F4 led to weak co-variation of the bacterial and fungal communities and distinct rhizosphere microbiomes.

Summary: It was found that OsPAO5 gene expression in rice seedlings is enhanced by light and inhibited by darkness. Mutants created using CRISPR/Cas9 technology exhibited longer mesocotyls, released less H2O2, and synthesized more ethylene, resulting in higher and more uniform emergence rate, showing the potential for direct seeding. Knocking out OsPAO5 can significantly increase grain weight, grain number, and yield potential, providing a novel strategy for breeding elite rice varieties for direct seeding.

Summary: The translation explains that Tre6P maintains sugar balance in plants and promotes growth by regulating carbon allocation. The sugar-inducible rice NAC transcription factor OsNAC23 elevates Tre6P levels and represses trehalose levels by directly repressing the transcription of the Tre6P phosphatase gene TPP1. Additionally, OsNAC23 and Tre6P suppress the activity and transcription of SnRK1a, preventing SnRK1a-mediated degradation of OsNAC23. Overexpression of OsNAC23 increases rice yield and photosynthetic rate.

Summary: This study investigated the mechanism of hormone and reactive oxygen species (ROS) crosstalk in regulating rice dormancy using Zhonghua11 (ZH11) and Introgression line (IL) varieties. Transcriptome and proteome analysis identified differentially expressed genes (DEGs) and proteins (DEPs) between IL and ZH11. Hormone content detection revealed significant differences in abscisic acid (ABA) and jasmonic acid (JA) levels between IL and ZH11. ROS content measurement showed variations in hydrogen peroxide (H2O2) and superoxide anion (O-2(.-)) levels between IL and ZH11. These findings suggest that hormones and ROS play a role in rice dormancy regulation.
