Summary: The study found that NaCl can promote the reutilization of root cell wall P in P-starved rice through increasing the activity of pectin methylesterase and the uronic acid content in pectin. Additionally, NaCl can facilitate the translocation of P from root to shoot in P-starved rice, and ABA is involved in the regulation of NaCl-mediated root cell wall P reutilization.

Summary: High temperature is a critical factor affecting rice growth, development, and yield. This study evaluated the heat tolerances of two rice varieties and found differences in their response to heat stress. Analysis of H2O2 and proline content revealed different oxidative and stress responses in the two varieties. Transcriptome analysis identified several pathways involved in heat response, with protein processing in the endoplasmic reticulum playing a key role. Additionally, 22 key genes were identified through protein-protein interaction analysis. This study enhances our understanding of thermotolerance mechanisms in rice and provides a foundation for breeding thermotolerant cultivars through molecular breeding.

Summary: To mitigate the yield plateau in rice, it is crucial to leverage potential technologies and tap into the genetic diversity. This study examined a collection of 200 tropical japonica rice lines from around the world to assess population genetic structure and variability in yield-related traits. The findings suggest that tropical japonica rice lines exhibit significant phenotypic variability, particularly in relation to new plant type phenology. This genetic diversity can be harnessed for hybrid breeding, subject to verification of compatible genes.

Summary: MicroRNAs (miRNAs) interact with specific mRNAs to regulate gene expression at the post-transcriptional level. Some noncoding RNAs possess short open reading frames (ORFs) that code for micropeptides (miPEPs) with regulatory function. MIR genes have dual functions, with longer transcripts processed into miRNAs and shorter transcripts translated into miPEPs. Synthetic miPEPs have been tested for improving stress tolerance/agronomic performance in crop plants. The miPEP-mediated regulatory function holds promise for developing climate-resilient crops.

Summary: Phosphorus (P)-deficiency is a major constraint for global rice production. This study used proteome analysis to investigate the proteins involved in phosphorus acquisition and use efficiency in rice. The results identified differentially expressed proteins (DEPs) related to metabolic processes, transcription factors, and phytohormone signaling. The study also revealed the important role of post-transcriptional regulation in Pup1 QTL under P-starvation stress. These findings provide insights for developing rice cultivars with improved P acquisition and assimilation in P-deficient soil.

Summary: Functional stay-green (FSG) in rice, characterized by delayed senescence during the reproductive stage, was studied using a recombinant inbred line (RIL) population derived from 'Pusa 677'/'PSG16'. The RILs showed significant variation in agro-morphological traits, chlorophyll content, flowering time, yield components, and nitrogen (N) use under different N regimes. Six major quantitative trait loci (QTLs) were mapped, with one QTL on chromosome 1 consistently associated with chlorophyll content and flowering time. The QTL on chromosome 7 was related to grain number, while the QTL on chromosome 6 was associated with N harvest index and spikelet fertility. The FSG trait of 'PSG16' could be valuable in understanding multiple stress responses in rice based on the QTL information.

Summary: Ageing of rice is a complex and beneficial method to improve grain quality after harvest. However, there is limited information on longer periods of rice ageing. This study provides a comprehensive analysis of the nutritional, textural, cooking, pasting, and sensory properties of popular Indian basmati and non-basmati rice varieties aged up to 24 months. The findings suggest that amylose content and resistant starch increase during ageing, while hardness and stickiness decrease. Based on the results, 12-18 months aged basmati rice is recommended for consumers based on their preference for fluffiness and grain length, while 18-24 months aged non-basmati rice is suitable for food industries aiming for crispiness. Further research is needed to understand the effect of storage on rice digestibility.

Summary: Pusa Basmati 1509 (PB1509) is a significant variety of Basmati rice that generates foreign exchange. However, it is vulnerable to bacterial blight and blast. To overcome this, resistance genes were incorporated into PB1509 using different donor parents. Near isogenic lines (NILs) were developed with a genomic similarity ranging from 97.38% to 98.92%. The best-performing individuals were identified and intercrossing led to the generation of improved varieties with comparable agronomy, grain, and cooking quality parameters to PB1509. Cultivating these improved varieties can reduce cultivation costs, decrease pesticide use, and increase productivity while ensuring consumer safety.
