Abstract Rice is a crucial food crop globally. Soil salt stress has adverse effects on the physiology and biochemistry of rice, leading to ionic toxicity and disrupted metabolism. Research aimed at improving salt tolerance and understanding its underlying mechanisms in rice is becoming increasingly important. Phytohormones are crucial in managing rice’s reaction to salt stress by controlling its physiological and biochemical functions. Some phytohormones can improve salt tolerance in rice by affecting gene programming, protein expression, and salt stress signaling, thereby helping rice adapt to salt-stressed environments. This review highlights recent advancements in understanding how various More >

Abstract Although tocopherols are essential for rice development, the molecular details by which their absence affects development remain to be determined. To study how tocopherols function during rice development, we performed a transcriptome deep sequencing (RNA-seq) analysis of the rice cultivar Nipponbare (Nip) and the tocopherol-deficient mutant small grain and dwarf 1-2 (sgd1-2). We identified 563 differentially expressed genes that were enriched in Gene Ontology categories associated with metabolism, stress, cellular responses, and transcriptional regulation. We determined that the total fatty acid composition of Nip and sgd1-2 was comparable, although cell membrane penetrability in sgd1-2 was significantly higher than… More >
