Abstract

Lipid is an important biomolecule in plant because of their structural and functional roles in plant cells. Moreover, lipid could be a signal molecule in defense system of plants under biotic and abiotic stresses. Detoxification process of toxic substances, which is one of the defense system and controlled by various genes, plays an important role in tolerance mechanism in plant under stress conditions, including iron (Fe) toxicity. Plants develop various tolerance strategies to cope the Fe toxicity. The objective of this research was to investigate the expression of OsPLA2-III and OsPPO genes under Fe stress condition. Two-weeks-old seedlings of two rice varieties, i.e., IR64 (Fe-sensitive toxicity) and Pokkali (Fe-tolerant toxicity) were used. Both varieties were treated with 1 (control) and 400 ppm of Fe in the form of FeSO4.7H2O in the nutrient culture solution. The leaf bronzing, chlorophyll content, and relative expression of OsPLA2-III and OsPPO genes were observed. An in-silico study was also performed to predict the interaction between OsPLA2-III and OsPPO proteins. The results showed that the Fe toxicity induced leaf bronzing, reduced leaf chlorophyll content, and increased the OsPLA2-III and OsPPO gene expression levels. Both genes are suggested to have a role in plant tolerance mechanism during Fe toxicity stress via lipid signaling pathway.

Abstract

Rice cv. Hawara Bunar is a local rice cultivar tolerant to aluminum (Al) and drought stress. However, the cultivar has inferior characteristics, such as a tall habitus and a small number of tillers, making the cultivar agronomically unattractive. Many genes control plant height and tiller number; one is the TAD1 gene. Analysis of gene expression in two contrasting rice cultivars for both characters is a prerequisite for selecting certain genes for gene editing targets. This study aimed to analyze the gene expression of the TAD1 in rice cv. IR64 and Hawara Bunar, and to construct a phylogenetic tree of genes that regulate rice plant height and tiller number. Gene expression analysis was conducted using the qRT-PCR technique, while the phylogenetic tree was constructed based on the Neighbor-Joining method using PAUP4 software. The results showed TAD1 gene expression in the tillering phase of rice cv. Hawara Bunar is higher than the cv. IR64. The gene expression level in both cultivars corresponds to the plant height and tiller number characters in both rice cultivars. Phylogenetic analysis showed that the TAD1 gene clustered with genes that cause the rice to have a tall habitus with few tillers. The results of a transcriptome meta-analysis reinforced the phylogenetic tree, which shows that the TAD1 gene was found in a group of downregulated genes based on the volcano plots. Therefore, the TAD1 gene can be selected as a target gene for editing in rice cv. Hawara Bunar to obtain superior characters.
