Abstract

In Vitro Callus and Plant Regeneration Rate of Tarabas Rice on Several Concentrations of 2,4-D The Agricultural Research and Development Agency and the West Java Provincial Government are developing new superior varieties with Japonica rice standards, namely the Tarabas variety. However, the equivalence of somatic embryogenesis ability of Tarabas rice with original Japonica variety has not been reported. In this study, the frequency of callus regeneration of Tarabas vs Hwayoung rice varieties was compared. Induction of callus from mature embryos with several concentrations of 2,4-D showed the same extent of callus formation in both rice varieties. Callus induced by 1 ppm of 2,4-D showed the higher rate of shoot formation. On the other hand, percentage of callus formation of Tarabas rice was not affected by the increase of 2,4-D concentrations and was able to show 100% regeneration rate  at the fourth week in the regeneration medium, although the shoot growth was not as fast as those from medium with 1 ppm 2,4-D. Therefore, these results suggest that Tarabas variety has a somatic embryogenesis capacity equivalent to that of japonica rice and has the potential as research objects in the field of biotechnology. Badan Penelitian dan Pengembangan Pertanian serta Pemerintah Provinsi Jawa Barat mengembangkan varietas unggul baru dengan standar padi Japonica yaitu varietas Tarabas. Namun, kesetaraan varietas Tarabas dengan varietas Japonica asli dalam kemampuan embriogenesis somatik belum dilaporkan. Penelitian ini membandingkan respons kultur jaringan antara beras Tarabas dan padi Japonica varietas Hwayoung. Induksi kalus dari embrio matang dengan beberapa konsentrasi 2,4-D menunjukkan respons pembentukan kalus yang sama pada kedua varietas padi. Kalus yang diinduksi 1 ppm 2,4-D menunjukkan laju pembentukan tunas yang lebih tinggi. Di sisi lain, kalus Hwayoung yang diinduksi konsentrasi 2,4-D yang lebih tinggi menunjukkan penghambatan dalam pembentukan tunas. Di lain pihak, pembentukan kalus padi Tarabas tidak terpengaruh oleh peningkatan konsentrasi 2,4-D dan mampu menunjukkan 100% laju regenerasi tanaman pada minggu keempat di media regenerasi walaupun pertumbuhan tunas tidak secepat pada perlakuan 1 ppm 2,4-D. Karena itu, hasil penelitian ini menunjukkan bahwa varietas Tarabas memiliki kapasitas embriogenesis somatik yang setara dengan padi japonica dan padi Tarabas mempunyai potensi sebagai obyek penelitian di bidang bioteknologi.

Abstract

The pandan scent in aromatic rice has been known as the result of 8 bp deletions and 3 Single Nucleotide Polymorphisms (SNPS) in BADH2 gene, which produce non-functional betaine aldehyde dehydrogenase (BADH) enzyme. Several DNA markers for aromatic character based on mutation in BADH2 gene have been developed. In our experiment, we analysed the presence of aromatic character in four local rice variety such as Merah Wangi, Pendok, Genjah Arum, and Mentik Wangi Susu using KOH method and DNA molecular method using three DNA markers to detect mutation that responsible for the development of aromatic character. Phenotype analysis using KOH method showed that Merah Wangi, Genjah Arum, and Mentik Wangi Susu produce pandan scents. PCR analysis using Bradbury and Badex7-5, and RM223 markers showed the presence of BADH2 mutation in Merah Wangi and Mentik Wangi Susu, whereas Pendok and Genjah Arum did not show BADH2 mutation using those used three markers. Our results indicate that among four investigated local rice, only Merah Wangi and Mentik Wangi Susu are categorized as aromatic rice whereas Pendok and Genjah Arum are non-aromatic.Keywords: genetic analysis, aromatic rice, specific markers, genetic mutation.

Abstract

Plants activate the unfolded protein response as part of cellular adaptation, thereby maintaining the endoplasmic reticulum homeostasis during external stresses exposure. In this study, we examined the relationship between the degree of salt tolerance and unfolded protein response-related gene expression in India salt-tolerant Pokkali and INPARI 35 varieties compared to the Indica salt-sensitive counterpart IR64 and INPARI 4 varieties.  Our result showed that the salt tolerance of Pokkali and INPARI 35 had been confirmed by their higher survival rate, higher chlorophyll content, lower electrolyte leakage, and lower H2O2 and malondialdehyde content under salt stress conditions. Furthermore, the expression of unfolded protein response genes was highest in INPARI 35, whereas IR64 and INPARI 4 exhibited low gene induction during endoplasmic reticulum stress conditions. Among the four examined varieties the salt tolerant Pokkali surprisingly showed the lowest induction of all examined unfolded protein response-related genes. These results indicated the possibility that unfolded protein response supports the rice plant for adapting to the saline environment.

Abstract

This study aimed to investigate the correlation between callus regeneration rate and the expression of several genes responsible for cytokinin response and ethylene biosynthesis in the Ciherang, Mentik Wangi Susu, Hwayoung and Tarabas rice varieties. The callus regeneration rate of each rice variety was in vitro tested using N6 media, while the gene expression during the callus regeneration stages was examined using quantitative real‐time PCR (qRT‐PCR). Our results showed that the callus of Ciherang and Mentik Wangi Susu showed earlier green spot formation that then turned brown at a later stage, resulting in a low regeneration rate. While Hwayoung and Tarabas showed late green spot formation, high shoot regeneration was observed in both calluses. Gene expression analysis of regeneration media‐grown calluses showed that two cytokinin‐responsive genes, OsRR2 and OsRR6, were highly expressed in the Ciherang and Hwayoung callus, respectively. We also observed that ethylene biosynthesis genes such as OsACS1 and OsACO1 were highly expressed in the Mentik Wangi Susu and Hwayoung callus, respectively. Moreover, the expression of OsBBM1 was high in Hwayoung and Tarabas. Thus, the positive correlation between the expression of cytokinin‐responsive and ethylene biosynthesis genes with somatic embryogenesis activity likely depends on the induction level of OsBBM1.

Abstract

Rice (Oryza sativa L.) production is limited by bacterial leaf blight (BLB), caused by Xanthomonas oryzae pv. oryzae (Xoo). For decades, researchers have attempted to control this disease by growing plants with blight‐resistant Xa genes. Genetic resources often vary between rice varieties, and there is little information about the genetic resources of the pigmented rice varieties widely grown in Indonesia and their resistance genes against Xoo. The purpose of this study was to determine the expression of Xa genes in pigmented rice such as Inpari 24 and Cempo Merah (red‐pigmented) along with Hitam Bantul (black‐pigmented) and white rice varieties IR64 and Ciherang, and to evaluate their resistance to BLB. All varieties carried the Xa4, Xa10 and xa13 genes but varied in the Xa1, Xa7 and Xa21 genes. The rice varieties expressed some of these genes only after inoculation with Xoo. Disease assessment categorised the three different pigmented rice varieties as resistant (Ciherang, Cempo Merah and Hitam Bantul), while IR64 (white) and Inpari 24 (red) were moderately resistant. There was no specific pattern of Xa genes possession, quality of expression or resistance level to X. oryzae pv. oryzae. Therefore, when breeding plants, the selection of parental variety must be considered in terms of the possession and expression of Xa genes such as Xa10 as a molecular marker for resistance.
