Abstract

Drought is one of the limiting factors in crop cultivation, such as in oil palm (Elaeis guineensis Jacq.). The transgenic approaches are expected to increase plant tolerance to drought stress and minimize low productivity when drought occurs. Proline is an osmoprotectant compound in plants which its biosynthesis involved the P5CS gene. The objective of this study was to evaluate the tolerance level of P5CS-transgenic oil palm to drought stress induced by polyethylene glycol 6000 (PEG-6000). In this present study, the transgenic and non-transgenic oil palms were treated by  0, 2, and 4% PEG-6000 under in vitro conditions. The experiment was arranged as a factorial completely randomized design with three replications. The drought level score, total chlorophyll content, carotenoids, and proline content, as well as P5CS gene expression in leaf tissues were observed at 7 and 14 days after stress treatments. The result showed that transgenic plantlets had a lower drought level score than those of non-transgenic lines. A concentration of 4% PEG-6000 treatment reduced the total chlorophyll and carotenoids contents than that of 2% concentration in non-transgenic plantlets at 7 and 14 day after treatments (DAT). In addition, proline content and P5CS gene expression level in transgenic had been significantly increased during stress treatment. Based on these results, it can be concluded that the P5CS transgene increased the drought stress tolerance of oil palm.

Abstract

Dehydrin is known to have an important role in plant response and adaptation to abiotic stresses including drought and high salinity. Previous research reported the isolation of the full-length coding sequence (CDS) of DHN1 from sugarcane var. PSJT 941, and it shares a high homology with DHN genes from sorghum and other sugarcane varieties. In this study, the full-length CDS was cloned under the constitutive CaMV35S promoter and transformed into sugarcane calli mediated by Agrobacterium tumefaciens. The DHN promoter, Pr-1DHNSo, was also successfully isolated from the sugarcane var. PSJT 941 and cloned into the pBI121 expression vector. The promoter construct was subsequently transformed into sugarcane calli of var. Kidang Kencana. Transgenic sugarcane carrying DHN1 gene and DHN promoter constructs were regenerated according to the standard protocol of sugarcane tissue culture. Optimization of an acclimatization protocol using modified post-rooting media was also conducted and the resulting protocol reduced the total mortality rates of the transformed plantlets. The presence of the gene and promoter constructs was periodically tested by PCR using specific primers. The genotyping results showed that the constructs were present for more than a year after transformation.

Abstract

Genome editing through cisgenesis develops into scientific breakthroughs in accelerating oil palm breeding programs. However, one remaining problem is the low success of transformed-calli regeneration, while its scientific explanation is still underexplored. This study aimed to characterize and regenerate transformed-calli using various amino acids and antioxidants.  Transformed callus that did not regenerate (un-regenerated transformed callus or UTC) after the transformation process was taken, then T-DNA integration was detected using the NPTII gene. Furthermore, the UTC was divided into four types based on morphological characteristics. The four types of UTCs were regenerated on media enriched with glutamine (for Type-1 callus), cysteine and putrescine (for Type-2 callus), and a combination of cysteine and ascorbic acid (for Type-3 and Type-4 callus). The research results obtained NPTII successfully amplified with a band size of 700bp. The results showed that on Type-1 callus, enrichment media with 10 mg L-1 L-glutamine could induce the formation of new nodular structures on UTC Type-1. On Type-2, media enriched with 5 mg L-1 L-cysteine + 20 mg L-1 putrescine increased the density of callus structures. Media enriched with 25 mg L-1 ascorbic acid + 25 mg L-1 L-cysteine could prevent the spread of brown callus on Type-3 callus, while Type-4 callus did not show any response and became dry. Our new findings will facilitate the basic research and unregenerated transformed callus and morphological callus development behavior in oil palm.
