“…Menurut Austen et al, (2019), saat tanaman mengalami cekaman abiotik maka metabolisme sekunder tanaman akan beralih ke jalur yang memakan energi yang banyak. Hal ini dapat dilihat dari perbandingan hasil produksi tanaman kelapa sawit kontrol yang lebih tinggi jika dibandingkan dengan perlakuan pada pengujian material tahan kekeringan (Corley, 2018). Stres abiotik pada tanaman merupakan kondisi di mana faktor-faktor lingkungan di sekitarnya memberikan dampak negatif yang menyebabkan perubahan, bahkan hingga tingkat fungsional (Ben-Ari dan Lavi, 2012).…”

Oil palm is known as a plantation crop that produces vegetable oil which is widely used in human life. Palm oil is produced from fresh fruit bunches (FFB) which originate from female flowers. Another part of the oil palm plant that has not been widely utilized is the oil palm leaves. When these leaves have been pruned, they will become abundant garden waste. Apart from that, there are empty palm oil bunches (tankos) which are classified as factory waste. Further research is needed regarding the compound content, especially the secondary metabolite content of midrib and tankos so that their utilization is optimal. The aim of this review is to determine the content of secondary metabolite compounds in oil palm plants and the potential for wider use. The method used is collecting library data, reading, analyzing and writing it down. The data and references used are scientific articles in national and international journals, textbooks, literature reviews and other sources. Based on the review, information was obtained that oil palm leaves contain several secondary metabolite compounds, especially saponins and phenols, while tankos contains phenol compounds. The amount of secondary metabolite compound content is not yet known for certain and this could be an opportunity to conduct research to determine the content of secondary metabolite compounds, especially for oil palm plants.

“…Produksi metabolit sekunder ini seringkali diiringi dengan penurunan biomassa yang cukup signifikan (Niinemets, 2015). Pada kelapa sawit terjadi penurunan produksi mencapai 18% dari kontrol pada pengujian material toleran kekeringan (Corley et al, 2018).…”

“…Perakitan bahan tanaman yang adaptif di lahan marjinal serta toleran terhadap cekaman biotik dan abiotik adalah hal yang penting. Faktor iklim seperti kekeringan berkepanjangan, suhu rendah-tinggi dan sebagainya menjadi faktor pembatas produktivitas kelapa sawit (Corley, Rao, Palat, & Praiwan, 2018;Rival, 2017). Ketahanan kelapa sawit terhadap serangan hama penyakit juga turut menjadi perhatian demi keberlangsungan kelapa sawit itu sendiri (Durand-Gasselin et al, 2011).…”

Metabolomik merupakan kajian mengenai metabolit yang diekspresikan oleh organisme sebagai respon pembacaan fisiologis akibat pengaruh genetik dan lingkungannya. Kajian tersebut memiliki manfaat yang luas pada program pemuliaan kelapa sawit, Program pemuliaan kelapa sawit memasuki era perakitan bahan tanaman resisten/toleran cekaman biotik dan abiotik sebagai karakter sekunder di samping karakter utama komponen produksi yang tinggi. Kajian metabolomik bisa digunakan untuk penapisan material-material genetik tanaman putatif resisten atau toleran terhadap cekaman biotik dan abiotik. Selain itu, kajian metabolit pada kultur in vitro kelapa sawit juga dapat digunakan untuk mengidentifikasi biomarka yang terkait proses pembentukan somatik embrio maupun profil metabolit/fitohormon pada kultur yang normal maupun abnormal. Tulisan ini mengulas metabolomik, meliputi jenis kajian, tahapan kajian, alat pendukung serta contoh aplikasinya pada pemuliaan kelapa sawit. Mengingat manfaatnya, metabolomik perlu dikembangkan untuk mendukung program pemuliaan kelapa sawit.

“…One of the main cons of going somewhere outside the Amazon Biome, more specifically to the Mid-West and Northeast regions in Brazil, is that there oil palm will face long periods of drought throughout the year when it will not receive the physiological water level required to maintain productivity and will demand the use of artificial irrigation. Accordingly to Corley et al [3], oil palm requires ~2,000 mm/year of water and does not tolerate water deprivation for more than 90 days.…”

In recent years, many studies have reported that several distinct families of transcription factor (TF) genes play crucial roles in the response of plants to abiotic stress. Although some of these families got systematically studied in many species, little knowledge exists about these genes in oil palm (Elaeis guineensis Jacq.). In this study, 20 genes differentially expressed in the leaves of oil palm plants subjected to salinity or drought stress and encoding TFs belonging to four families of TFs - MYB, HD-ZIP, NF-Y, and HSFF - got selected for further characterization. The genes underwent a structural and functional annotation, besides having their RNA-Seq expression profile validated by the qPCR technique, and a correlation analysis of their response under both stresses got performed. The annotation analysis of the promoter region showed the presence of seven cis-acting elements, all already reported to be involved in plants' response to abiotic stress. The structural and functional characterization of the proteins encoded by the selected genes showed that some groups present patterns of conserved regions and are orthologs to genes already linked to salinity or drought resistance in other plant species. It was possible to confirm the RNA-Seq expression profile of 19 genes, only gene 4 showed the opposite response when using qPCR. Through correlation analysis, it was possible to observe a high level of similarity in the behavior of the 20 genes in response to drought or salinity stress, a behavior already reported in other species. The results presented here shed light on the role of 20 TFs in the leaves of young oil palm plants under severe levels of soil salinity or water deprivation. The high level of similarity in the molecular response to both stresses allowed the identification of genes that might grant strategies aiming to develop oil palm plants with a tolerance to both salinity and drought at once.
