“…The coconut tree ( Cocos nucifera L.) is an ancient palm species of great importance in tropical and subtropical areas [ 1 ]. Coconut belongs to the Arecaceae family, which also includes the oil palm ( Elaeis guineensis ) and the date palm ( Phoenix dactylifera L.); these palms are sources of oil (the former) and carbohydrates (the latter) for the food and pharmaceutical industries [ 2 , 3 ].…”

Cocos nucifera L. is a crop grown in the humid tropics. It is grouped into two classes of varieties: dwarf and tall; regardless of the variety, the endosperm of the coconut accumulates carbohydrates in the early stages of maturation and fatty acids in the later stages, although the biochemical factors that determine such behavior remain unknown. We used tandem mass tagging with synchronous precursor selection (TMT-SPS-MS3) to analyze the proteomes of solid endosperms from Yucatan green dwarf (YGD) and Mexican pacific tall (MPT) coconut cultivars. The analysis was conducted at immature, intermediate, and mature development stages to better understand the regulation of carbohydrate and lipid metabolisms. Proteomic analyses showed 244 proteins in YGD and 347 in MPT; from these, 155 proteins were shared between both cultivars. Furthermore, the proteomes related to glycolysis, photosynthesis, and gluconeogenesis, and those associated with the biosynthesis and elongation of fatty acids, were up-accumulated in the solid endosperm of MPT, while in YGD, they were down-accumulated. These results support that carbohydrate and fatty acid metabolisms differ among the developmental stages of the solid endosperm and between the dwarf and tall cultivars. This is the first proteomics study comparing different stages of maturity in two contrasting coconut cultivars and may help in understanding the maturity process in other palms.

<p>Kentang kultivar Atlantik merupakan kentang untuk bahan baku industri pangan. Produktivitas kentang yang rendah disebabkan karena perbanyakan secara konvensional belum dapat menghasilkan benih berkualitas baik. Perbanyakan konvensional terkendala dengan akumulasi patogen, penurunan kualitas serta rendahnya tingkat multiplikasi. Kultur jaringan merupakan metode yang tepat untuk mengatasi permasalahan tersebut. Penelitian ini bertujuan untuk mendapatkan konsentrasi IAA yang tepat pada berbagai macam bahan eksplan kentang Atlantik. Penelitian dilaksanakan pada bulan Juli - Agustus 2020 di Laboratorium Kultur Jaringan Jurusan Agroteknologi Fakultas Pertanian Universitas Pembangunan Nasional Veteran Yogyakarta. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) 2 faktor. Faktor pertama adalah konsentrasi IAA pada taraf 0,5; 1; dan 1,5 ppm; dan faktor kedua adalah macam bahan eksplan yaitu bagian pucuk, bagian tengah, dan bagian pangkal planlet, terdapat 9 kombinasi dan 3 kali ulangan. Pengamatan dilakukan pada 8 MST dengan parameter tinggi planlet, jumlah buku, jumlah tunas samping, jumlah daun, warna daun, panjang akar, dan bobot kering planlet. Hasil penelitian menunjukkan konsentrasi IAA 1 ppm dengan macam bahan eksplan bagian tengah secara interaksi dapat meningkatkan jumlah buku dan jumlah daun planlet kentang Atlantik. Konsentrasi IAA 0,5 ppm secara tunggal dapat meningkatkan tinggi planlet, jumlah tunas samping, panjang akar, dan bobot kering planlet kentang Atlantik. Macam bahan eksplan bagian tengah secara tunggal dapat meningkatkan jumlah tunas samping planlet kentang Atlantik.</p>
