As the largest known tree-born fruit in the world, jackfruit (Artocarpus heterophyllus) is an important cultivated crop in tropical regions of South and Southeast Asia. The species has been cultivated in China for more than 1,000 years, but the history of its introduction to the country remain unclear. We assembled a high-quality chromosome-level genome of jackfruit into 985.63Mb with scaffold N50 of 32.81 Mb. We analyzed whole-genome resequencing data of 295 landraces to investigate the domestication history in China and agronomic traits evolution of jackfruit. Population structure analysis revealed that jackfruits of China could be traced back to originate from Southeast Asia and South Asia independently. Selection signals between jackfruit and its edible congener, cempedak (Artocarpus integer), revealed several important candidate genes associated fruit development and ripening. Moreover, analyses of selective sweeps and gene expression revealed that the AhePG1 gene may be the major factor in determining fruit texture. This study not only resolves the origins of jackfruit of China, but also provides valuable genomic resources for jackfruit breeding improvement and offers insights into fruit size evolution and fruit texture changes.

“…Daun cempedak bergantiganti dan tangkai daunnya sepanjang 1-3 cm. Lamina daun berbentuk bulat panjang, ukuran 5-25 x 2,5-12 cm, alasnya berbentuk bundar hingga bulat, warna hijau mengkilap di bagian atas dan hijau pucat serta pudar di bagian bawah [17]. Bunganya merupakan bunga majemuk yang tersusun dalam bunga periuk berbentuk bulat panjang.…”

Profil Fitokimia dan Aktivitas Antioksidan Beberapa Tumbuhan Genus Artocarpus di Indonesia

et al. 2021

Artocarpus merupakan tumbuhan genus utama keluarga Moraceae dengan jumlah spesies hampir 1.400. Beberapa spesies dari genus tersebut dapat dimanfaatkan sebagai makanan dan obat tradisional di Asia Tenggara, termasuk Indonesia. Jenis yang banyak tumbuh di Indonesia yaitu Artocarpus altilis (sukun), Artocarpus camansi (kluwih), Artocarpus heterophyllus (nangka), Artocarpus integer (cempedak), dan Artocarpus odoratissimus (tarap). Tumbuhan tersebut memiliki potensi sebagai bahan obat dan punya nilai gizi yang tinggi. Review ini bertujuan untuk mengkaji perbedaan antar spesies, profil fitokimia, dan aktivitasnya sebagai antioksidan dari kelima tumbuhan tersebut. Narrative review ini ditulis berdasarkan penelusuran literatur yang berupa publikasi artikel penelitian yang ada di basis data Google Scholar, PubMed, dan Science Direct. Selain itu digunakan sumber pustaka lain berupa buku dan naskah tugas akhir untuk memperkaya isi artikel. Hasil kajian literatur terhadap 5 tumbuhan tersebut menunjukkan bahwa beberapa tumbuhan memiliki kemiripan morfologi daun walaupun secara fisik masih bisa dibedakan. Profil fitokimianya memiliki keunikan dengan kandungan utama berupa senyawa fenolik termasuk flavonoid, stilbenoid, arilbenzofuron, dan neolignan yang tersebar pada bagian daun, buah, bunga, dan kulit. Keunikan tersebut ditemui dengan adanya senyawa golongan flavonoid terprenilasi dan tergeranilasi. Senyawa fenolik tersebut mempunyai kemampuan sebagai antioksidan pada beberapa model uji dan potensial untuk dikembangakan sebagai antioksidan atau kandidat obat terutama untuk penyakit yang melibatkan mekanisme radikal bebas dalam mekanisme patofisiologinya.

“…These lectins are used in biomedical research to detect tumors and identify glycoproteins (Lim et al 1997). The wood pulp of A. champeden has essential bioactive compounds, including ascorbic acid and total phenolics (Lopes et al 2018). Several isoprenyl flavonoids with cytotoxicity (Hakim et al 1999) and antimalarial activity (Boonlaksiri et al 2000) have been isolated from A. champeden.…”

2021

Artocarpus champeden Spreng. is a popular fruit tree, grown in tropical and subtropical regions. Besides food, A. champeden is also a medicinal plant with various medicinal properties. In this study, A. champeden chloroplast genome was sequenced, assembled, and annotated due to its rich information on species evolution and inter-species genetic relationships. The quadripartite structure of A. champeden complete chloroplast genome is 158,568 bp in length and comprises a large single-copy region (LSC) of 88,076 bp, a small single-copy region (SSC) of 19,028 bp, and two inverted repeat regions (IRa and IRb) of 25,732 bp. A total of 131 genes were annotated, including 85 protein-coding genes, 37 tRNA genes, eight rRNA genes, and one pseudogene. Phylogenetic analysis revealed a close relationship between A. champeden and A. heterophyllus. In addition, the study provides abundant genomic information for future phylogenetic studies of A. champeden and the Moraceae family.
