“…In agricultural production, our investigation showed that the formation of turmeric tubers may be related to water-deficit conditions. A study showed that the expression levels of CURS and DCS were upregulated in turmeric under water-deficit conditions (Chintakovid et al, 2022), which was consistent with the expression pattern of the tuber formation stage (Tu1 to Tu2). In addition, the difference in curcumin content between rhizomes and tubers reflected the remodeling of secondary metabolites under environmental stress, which was related to plant defense in response to abiotic stresses (Obata and Fernie, 2012;Zhu, 2016).…”

Curcuma longa, known as the ‘golden spice’ and ‘life spice’, is one of the most commonly utilized spices in the world and also has medicinal, cosmetic, dye and flavoring values. Herein, we present the chromosomal-level genome for turmeric to explore the differences between tubers and rhizomes in the regulation of curcumin biosynthesis and the mechanism of tuber formation. We assembled the turmeric genome into 21 pseudochromosomes using Pacbio long reads complemented with Hi-C technologies, which has a total length of 1.11 Gb with scaffold N50 of 50.12 Mb and contains 49,612 protein−coding genes. Genomic evolutionary analysis indicated that turmeric and ginger have shared a recent WGD event. Contraction analysis of gene families showed possible roles for transcription factors, phytohormone signaling, and plant-pathogen interactions associated genes in adaptation to harsh environments. Transcriptomic data from tubers at different developmental stages indicated that candidate genes related to phytohormone signaling and carbohydrate metabolic responses may be associated with the induction of tuber formation. The difference in curcumin content between rhizomes and tubers reflected the remodeling of secondary metabolites under environmental stress, which was associated with plant defense in response to abiotic stresses. Overall, the availability of the C. longa genome provides insight into tuber formation and curcumin biosynthesis in turmeric as well as facilitating the understanding of other Curcuma species.

“…The genus Curcuma (family Zingiberaceae) comprises more than 110 native species and is distributed in tropical and subtropical regions [ 1 , 2 , 3 ]. The leaves and rhizomes of Curcuma accumulate considerable amounts of active components such as phenols, flavonoids and saturated fatty acids [ 4 , 5 , 6 , 7 ]. The flowers have a wide range of medicinal and ornamental uses [ 8 , 9 , 10 ].…”

Curcuma is extensively cultivated as a medicinal and ornamental plant in tropical and subtropical regions. Due to the bright bract color, distinctive inflorescence and long blooming period, it has become a new favorite in terms of the urban landscape, potted flowers and cut flowers. However, little research on breeding new cultivars using traditional plant breeding methods is available on the genus Curcuma. In the present study, pollen viability and stigma receptivity evaluation were performed, and the genetic relationship of 38 Curcuma accessions was evaluated, then 5 C. alismatifolia Gagnep. (Ca), 2 C. hybrid (Ch), 2 C. sparganiifolia Gagnep. cultivars and 4 Curcuma native species were selected as parents for subsequent interspecific cross-breeding. A total of 132 reciprocal crosses were carried out for interspecific hybridization, including 70 obverse and 62 inverse crosses. Obvious discrepancies among fruit-setting rates were manifested in different combinations and in reciprocal crosses. Results showed that the highest fruit-setting rate (87.5%) was observed in the Ca combinations. There were 87 combinations with a fruit-setting rate of 0%, which meant nearly 65.9% was incompatible. We concluded that C. alismatifolia ‘Siam Shadow’ (Ch34) was suitable as a male parent and C. petiolata Roxb. (Cpet) was suitable as a female parent to improve the fruit-setting rates. The maximum number of seeds per fruit (45.4) was obtained when C. alismatifolia ‘Chiang Mai Pink’ (Ca01) was used as a female parent followed by C. attenuata Wall. ex Baker (Catt) (42.8) and C. alismatifolia ‘Splash’ (Ca63) (39.6) as male parents. The highest germination rate was observed for the Ca group followed by Catt and C. sparganiifolia ‘Maetang Sunrise’ (Csms). The germination rates of Ca accessions ranged from 58.2% (C. alismatifolia ‘Siam Scarlet’ (Ca06) as a male parent) to 89.3% (C. alismatifolia ‘Sitone’ (Ca10) as a male parent) with an average value of 74.0%. Based on the results of hybrid identification, all the individuals from the four combinations exhibited paternal-specific bands, indicating that the true hybrid rates of crossings were 100%. Our results would facilitate the interspecific hybridization and introduction of genetic variation from wild species into the cultivars in Curcuma in the future, which could be helpful in realizing the sustainable application in urban green areas.
