Genetic mapping reveals a candidate gene for egusi seed in watermelon

Primary mapping of quantitative trait loci regulating multivariate horticultural phenotypes of watermelon (Citrullus lanatus L.)

“…Until now, a total of 61 QTLs (twenty seed length QTLs, nineteen seed width QTLs, 3 seed thickness QTLs, and nineteen QTLs of seed weight) have been identified with major variations in PVE% across the different chromosomal positions of the whole genome chromosome of watermelon “Chr-01, Chr-03, Chr-06, Chr-07, Chr-10, LG-04, and LG-09” using numerous mapping populations derived from crossing of wild type and cultivar parent lines ( Prothro et al., 2012a ; Prothro et al., 2012b ; Sandlin et al., 2012 ; Ren et al., 2012 ; Meru and McGregor, 2013 ; Liu et al., 2014 ; Kim et al., 2015 ; Zhou et al., 2016 ; Li et al., 2018 ; Meru et al., 2018 ; Luan et al., 2019 ; Guo et al., 2020 ; Li et al., 2021 ; Osae et al., 2021 ; Liang et al., 2022 ). In this study, three major QTLs of SWt (SWt-4.1, SWt-5.1, and SWt-10.1), two co-localized QTLs of STh and SL (STh-7.1 & SL-7.1), two major QTLs of SW (SW-4.1 and SW-10.1), one major QTL (SSI-6.1), and one major QTL (SCT-1.1) were detected on six differential chromosomes (Chr-01, Chr-04, Chr-05, Chr-06, Chr-07, and Chr-10) ( Table 2 ; Figure 3 ).…”

“…Further, Cla009301 was found as the homolog of SRS3 (SMALL AND ROUND SEED) for a BY-kinesin-like protein, known as the seed size regulator in rice ( Kanako et al., 2010 ). Further, the relative expression profiling of the Cla007520 gene was noticed to be higher at the early stage of seed formation, but the Cla007520 gene seemed to belong to the CPP protein family and its related amino acid components were similar to those of the AtTSO1 , responsible for promoting cell proliferation initiation during ovule development ( Luan et al., 2019 ). However, seed size and shape, as well as their associated traits, are elastic in nature and change in different environmental locations ( Fisher et al., 2017 ).…”

“…Whole genome sequencing approach coupled with the published de novo reference genome assembly of watermelon has assisted in developing the base-by-base SNP markers and high-resolution genetic linkage mapping ( Guo et al., 2013 ). In recent years, SNP based codominant CAPS markers have been emerged as an efficient DNA markers for dissecting the major-effect QTLs of regulating the important qualitative and quantitative traits of melon and watermelon ( Bang et al., 2007 ; Liu et al., 2015 ; Cheng et al., 2016 ; Liu et al., 2016 ; Li et al., 2017 ; Zhang et al., 2018 ; Liu et al., 2019 ; Luan et al., 2019 ; Wang et al., 2019 ; Sun et al., 2020 ; Amanullah et al., 2020 ; Amanullah et al., 2021 ; Zhang et al., 2021 ; Pei et al., 2021 ; Osae et al., 2021 ; Yang et al., 2021 ; Amanullah et al., 2022 ; Osae et al., 2022 ; Lv et al., 2022 ).…”

Revisiting the scope and applications of food enzymes from extremophiles

“…Examples of enzymes that have been used in this category are keratinases for the degradation of recalcitrant keratinous proteins in hair, horns, wool, feathers, hooves, and nails (Vidmar & Vodovnik, 2018). These keratinous materials typically contain over 85% crude proteins (Luan et al., 2019). Also, they are produced in huge quantities (millions of tons) globally (Korniłłowicz‐Kowalska & Bohacz, 2011), and represent a readily available and excellent bioresource to meet protein needs in food and feed.…”

Assessment of hybrid vigour, dominance effect and hybrids regeneration potential in the genus Citrullus

“…Citrullus mucosospermus is native to sub-Saharan western Africa ( Luan et al., 2019 ). It is an herbaceous food plant, belongs to the family Cucurbitaceae.…”
