Spinach, Spinacia oleracea L. (2n = 12), is an important leafy vegetable, of which the leaves and tender shoots are consumed fresh or processed. Record Number : 20001608864 Language of text : English. (a) Metaphase chromosomes; (b) merged image; (c) 45s rDNA is red. 17. 1–6 indicate the chromosome number. Spinacia oleracea is a diploid with the chromosome number, 2n=12. Spinach (Spinacia oleracea L., 2n = 2x = 12) is an economically important leafy vegetable that is consumed worldwide (Morelock and Correll 2008).Although the origin of cultivated spinach is uncertain, it is believed to have been domesticated in the area of present Iran, former Persia, around 2,000 years ago (Rubatzky and Yamaguchi 1997; Morelock and Correll 2008). Spinach is native to central Asia, most probably Persia (Iran). Spinach is nutritious and an excellent source of health-promoting compounds and nutrients (Morelock and Correll, 2008). Leaves with margins Leaves with lobed leaf margin 4. Chromosome number 2n=18 Chromosome number 2n=12 3. All spinach chromosomes were identified which will provide valuable information for mapping genes on these chromosomes. bengalensis Hort Botanical name is Spinacea oleracea L 2. All spinach chromosomes were identified which will provide valuable information for mapping genes on these chromosomes. Perhaps S. tetranda is the ancestor of spinach, Spinacia oleracea. . (Color online) Cytological analysis of male spinach by FISH using 45s rDNA as probe. Spinach is a green, leafy vegetable that is high in nutrients and low in calories. The sex gene is located on the short arm of the long chromosome 1. Three cups of raw spinach provides just 20 calories, no fat, 2 grams of protein, and 3 grams of carbohydrate with 2 grams as fiber (so 1 gram of net carbs). ISSN : 0003-1062. Arrows indicate the weak fluorescence signals on chromosomes 1 and 3 of spinach. One cup of raw spinach contains:. There is an increasing demand for spinach in the United States and organic production comprises around 50% of the total production. Spinach (Spinacia oleracea L.) belongs to the family Chenopodiaceae. Give spinach the green light with a bold basil pesto mixture complete with cloves of garlic, peas, and Parmesan. Spinach is annual for leaf production and biennial for seed production. Figure 1. However, Ghaffari and Fasihi-Harandi later proposed a chromosome number of 2n = 24 for P. lentiscus and P. Abstract. Chefs short on time can whip up the dish in 30 minutes or less. The few cytological studies performed to date reveal that the chromosome number of P. vera L. and P. terebinthus L. is 2n = 30 [20–21], as is the case of P. khinjuk Stocks , P. lentiscus L. , P. integerrima L. , and P. eurycarpa Yalt. 3 of 17 The chromosome pair having the sex gene is the longest of the genome. Botanical name is Beta vulgaris var. Spinach is a diploid crop with six chromosomes (2n = 2x = 12). The chromosome number, sex of offspring from virgin females, number of eggs examined, country of origin and food-plant (mostly economic) for each of the 15 … Spinach Beet: Spinach: 1. Spinach (Spinacia oleracea, 2n = 12) and sugar beet (Beta vulgaris, 2n = 18) are important crop members of the family Chenopodiaceae s.s.Sugar beet has a basic chromosome number of 9 and a cosexual breeding system, as do most members of the Chenopodiaceae s.s. family.
