Definitions
- the present invention relates to Brussels sprout, kale, cauliflower or cabbage plants substantially not, or not, comprising sinigrin and progoitrin. Formulated differently, the present invention relates to non-bitter tasting Brussels sprout, kale, cauliflower or cabbage plants.
- the present invention further relates to seeds, progeny, edible parts, egg cells, callus, suspension culture, somatic embryos, clones, embryos, or plant parts, or cells of the present plants and methods for providing or selecting the present plants.
- Brassica oleracea is a member of the Brassicaceae family or crucifers (Cruciferae). This species has many cultivars, which encompass several food crops. The most important of these cultivars are Brassica oleracea var. acephala (kale); Brassica oleracea var. alboglabra, (Chinese kale); Brassica oleracea var. botrytris (cauliflower and Romanesco broccoli); Brassica oleracea var. capitata (red and white cabbage, Savoy cabbage); Brassica oleracea var. gemmifera (Brussels sprouts); Brassica oleracea var.
- gongylodes (kohlrabi) and Brassica oleracea var. italica (broccoli); Each of these cultivars has been selected and is cultivated for a specific part of the plant. For example, white and red cabbage have prominent leaves, Brussels sprouts are formed by the axial buds of the Brassica plant, while cauliflower is white inflorescence meristem, and broccoli is formed by the flower head of the plant.
- Brussels sprouts are typically 1.5-4.0 cm in diameter and resemble miniature cabbages. They comprise fresh and tender lobules formed in axillary buds of edible plants, and the lobules are soft in texture, rich in taste, unique in flavor, and easy to refrigerate and keep fresh.
- Brussels sprouts grow in temperature ranges of 7-24 °C and are ready for harvest 3 to 6 months after planting.
- the edible sprouts grow like buds in helical patterns along the side of long, thick stalks. Sprouts may be picked by hand or mechanically depending on the variety.
- Harvest season in temperate zones of the northern latitudes is September to March, making Brussels sprouts a traditional winter-stock vegetable.
- Brussels sprouts are predominantly cultivated in the Netherlands, UK, France, Germany and Belgium. They are also cultivated in Mexico, USA and in China. Brussels sprouts are a rich source of vitamins C and K as well as Bl, B6, folate and minerals. They are sui table for diets, since they regulate the intestine and the excretion of the body fluids; they are also low in calories and a good source of protein (3.5 g protein/100 gr raw vegetable). Additionally, Brussels sprouts have anticarcinogenic properties.
- Brussels sprouts are highly appreciated for their cooking properties and particular taste, similar to the rest of the cabbages. They are typically cooked by boiling, steaming, stir frying, grilling or roasting. A generally undesirable characteristic of Brussels sprouts is biterness. Albeit bitterness is appreciated by some, it is disliked by many consumers, mostly children. This creates a need to provide Brussels sprouts that are less, or not, bitter.
- the cultivar headed cabbage has a wide phenotypic range. There are more flat varieties but also rounded and pointy-headed cabbages. Their shape can be bred according to the demand of a given market. The demand for a particular shape of the headed cabbage can change over time. Previously, markets generally preferred headed cabbage with large heads, while currently smaller cabbages are in demand. Beyond shape, there is a rather large variation in cultivation days till harvest between varieties. Early cultivars and varieties mature in 60 days, while late types need 150 growing days. Varieties can also vary in leaf position, waxiness of the heads, the size of the head, the shape of the head, and internal core length.
- Headed cabbage is a rich source of nutrients such as vitamins Bl, B6, folate, vitamin C, vitamin K and to a lesser extent the vitamins B2 and B3. Headed cabbage contains glucosinolates and glycosides. These compounds significantly contribute to the characteristic taste of headed cabbage.
- Cauliflower is cultivated in different climates ranging from Northern Europe to India. Plants for commercial production are typically started in a greenhouse from seeds. After about 35 to 40 days cauliflower seedlings are transplanted to the field, where they are grown for another 40 - 300 days, depending on variety and local growing conditions, to maturity and harvest. During the curd initiati on phase the meristem of the cauliflower plant forms a generative bud; this bud will develop into the mature flower head, or curd, which is the harvested and marketed part of the plant. Some cauliflower varieties require vernalization. Typically, only the head is eaten - the edible white flesh is sometimes called "curd". When cauliflower is mature, heads appear clear white, compact, and 15-20 cm in diameter.
- Cauliflower is a source of carbohydrates, fiber and protein and contains negligible fat, as well as vitamins B, C and K. Cauliflower contains several non -nutrient phytochemicals common in the cabbage family including isothiocyanates and glucosinolates.
- Kale also known as leaf cabbage, belongs to a group of cabbage cultivars grown for their edible leaves, although some are used as ornamentals. Kale plants have green or purple leaves, and the central leaves do not form a head (as with headed cabbage). Kales are considered to be closer to wild cabbage than most of the many domesticated forms of Brassica oleracea. Kale is a hardy vegetable and thrives in wintertime, surviving in temperatures as low as -15.0°C, Celsius. Kale can become sweeter after a heavy frost.
- the nutrient rich kale is a source of carbohydrates, proteins and fat as well as vitamins, including K, C, A, E and to a lesser extents group B vitamins and dietary relevant minerals: manganese, magnesium, potassium, iron, phosphorous and calcium.
- the phytochemicals found in kale include the carotenoids lutein and zeaxanthin and polyphenols such as ferulic acid.
- kale contains glucosinolate compounds (e.g. glucoraphanin) that contribute to its overall taste.
- Glucosinolates constitute a class of organic compounds that contain sulfur and nitrogen and are derived from glucose and an amino acid. There are at least 132 known chemical structures and these compounds are mainly found in cruciferous plants. GLS and mostly their enzymatic hydrolysis products are versatile bioactive compounds. They can have negative effects: e.g., attracting diamondback moth, a pest of cruciferous plants, which is able to recognize the presence of GLS, allowing it to identify the proper host plant or progoitrin contributing to goiter disease in cattle. They also have positive roles such as anticarcinogenic (sulforaphane), antioxidant and antifungal effect in humans or deterring or toxic activity for some insects (bioinsecticides). Biosynthesis process of these compounds is very complex but also well studied in Arabidopsis and Brassica species.
- glucosinolates Based on the amino acid glucosinolates are derived from, these compounds can be divided into three classes: (1) aliphatic GSLs derived from alanine (Ala), leucine (Leu), isoleucine (lieu), valine (Vai), and methionine (Met); (2) aromatic GSLs derived from phenylalanine (Phe) and tyrosine (Tyr) and (3) indolic GSLs derived from tryptophan (Trp). Aliphatic GSL are the most abundant group and in Brassica crops most GLS are synthesized from methionine.
- the biosynthetic pathway has three main phases: elongation of amino acids by insertion of methylene groups into their side chains, followed by reconfiguration of the amino acid moiety to yield a core structure of the glucosinolate and lastly modification stage where secondary transformations take place that result in the final structure of the glucosinolate.
- Aliphatic pathways typically starts with methionine, which is deaminated to the corresponding 2-oxo acid by a branched chain amino acid aminotransferase (BCAT). Then, a sequential addition of single methylene groups to the side chain of the 2-oxo acid takes place in three reactions involving methylthiolalkylmalate (MAM), an isopropylmalate isomerase (IPMI), and isopropylmalate dehydrogenase (IPMDH) yielding an elongated 2-oxo-acid. Subsequently the elongated 2-oxo-acid can either proceed through another elongation round or can be transaminated by a BCAT to the corresponding chain elongated amino acid.
- MAM methylthiolalkylmalate
- IPMI isopropylmalate isomerase
- IPMDH isopropylmalate dehydrogenase
- cytochrome P450 catalyzes the conversion of the amino acid derivatives to aldoximes, oxidized later by CYP83s into nitrile oxides, transformed to thiohydroximates via glutathione (GSH) S-transferases (GSTFs) and the C-S lyase (SURI) reaction, and finally converted to the GLS core structure by S- glucosyltransferases (UGT74s) and sulfotransferases (SOTs).
- GSH glutathione
- GSTFs glutathione S-transferases
- SURI C-S lyase
- GSH is produced by the action of specific ligases (GSH1 and GSH2) from cysteine, glutamate, and glycine and ensures sulfur supply for GLS biosynthesis, yielding GSH conjugates.
- GSH specific ligases
- Alkenylation, benzoylation, glycosylation, hydroxylation, methoxylation, oxygenation, and sulfonation may affect the elongated amino acid, increasing the chemical structure diversity of GLS.
- the methylthioalkyl GLS are S-oxygenated in a reaction catalyzed by flavin monooxygenases (FMOGS-OXs) to methylsulfmylalkyl GLS, such as 4- methylsulfmylbutyl-GL (Glucoraphanin) or 4-methylsulfmylpropyl (Glucoiberin).
- FMOGS-OXs flavin monooxygenases
- Glucoiberin and Glucoraphanin are substrates for 2- oxa acid dependent dioxygenase (AOP2 or ALK).
- AOP2 gene product converts these methylsulfmylalkyls into alkenyl glucosinoplates. In the case of the conversion of glucoiberin the final product of the pathway is sinigrin.
- the final product from glucoraphanin is progoitrin.

- Example 1 Development of non-bitter Brussels sprouts.
- Seeds were harvested and the new line was morphologically identical to the original Brussels sprouts line in a field trial with the exception that the newly created Brussels sprout was not bitter. Moreover, a taste test was performed to validate the effect of the introgression with the non-functional AUK gene, see Example 4.
- Brussels sprouts were sampled by taking 5 sprouts picked at a random fashion from the stem. Plants that grew on the borders were not sampled as they had more space and nutrition, which could influence the glucosinolate content in the sprouts due to different availability of nutrients such as nitrate. To help the subsequent freeze drying step, the picked sprouts were cut into smaller pieces. 50 gram of fresh material was taken to obtain 5 grams of freeze dried material.
- Fresh material was frozen in freezer at -20°C and subsequently freeze dried under vacuum in an Edwards freeze dryer. To avoid enzymatic break down of glucosinolates, care was taken not to defrost the samples in the process.
- LC-MS was used to determine the glucosinolate levels in the samples.
- the detection limit was 3 micromole per 100 gram fresh material.
- the measurement error is according to the norm SANCO/12571/2013 E13 https://www.eurl- pesticides.eu/library/docs/allcrl/AqcGuidance_Sanco_2013_12571.pdf.
- a value of zero means the measurement is under the detection limit (3 micromole/ 100 gram fresh weight or less)
- Control plants Plants with the same genetic background as the deposit but with a functional ALK gene.
- ALK gene is indeed a functional gene for glucosinolate synthesis in Brussels sprouts
- a knockout of ALK was made using CRISPR/Cas9 in a Brussels sprout plant comprising an active ALK gene encoding for a protein having the sequence Seq ID 1.
- Four target sites were identified (SEQ ID Nos. 19 to 23) and used to generate guide RNAs (gRNAs).
- the aim of this modification was to introduce a mutation that will result in a truncated protein.
- the mutation(s) can be either insertion, deletion or another modification.
- an ALK mutant allele can be found in a Brussels sprouts TILLING population by screening and/or resequencing.
- the TILLING population was generated by treating seeds of a Brussels sprouts with Ethyl Methyl Sulfate (EMS). Surviving seedlings were grown into plants and subsequently selfed to obtain M2 seeds. The M2 seeds can be sampled to identify ALK mutants. Plants that have a nonsense mutation in ALK can be selected and backcrossed several times, while selecting for the mutation. This will result in Brussels sprouts with a defect in the glucosinolate synthesis pathway, namely in the in the step of production sinigrin due to the absence of active ALK gene.
