Abstract
Solanum melongena L. commonly known as the eggplant or brinjal comes from the family of Solanaceae, sharing the same ancestor with the tomato and potato. It is an economically important crop worldwide, being well studied for its medicinal properties, nutritional values and its role as an alternative model plant. The eggplant fruit has been previously used for treatments of various diseases such as bronchitis, asthma, arthritis and diabetes as well as its nutritive properties that are beneficial to the human diet. Plant transformation studies on the eggplant have been widely done for the production of transgenic eggplants harbouring genes that are beneficial for optimal plant growth and fruit production. Shoot induction is an essential step required for the successful regeneration of transformed plant tissues and therefore is an essential pre-requisite in Agrobacterium-mediated transformation. The local eggplant cv. Bulat Putih is a local cultivar of eggplant in Malaysia with white and round fruits making it a potential model plant colour pigment accumulation studies in fruit crops. The current work aims to investigate the shoot induction potential of 6-benzylaminopurine (BAP) and Kinetin from cotyledon explants of eggplant cv. Bulat Putih. Results indicated that both BAP and Kinetin were able to induce the regeneration of callus from cotyledon explants. On the other hand, Kinetin at the concentration of 2.0 mg/L successfully induced shoots at the value of 1.50 ± 0.22 shoots per explant, whereas BAP alone did not trigger any formation of shoots. This study indicated that kinetin alone is sufficient to induce shoots in eggplant cv. Bulat Putih without the presence of BAP.
Highlights
Solanum melongena L. with the common name brinjal or eggplant is an economically well-known crop grown in many countries at regions with tropical and temperate conditions (Collonnier et al 2001)
The consumption of the eggplant fruit has been linked to prevention of several diseases such as bronchitis, asthma, diabetes and arthritis, whereby this is mainly due to the presence of phenolic compounds such as chlorogenic acid in its fruit (Pratap et al 2011; Scalzo et al 2016)
The present study describes the regeneration potential of cotyledon explants of eggplant cv
Summary
Solanum melongena L. with the common name brinjal or eggplant is an economically well-known crop grown in many countries at regions with tropical and temperate conditions (Collonnier et al 2001). The eggplant is divided into three main categories according to the shape of their fruits The eggplant is packed with high soluble fiber and mineral contents as calcium, iron, potassium and phosphorus Vitamins such vitamin C, vitamin B-6, vitamin K, folate and choline are considerably high in the fruits making it beneficial to the human health (Bhatti et al 2013).
