Do So

Tomato (Lycopersicon esculentum Mill.) is used as vegetable or fruit by people around the world. The effective and efficient propagation of tomato is needed due to the high demand, while its availability is not enough to meet the consumer demand. In vitro flowering and fruiting is useful in order to produce high quality hybrid seeds. Also, this can be produced in all seasons. Beside, this technique is beneficial to improve genetic diversity in tomato. In addition, tomato has natures that make it compatible as a plant model. This experiment intended to find the best combination of plant growth regulators or plant retardants  to induce flower and fruit from tomato plantlets. The results will be beneficial to overcome self-fertilization in tomato, as well as to promote higher genetic biodiversity in tomato. To do so, some plant growth regulators (6-Benzylaminopurine (BAP), Indoleacetic acid (IAA), and Gibberellin (GA3)) and retardants (Ancymidol and Paclobutrazol) were used to find the best combination in inducing in vitro flowering and fruiting. The results showed that 1 mg.L-1 BAP was the best candidate plant growth regulator to produce the in vitro flowers and fruits from the treated plantlets.

Disease Free

Ginger (Zingiber officinale Roscoe) var. Bentong is a monocotyledon plant that belongs to the Zingiberaceae family. Bentong ginger is the most popular cultivar of ginger in Malaysia, which is conventionally propagated by its rhizome. As its rhizomes are the economic part of the plant, the allocation of a large amount of rhizomes as planting materials increases agricultural input cost. Simultaneously, the rhizomes’ availability as planting materials is restricted due to the high demand for fresh rhizomes in the market. Moreover, ginger propagation using its rhizome is accompanied by several types of soil-borne diseases. Plant tissue culture techniques have been applied to produce disease-free planting materials of ginger to overcome these problems. Hence, the in vitro-induced microrhizomes are considered as alternative disease-free planting materials for ginger cultivation. On the other hand, Bentong ginger has not been studied for its microrhizome induction. Therefore, this study was conducted to optimize sucrose and plant growth regulators (PGRs) for its microrhizome induction. Microrhizomes were successfully induced in Murashige and Skoog (MS) medium supplemented with a high sucrose concentration (>45 g L−1). In addition, zeatin at 5–10 µM was found more effective for microrhizome induction than 6-benzylaminopurine (BAP) at a similar concentration. The addition of 7.5 µM 1-naphthaleneacetic acid (NAA) further enhanced microrhizome formation and reduced sucrose’s required dose that needs to be supplied for efficient microrhizome formation. MS medium supplemented with 60 g L−1 sucrose, 10 µM zeatin and 7.5 µM NAA was the optimum combination for the microrhizome induction of Bentong ginger. The in vitro-induced microrhizomes sprouted indoors in moist sand and all the sprouted microrhizomes were successfully established in field conditions. In conclusion, in vitro microrhizomes can be used as disease-free planting materials for the commercial cultivation of Bentong ginger.

Amygdalus Communis

The Almond (Amygdalus communis) is one of the most important and oldest commercial nut crops, belonging to the Rosaceae family. Almond has been used as base material in pharmaceutical, cosmetic, hygienically and food industry. Propagation by tissue culture technique is the most important one in woody plants. In the current research, in vitro optimization of tissue culture and mass production of almond was investigated. In this idea, explants of actively growing shoots were collected and sterilized, then transferred to MS medium with different concentrations and combinations of plant growth regulators. The experiment was done in completely randomized blocks design, with 7 treatment and 30 replications. After 4 weeks, calli induction, proliferation, shoot length and number of shoot per explants were measured. Results showed that the best medium for shoot initiation and proliferation was MS + 0.5 mg/l IAA (Indol-3-Acetic Acid) + 1 mg/l BA (Benzyl Adenine). Autumn was the best season for collecting explants. The shoots were transferred to root induction medium with different concentrations of plant growth regulators. The best root induction medium was MS + 0.5 mg/l IBA (Indol Butyric Acid).

Abstract Passiflora xishuangbannaensis (Passifloraceae) is endemic to a few sites of Mengyang nature reserve in Yunnan, Xishuangbanna and less than 40 individuals have been recorded. Nine Passiflora species are endemic to Yunnan with most species occurring in South America, making P. xishuangbannaensis highly significant and emblematic to the conservation work in the region. This study is designed to provide the first protocol for in vitro organogenesis and plant regeneration for ex situ conservation and reintroduction for an Asian Passiflora species. Using internodes, petioles and tendrils we optimize calli formation and root elongation using several plant growth regulators, individually or in combination. We also assess the genetic stability of regenerated cells. The maximum callus induction and shoot bud differentiation were both achieved on half Murashige and Skoog basal medium supplemented with 4.44 µM 6-Benzylaminopurine and 1.08 µM 1-Naphthaleneacetic acid. The best rooting was achieved from 30 days old, regenerated shoots on half Murashige and Skoog basal medium supplemented with 1.08 µM 1-Naphthaleneacetic acid. Micropropagated plants were subjected to inter simple sequence repeat markers analyses. Collectively, 86 bands were generated from 6 primers of which 12 bands were polymorphic, showing genetic variation between the regenerated plantlets and the original plant. Response to plant growth regulators was more specific than most other studies using South American species, which could be explained by the morphological and physiological differences between South American and Asian Passiflora species
