“…Similar characteristics were also observed in embryogenic cultures of other species, such as Medicago arborea (Martin et al 2000), Passiflora cincinnata (Silva et al 2009) and P. edulis (Pinto et al 2011), as well as C. papaya cv. Co-7 (Anandan et al 2012).…”

“…Similar features were also observed by Anandan et al (2012) in the embryogenic cultures of C. papaya cv. Co-7 and by others in M. arborea (Martin et al 2000) and Daucus carota ( Jiménez and Bangerth 2001). The beginning of the callus induction occurred on the 7 th day after the incubation of the explant in the induction culture medium, indicating a rapid response compared to other cultivars that had been previously assessed (Farzana et al 2008, Malabadi et al 2011, Anandan et al 2012).…”

Among commercial fruits, papaya (Carica papaya L.) is notably one of the most common ones around the world. The aim of the current study was to establish a somatic embryogenesis protocol for the hybrid UENF/CALIMAN 01, elucidating the effects of ). The 60 g L -1 PEG treatment group had the highest average for the number, maturation and conversion of somatic embryos that resulted in plantlets at the end of the process. The addition of PEG to MS medium led to increased protein synthesis. These results are unprecedented for C. papaya hybrid UENF/CALIMAN 01 as the current study demonstrates the development of somatic embryogenesis in this high quality hybrid.

The objective of the present study was to evaluate the effects of different light emitting diodes (LEDs) on growth, photosynthetic characteristic and chloroplast ultrastructure of upland cotton (Gossypium hirsutum L.) seedlings. Seedlings of the cultivar Sumian 22 were grown under seven different lights including blue (B) plus red (R) LEDs BR (1:8, 1:3, 1:1, 3:1), B LEDs, R LEDs and fluorescent lamps (FL) with the 100 μ mol m -2 s -1 photosynthesis photon flux (PPF) and a 12 hour photoperiod for 40 days. Compared with FL, fresh mass, dry mass, root length, stem width, root activity, length of palisade tissue and stomatal frequencies were significantly greater as well as the thickest grana lamella in chloroplast in seedlings grown under BR1:8 LEDs; The chlorophyll a, chlorophyll b, total chlorophyll contents, photosynthetic rate, leaf thickness, spongy tissue length and stomatal areas were highest in seedlings under B LEDs; The stem length, leaf area, sucrose, soluble sugar and starch concentrations were highest as well as the greatest number and volume of starch grains in chloroplast in seedlings under R LEDs. It was suggested that BR1:8 LEDs might be used as a primary light for the cultivation of upland cotton seedlings under controlled conditions.

“…1). In Medicago arborea, the content of reducing sugars and starch distinguished embryogenic from non-embryogenic callus; while high levels of sugars and low levels of starch were observed in embryogenic cultures, the opposite was observed in non-embryogenic cultures (Martin et al 2000).…”

Feijoa (Acca sellowiana [O. Berg] Burret [Myrtaceae]) is a native fruit species of southern Brazil and northern Uruguay. This species is amenable to somatic embryogenesis and therefore suitable as a model system for comparative studies of zygotic and somatic embryo development. In seed plants, embryogenesis involves three main steps, which are regulated by many factors, such as hormones, proteins, polyamines, and transcription factors. In the present work, the dynamics of protein, sugar, starch, amino acid, and polyamine accumulation were assayed during somatic embryogenesis of A. sellowiana . Protein, starch, amino acid, and polyamine levels accumulated unevenly during the induction phase of somatic embryogenesis, while the sugar content remained stable. Throughout the different developmental stages of somatic embryogenesis, synthesis and accumulation of proteins and amino acids showed patterns similar to those reported previously during the development of zygotic embryos of this same species. Differential patterns of polyamine accumulation were observed. This is important because these compounds affect the synthesis of other endogenous growth regulators, such as auxinindole-3-acetic acid that is mainly involved in the establishment of embryo polarity. Taken together, the present work brings new insights to the physiological and biochemical dynamics that occur during somatic embryogenesis of A. sellowiana.
