“…1c, d). BA has been successfully used as inductor of shoot organogenesis in calli and in explants from leaf, petiole, node and internode segments of P. deltoides and its hybrids (Chaturvedi et al 2004;Mingozzi et al 2008;Maheshwari and Kovalchuk 2011;Thakur et al 2012;Cui et al 2014;Kwon et al 2015). However, side effects of too high concentrations of BA, such as decline in shoot bud formation and increase in associated callusing, were observed by Chaturvedi et al (2004), Cui et al (2014) and in the present work.…”

“…Among all the hybrids of Populus, P. x euramericana and P. x interamericana are known to be particularly recalcitrant to shoot organogenesis -mainly if stock plants are adult individuals-and their in vitro morphogenesis ability depends largely on the genotype. In fact, several authors have proved that efficient methods of plant regeneration should be optimized for each commercial clone (Cui et al 2014;Kwon et al 2015;Noël et al 2002). These researchers have used different organogenic pathways, explants and cytokinins to obtain the best results on adventitious shoot induction and growth.…”

“…These researchers have used different organogenic pathways, explants and cytokinins to obtain the best results on adventitious shoot induction and growth. Mingozzi et al (2008) and Kwon et al (2015) even demonstrated that environmental conditions, such as light quality, photon flux and CO2 concentration, may also control bud formation. In addition, regenerated shoots must be properly rooted so that the plants are acclimated successfully.…”

In commercial micropropagation laboratories, the light source is one of the most important factors controlling plant morphogenesis and metabolism of plant cells and tissue and organ cultures. Lamp manufacturers have begun to rate lamps specifically for plant needs. The traditional light source used for in vitro propagation is fluorescent lamps (FLs). However, power consumption in FL use is expensive and produces a wide range of wavelengths (350-750 nm) unnecessary for plant development. Light-emitting diodes (LEDs) have recently emerged as an alternative for commercial micropropagation. The flexibility of matching LED wavelengths to plant photoreceptors may provide more optimal production, influencing plant morphology and chlorophyll content. Although previous reports have confirmed physiological effects of LED light quality on morphogenesis and growth of several plantlets in vitro, these study results showed that LED light is more suitable for plant morphogenesis and growth than FLs. However, the responses vary according to plant species. This chapter describes the applications and benefits of LED lamps on chlorophyll in plant micropropagation. Two study cases are exposed, Anthurium (Anthurium andreanum) and moth orchids (Phalaenopsisis sp.), both species with economic importance as ornamental plants, where LEDs have a positive effect on in vitro development and chlorophyll content.

“…Notably, calli were found to regenerate better under continuous low light exposure than using either constant high light, a 16/8 hour light–dark cycle, or complete darkness [ 158 ]. Low light intensity was also reported to promote shoot proliferation in cotton [ 159 ], and appropriate ratios of blue and red light can enhance regeneration traits in different poplar genotypes [ 160 ]. Curiously, the effects of photoperiod, light quantity, and spectrum are not always consistent between species as light is required for shoot morphogenesis in petunia [ 161 ], whereas it is not essential in tomato (although altered light–dark cycles do affect direct shoot regeneration) [ 162 ].…”

Plant regeneration is essential for survival upon wounding and is, hence, considered to be a strong natural selective trait. The capacity of plant tissues to regenerate in vitro, however, varies substantially between and within species and depends on the applied incubation conditions. Insight into the genetic factors underlying this variation may help to improve numerous biotechnological applications that exploit in vitro regeneration. Here, we review the state of the art on the molecular framework of de novo shoot organogenesis from root explants in Arabidopsis, which is a complex process controlled by multiple quantitative trait loci of various effect sizes. Two types of factors are distinguished that contribute to natural regenerative variation: master regulators that are conserved in all experimental systems (e.g., WUSCHEL and related homeobox genes) and conditional regulators whose relative role depends on the explant and the incubation settings. We further elaborate on epigenetic variation and protocol variables that likely contribute to differential explant responsivity within species and conclude that in vitro shoot organogenesis occurs at the intersection between (epi) genetics, endogenous hormone levels, and environmental influences.
