“…Allahabad Safeda, Sardar (L-49), Lalit, and Shweta and verified as per embryogenic frequency and intensity. Previously, 2,4-D (1.0 mg/l) was also found operative in inducing SE in the cultivar Banarasi local (Akhtar 2010;Rai et al 2007;Akhtar 2013). Lower concentration of 2,4-D (1.0 mg/l) was recommended in few cultivars for embryogenesis, while increased concentrations Fig.…”

“…Phenol exudation and inborn contamination are the two major bottlenecks faced in guava tissue culture. The importance of embryonic tissue as explant source for inducing SE has been well documented (Thorpe et al1991;Dunstan et al 1995) in several woody perennials including guava (Jaiswal and Jaiswal 2005;Rai et al 2007;Akhtar 2010Akhtar , 2013Kamle et al 2013). Therefore, an immature zygotic embryo (IZE) considered the most juvenile explant, especially effective for the induction of embryogenic competency when compared with the mesocarp and an in vitro leaf.…”

“…IZEs are preferred explants in embryogenesis as the developmental stage of explants plays a very critical role in growth of in vitro cultures (Yadava 1996). Numerous research reports are available on the induction of embryogenesis using IZEs (Vilchez et al 2002;Rai et al 2007;Moura and Motoike 2009;Akhtar 2010). According to the recent research findings, 10-week-old embryos of genotype Allahabad Safeda (Kamle et al 2016) proved to Bajpai et al (2008) 9.…”

Guava (Psidium guajava L.) is a highly perishable fruit crop comparable to mango owing to its high medicinal value and intense aroma. The presence of high genetic variability limits the chances of further expansion of guava improvement using biotechnological interventions. Conventional methods of guava improvement encountered with restricted achievement in progress of disease resistant varieties because of existing high genetic variability in the germplasm. There is a considerable demand for the establishment of successful and efficient regeneration protocols via somatic embryogenesis. Plants regenerated through somatic embryogenesis could be more useful than plants obtained through organogenesis because, in most cases, somatic embryos are of single-cell origin, and have a low frequency of chimeras and a high number of regenerations. This review is a snapshot of the recent status of somatic embryogenesis as a basis for expanding genetic improvement in guava for quality traits and future perspectives using advanced technologies.

Cytokinins (CKs) are a chemically diverse class of plant growth regulators, exhibiting wide-ranging actions on plant growth and development, hence their exploitation in agriculture for crop improvement and management. Their coordinated regulatory effects and cross-talk interactions with other phytohormones and signaling networks are highly sophisticated, eliciting and controlling varied biological processes at the cellular to organismal levels. In this review, we briefly introduce the mode of action and general molecular biological effects of naturally occurring CKs before highlighting the great variability in the response of fruit crops to CK-based innovations. We present a comprehensive compilation of research linked to the application of CKs in non-model crop species in different phases of fruit production and management. By doing so, it is clear that the effects of CKs on fruit set, development, maturation, and ripening are not necessarily generic, even for cultivars within the same species, illustrating the magnitude of yet unknown intricate biochemical and genetic mechanisms regulating these processes in different fruit crops. Current approaches using genomic-to-metabolomic analysis are providing new insights into the in planta mechanisms of CKs, pinpointing the underlying CK-derived actions that may serve as potential targets for improving crop-specific traits and the development of new solutions for the preharvest and postharvest management of fruit crops. Where information is available, CK molecular biology is discussed in the context of its present and future implications in the applications of CKs to fruits of horticultural significance.
