Measurements of the endogenous cytokinin and indole-3-acetic acid (IAA) contents in both hypocotyl explants and seedlings with regenerated shoots (HRSs and SRSs) suggested that the observed differences in organogenic response between these two types of explants were related to their cytokinins and IAA contents.

Prolonged culturing of embryogenic tissue on PGR-free medium led to somatic embryo development into plantlets that were successfully acclimated in the greenhouse with a survival rate of 72.5%.
Optimization of In Vitro Regeneration from Leaf Explants of Apple Cultivars Golden Delicious and Melrose
An efficient in vitro shoot regeneration method from leaf explants of apple cultivars Golden Delicious and Melrose by optimization of regeneration medium, explant type and orientation, dark pre-treatment, and gelling agent is presented, with satisfactory regeneration frequency compared with media gelled with Phytagel ™.
Extraordinary Adaptive Plasticity of Colorado Potato Beetle: “Ten-Striped Spearman” in the Era of Biotechnological Warfare
After reviewing hundreds of scientific papers dealing with CPB control, it became clear that even biotechnological means of control, if used alone, would not defeat the Colorado potato beetle.
Co‐expression of the proteinase inhibitors oryzacystatin I and oryzacystatin II in transgenic potato alters Colorado potato beetle larval development
Although feeding on OCI/OCII leaves did not affect larval survival, coexpression of OC genes reduced the development time and thus significantly decreased plant damage caused by CPB larvae.
Hairy root culture as a valuable tool for allelopathic studies in apple.
An autonomous and permanent in vitro hairy root culture system is highlighted as a valuable tool for studying allelopathic potential of apple, offering new perspective for allelopathy background elucidation in this important fruit species.
Overexpressing AtCKX1 in Potato Plants grown In Vitro: The Effects on Cytokinin Composition and Tuberization
It is concluded that cytokinin deficiency has distinct effects on tuber induction and tuber initiation/growth, possibly mediated by distinct signaling mechanisms.
Pyramiding rice cystatin OCI and OCII genes in transgenic potato (Solanum tuberosum L.) for resistance to Colorado potato beetle (Leptinotarsa decemlineata Say)
Results show that pyramiding of the OCI and OCII genes could be an effective strategy for breeding cultivars exhibiting elevated levels of resistance to CPB, indicating an additive effect against Colorado potato beetle.
Endogenous levels of cytokinins, indole-3-acetic acid and abscisic acid in in vitro grown potato: A contribution to potato hormonomics
Endogenous levels of all analytically detectable isoprenoid cytokinins, as well as the auxin indole-3-acetic acid (IAA), and abscisic acid (ABA) have been determined in shoots and roots of 30 day old in vitro grown potato (cv. Désirée).
Integrating the Roles for Cytokinin and Auxin in De Novo Shoot Organogenesis: From Hormone Uptake to Signaling Outputs
An integrative interpretation of the roles for CK and auxin in the process of DNSO is provided, adding emphasis on their uptake from the regeneration media and their interaction with sucrose present in the media to their complex signaling outputs that mediate shoot regeneration.
