The study including two experiments was arranged in a completely randomized design with two factors. For callus induction, the culture medium supplemented with concentrations of TDZ combined with concentrations of NAA was used, while to induce shoots, concentrations of BA combined with concentrations of NAA were added to the medium.

The objective of the study was to find the explant resources, the type and concentration of plant growth regulators (PGRs), as well as the in vitro culture conditions suitable for different morphogenesis processes - callus induction, direct embryogenesis, shoot and root formation, etc. The growth and development of in vitro Ngoc Linh ginseng derived from thin cell layer (TCL) was examined in Quang Nam to assess the adaptability of in vitro Ngoc Linh plantlets in its natural territory, compared to those growing in Bidoup - Nui Ba National Park, Lam Dong.

The development of fruits without fertilization is known as parthenocarpy. Parthenocarpy improves the fruit quality, processing attributes, production and productivity of vegetable crops like tomato, cucumber, watermelon etc. Absence of seeds can enhances the shelf life of the fruits, allowing a better conservation, fruit set in adverse climatic conditions, early and offseason production of vegetable crops. Therefore, it is important to ensure yield stability regardless of environmental conditions.

Phytochromes are photoreceptor proteins that monitor the light environ-ment and regulate a variety of photomorphogenic responses to optimize the growth and development of plants. Phytochromes comprise N-terminal photosensory and C-terminal regulatory domains. They are mutually pho-toconvertible between a red-light-absorbing (Pr) and a far-red-light-absorb-ing (Pfr) form. Their interconversion by light stimuli initiates downstream signaling cascades.

Jasmonic acid and its methyl ester are ubiquitous plant sig-nalling compounds necessary for the regulation of growth and development, as well as for the response of plants to environmental stress factors. To date, it is not clear whether methyl jasmonate itself acts as a signal or if its conversion to jasmonic acid is mandatory prior to the induction of a def-ense response. We have cloned a cDNA, encoding a methyl jasmonate-cleaving enzyme, from tomato cell suspension cultures.

Calpains are intracellular Ca 2+ -regulated cysteine pro-teases which mediate regulatory cleavage of specific substrates. They cover a broad range of physiological functions including proteolysis of molecules involved in cytoskeletal organization, the cell cycle, signal trans-duction, apoptosis, and protein renewal during growth and tissue regeneration. Originally found in mamma-lian skeletal muscle then in numerous organisms inclu-ding protists and plants, their expression is ubiquitous [1,2].

Homeobox genes play a critical role in regulating various aspects of plant growth and development. In the present study, we identified a total of 107 homeobox genes in the rice genome and grouped them into ten distinct subfamilies based upon their domain composition and phylogenetic analy-sis.

Introduction - Regulatory Aspects All pesticides sold or distributed in the United States (US) must be registered with the EPA (US Environmental Protection Agency) for the intended uses and must have safety data to show that they can be used without posing unreasonable risks to humans and the environment. Ethephon (2-chloroethylphosphonic acid) is classified as an organophosphate pesticide.
