Activated charcoal (AC) is highly adsorbent and is often used to promote seedling growth in plant tissue culture; however, the underlying molecular mechanism remains unclear. In this study, root and leaf tissues of 10-day-old seedlings grown via immature embryo culture in the presence or absence of AC in the culture medium were subjected to global transcriptome analysis by RNA sequencing to provide insights into the effects of AC on seedling growth.

Transcriptomic insights into the molecular aspects of salt stress responses in Kandelia candel roots
The mangrove plant Kandelia candel is a type of woody halophyte that grows in tropical and subtropical ocean intertidal zones and exhibits a high salt tolerance. In this study, 61,970 unigenes were obtained from the roots of 60-day-old K. candel seedlings treated with 0 (control), 200, 400, and 600 mM NaCl for 3 days with an N50 of 1510 bp. Moreover, 454, 311, and 2663 genes were differentially expressed under 200, 400, and 600 mM NaCl treatments, respectively.

Sugar beet is an industrial crop cultivated mostly for sucrose production. Today, modern hybridization applications have raised the sugar content to 20%. Considering the increased demand globally, it is required to develop new yield–increasing application strategies. This requires extensive knowledge of the genetic mechanisms to control plant growth and metabolism. Investigation of phytohormones is promising to increase our knowledge of plant growth and developmental processes. Strigolactones are recently introduced plant hormones.

Melatonin (MT) is important for plant growth and development; however, it is not known whether MT is involved in apple adventitious root (AR) development. In this study, we treated Malus prunifolia (MP) at four different stages of AR development, and analyzed the level of the endogenous hormones MT, auxin (IAA), zeatin-riboside (ZR), abscisic acid (ABA), and gibberellins (GA1+3) in all four treatment groups and the untreated control group.

Arabinogalactan-proteins (AGPs) are a class of hydroxyproline-rich proteins (HRGPs) that are heavily glycosylated (> 90%) with type II arabinogalactans (AGs). AGPs are implicated in various plant growth and development processes including cell expansion, somatic embryogenesis, root and stem growth, salt tolerance, hormone signaling, male and female gametophyte development, and defense.

An experiment was employed to identify the suitable rooting hormone and a potential hardening medium for gerbera micropropagation techniques. IBA (Indole Butyric Acid) and GA3 (Gibbrelic Acid) are taken for the study of rooting and Sand, Cocopeat, Vermicompost and Vermiculite selected alone or in combinations for the study of hardening in gerbera. Different parameters on root induction were taken similarly morphological and biochemical parameters were studies in hardend plants of gerbera.

The present crisis has emphasized human dependency on bamboo with quality planting materials. A study focused on the effect of the different concentrations of IBA (0 ppm, 100 ppm, 200 ppm, 300 ppm) on the sprouting and rooting behaviours of 5 bamboo species viz. Dendrocalamus strictus, Bambusa vulgaris, B. nutans, B. tulda and B. bambos found in coastal Odisha in order to get an idea for mass multiplication and biomass production to meet the multifarious demands of bamboo based sector.

This research carried out at the experimental station in Peza (Tirana district) has sought to test the treatment of the lignified cuttings of kiwi, cv. Hayward, with rooting hormones. Several cuttings collected were stratified until the planting period. During February, cuttings were cut 15 – 20 cm long, with a diameter of 20 mm at the base. Six bathing treatments were applied: IBA 1000 ppm and 500 ppm, AIA 1000 ppm and 500 ppm as well as Control. IBA Gel was applied at the time of planting.

In recent years, twister disease of onion has become epidemic in coastal tract and other onion growing districts of Karnataka which caused heavy loss. Survey carried out during kharif and rabi/summer 2011-12 and 2012-13 revealed typical symptoms of the disease twisting of leaf, neck with blight as well as dieback (anthracnose), scanty root system with galls and showing fungal growth was noticed. Artificial inoculations of onion seedlings with Colletotrichum gloeosporioides, Fusarium oxysporum, Meloidogyne spp. alone and in combinations expressed twister disease symptoms.

Bush pepper is a miniature black pepper (Piper nigrum L.) plant grown in the form of a bush as potted plant with decorative and economic value, raised from lateral branches (plagiotrops) of yielding vines. Growth hormones and plant growth promoting rhizomicroorganisms were evaluated for their effects on rooting of plagiotropic cuttings of black pepper.
