Plant tissue cultures depend entirely upon artificial light sources for illumination. The illumination should provide in the appropriate regions of electromagnetic spectrum photomorphogenic responses and photosynthetic metabolism. Controlling quality, irradiances photoperiod enables production plants with desired characteristics. Moreover, significant money savings may be achieved using both more less consuming energy lamps. In this review, attention will focused on effects characteristics plant growth regulators shoot proliferation, main process vitro propagation. balance endogenous also presented. For each spectrum, proliferation but plantlet i.e., length, fresh dry weight photosynthesis, have been analyzed. Even if a huge amount literature is available results are often conflicting. fact, lot exogenous factors, lack common protocol, make it difficult to choose most effective large number species.

Light is a fundamental environmental parameter for plant growth and development because it provides an energy source carbon fixation during photosynthesis regulates many other physiological processes through its signaling. In indoor horticultural cultivation systems, sole-source light-emitting diodes (LEDs) have shown great potential optimizing producing high-quality products. also regulator of flowering, acting on phytochromes inducing or inhibiting photoperiodic plants. Plants respond to light quality several receptors that can absorb at different wavelengths. This review summarizes recent progress in our understanding the role blue red modulation important traits, nutrient absorption assimilation, as well secondary metabolites, includes dynamic signaling networks are orchestrated by wavelengths with focus transcriptional metabolic reprogramming, productivity, nutritional Moreover, highlights future lines research should increase knowledge develop tailored recipes shape characteristics nutraceutical value

Critical Role of Regrowth Conditions in Post-Cryopreservation of In Vitro Plant Germplasm

Biology, Journal Year: 2023, Volume and Issue: 12(4), P. 542 - 542

Published: April 2, 2023

Cryopreservation is an effective option for the long-term conservation of plant genetic resources, including vegetatively propagated crops and ornamental plants, elite tree genotypes, threatened species with non-orthodox seeds or limited seed availability, as well cell root cultures useful biotechnology. With increasing success, arsenal cryopreservation methods has been developed applied to many material types. However, severe damage accumulating during multi-step procedure often causes reduced survival low regrowth, even when optimized protocol applied. The conditions at recovery stage play a vital role in supporting regrowth after and, optimized, may shift life-and-death balance toward positive outcome. In this contribution, we provide overview five main strategies available improve post-cryopreservation vitro materials their further proliferation development. particular, discuss modification medium composition (iron- ammonium-free), exogenous additives cope oxidative stress absorb toxic chemicals, modulation osmotic potential. Special attention paid growth regulators used various steps process induce desired morphological response cryopreserved tissues. Given studies on electron transport energy provision rewarmed materials, effects light-and-dark light quality. We hope that summary provides helpful guideline set references choosing have not cryopreserved. also propose step-wise be most sensitive cryopreservation-induced chemical stresses.

Comparative Analysis of Machine Learning and Evolutionary Optimization Algorithms for Precision Micropropagation of Cannabis sativa: Prediction and Validation of in vitro Shoot Growth and Development Based on the Optimization of Light and Carbohydrate Sources

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 12

Published: Oct. 21, 2021

Micropropagation techniques offer opportunity to proliferate, maintain, and study dynamic plant responses in highly controlled environments without confounding external influences, forming the basis for many biotechnological applications. With medicinal recreational interests Cannabis sativa L. growing, research related optimization of vitro practices is needed improve current methods while boosting our understanding underlying physiological processes. Unfortunately, due exorbitantly large array factors influencing tissue culture, existing approaches optimize are tedious time-consuming. Therefore, there great potential use new computational methodologies analyzing data develop improved protocols more efficiently. Here, we first tested effects light qualities using assorted combinations Red, Blue, Far White spanning 0-100 μmol/m2/s combination with sucrose concentrations ranging from 1 6% (w/v), totaling 66 treatments, on shoot growth, root development, number nodes, emergence, canopy surface area. Collected were then assessed multilayer perceptron (MLP), generalized regression neural network (GRNN), adaptive neuro-fuzzy inference system (ANFIS) model predict growth development. Based results, GRNN had better performance than MLP or ANFIS was consequently selected link different algorithms [genetic algorithm (GA), biogeography-based (BBO), interior search (ISA), symbiotic organisms (SOS)] prediction optimal levels (quality/intensity) concentration various Predictions conditions refine subsequently a validation experiment showed no significant differences between predicted optimized values observed data. Thus, this demonstrates machine learning most favorable elicit specific developmental responses. these, recommendations carbohydrate promote outcomes suggested. Ultimately, work showcases importance quality supply directing development as well power investigate complex interactions culture.

It is well-established that plants are sessile and photoautotrophic organisms rely on light throughout their entire life cycle. Light quality (spectral composition) especially important as it provides energy for photosynthesis influences signaling pathways regulate plant development in the complex process of photomorphogenesis. During previous years, significant progress has been made quality's physiological biochemical effects crops. However, understanding how modulates growth remains a challenge. In this review, we provide an overview role regulating early plants, encompassing processes such seed germination, seedling de-etiolation, establishment. These insights can be harnessed to improve production planning crop by producing high-quality seedlings factories improving theoretical framework modern agriculture.
