Anti-Prostate Cancer Properties of Anthocyanidins/Anthocyanins
As water-soluble flavonoid derivatives, anthocyanidins and anthocyanins are the plants pigments mostly rich in berries, pomegranate, grapes, and dark color fruits. Many bioactivity properties of these advantageous phytochemicals have been reported; among them, their significant abilities in the suppression of tumor cells are of the promising therapeutic features, which have recently attracted great attention. The prostate malignancy, is considered the 2nd fatal and the most distributed cancer type in men worldwide.  In general, the anthocyanins (especifically cyanidin-3-O-glucoside) indicated higher activity against prostatic neoplasms compared to their correlated anthocyanidins (e.g., delphinidin); in which potent anti-inflammatory, apoptosis, and anti-proliferative activities were analyzed.

Bacopa monnieri (L.) Wettst.
Bacopa monnieri has been used as a reputed drug in the Indian traditional ayurvedic system for centuries. This medicinal herb with important phytopharmaceuticals has been popularly known as “Brahmi”. In recent years, B. monnieri has been extensively studied for its bioactive constituents, constituents responsible for memory enhancing effect, and also its diverse other useful effects. It possesses many pharmacological activities such as antioxidant, gastrointestinal, endocrine, antimicrobial, anti-inflammatory etc. The plant has been also used for the treatment of neurological and neuropsychiatric diseases. Due to its multipurpose therapeutic potential, micropropagation using axillary meristems and de novo organogenesis has been extensively studied in the species and is being reviewed. High frequency direct shoot organogenesis can be induced in excised leaf and internode explants in the absence of exogenous phytohormones and the rate of induction is enhanced in the presence of exogenous cytokinins, supplements, growth regulators, etc. Using explants from tissue culture raised plants, direct shoot regeneration leading to production of more than 100 rooted plants/explant within 8–12 weeks period with 85%–100% survival in the field after acclimatization can be expected following optimized protocols. Bioreactor based micropropagation was found to increase the multiplication rate of shoot cultures for the commercial propagation of B. monnieri plants. The maximum content of bacosides has been recorded in shoot biomass using an airlift bioreactor system. Further studies for the biosynthesis of bacosides and other secondary metabolites need to be conducted in the species utilizing untransformed shoot cultures in bioreactors.

Atriplex Portulacoides as Functional Food
The halophyte Atriplex portulacoides (syn. Halimione portulacoides) occurs in habitats that are exposed to seawater inundations, and shows biochemical adaptations to saline and oxidative stresses. Its composition includes long chain lipids, sterols, phenolic compounds, glutathione, carotenoids,and micronutrients such as Fe, Zn, Co and Cu. The productivity of A. portulacoides in natural environments, and its adaptability to non-saline soils, make it a potential crop of high economic interest. This plant is suitable to be exploited as a functional food that is potentially able to reduce oxidative stress and inflammatory processes in humans and animals. This plant offers a valuable example of valorisation of the biodiversity for promoting the sustainability and diversification in agriculture.

Conservation of Crop Genetic Resources
The conservation of crop genetic resources, including their wild relatives, is of utmost importance for the future of mankind. Most crops produce orthodox seeds and can, therefore, be stored in seed genebanks. However, this is not an option for crops and species that produce recalcitrant (non-storable) seeds such as cacao, coffee and avocado, for crops that do not produce seeds at all; therefore, they are inevitably vegetatively propagated such as bananas, or crops that are predominantly clonally propagated as their seeds are not true to type, such as potato, cassava and many fruit trees. Field, in vitro and cryopreserved collections provide an alternative in such cases.

Diaporthe citri
Citrus melanose is a fungal disease caused by Diaporthe citri F.A. Wolf. It is found in various citrus-growing locations across the world. The host range of D. citri is limited to plants of the Citrus genus. The most economically important hosts are Citrus reticulata (mandarin), C. sinensis (sweet orange), C. grandis or C. maxima (pumelo), and C. paradisi (grapefruit). In the life cycle of D. citri throughout the citrus growing season, pycnidia can be seen in abundance on dead branches, especially after rain, with conidia appearing as slimy masses discharged from the dead twigs. Raindrops can transmit conidia to leaves, twigs, and fruits, resulting in disease dispersion throughout small distances. Persistent rains and warm climatic conditions generally favor disease onset and development. The melanose disease causes a decline in fruit quality, which lowers the value of fruits during marketing and exportation. High rainfall areas should avoid planting susceptible varieties.

Plant-Derived Pesticides
Pests and diseases are responsible for most of the losses related to agricultural crops, either in the field or in storage. Moreover, due to indiscriminate use of synthetic pesticides over the years, several issues have come along, such as pest resistance and contamination of important planet sources, such as water, air and soil. Therefore, in order to improve efficiency of crop production and reduce food crisis in a sustainable manner, while preserving consumer’s health, plant-derived pesticides may be a green alternative to synthetic ones.

Endophytic Bacterial in Rice Plant
Endophytic bacterial communities are beneficial communities for host plants that exist inside the surfaces of plant tissues, and their application improves plant growth. They benefit directly from the host plant by enhancing the nutrient amount of the plant’s intake and influencing the phytohormones, which are responsible for growth promotion and stress. Endophytic bacteria play an important role in plant-growth promotion (PGP) by regulating the indirect mechanism targeting pest and pathogens through hydrolytic enzymes, antibiotics, biocontrol potential, and nutrient restriction for pathogens.

Taxa of the Genus Iris
Some wild, morphologically diverse taxa of the genus Iris L. in the broad Alpine-Dinaric area have never been explored molecularly, and/or have ambiguous systematic status. The main aims of our research were to perform a molecular study of critical Iris taxa from that area (especially a narrow endemic species I. adriatica, for which we also analysed genome size) and to explore the contribution of eight microsatellites and highly variable chloroplast DNA (ndhJ, rpoC1) markers to the understanding of the Iris taxa taxonomy and phylogeny.

Alpha-Emitting Radionuclides in Wild Mushrooms
Alpha-emitting radioisotopes are the most radiotoxic nuclides among all radionuclides. Especially medium- and long-living isotopes that enter the body, are hazardous metals of the greatest importance from the human life point of view. This review focuses on the most common natural and anthropogenic origin alpha-emitting radionuclides in wild mushrooms around the world. Mushrooms are considered as suitable bioindicators of environmental pollution with some metallic elements, for the reason they bioaccumulate a range of mineral ionic constituents including radioactive elements at different levels. Various species have different retain capacities of individual radionuclides. In turn, wild edible mushrooms are food products, mostly consumed regionally and also traded at an international scale. Mushrooms under pollution events situation might cause a risk to consumers due to exposure to highly radiotoxic decay particles produced by alpha emitters.

Zinc and Selenium Mitigate Abiotic Stresses in Plants
Abiotic stress factors are considered a serious threat to various growth parameters of crop plants. Stressors such as drought, salinity, and heavy metals (HMs) hamper the chlorophyll content in plants, resulting in low photosynthesis, hinder the integrity of cell membranes, reduce biomass, and overall growth and development of crops which ultimately results in the sharp decline of crop yield. Under such stressful conditions, various strategies are employed to overcome hazardous effects. Application of Zinc (Zn) or Selenium (Se) in different forms is an effective way to alleviate the abiotic stresses in plants. Zn and Se play a pivotal role in enhancing the chlorophyll level to improve photosynthesis, reducing oxidative stress by limiting reactive oxygen species (ROS) production, controlling HMs absorption by plant roots and their accumulation in the plant body, maintaining homeostasis, and alleviating all the detrimental effects caused by abiotic stress factors.

Barley
Barley (Hordeum vulgare) has been widely used as a model crop for studying molecularand physiological processes such as chloroplast development and photosynthesis. During thesecond half of the 20th century, mutants such as albostrians led to the discovery of thenuclear-encoded, plastid-localized RNA polymerase and the retrograde (chloroplast-to-nucleus)signalling communication pathway, while chlorina-f2 and xantha mutants helped to shed light onthe chlorophyll biosynthetic pathway, on the light-harvesting proteins and on the organization ofthe photosynthetic apparatus. However, during the last 30 years, a large fraction of chloroplastresearch has switched to the more “user-friendly” model species Arabidopsis thaliana, the firstplant species whose genome was sequenced and published at the end of 2000. Despite its manyadvantages, Arabidopsis has some important limitations compared to barley, including the lackof a real canopy and the absence of the proplastid-to-chloroplast developmental gradient acrossthe leaf blade. These features, together with the availability of large collections of natural geneticdiversity and mutant populations for barley, a complete genome assembly and protocols for genetictransformation and gene editing, have relaunched barley as an ideal model species for chloroplastresearch. In this review, we provide an update on the genomics tools now available for barley, andreview the biotechnological strategies reported to increase photosynthesis eciency in model species,which deserve to be validated in barley.

Nucleosides and Nucleotides
Nucleotides fulfill many essential functions in plants. Compared to non-plant systems, these hydrophilic metabolites have not been adequately investigated in plants, especially the less abundant nucleotide species such as deoxyribonucleotides and modified or damaged nucleotides. Until recently, this was mainly due to a lack of adequate methods for in-depth analysis of nucleotides and nucleosides in plants.
