“…These precise and faster genetic crop modifications have been made with ease due to development of biotechnological approaches such as genome editing, genetic engineering and genome mapping (Munaweera et al, 2022). According to Khew et al (2022), two approaches that are gaining prominence in the fields of molecular biology and plant breeding due to their precision and efficiency include marker-assisted selection (MAS) and genome editing (GE).…”

“…The breakthroughs in genome editing like base editing, CRISPR/Cas9, CRISPR/Cpf1, dCas9 epigenetic modification, prime editing and many other transgene-free genome editing have shown great potential for improving crops (Gowda et al, 2020;Haroon et al, 2022). These improvements include the development of high-yielding cultivars with better stress tolerance and enhanced nutritional values (Khew et al, 2022). Varshney et al (2021) and Haroon et al (2022) emphasised CRISPR/Cas9 and Cpf1 are more efficient, precise and accurate and have less off-target effects when compared to other genome editing technologies.…”

Cleome gynandra: A wonder climate-smart plant for nutritional security for millions in semi-arid areas

Spider plant (Cleome gynandra) is predominantly used as a traditional leafy vegetable throughout Africa and is considered a rich natural source of essential nutrients such as vitamins, minerals and proteins. With the increase in malnutrition, diet related non-communicable diseases and poverty across the continent of Africa, the spider plant is a bona fide alternative healthy food crop to alleviate these challenges. Spider plant is an erect annual herb that could grow up to 150 cm tall, strongly branched, with a long taproot and few secondary roots. It is commonly consumed in resource-poor communities especially during times of major food scarcity. It is a drought-tolerant and resilient annual vegetable crop capable of growing well in a wide range of climatic and edaphic conditions. Despite the potential benefits and wide adaptability, progressive attempts towards the development of C. gynandra as a crop have been impeded by issues like low investment in research and development resulting in poor seed quality, relatively low yields and susceptibility to pests and diseases. In this paper, we reviewed the research that has been done regarding its morphology, growing conditions, production and utilisation (i.e., nutrition). The current review highlighted the status of the science in advancing the domestication of C. gynandra as a potential power crop for several African countries. The review concluded that with the advancement of modern biotechnology techniques and genome sequencing, there is a compelling case for investment and development in C. gynandra as a candidate for managing micronutrient deficiencies during the post-pandemic era. Finally, the existing knowledge gaps (e.g., breeding) that necessitate explorations were identified and recommendations that could enhance its development and potential commercialisation were made.

“…SSR molecular markers, commonly used in crop improvement [17], along with G-quadruplexes, important regulatory elements in gene expression [18][19][20], could potentially influence the type, distribution, and number of gene-editing sites. Among the most effective methods for integrating superior crop traits in one package are molecular breeding and gene editing [21]. SSRs, as the most frequently used molecular markers, are widely distributed in eukaryotic and prokaryotic genomes [22][23][24], with co-dominant inheritance, high polymorphism, repetitiveness, and genome coverage [25,26].…”

CRISPR/Cas9 is an efficient genome-editing tool, and the identification of editing sites and potential influences in the Camellia sinensis genome have not been investigated. In this study, bioinformatics methods were used to characterise the Camellia sinensis genome including editing sites, simple sequence repeats (SSRs), G-quadruplexes (GQ), gene density, and their relationships. A total of 248,134,838 potential editing sites were identified in the genome, and five PAM types, AGG, TGG, CGG, GGG, and NGG, were observed, of which 66,665,912 were found to be specific, and they were present in all structural elements of the genes. The characteristic region of high GC content, GQ density, and PAM density in contrast to low gene density and SSR density was identified in the chromosomes in the joint analysis, and it was associated with secondary metabolites and amino acid biosynthesis pathways. CRISPR/Cas9, as a technology to drive crop improvement, with the identified editing sites and effector elements, provides valuable tools for functional studies and molecular breeding in Camellia sinensis.

“…It is widely used for culinary purposes, especially for the growing business of pre-treatment foods, and processed foods such as fried foods, sweets and baked goods. According to the global market research of black pepper, the world production was recorded at its maximum volume at 752 thousand tons in the year 2018 with a value of 4.1 billion dollars (Khew et al, 2022). In 2020, Brazil ranked second among the largest black pepper exporters in the world, representing 15% of global trade, behind only Vietnam (41.5%).…”

Commercial substrates and their fertilization are essential for the morphophysiological, nutritional, and sanitary quality of seedlings. In this perspective, this study aimed to evaluate the quality of clonal seedlings of the black pepper cultivar Bragantina under doses of controlled-release fertilizers (CLF) in a commercial substrate. The treatments were constituted by five doses of the CLF Osmocote® 19-06-10 Mini Prill (3-4 months) (0, 2, 4, 6, and 8 kg m-3), with four replications of 16 cuttings. The CLF Osmocote®, especially in doses close to 4.16 kg m-3, showed to be promising for the production of clonal seedlings of the black pepper cultivar Bragantina.
