ATP-binding cassette (ABC) transporter genes act as transporters for different molecules across biological membranes and are involved in a diverse range of biological processes. In this study, we performed a genome-wide identification and expression analysis of genes encoding ABC transporter proteins in three Capsicum species, i.e., Capsicum annuum , Capsicum baccatum and Capsicum chinense . Capsicum is a valuable horticultural crop worldwide as an important constituent of many foods while containing several medicinal compounds including capsaicin and dihydrocapsaicin. Our results identified the presence of a total of 200, 185 and 187 ABC transporter genes in C . annuum , C . baccatum and C . chinense genomes, respectively. Capsaicin and dihydrocapsaicin content were determined in green pepper fruits (16 dpa). Additionally, we conducted different bioinformatics analyses including ABC genes classification, gene chromosomal location, Cis elements, conserved motifs identification and gene ontology classification, as well as profile expression of selected genes. Based on phylogenetic analysis and domain organization, the Capsicum ABC gene family was grouped into eight subfamilies. Among them, members within the ABCG, ABCB and ABCC subfamilies were the most abundant, while ABCD and ABCE subfamilies were less abundant throughout all species. ABC members within the same subfamily showed similar motif composition. Furthermore, common cis -elements involved in the transcriptional regulation were also identified in the promoter regions of all Capsicum ABC genes. Gene expression data from RNAseq and reverse transcription-semi-quantitative PCR analysis revealed development-specific stage expression profiles in placenta tissues. It suggests that ABC transporters, specifically the ABCC and ABCG subfamilies, may be playing important roles in the transport of secondary metabolites such as capsaicin and dihydrocapsaicin to the placenta vacuoles, effecting on their content in pepper fruits. Our results provide a more comprehensive understanding of ABC transporter gene family in different Capsicum species while allowing the identification of important candidate genes related to capsaicin content for subsequent functional validation.

“…Potassium fertilizer plays a major role in plant physiological process. It was reported [40] that fruit weight and fruits size increase with an increase in potassium fertilizer. Potassium has been noted to improve fruits quality by increasing the total sugar and total soluble solids in fruits [41].…”

Background: The optimum rate of nutrient must be defined with reference to soil properties for individual crops and soil. Objective: Field experiments were carried out in 2015 and 2016 cropping seasons to determine the various levels (0, 40, 80, 120 and 160 kg ha-1) of potassium fertilizer (muriate of potash , KCl), on soil chemical properties, leaf nutrient contents, performance and proximate quality of sweet potatoes (Ipomoea batatas L.). Method: The five treatments were arranged in a randomized complete block design with three replicates. Results: Studies showed that K fertilizer in both the years significantly influenced N, P and K concentrations compared with the control and also increased the soil concentrations of these nutrients from 0 - 160 kg ha-1 K fertilizer. However, soil K only increased up to 80 kg ha-1 fertilizer after which there was a decrease. There was a reduction in the values of Ca and Mg in the soil as the levels of K increased. Leaf nutrient concentration of the sweet potato was consistent with the values of soil chemical properties recorded. 80 kg ha-1 K fertilizer was observed to be the highest value of sweet potato growth and tuber yield after which there was a reduction. The yield decrease was adduced to excessive K application leading to imbalanced sweet potato plant nutrition compared with N, P, Ca and Mg. K fertilizer significantly influenced moisture, vitamin C and carbohydrate compared with the control. The highest values of fibre and protein were obtained at 80 and 40 kg ha-1 K fertilizer, respectively. Dry matter and fat contents of the sweet potato reduced by K application from 0 - 160 kg ha-1 application rate. Conclusion: For best tuber yield, quality and economic response of K fertilizer to the sweet potato in the agro-ecological zone or in other similar soil conditions elsewhere in the tropics could be achieved by applying 80 kg ha-1 K fertilizer.

“…Additionally, K is involved in post-harvest quality of vegetables and fruits; it is associated with quality in products with a plant origin because of its important effects on post-harvest attributes, such as color, size, acidity, resistance to transportation, handling, storage, nutritional value, and industrial qualities (Javaria et al, 2012). Woldemariam et al (2018) assessed the effect of potassium levels (0,50,100,150,200,250,300,350 and 400 kg ha -1 of K 2 O) on productivity and fruit quality in tomatoes.

Genotype-environment interactions (GEI) were assessed in 10 cherry tomato accessions in nine environments, including four artificial settings (0, 60 120, and 180 kg ha-1 of potassium) established on the experimental farms Montelindo (Palestina), Tesorito (Manizales), and CEUNP (Palmira) (Colombia). The plant material included 10 cherry tomato genotypes obtained from the germplasm bank at the Instituto Agronómico de Campinas and Tomato Genetics Resources Center (TGRC). A completely randomized block design with four blocks corresponding to the level of potassium fertilization was used (0, 60, 120, 180 kg ha-1); 0 kg ha-1 was the level reported for the soil. The effective size of the experiment unit was seven plants; the plot included the five central plants. A distance of 1.5 m between rows, 0.50 m between plants, and 2 m between blocks was used. The contents of soluble solids (°Brix), vitamin C (mg/100 g fresh weight), and lycopene (µg g-1 fresh weight) were assessed. The analysis of variance (ANOVA) showed significant differences (P<0.01) between the tomato genotypes, environments, and G×E interactions for the three assessed traits . The AMMI analysis identified similar and contrasting environments and determined the genotypes that contributed the most to the GEI. The environments with 120 and 180 kg ha-1 potassium favored the expression of vitamin C, while Palmira favored the lycopene content. The findings are useful for identifying optimal locations and elite genotypes that can be used as sources of variability in fruit quality improvement programs for cherry tomatoes.
