The objective of this study was to investigate the effect of weeds and fertilizer application on dry bean seed quality. Four dry bean (Phaseolus vulgaris L.) cultivars, Caledon (C), Ukulinga (U), Gadra (G) and uMtata (M) were planted for seed production using a field experiment designed as a split, replicated three times. There were three levels of weeding W0 (no weeding), W1 (weeding until 50% flowering) and W2 (weeding all the time until harvest). The weeding treatments were split into no fertilizer application (F0) and optimum fertilizer application (F1) according to soil fertility analysis. At harvest maturity, seeds were compared for quality with respect to size, germination and total protein content. Proline content was determined as a measure of crop response to the weed and fertilizer stresses during crop production. Although seed size was affected by management stress, seed germination was not significantly affected by weeding and fertilizer even when it was explored in terms of seed vigor by determining rate of germination and seedling size. However, weed management and fertilizer application significantly affected proline and total crude protein contents in seeds (P < 0.05). The findings of this study show that the biotic stress of weeds and abiotic stress of soil fertility can be used to determine seed physiological quality of dry bean seeds.

“…When explants were cut, DEGs related to alanine, aspartate and glutamate, β-alanine, and histidine metabolism were up-regulated, which could result in increased production of glutamate and aspartate, and the signaling amino acid, γ-aminobutyric acid (GABA). GABA, like JA, plays a signaling role in response to stress and in growth and development (González-Gallegos et al 2015;Ramesh et al 2017). Up-regulation of DEGs related to glycine, serine and threonine metabolism affects tryptophan metabolism, just like the up-regulation of DEGs related to phenyalanine, tryptophan and tyrosine biosynthesis at several points within the pathway (Table 2).…”

The explant is an important parameter in plant tissue culture. Most plant tissue culture studies in the literature have focused almost exclusively on the use of explants as a tool for organogenesis or (micro)propagation, and there is limited information that documents the changes that occur in explants in response to cutting during explant preparation just prior to or during culture. To better understand the molecular changes occurring during the wounding process that accompanies the preparation of an explant, this study examined the mRNA transcription profile of 4-week-old potato (Solanum tuberosum L. cv. Desirée) single-node stem segments. To achieve this, RNA-seq analysis was performed to identify significantly differentially expressed genes (DEGs) that existed between uncut in vitro plantlets and cut explants. DEGs corresponding to specific enzyme profiles were broadly connected to cellular processes in the extracellular region, nucleus, and plasma membrane, and were associated with biosynthesis, carbohydrate metabolism and catabolism, cellular protein modification, growth and development, and response to stress. The RNA-seq data of eight highly up-or down-regulated DEGs was validated by RT-qPCR, showing high positive Spearman and Pearson correlation coefficients (0.73 and 0.95, respectively) between SeqMonk LFC and RT-qPCR LFC. These results provide a novel perspective of the changes taking place within explants when they are cut and serve as a valuable basis for the study of explant-related stress in plant tissue culture in other species. In addition, our findings may contribute to an understanding of the success or failure of the tissue culture protocol and subsequent establishment of in vitro cultures by better appreciating the stress-related molecular changes taking place. Key message mRNA transcription profiles were used to show how differentially expressed genes in cut stem explants of potato during preparation for plant tissue culture constitutes an abiotic stress, although not fatal.

Bacterias endófitas y su efecto en la inducción de resistencia sistémica en el cultivo de frijol contra Rhizoctonia solani y Fusarium oxysporum

El cultivo del frijol es afectado por diversas enfermedades en las que destaca la marchitez causada por Rhizoctonia solani y Fusarium spp. El manejo de estos patógenos principalmente se realiza mediante el uso de compuestos químicos los cuales contaminan el ambiente, son tóxicos para el humano, desarrollan resistencia en los fitopatógenos y además aumentan los costos de producción. El objetivo del presente estudio fue evaluar la respuesta de inducción de resistencia mediante la inoculación de bacterias endófitas contra R. solani y F. oxysporum. Se utilizaron plantas de frijol de 45 días de edad para determinar la concentración de proteínas (PR) y la actividad de peroxidasa (POD), fenilalanina amonio liasa (PAL) a las 6, 12, y 24 h después de la inoculación de los consorcios. Los resultados evidenciaron que los microorganismos endofíticos promueven los mecanismos de defensa en frijol, pudiendo propiciar resistencia contra F. oxysporum y R. solani.
