“…This diversification is also reflected by the important structural variations found within the Aux/IAA proteins. This partially accounts for the Aux/-IAA conservation in these species during the evolutionary process ( [25,39,64,65]. Twelve of the 25 FtAux/IAA loci formed six sister pairs in the NJ reconstructions, four of which had strong bootstrap support, indicating that Aux/-IAA genes in Tartary buckwheat may play nonredundant roles during plant development.…”

Auxin/indoleacetic acid (Aux/IAA) family genes respond to the hormone auxin, which have been implicated in the regulation of multiple biological processes. In this study, all 25 Aux/IAA family genes were identified in Tartary buckwheat (Fagopyrum tataricum) by a reiterative database search and manual annotation. Our study provided comprehensive information of Aux/IAA family genes in buckwheat, including gene structures, chromosome locations, phylogenetic relationships, and expression patterns. Aux/IAA family genes were nonuniformly distributed in the buckwheat chromosomes and divided into seven groups by phylogenetic analysis. Aux/IAA family genes maintained a certain correlation and a certain species-specificity through evolutionary analysis with Arabidopsis and other grain crops. In addition, all Aux/IAA genes showed a complex response pattern under treatment of indole-3-acetic acid (IAA). These results provide valuable reference information for dissecting function and molecular mechanism of Aux/IAA family genes in buckwheat.

“…In our results, both the IAA and tZR contents in corms increased significantly during the second leaf sprouting period. Moreover, the genes encoding the family of auxin efflux carriers, such as PINs , tent to be highly expressed during the same period, which would facilitate efficient and directional auxin export out of the cell and promote the polar auxin transport stream, precluding upward movement into the axillary buds ( Forestan and Varotto, 2012 ; Huang et al., 2020 ). This may allow cytokinins in corms to directly promote bud outgrowth.…”

Amorphophallus muelleri has a multileaf growth pattern different from that of other konjacs; however, the hormonal mechanism underlying this phenomenon is not clear. In this study, the levels of hormones closely related to the sprouting of the axillary bud, including five types of cytokinins, indole-3-acetic acid (IAA) and abscisic acid (ABA) were measured. In the second leaf sprouting stage, the content of trans-zeatin riboside (tZR) in corms increased more than 5000-fold over that in the dormancy period. Surprisingly, although the expression of CYP735A1 and CYP735A2, which synthesize the precursors for tZR was elevated at the second leaf sprouting stage, the expression of IPTs, which have key roles in cytokinin biosynthesis, did not change significantly. In addition, most cytokinin contents in leaves during the same period were significantly lower than those in corms. We speculate that the high cytokinin contents in the corms may not biosynthesized de novo in corms. In addition, the IAA content in the corms also considerably increased during the second leaf sprouting stage. Indole-3-acetaldehyde oxidase (AO1) and auxin efflux carrier PIN1A, presented relatively high expression levels in the same period. In contrast, ABA content, and the expression of NCED1, a rate-limiting enzyme in ABA biosynthesis, were suppressed at the second leaf sprouting stage. It is worth mentioning that N6-(Δ2-isopentenyl) adenosine (iP)-type cytokinins have a high content in corms in the dormant period that significantly decreases after the first leaf sprouting stage, which is completely different from the trend of tZR. By treating dormant corms with iP, the percentage of multibud plants increased, and the growth performance in terms of bud and root length was significantly higher than those of the control. This implies that iP-type cytokinins tend to play a role in promoting first seedling sprouting. Furthermore, there was a remarkable increase of the IAA content in both corms and roots under iP treatment but an inhibitory effect in buds. We speculate that the increase in the IAA content induced by iP is tissue specific. These results will assist in the understanding of the role of hormones, especially cytokinins, in the multileaf growth type of konjac.

Introducción: El café es uno de los cultivos más importantes mundialmente, posicionándose en el segundo lugar después del petróleo crudo. A partir de 1850, el café se comenzó a expandir con la promoción de los colonos europeos. El café representa una actividad económica importante en Centroamérica, representando alrededor del 10% de la producción mundial. Métodos: Se realizó una revisión bibliográfica que se centró en identificar información relacionada con el cultivo de café. Desarrollo: Se cree que Etiopía es el lugar de nacimiento original del café. Hay dos especies principales del cultivo de café: Arabica y Robusta. La filogenia molecular de las especies de café se basa en 28,800 polimorfismos de nucleótido unido definiendo relaciones entre las especies. Por otro lado, la producción de café ha sido un pilar fundamental para la economía de Honduras, posicionándose como el mayor exportador de café de Centroamérica y el quinto en el mundo. Conclusión: Por la importancia del café en el mundo y en Honduras, es importante destacar el papel de la biotecnología en el desarrollo de variedades resistentes a diferentes plagas y enfermedades, garantizando una producción sostenible del cultivo.
