“…Their exclusive presence in the native soil may be associated with their ability to improve the expression levels of nutrient transporter genes in fungal absorptive hyphae to increase mineral nutrients availability and translocation to the host plant 84 , thereby contributing to nutrient cycling in the undisturbed native soils 85 . These characteristics may ultimately affect seedling emergence, root development, and plant performance under (un) favorable conditions 86 . AMF facilitate seedlings establishment by enabling them to get access to limiting nutrients 87 .…”

In the current study, an eco-friendly management technology to improve young carob (Ceratonia siliqua L.) tree tolerance to water deficit was set up by using single or combined treatments of arbuscular mycorrhizal fungi (AMF) and/or compost (C). Two groups of young carob have been installed: (i) carob cultivated under well-watered conditions (WW; 70% field capacity (FC)) and (ii) where the plants were drought-stressed (DS; 35% FC) during 2, 4, 6, and 8 months. The effect of used biofertilizers on the course of growth, physiological (photosynthetic traits, water status, osmolytes, and mineral content), and biochemical (hydrogen peroxide (H2O2), oxidative damage to lipids (malondialdehyde (MDA), and membrane stability (MS)) traits in response to short- and long-term droughts were assessed. The dual application of AMF and C (C + AMF) boosted growth, physiological and biochemical parameters, and nutrient uptake in carob under WW and DS. After eight months, C + AMF significantly enhanced stomatal conductance by 20%, maximum photochemical efficiency of PSII by 7%, leaf water potential by 23%, chlorophyll and carotenoid by 40%, plant uptake of mineral nutrients (P by 75%, N by 46%, K+ by 35%, and Ca2+ by 40%), concentrations of soluble sugar by 40%, and protein content by 44% than controls under DS conditions. Notably, C + AMF reduced the accumulation of H2O2 and MDA content to a greater degree and increased MS. In contrast, enzyme activities (superoxide dismutase, catalase, peroxidase, and polyphenoloxidase) significantly increased in C + AMF plants under DS. Overall, our findings suggest that the pairing of C + AMF can mediate superior drought tolerance in young carob trees by increasing leaf stomatal conductance, cellular water content, higher solute concentration, and defense response against oxidative damage during the prolonged period of DS.

“…S4). Seedlings are exposed to various biotic and abiotic stresses that pose serious risks to the plants growing near the soil surface ( 40 , 41 ). Therefore, ATAF1, a regulator with dual functions in morphogenesis and stress responses, may help ensure the smooth transition of seedlings from rapid hypocotyl growth in the dark to slower photomorphogenetic growth while also protecting them from stresses.…”

The opening of the embryonic leaves (cotyledons) as seedlings emerge from the dark soil into the light is crucial to ensure the survival of the plant. Seedlings that sprout in the dark elongate rapidly to reach light but keep their cotyledons closed. During de-etiolation, the transition from dark to light growth, elongation slows and the cotyledons open. Here, we report that the transcription factor ACTIVATING FACTOR1 (ATAF1) participates in de-etiolation and facilitates light-induced cotyledon opening. The transition from dark to light rapidly induced ATAF1 expression and ATAF1 accumulation in cotyledons. Seedlings lacking or overexpressing ATAF1 exhibited reduced or enhanced cotyledon opening, respectively, and transcriptomic analysis indicated that ATAF1 repressed the expression of genes associated with growth and cotyledon closure. The activation of the photoreceptor phytochrome A (phyA) by far-red light induced its association with the ATAF1 promoter and stimulation of ATAF1 expression. The transcription factor ELONGATED HYPOCOTYL5 (HY5), which is also activated in response far-red light, cooperated with phyA to induce ATAF1 expression. ATAF1 and HY5 interacted with one another and cooperatively repressed the expression of growth-promoting and cotyledon closure genes. Together, our study reveals a mechanism through which far-red light promotes cotyledon opening.

“…En general los inóculos CM-LEY y CM-SJ fueron los más influyentes, superando a CM-Conila; con efectos paralelos a humus de lombriz que superó a gallinaza; en cuanto al ambiente, las quina en invernadero obtuvo la mayor velocidad de crecimiento. Los hallazgos, demuestran que, resulta factible el uso de HMA autóctonos en la propagación de quina y su principal beneficio para las plantas es la fijación y translocación de nutrientes, especialmente de fósforo y otros elementos indisponibles, así mismo, transportan agua aun cuando las condiciones sean adversas para las plantas, favoreciendo el correcto crecimiento y desarrollo de las mismas (Dalling et al, 2011;Huang et al, 2018;Pankaj et al, 2021).…”

El estudio tuvo por objetivo evaluar el efecto de micorrizas arbusculares y abonos orgánicos en el comportamiento vegetativo de Cinchona officinalis en ambientes controlados. La investigación se instaló bajo un diseño completo al azar con arreglo trifactorial (4A: micorrizas x 3B: abonos x 2C: ambientes), contando con 72 unidades experimentales. Las plantas de quina fueron inoculadas en vivero e invernadero con 40 g de micorrizas procedentes de bosques naturales (San Jerónimo, Conila y Leymebamba) y abonadas con 40 g de gallinaza y humus de lombriz. Se encontró que la mortalidad de la quina se dio en el vivero y abonadas con gallinaza, con un 6.3 % en promedio, por su parte, no se reportó mortalidad a nivel de invernadero; respecto a la velocidad de crecimiento, los consorcios micorrízicos SJ y LEY tuvieron mayor efecto, juntamente con la aplicación de humus de lombriz a nivel de invernadero. Se concluye que, resulta factible propagar la quina, inoculando con micorrizas arbusculares autóctonas, potenciando su efectividad en complemento con humus de lombriz, pudiéndose usar como sustrato alternativo y sustituir a la turba de bosque; paralelamente, es indispensable manejar condiciones ambientales (temperatura y humedad relativa), para lograr una alta supervivencia y alta velocidad de crecimiento.
