“…The positive correlation between ectomycorrhization and growth traits of host plants that engross numerous physical, biochemical, physiological, and molecular amendments has been attributed explicitly to the extended tertiary root system, increased absorption and transport of water by extensive extraradical ECM mycelia, facilitated acquisition of nutrients (predominantly N, C and P content), improved photosynthetic capability, production of growth regulators, phytohormone signalling, stress tolerance, attraction of other plant growth promoting microbes to ectomycorrhizosphere and stimulation of defence mechanisms 30 , 47 .…”

“…ECM fungi are most commonly isolated from fruiting bodies due to their ease of identification, and the resultant vegetative mycelia have been proved to be the most effective form of inoculum for ectomycorrhization of host plant seedlings 30 . However, the synthesis, establishment, growth, function and symbiotic alliance of ectomycorrhizal fungi is highly dependent on a range of biotic and abiotic factors and their interactions in natural as well as under laboratory conditions 28 , 29 .…”

Over the past few decades, many countries have attempted to carry out forest landscape restoration over millions of hectares of degraded land. Such efforts, however, have met with limited success because of several factors, including a lack of adequate emphasis on ectomycorrhization of the nursery seedlings. A similar scenario is seen in the Kashmir Himalaya, where the natural regeneration of degraded forests is poor despite ample restoration efforts by forest managers. To overcome this challenge, we identified two promising ectomycorrhizal species, namely Clitocybe nuda and Cortinarius distans, for their use in ectomycorrhization of seedlings of three common conifers, namely Abies pindrow, Cedrus deodara, and Picea smithiana. Laboratory studies were carried out to investigate the requirements for optimum mycelial growth of these ectomycorrhizal fungi. Best ECM mycelial growth was obtained in the basic MMN medium containing glucose as the source of carbon and nitrogen in ammonium form. C. distans showed higher growth than C. nuda across all the treatments and also proved significantly more effective in enhancing the survival and growth of the conifer host plant seedlings. The present study resulted in standardizing the requirements for mass inoculum production of the two mycobionts which could help in successful forest restoration programmes.

“…Cilas et al (1998), indican que los rasgos morfológicos, diámetro del tallo, altura de planta y número de ramas primarias, están correlacionados genéticamente con el rendimiento. Casique et al (2018), mencionan que el Dt es un indicador que revela el comportamiento de la altura y definen la producción de las plantas.…”

El café orgánico tiene una alta demanda en el mercado internacional y su cultivo se aprovecha como eje de desarrollo comunitario. En Oaxaca se implementan alternativas ecológicas de forma sostenible para la producción de café. El objetivo del estudio fue evaluar el efecto de abonos orgánicos y biofertilizantes en la dinámica del crecimiento de C. arabica L. en plantas establecidas en campo var. Typica renovadas tres años atrás. El estudio se realizó en la finca El Nueve, Santa María Huatulco, Oaxaca, durante 2018. Los abonos orgánicos evaluados fueron: Lombricomposta (L), Natur-abono® (Na), Bio-Orgamin (Bo) y guano de murciélago (Gm). Los biofertilizantes fueron a base de Azotobacter sp. (Az) y Glomus cubense (Gc). Además de sus combinaciones y un testigo (T), para un total de 17 tratamientos. Los datos se sometieron a un análisis de varianza y pruebas Tukey. Las variables evaluadas fueron altura de la planta (Ap), diámetro del tallo (Dt), índice de esbeltez (IE) y número de nudos (Nn). Los cafetos respondieron positivamente a los abonos orgánicos y biofertilizantes, obteniendo diferencias significativas entre tratamientos con un nivel de significancia (p≤ 0.05), para Ap, con la combinación de Gm+L+Gc se obtuvieron alturas de 216 cm. Para Dt, el T mostró el mayor valor con 3.16 cm. En cuanto a Nn, la combinación de Gm+L+Gc generó mayor número con 56.33 nudos. El uso de abonos orgánicos y biofertilizantes en combinación es indispensable para el buen crecimiento de los cafetos en plantaciones renovadas.

“…are two species of Mexican Pinus spp. modified in afforestation and restoration programs throughout the world, mainly because they are fast growing species and resistant to adverse environmental conditions, such as drought, shallow, eroded and poor in nutrients soils (Casique et al 2019). Molecular phylogeny studies confirm that these species are genetically similar, however, despite their similarity, the P. greggii species differs from P. patula, because it has short, erect leaves, with superior thickness and epidermal thickness, while P. patula has a higher epidermal cell width in relation to P. greggii (Singh et al 2019).…”

Seed protein profile of Pinus greggii and Pinus patula through functional genomics analysis

et al. 2020

The present work was carried out with the aim of analyzing and describing the seed proteome of Pinus patula and Pinus greggii. The analysis was performed using the "shotgun" ("gel-free") strategy. Proteins were extracted using the TCA/Phenol/Acetone protocol, subsequently separated by liquid chromatography and analyzed by mass spectrometry (nLC LTQ Orbitrap). Protein identification was performed by consulting the specific database for Pinus spp and functional classification taking into account the three functional terms (biological processes, cellular components and molecular functions) of Gene Ontology. To extract relevant Gene Ontology terms, a singular enrichment analysis (SEA) was performed, the terms were considered relevant for a minimum threshold of significance FDR < 0.05. After analyzing protein profiles, a total of 1091 proteins were identified, 362 proteins common in both species, 100 exclusives to P. greggii and 267 exclusive proteins to P. patula. The comparative analysis of the distribution of proteins as a function of the three functional terms reveals similarity between the two species. The most abundant proteins were associated with oxidationreduction processes, in terms of cellular components; in both species integral membrane proteins predominate. Regarding molecular function, the predominant expression of proteins in both species was related to ATP synthesis. The metabolic pathway with the highest participation of proteins (17 in P. greggii and 19 in P. patula) was the glycolysis/gluconeogenesis pathway. These results demonstrate that there is little genetic variability between the two species, with proteins associated with metabolic processes prior to germination prevailing.
