Evolution of NAC transcription factors from early land plants to domesticated crops.

NAC [NO APICAL MERISTEM (NAM), ARABIDOPSIS TRANSCRIPTION ACTIVATOR FACTOR 1/2 (ATAF1/2), and CUP-SHAPED COTYLEDON (CUC2)] transcription factors are key regulators of plant growth, development, and stress responses but were also crucial players during land plant adaptation and crop domestication. Using representative members of green algae, bryophytes, lycophytes, gymnosperms, and angiosperms, we expanded the evolutionary history of NAC transcription factors to unveil the relationships among members of this gene family. We found a massive increase in the number of NAC transcription factors from green algae to lycophytes and an even larger increase in flowering plants.

Osseointegration of Implants Through Ti Biofunctionalization with Biomass from UTEX 1230 and sp. PCC 7002.

The inadequate osseointegration of titanium implants remains a significant challenge in orthopedics, limiting the long-term efficacy of prostheses and medical devices. It has been determined that biological aging of the titanium surface compromises the implant-bone tissue interaction due to increased hydrophobicity and accumulation of organic molecules. To address this issue, an innovative strategy has been proposed: the biofunctionalization of Ti6Al4V surfaces utilizing biomass derived from UTEX 1230 and sp.

Association between bacterial community and cadmium distribution across Colombian cacao crops.

Unlabelled: Assessing the bacterial community composition across cacao crops is important to understand its potential role as a modulator of cadmium (Cd) translocation to plant tissues under field conditions; Cd mobility between soil and plants is a complex and multifactorial problem that cannot be captured only by experimentation. Although microbes have been shown to metabolize and drive the speciation of Cd under controlled conditions, regardless of the link between soil bacterial community (SBC) dynamics and Cd mobilization in the rhizosphere, only a few studies have addressed the relationship between soil bacterial community composition (SBCC) and Cd content in cacao seeds (Cd). Therefore, this study aimed to explore the association between SBCC and different factors influencing the distribution of Cd across cacao crop systems.

The gut metabolome in a cohort of pregnant and lactating women from Antioquia-Colombia.

Nutrition during the perinatal period is an essential component of health and one that can severely impact the correct development of a human being and its overall condition, in all the subsequent stages of life. The availability of several compounds, mainly macronutrients and micronutrients, plays a key role in the balanced nutrition of both mother and baby and is a process with direct relation to the gut microbiome. Thus, we hereby refer to the set of small molecules derived from gut microbiome metabolism as the gut metabolome.

Advances in the Development of Biofertilizers and Biostimulants from Microalgae.

Microalgae have commercial potential in different sectors of the industry. Specifically in modern agriculture, they can be used because they have the ability to supply nutrients to the soil and produce plant growth hormones, polysaccharides, antimicrobial compounds, and other metabolites that improve agricultural productivity. Therefore, products formulated from microalgae as biofertilizers and biostimulants turn out to be beneficial for agriculture and are positioned as a novel and environmentally friendly strategy.

The ABC of mobility.

The use of cars in cities has many negative impacts, including pollution, noise and the use of space. Yet, detecting factors that reduce the use of cars is a serious challenge, particularly across different regions. Here, we model the use of various modes of transport in a city by aggregating Active mobility (A), Public Transport (B) and Cars (C), expressing the modal share of a city by its ABC triplet.
