TCP10 acts downstream of light and retrograde signaling pathways to promote Arabidopsis cotyledon de-etiolation in concert with GLK1
Cotyledon de-etiolation is a crucial process during seedling photomorphogenesis that comprises growth pattern reprogramming and the development of photosynthetically active chloroplasts. Studying this process at the molecular level is essential to understand how plants successfully transition to autotrophic metabolism. We studied the role of...

The sunflower transcription factor HaHB11 increases soybean grain number and heat tolerance across multi-season field trials
Soybean is one of the primary sources of vegetable oil and protein worldwide; however, its yield improvement has lagged behind the other major crops. In this study we explored the potential of sunflower HaHB11, a member of the homeodomain-leucine zipper I subfamily of transcription factors, to enhance soybean yield and heat-stress tolerance. We...

Mechanical stress induces anatomical changes, tomato early flowering, and increased yield involving ethylene and auxins
Plants have evolved mechanisms to perceive and face mechanical stress (MS) caused by physical forces, including compacted soils, winds, rain, pathogens, and interactions with animals and plants. Previous research indicated that applying mechanical treatment (MT) to Arabidopsis increases both xylem area and seed yield. To explore sustainable tomato...

Study of two glycosyltransferases related to polysaccharide biosynthesis in Rhodococcus jostii RHA1
The bacterial genus Rhodococcus comprises organisms performing oleaginous behaviors under certain growth conditions and ratios of carbon and nitrogen availability. Rhodococci are outstanding producers of biofuel precursors, where lipid and glycogen metabolisms are closely related. Thus, a better understanding of rhodococcal carbon partitioning...

The chemoreceptor controlling the Wsp-like transduction pathway in Halomonas titanicae KHS3 binds and responds to purine derivatives
The chemosensory pathway HtChe2 from the marine bacterium Halomonas titanicae KHS3 controls the activity of a diguanylate cyclase. Constitutive activation of this pathway results in colony morphology alterations and an increased ability to form biofilm. Such characteristics resemble the behavior of the Wsp pathway of Pseudomonas. In this work, we...

Improved serodiagnosis of Trypanosoma vivax infections in cattle reveals high infection rates in the livestock regions of Argentina
Bovine trypanosomosis, caused by Trypanosoma vivax, currently affects cattle and has a significant economic impact in sub-Saharan Africa and South America. The development of new diagnostic antigens is essential to improve and refine existing methods. Our study evaluated the efficacy of two recombinant antigens in detecting specific antibodies in...

sincFold: end-to-end learning of short- and long-range interactions in RNA secondary structure
Motivation Coding and noncoding RNA molecules participate in many important biological processes. Noncoding RNAs fold into well-defined secondary structures to exert their functions. However, the computational prediction of the secondary structure from a raw RNA sequence is a long-standing unsolved problem, which after decades of almost...

HYL1's multiverse: A journey through miRNA biogenesis and beyond canonical and non-canonical functions of HYL1
A delicate balance in gene expression, a process highly controlled by post-transcriptional gene silencing mediated by miRNAs, is vital during plant growth and responses to stress. Within the miRNA biogenesis pathway, HYL1 is one of the most important proteins, initially recognized for its role as a cofactor of DCL1. Yet, HYL1's functions...

An atlas of the tomato epigenome reveals that KRYPTONITE shapes TAD-like boundaries through the control of H3K9ac distribution
In recent years, the exploration of genome three-dimensional (3D) conformation has yielded profound insights into the regulation of gene expression and cellular functions in both animals and plants. While animals exhibit a characteristic genome topology defined by topologically associating domains (TADs), plants display similar features with a...

Heterologous expression of coffee HB12 confers tolerance to water deficit in transgenic plants through an ABA-independent route
Drought is one of the major abiotic stresses affecting plant growth, with serious negative consequences for crop yields worldwide. Among these crops, coffee is severely injured by water deficiency. Despite its economic importance, very little is known about the molecular mechanisms governing coffee responses to water deficit. In the present work,...
