The miR319-based repression of SlTCP2/LANCEOLATE activity is required for regulating tomato fruit shape.

Fruit morphogenesis is determined by the coordination of cell division and expansion, which are fundamental processes required for the development of all plant organs. Here, we show that the regulation of TEOSINTE BRANCHED1/CYCLOIDEA/PCF (TCP) LANCEOLATE (TCP2/LA) by miR319 is crucial for tomato fruit morphology. The loss of miR319 regulation in the semi-dominant La mutant led to a premature SlTCP2/LA expression during gynoecium patterning, which results in modified cell division during carpel development.

Short-term results of unroofing and marsupialization compared to the Karydakis technique in the treatment of pilonidal sinus. A randomized prospective study.

Introduction: The treatment of pilonidal sinus (PS) is usually surgical, but no procedure is considered the gold standard. The Karydakis (K) technique is widely used, and unroofing and marsupialization (UM) is a simple surgery with good results.

Primary Objective: To evaluate early postoperative complications (EPC) 30 days after UM surgery compared to the K technique.

The biogeography of the Amazonian tree flora.

We describe the geographical variation in tree species composition across Amazonian forests and show how environmental conditions are associated with species turnover. Our analyses are based on 2023 forest inventory plots (1 ha) that provide abundance data for a total of 5188 tree species. Within-plot species composition reflected both local environmental conditions (especially soil nutrients and hydrology) and geographical regions.

CONSTANS alters the circadian clock in Arabidopsis thaliana.

Plants are sessile organisms that have acquired highly plastic developmental strategies to adapt to the environment. Among these processes, the floral transition is essential to ensure reproductive success and is finely regulated by several internal and external genetic networks. The photoperiodic pathway, which controls plant response to day length, is one of the most important pathways controlling flowering.
