Tomato Biodiversity and Drought Tolerance: A Multilevel Review.

Ongoing global climate change suggests that crops will be exposed to environmental stresses that may affect their productivity, leading to possible global food shortages. Among these stresses, drought is the most important contributor to yield loss in global agriculture. Drought stress negatively affects various physiological, genetic, biochemical, and morphological characteristics of plants.

The First Latin American Consensus on Superficial and Perforating Venous Mapping.

With the aim of obtaining a map which is useful as a diagnostic tool and therapeutical orientation, complementing the written report of duplex ultrasound venous study, Latin-American Scientific Societies of Phlebology, Vascular Surgery and Vascular Imaging were invited to participate, through their regional representatives, to the First Consensus of Superficial and Perforating Venous Mapping. A consensus process using a modified Delphi method was carried out. An International Working Group was formed, which developed a Prototype of the Venous Mapping that worked as a starting point for consensus, and was presented in a first virtual meeting of 54 experts (societies' representatives) when the methodology was explained.

Small extracellular vesicles released from germinated kiwi pollen (pollensomes) present characteristics similar to mammalian exosomes and carry a plant homolog of ALIX.

Introduction: In the last decade, it has been discovered that allergen-bearing extracellular nanovesicles, termed "pollensomes", are released by pollen during germination. These extracellular vesicles (EVs) may play an important role in pollen-pistil interaction during fertilization, stabilizing the secreted bioactive molecules and allowing long-distance signaling. However, the molecular composition and the biological role of these EVs are still unclear.
