Like many cinephiles, I spend a lot of time with DVDs and Blu-rays, fair amount that releases from the Criterion Collection, not only important contributor to eve...

We sought evidence for the occurrence and seasonal variation of indole-3-acetic acid (IAA) in shoots of Douglas fir (Pseudotsuga menziesii [Mirb.] Franco).Collections obtained in December and June were extracted with methanol and diethyl ether. Extracts were purified by solvent partitioning and with Sephadex LH-20. Qualitative and quantitative information was acquired by gas-liquid chromatograp...

Natural history collections contain data that are critical for many scientific endeavors. Recent efforts in mass digitization are generating large datasets from these collections that can provide unprecedented insight. Here, we present examples of how deep convolutional neural networks can be applied in analyses of imaged herbarium specimens. We first demonstrate that a convolutional neural net...

Forward genetic screens enable the unbiased identification of genes involved in biological processes. In Arabidopsis, several mutant collections are publicly available, which greatly facilitates such practice. Most of these collections were generated by agrotransformation of a T-DNA at random sites in the plant genome. However, precise mapping of T-DNA insertion sites in mutants isolated from s...

Expressed sequence tags (ESTs) from fungal-infected plant tissues are composed of a mixture of plant and fungal sequences. Using freely available software and tools, a novel procedure is described for distinguishing plant and fungal DNA sequences. Although the GenBank non-redundant (NR) database is larger and therefore one would presume that BLASTX analysis of it would be more accurate, superio...

Eleven species of marine Chaetoceros Ehrenberg newly recorded from Bangladesh have been illustrated and described in the present paper. The are: aequatorialis Cleve, C. constrictus Gran, decipiens denicus didymus Ehrenberg, diversus pelagicus pendulus Karsten, pseudobrevis Pavillard, seychellarus G.H.H. Karsten tetrastichon Cleve. All these here with citation relevant references collections exa...

Background and aims: Botanic gardens play a fundamental role in conservation due to the maintenance of seed live plant collections. However, exchange ornamental seeds between botanic can facilitate entry alien species with invasive potential. In 2018, during visit collections National Botanical Garden (Chile), we discovered populations an herb genus Veronica (Plantaginaceae). The aim this paper...

SOMEONE SHOULD INFORM RUSSIAN President Vladimir Putin, who is seeking to displace scientists and germ plasm at the Vavilov Institute of Plant Industry so federal bureaucrats can move into the space (“Prestigious plant institute in jeopardy,” News of the Week, 31 Jan., p. 641), that 61 years ago, several Vavilov scientists sacrificed their lives in a truly heroic, unprecedented, and ultimately ...
