If you’re applying for an independent position, you’ll need to submit a Research Statement about your future research plans. Bethany Hout (@huotbethany) writes about a Pub Club group meeting to discuss how to write a Research Statment. Topics include “What makes a good research statement”, “How important is the Research Statement in the full application […]
Some bees are generalist pollinators that gather pollen from a wide range of species, whereas others are specialists that visit only one or a few species. Vanderplanck et al. examined floral traits of the host plants of two different groups of generalist bees. There was no significant correlation between bees and the floral scent, floral […]
In order to look at the origins of flowers, Moyroud et al. looked at reproductive controls in the gymnosperm Welwitschia mirabilis, which, as the authors say, is a good model because, “Although the plant body is famously bizarre, the reproductive structures are generalized.” Furthermore, its male reproductive structures are produced as soon as two years […]
Fusarium oxysporum is a fungal pathogen of plants. F. oxysporum f. sp. conglutinans (Foc) causes fungal wilt in cabbage. Two races have been identified, with Race 2 being much more pathogenic than Race 1. Li et al. used a proteomic approach to investigate the origin of Race 2’s enhanced pathogenicity. They observed 145 proteins that […]
PATHOGENESIS-RELATED 1 (PR-1) protein was identified 50 years ago as a small protein induced in response to pathogens, but its mode of action has remained obscure. PR-1 is a member of the CAP family (cysteine-rich secretory protein, antigen 5, and pathogenesis-related 1). These proteins share a 150 amino acid domain that forms an α-β-α sandwich […]
Structural biology provides a key link between genotype and phenotype. Hirano et al. probe the structure of a heterodimer of plant-specific GRAS family transcriptional regulators [SHORT-ROOT (SHR) and SCARECROW (SCR)] as bound to the transcription factor JACKDAW (JKD). The GRAS family proteins (encoded by 33 genes in Arabidopsis and 66 in rice) are involved in […]
A considerable knowledge gap remains between the plant genome and the plant metabolome. To address this, Schläpfer et al. have developed a computational pipeline to identify metabolic enzymes, pathways, and gene clusters. Although metabolic genes are known to cluster in bacteria and fungi, until recently this phenomenon was not known to be widespread in plants. […]
The classic art of plant breeding involves carefully examining a genetically segregating population for traits of interest. Increasingly, high-throughput, automated phenotyping systems are being used; for example, robots can carry plants to imaging chambers for data collection. However, growth-chamber grown plants do not fully replicate the range of conditions experienced by field-grown plants. Tanger et […]
The distribution of metabolites in tissues can be determined in situ through the technique Mass spectrometry imaging (MSI) with matrix-assisted laser desorption ionization (MALDI) (also known as MALDI-MSI). Duenas et al. used MALDI-MSI to analyze the distribution of thylakoid membrane lipids in maize, specifically comparing those of the the bundle sheath cells and mesophyll cells. […]
