Protecting plants from extinction has become a bit easier in Colorado due to a change in drug laws, and other stories we’ve shared recently.

Plant Survey Reveals Alarming Presence of Nonnative Invasive Species in Southwest Ohio

A recent plant survey conducted by researchers from University of Cincinnati and the Cincinnati Museum Center has revealed that dozens of nonnative invasive plant species are thriving in southwest Ohio, posing a serious threat to the native biodiversity and economy of the region.

Christmas Trees Specially Bred by Geneticists May Eliminate Seasonal Chore

Geneticists are working to engineer Christmas trees that result in a lot less vacuuming for you at home.

Hard data: looking deep into Indigenous forests

Louis De Grandpré studies the traditional lands of Canada’s Pessamit people in the face of widespread logging.

Nearly half of the world’s flowering plants face the threat of extinction, study says

A new study estimates that nearly half of the world’s known flowering plants are threatened. Scientists built an AI model using plants they know are threatened or safe, then used it to estimate how many others are threatened as well. The research team hopes to get more plants included on the IUCN Red List, which helps protect threatened species from habitat loss.

Unisexual flowers as a resolution to intralocus sexual conflict in hermaphrodites (OA)

In dioecious populations, males and females may evolve different trait values to increase fitness through their respective sexual functions. Because hermaphrodites express both sexual functions, resolving sexual conflict is potentially more difficult for them. Chen & Pannell show that hermaphrodite plants can partially resolve sexual conflict by expressing different trait values in different male and female modules (e.g. different flowers, inflorescences, branches etc.).

Calcium: A master regulator of stress tolerance in plants ($)

This review emphasizes the role of Calcium, its transportation, sensing mechanisms by cellular proteins (such as CaMs, CBLs, and CDPKs), and the underlying molecular processes in plants under abiotic stress conditions.

Conserved and unique features of pepper FLOWERING LOCUS T-like genes revealed by comparative analysis among solanaceous crops ($)

FLOWERING LOCUS T (FT)-like genes play crucial and antagonistic roles in flowering induction in plants. Kwon et al. analyzed the functional and evolutionary characteristics of pepper FT-like genes. According to their similarity to an FT ortholog of tomato, 10 phosphatidylethanolamine-binding protein family genes were retrieved from the pepper genome. Phylogenetic analysis placed the proteins encoded by six of these genes (CaFT1–CaFT6) into an FT-like clade. Comparative genomic analysis showed that four of pepper FT-like genes (CaFT1, CaFT2, CaFT3, CaFT4) have orthologous counterparts in other three solanaceous crops (tomato, potato, and tobacco). CaFT5, which is unique to pepper, was inferred to have arisen by genomic rearrangement followed by duplication of CaFT2.

Cheap, cost-effective, and quick stress biomarkers for drought stress detection and monitoring in plants (OA)

Munné-Bosch & Villadangos discuss currently available methods that do not require specialized equipment, but reliably detect and monitor drought stress in plants at low cost. This will not only boost research on plant stress physiology in low-income countries but will also help several laboratories with very limited resources around the globe to perform high-quality research.

Latitudinal trends in mating system traits in the highly self-fertilizing Lobelia inflata revealed by community science (OA)

Mating systems in angiosperms range from obligate outcrossing to highly self-fertilizing. The belief that obligate selfing does not exist is contradicted by genetic evidence in several populations of L. inflata, in which selfing is enforced by the anthers enclosing the style. However, whether the mating systems of these populations are typical, or an extreme across the species range is unknown. Such trends are hypothesized to result from selection for reproductive assurance under mate limitation at range margins. Coffey & Simons use ~7500 iNaturalist community science images, in which stylar exsertion can be observed, to test this hypothesis in L. inflata and, for comparison, in four typical congeneric Lobelias that express a staminate, then a pistillate phase (protandry).

Protein Phosphorylation Orchestrates Acclimations of Arabidopsis Plants to Environmental pH (OA)

Environment pH (pHe) is a key parameter dictating a surfeit of conditions critical to plant survival and fitness. To elucidate the mechanisms that recalibrate cytoplasmic and apoplastic pH homeostasis, Jain & Schmidt conducted a comprehensive proteomic / phosphoproteomic inventory of plants subjected to transient exposure to acidic or alkaline pH, an approach that covered the majority of protein-coding genes of the reference plant Arabidopsis thaliana. Their survey revealed a large set so far undocumented pHe-dependent phospho-sites, indicative of extensive post-translational regulation of proteins involved in the acclimation to pHe.
