Walter–Lieth climate diagrams (A and B) and maximum VPD (C). The figure shows monthly averages from 2016 to 2022, with data from meteorological stations near each site. Data for “CEES” (A) were obtained from La Bachata meteorological station (REMAS 2024, −111.13190 W 28.96421 N), while data for “Rancho La Pintada” (B) were collected from the Ortiz-La Campana meteorological station (REMAS 2024, − 110.65688 W, 28.30228 N). A–B panels have a dry period (dotted area) when the precipitation plot is positioned below the temperature graph. Otherwise, the period is considered wet (filled in continuous lines).

Population structure of 266 samples of sundial lupine described at K = 5. a) The map depicts the probability of genetic cluster assignment across the 25 sampled populations. Probability is described by up to five colours within-population pie charts. b) The bar plot shows individuals grouped by populations based on microsatellite data. Each vertical bar represents an individual and the corresponding unique colour represents the assigned genetic cluster. Membership probability to a genetic cluster is shown by the length of the bar for each individual.

🧬 New article in @aobp.bsky.social reports a streamlined genetic transformation method for pearl and finger millet, achieving up to 18% efficiency and enabling CRISPR-based gene editing in seeds.

Full #openaccess
👉 doi.org/qb94

#PlantScience
Steps followed for the seed-piercing transformation protocol in pearl millet and finger millet. The pearl millet seeds of ICMB95444 genotype were (A) soaked in water for 18–20 h, (B) subsequently, the soaked seeds were placed in a 90-mm Petri dish containing the Agrobacterium suspension. Similarly, the seeds of finger millet belonging to the KNE796 genotype were (C) also soaked for 16–20 h and (D) placed in Agrobacterium suspension. The embryonic portion of (E) pearl millet and the (F) finger millet seeds were pierced with a needle that had been dipped in Agrobacterium suspension carrying the binary vector, and (G, H) subjected to vacuum infiltration at 15 mmHg for 15 min. The infected (I) pearl millet and (J) finger millet seeds were inoculated on co-cultivation media for 3 days. The flowchart on the right depicts the protocol component of seed-piercing transformation. The protocol commences with the soaking of sterilized seeds in autoclaved water, followed by piercing with a sterile needle dipped in the Agrobacterium suspension. The infected seeds were then placed on co-cultivation media for 3 days in the dark.

#PlantScience
Psittacanthus auriculatus (Loranthaceae) is an endemic species with a narrow distribution to the arid valleys of the states of Oaxaca and Puebla, Mexico. The authors report significant chloroplast genome size variation among five species of Psittacanthus, high conservation of gene order (synteny) or collinearity across species, and different gene loss and pseudogenization patterns from other hemiparasites in Loranthaceae (see Morales-Saldaña et al., pp. 000–000).

Panels e–g show posterior frailties (measured by log odds ratio) for the three models considered, red colouring represents higher frailty. Higher frailties indicates a greater probability of embolism. Censored vein segments are visualized by thinner veins, while vein segments that embolized during observation are represented by thicker veins. (e) Spatial-Independent model. (f) Spatial-Dependent model. (g) Spatial-Dependent-Vein-Thickness model.
