Flowering time influences both #grain yield and #adaptability in #rice. In a new study, Wei et al. report that the florigen-like protein OsFTL1 promotes #flowering...without essential florigens Hd3a and RFT1. https://doi.org/10.1111/jipb.13856

#PlantSci #JIPB #CropSci #botany

Diagram representing the mechanism within the apical meristem, by which OsFTL1 interacts with GF14c and OsFD1 to form the Florigen activation complex (FAC), promoting flowering. Overexpression of OsFTL1 leads to early flowering, even without essential florigens Hd3a and RFT1.

🚨BREAKTHROUGH ALERT!🚨
Using a #CRISPR/Cas9-facilitated targeted knockout of the betaine aldehyde dehydrogenase #genes AhBADH1 and AhBADH2, Xue et al. have created the first fragrant🥜#peanut lines!

@wileyplantsci
#PlantSci #CropSci #agriculture #FoodSci #openaccess #botany

A combination of diagrams, graphs and morphological images of WT and Fragrant peanut lines illustrates that targeted knockout of the betaine aldehyde dehydrogenase genes AhBADH1 and AhBADH2 using CRISPR/Cas9 produces mutant lines with significantly elevated 2-acetyl-1-pyrroline levels and a strong aroma, marking the first creation of fragrant peanut lines.

Dense #planting reduces internal #light intensity and red:far-red ratio in the canopy, triggering shade avoidance responses that limit #yield enhancements. DBB2, a ZmBBX gene, is a crucial regulator of plant height and the shade avoidance response.

Diagrams comparing WT and dbb2 mutant plants in high R:FR vs. low R:FR conditions. Increasing maize planting density enhances yields but reduces light intensity and red:far-red ratio, triggering shade avoidance responses. Double B-box zinc finger protein 2 functions as a key regulator of plant height and shade avoidance responses in maize, with potential as a genetic target for improving maize varieties in high-density conditions.

In a new JIPB commentary, Xiaoyu Guo and Kang Chong discuss new work from Zeng et al. (2025, Cell) that explores the role of COOL1 in #maize cold #adaptation: its significance for high-latitude adaptation and potential for breeding cold-tolerant maize. https://doi.org/10.1111/jipb.13865

Annotated map of the Americas, illustrating the proportional distribution of haplotypes (HapA and HapB) in 1,008 maize landraces from different latitudinal regions of the Americas. Inset shows that, under cold stress, HY5 binds more effectively to the COOL1HapA promoter due to natural variations in the A-box (TACGTA), reducing COOL1 expression and enhancing cold tolerance in COOL1HapA lines. The differential HY5 binding affinities lead to varying COOL1 transcription and translation levels, affecting the activation of cold-responsive genes.

This stylized cross-section of an orange features an enlarged, annotated flow diagram to illustrate that the tonoplast-localized sugar transporter CsTST2 has sucrose and hexose transporter activity and contributes to sugar accumulation in the vacuole. Furthermore, the calcium sensor complex CsCBL1/CIPK23 interacts with and phosphorylates CsTST2 to regulate its transporter activity, which in turn controls the sugar content in citrus fruit.
