Gibberellin-3 induced dormancy and suppression of flower bud formation in pitaya (Hylocereus polyrhizus).
BMC Plant Biol

Guangdong Provincial Key Laboratory of Postharvest Science of Fruits and Vegetables/Key Laboratory of Biology and Genetic Improvement of Horticultural Crops, Ministry of Agriculture and Rural Affairs, College of Horticulture, South China Agricultural University, Guangzhou, 510642, China.
Background: Flowering is a complex, finely regulated process involving multiple phytohormones and transcription factors. However, flowering regulation in pitaya (Hylocereus polyrhizus) remains largely unexamined. This study addresses this gap by investigating gibberellin-3 (GA3) effects on flower bud (FB) development in pitaya.

The tubers of Curcuma kwangsiensis are regarded as an important medicinal material in China. In C. kwangsiensis cultivation, tuber expansion is key to yield and quality, but the regulatory mechanisms are not well understood.

Drought stress substantially decreases crop yields by causing flowers and fruits to detach prematurely. However, the molecular mechanisms modulating organ abscission under drought stress remain unclear. Here, we show that expression of CALMODULIN2 (CaM2) is specifically and sharply increased in the pedicel abscission zone (AZ) in response to drought and plays a positive role in drought-induced flower drop in tomato (Solanum lycopersicum).

The gonadal anchor cell (AC) is an essential organizer for the development of the egg-laying organ in the C. elegans hermaphrodite. Recent work has investigated the mechanisms that control the quiescent state the AC adopts while fulfilling its functions.

The involvement of Loose Plant Architecture 1 (LPA1) in regulating plant growth and leaf angle has been previously demonstrated. However, the fundamental genetic background remains unidentified. To further understand the tissue expression profile of the NtLPA1 gene, an overexpression vector (pBI121-NtLPA1) was developed and employed to modify tobacco using the leaf disc method genetically.
