Response of cotton cultivars with varying maturity traits to cotton fleahopper (Hemiptera: Miridae) feeding

Abstract Cotton fleahopper, Pseudatomoscelis seriatus Reuter (Hemiptera: Miridae), is an early season pest of upland cotton, Gossypium hirsutum L. Feeding damage from this causes square abscission. The response commercial cotton cultivars with varying maturity traits to fleahopper feeding was assessed. hypothesis that affects and late-maturing differently in delays yield. Field experiments natural artificial infestations were conducted Corpus Christi, TX. For the infestation experiment, 4 (DP 2020 B3XF, DP 2012 PHY 332 W3FE, 545 W3FE) assigned main plots, subplots either sprayed or not thiamethoxam insecticide control season. experiment used 2 B3XF as infested using single caging. In no-spray increased abscission, leading yield loss delayed boll maturity, especially classified late-maturing. Early maturing consistently showed faster opening regardless fleahopper. Artificial further confirmed reduced numbers, lower lint weights when are more resilient may be particularly useful areas high pressure, scheduling harvest desirable.

RNA Interference-Mediated Suppression of GhSP (SELF-PRUNING) Modulates the Plant Architecture of Transgenic Cotton in a Dose-Dependent Manner

Biology, Год журнала: 2025, Номер 14(6), С. 601 - 601

Опубликована: Май 25, 2025

Cotton exhibits indeterminate growth potential at its apical meristem. In field cultivation, it is often necessary to restrict plant height by the foliar application of regulators or artificial topping. The genetic engineering cotton architecture offers an efficient, environmentally friendly, and low-cost alternative current management. Our study aimed improve transgenic suppression GhSP, a key flowering repressor, via RNA interference method. Sixteen independent lines were generated classified as mildly, moderately, severely suppressed, according GhSP expression levels. Field evaluation revealed dose-dependent effects silencing on height. mildly suppressed line GhSPi-#5 exhibited semi-dwarf phenotype approximately 70~100 cm in Negative phenotypes, including excessive dwarf inferior fiber quality yield traits, observed GhSP-suppressed lines. Notably, mild did not negatively affect leaf flower organ growth, pollen fertility, major agronomic compared with wild type. These observations demonstrate feasibility manipulating silencing.

Functional dissection of phytochrome A in plants

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Янв. 26, 2024

Plants lack behavioral responses to avoid dramatic environmental changes associated with the annual seasons. For survival, they have evolved complex sensory systems sense fluctuations in light and optimize their architecture response these cues. Phytochrome A (phyA) was initially identified as a photoreceptor that senses far-red signals. It then playing central role promoting hypocotyl growth, fiber development, flowering time variety of plants including Arabidopsis, rice, soybean cotton. Under dark conditions, phyA is present cytoplasm physiologically inactive (Pr) form. Far-red signals induce transformation Pr into active (Pfr) form, after which Pfr-phyA recognized by FAR-RED ELONGATED HYPOCOTYL 1 (FHY1) FHY1-LIKE (FHL) translocated nucleus, initiating series signaling cascades. The current review comprehensively summarizes recent advances understanding function plants, phyA-mediated shade avoidance time. Remaining issues possible directions for future research on are also discussed.

A cotton mitochondrial alternative electron transporter, GhD2HGDH, induces early flowering by modulating GA and photoperiodic pathways

Опубликована: Май 1, 2024

Abstract D‐2‐hydroxyglutarate dehydrogenase (D2HGDH) is a mitochondrial enzyme containing flavin adenine dinucleotide FAD, existing as dimer, and it facilitates the specific oxidation of D‐2HG to 2‐oxoglutarate (2‐OG), which key intermediate in tricarboxylic acid (TCA) cycle. A Genome‐wide expression analysis (GWEA) has indicated an association between GhD2HGDH flowering time. To further explore role , we performed comprehensive investigation encompassing phenotyping, physiology, metabolomics, transcriptomics Arabidopsis thaliana plants overexpressing . Transcriptomic qRT‐PCR data exhibited heightened upland cotton flowers. Additionally, early‐maturing higher across all tissues than delayed‐maturing cotton. Subcellular localization confirmed its presence mitochondria. Overexpression resulted early flowering. Using virus‐induced gene silencing (VIGS), investigated impact on both early‐ plants.

Sphingolipid inhibitor response gene GhMYB86 controls fiber elongation by regulating microtubule arrangement

Journal of Integrative Plant Biology, Год журнала: 2024, Номер 66(9), С. 1898 - 1914

Опубликована: Июль 12, 2024

ABSTRACT Although the cell membrane and cytoskeleton play essential roles in cellular morphogenesis, interaction between is poorly understood. Cotton fibers are extremely elongated single cells, which makes them an ideal model for studying development. Here, we used sphingolipid biosynthesis inhibitor, fumonisin B1 (FB1), found that it effectively suppressed myeloblastosis (MYB) transcription factor GhMYB86, thereby negatively affecting fiber elongation. A direct target of GhMYB86 GhTUB7 , encodes tubulin protein, major component microtubule cytoskeleton. Interestingly, both overexpression caused ectopic arrangement at tips, then leading to shortened fibers. Moreover, GhMBE2 interacted with FB1 reactive oxygen species induced its transport into nucleus, enhancing promotion by GhMYB86. Overall, established a GhMBE2‐GhMYB86‐ regulation module elongation revealed sphingolipids affect altering arrangement.
