In higher plants, the morphology of the plant mainly depends on the development and orientation of the shoots therefore, plant shoots, which are usually negatively geotropic, play a crucial role in morphological architecture formation in many plants, such as landscape plants, fruit trees and other plants of economic interest. This study provides a valuable foundation for further understanding the regulation of plant architecture formation and for the cultivation and application of horticultural plants in the future. Our results suggest that zigzag-shaped shoot formation might be associated with the gravitropism response and polar auxin transport in tea plants. Metabolomic analysis showed that 13 metabolites overlapped and were significantly changed in the shoots of QQ and LYQQ compared to MZ. Additionally, the DEGs associated with cell expansion, vesicular trafficking, phytohormones, and transcription factors were identified and analysed. Moreover, a total of 2175 differentially expressed genes (DEGs) were identified from the zigzag-shaped shoots of the tea plants QQ and LYQQ compared to the shoots of MZ using transcriptome sequencing, and the DEGs involved in the “Plant-pathogen interaction”, “Phenylpropanoid biosynthesis”, “Flavonoid biosynthesis” and “Linoleic acid metabolism” pathways were significantly enriched. Tissue section observation showed that the cell arrangement and shape of zigzag-shaped stems were aberrant compared with those of normal shoots. In this study, tea plants with zigzag-shaped shoots, namely, Qiqu (QQ) and Lianyuanqiqu (LYQQ), were investigated and compared with the erect-shoot tea plant Meizhan (MZ) in an attempt to reveal the regulation of zigzag-shaped shoot formation. Zigzag-shaped shoots have been selected and thoroughly studied in Arabidopsis however, the regulatory mechanism underlying zigzag-shaped shoot development in other plants, especially woody plants, is largely unknown. Poisonous to Humans: Poison Severity: Low Poison Symptoms: Nausea, salivation, vomiting, abdominal pain, diarrhea, lethargy, elevated temperature following ingestion skin irritation upon contact with seeds, rootstock, or cell sap.Shoot orientation is important for plant architecture formation, and zigzag-shaped shoots are a special trait found in many plants.Landscape: Landscape Location: Riparian Walkways Landscape Theme: Cutting Garden Water Garden Design Feature: Border Mass Planting Resistance To Challenges: Wet Soil Problems: Poisonous to Humans Problem for Cats Problem for Dogs Problem for Horses.Stem: Stem Color: Green Stem Is Aromatic: No Stem Form: Zig Zags.Cultural Conditions: Light: Full sun (6 or more hours of direct sunlight a day) Partial Shade (Direct sunlight only part of the day, 2-6 hours) Soil Texture: High Organic Matter Loam (Silt) Soil pH: Acid ( 6 inches Leaf Width: 1-3 inches.Whole Plant Traits: Plant Type: Poisonous Wildflower Habit/Form: Erect Maintenance: Medium.Attributes: Genus: Iris Species: brevicaulis Family: Iridaceae Uses (Ethnobotany): Forest, woodlands, or natural area, Life Cycle: Bulb Perennial Recommended Propagation Strategy: Division Root Cutting Country Or Region Of Origin: Ontario to North Central & Eastern U.S.A.

It spreads by the division of its bulb or rhizome. Bloom time is June, though they are not produced each year. The showy flowers are formed as 6-parted, with 3 outer, spreading or pendent "falls" and 3 inner, erect "standards", and are bluish-purple to white with a yellow and white crest on the reflexed falls. The one to several blooms emerge from the top of a naked stem which zig-zags for up to 5 inches, giving the iris one of its common names, Zigzag Iris. Its strap-like leaves rise from rhizomes in a flat plane overlapping at the base which may hide the flowers. This low growing iris is in a family of perennial herbs. Phonetic Spelling EYE-riss brev-ee-KAW-liss This plant has low severity poison characteristics.
