Ontogeny of the maize shoot apical meristem [PDF]

, 2012
The maize (Zea mays) shoot apical meristem (SAM) arises early in embryogenesis and functions during stem cell maintenance and organogenesis to generate all the aboveground organs of the plant.

Field efficacy of a bioherbicide mimic (DiS‐NH2) in a nanoparticle formulation for weed control in durum wheat

Pest Management Science, Volume 81, Issue 7, Page 3796-3810, July 2025.
A new polymeric nanoparticle formulation containing aminophenoxazinone DiS‐NH2 (2,2′‐disulfanediyldianiline) is proposed as a post‐emergence and contact bioherbicide for weed management in durum wheat. Abstract BACKGROUND Weed‐resistance phenomena have increased dramatically in recent years. Bioherbicides can offer a sustainable alternative to chemical

Long coleoptile genotype and soil texture interactions determine establishment success and early growth parameters of wheat sown at depth

Environmental Research Communications, 2023
Long coleoptile (LC) - wheat genotypes sown deeper (> 10 cm) than current practice (< 5 cm) enables earlier deep sowing into subsurface soil moisture. The LC genotype shows promise to broaden sowing windows and remove reliance on the shifting seasonal ...

Effect of Red Light on Coleoptile Growth [PDF]

Plant Physiology, 1974
The effects of red light in reducing the growth of the oat (Avena sativa L.) coleoptile and the synthesis of auxin in the coleoptile tip are detectable 2 hours after treatment and become more pronounced with time. When the coleoptile tip is supplied with additional tryptophan the synthesis of auxin is doubled both in darkness and when exposed to red ...

HSFA2D–LAZY6–LAZY1 module regulates shoot gravitropism and tiller angle in rice

New Phytologist, Volume 247, Issue 2, Page 625-636, July 2025.
Summary Tiller angle is a critical architectural trait in rice (Oryza sativa), affecting planting density, light interception, and grain yield. While HEAT STRESS TRANSCRIPTION FACTOR 2D (HSFA2D) has been shown to regulate tiller angle via LAZY1 (LA1)‐mediated auxin distribution, the precise mechanisms governing this pathway remain elusive.

Association Analysis and Identification of Candidate Genes for Sorghum Coleoptile Color

Agronomy
Coleoptile is a sheath-like structure unique to monocots and is easily observed in sorghum. Colored coleoptiles have been shown to protect plants against abiotic and biotic stresses.

MDR1 DNA glycosylase regulates the expression of genomically imprinted genes and Helitrons

The Plant Journal, Volume 123, Issue 1, July 2025.
SUMMARY Targeted demethylation by DNA glycosylases (DNGs) results in differential methylation between parental alleles in the endosperm, which drives imprinted expression. Here, we performed RNA sequencing on endosperm derived from DNG mutant mdr1 and wild‐type (WT) endosperm.

Biology, Ecology, Distribution and Management of Large Crabgrass (Digitaria sanguinalis)

Weed Research, Volume 65, Issue 4, July/August 2025.
ABSTRACT Digitaria sanguinalis (L.) Scop. (large crabgrass) is a globally distributed annual C4 grass and one of the most challenging weeds in agriculture, causing significant yield losses in crops such as maize, soyabean, rice, cotton and vegetables. This species thrives under favourable and unfavourable conditions such as disturbed soils, fluctuating

Growth of maize coleoptiles in the presence of natural and synthetic growth regulators. Growth correlations

Acta Societatis Botanicorum Poloniae, 2014
The effect of natural (IAA, FC, ABA) and synthetic (2,4-D) growth substances on the increase of the fresh weight of maize coleoptile segments and change of the pH of the incubation medium, accepted here as criteria of maize coleoptile growth, was studied.

A Genome-Wide Association Study of Coleoptile Length in Different Chinese Wheat Landraces

Frontiers in Plant Science, 2020
From the perspective of wheat yield improvement, the coleoptile is vital for successful crop establishment, and long coleoptile lengths (CLs) are preferred in wheat-growing regions where deep planting is practiced.
