Morphological Characters Related to Varietal Differences in Tolerance to Deep Sowing in Wheat

open access: yesPlant Production Science, 2002
In the dry regions, crops are often sown deeper than in the wet regions, because of the relatively high stability of water content of the deep soil layers.

Association Mapping Reveals Novel Genetic Loci Contributing to Flooding Tolerance during Germination in Indica Rice

open access: yesFrontiers in Plant Science, 2017
Rice (Oryza sativa L.) is the only cereal crop that possesses the ability to germinate under flooded or other oxygen-deficient conditions. Rapid elongation of the coleoptile is a perfect response to flooding during germination, with coleoptile length ...

Metabolite Screening From Pinus pinea Needles Reveals (+)‐Isocupressic Acid as a Key Phytotoxin for Weed Management

open access: yesPhytochemical Analysis, EarlyView.
This study explores the phytotoxicity of Pinus pinea needle extracts and metabolites to evaluate their potential for controlling dicotyledonous weeds. A strategy based on GC–MS, NMR, and optical methods revealed an array of aromatic compounds which are of crucial interest for phytochemical research. Hence, a bio‐guided purification led to the isolation

Mesocotyl Elongation is Essential for Seedling Emergence Under Deep-Seeding Condition in Rice

open access: yesRice, 2017
Background Direct-seeding cultivation by deep-seeding of seeds (drill seeding) is becoming popular due to the scarcity of land and labor. However, poor emergence and inadequate seedling establishment can lead to yield loss in direct-seeding cultivation ...

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

open access: yesPest 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

Rice Cultivars with Higher Sucrose Synthase Activity Develop Longer Coleoptiles under Submerged Conditions

open access: yesPlant Production Science, 2008
Sucrose synthase, which catalyzes uridine diphosphate (UDP)-dependent cleavage of sucrose into fructose and UDP-glucose, is induced by oxygen deficiency in rice seedlings and is considered to play an important role in energy production under hypoxic ...

Rht8 gene as an alternate dwarfing gene in elite Indian spring wheat cultivars.

open access: yesPLoS ONE, 2018
Optimizing wheat height to maximize yield has been an important aspect which is evident from a successful example of green revolution. Dwarfing genes (Rht) are known for yield gains due to lodging resistance and partitioning of assimilates into ear.

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

open access: yesNew Phytologist, EarlyView.
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.
