Expression dynamics of phytochrome genes for the shade-avoidance response in densely direct-seeding rice [PDF]

open access: yesFrontiers in Plant Science, 2023
Because of labor shortages or resource scarcity, direct seeding is the preferred method for rice (Oryza sativa. L) cultivation, and it necessitates direct seeding at the current density.

Genomic identification of direct seeding and evolutionary lineages by combining heterogeneous genomic resources [PDF]

open access: yesBMC Biology
Background Human-induced habitat changes threaten biodiversity, prompting large-scale restoration initiatives. Revegetation through direct seeding is common in agricultural and infrastructure construction projects, yet the provenance of seed material and

Analysis and Experiment on the Seed Metering Mechanism of Multi-Grain Cluster Air Suction Type Rice (Oryza sativa L.) Hill Direct Seed Metering Device

open access: yesAgriculture, 2022
This paper aims to solve the problem of high reseeding rates and mis-seeding rates in the rice multi-grain hole direct seeding process. A multi grain cluster air suction type rice hill direct seed metering device was developed, and its seeding mechanism ...

Seed-specific promoters direct gene expression in non-seed tissue [PDF]

open access: yesJournal of Experimental Botany, 2004
The organ specificity of four promoters that are known to direct seed-specific gene expression was tested. Whereas the phaseolin (phas)- and legumin B4 (leB4)-promoters were from genes encoding 7S and 11S globulins from Phaseolus vulgaris and Vicia faba, respectively, the usp- and the sbp-promoters were from non-storage protein genes of V. faba.

LODGING IN DIRECT SEEDED PEPPERS [PDF]

open access: yesHortScience, 1993
One of the problems associated with machine harvesting of spice peppers (Capsicum annuum L.) is plant lodging. Factorial combinations of four bedding treatments and two N rates were compared for effects on lodging and fruit yield of Chile at Fort Cobb and Bixby, Okla.. and of paprika at Bixby, Okla.

Switchable lasing in coupled multimode microcavities [PDF]

open access: yes, 2007
We propose the new concept of a switchable multimode microlaser. As a generic, realistic model of a multimode microresonator a system of two coupled defects in a two-dimensional photonic crystal is considered.

Seed covering and dry periods in the rainy season interfere with direct seeding success in the restoration of post-mined grasslands

open access: yesEcología Austral, 2021
Among the limitations for the use of direct seeding in the ecological restoration of severely degraded areas in tropical grasslands, the association between dry periods and an inhospitable substrate stands out.
