Construction and application of star polycation nanocarrier-based microRNA delivery system in Arabidopsis and maize

open access: yesJournal of Nanobiotechnology, 2022
Background MicroRNA (miRNA) plays vital roles in the regulation of both plant architecture and stress resistance through cleavage or translation inhibition of the target messenger RNAs (mRNAs).

The Development of Polyamines throughout Brassica rapa over its Lifecycle [PDF]

open access: yes, 2014
Polyamines are naturally produced chemicals in plants involved in growth, development and stress response. The primary objective of my study is to create a profile of changes in the entire life of the plant, in every organ at all stages of development ...

Modelling the effects of osmotic stress on tomato fruit development [PDF]

open access: yes, 2017
Whereas most high-tech tomato greenhouses focus primarily on high production yields, consumers prefer a higher quality product. Dry matter content is one of the key factors determining fruit quality, and is known to be substantially influenced by ...

Evaluation of Harvest Aid Chemicals for the Cotton-Winter Wheat Double Cropping System

open access: yesJournal of Integrative Agriculture, 2013
Timing of harvest is critical for mechanical picking in cotton production, especially in those regions with double cropping system. Appropriate and safe harvest aids will improve timing and facilitate harvest of cotton in the double cropping system ...

Modelling root distribution and nitrogen uptake [PDF]

open access: yes, 2004
Plant soil and atmosphere models are commonly used to predict crop yield and environmental consequence. Such models often include complex modelling modules for water movement, soil organic matter turnover and, above ground plant growth.

Biomechanics of plant growth [PDF]

open access: yesAmerican Journal of Botany, 2006
Growth of turgid cells, defined as an irreversible increase in cell volume and surface area, can be regarded as a physical process governed by the mechanical properties of the cell wall and the osmotic properties of the protoplast. Irreversible cell expansion is produced by creating a driving force for water uptake by decreasing the turgor through ...

The sensitivity of plant tissue culture and plant cell of citrullus lanatus cv. round dragon against basta® [PDF]

open access: yes, 2010
Current study provides an efficient screening system for transformed plant of Citrullus lanatus cv. Round Dragon harboring bar gene. The untransformed 5-day-old cotyledon explants were cultured on the shoot-inducing media supplemented with Basta® (0.2, 0.

Accelerated growth increases the somatic epimutation rate in trees

open access: yesNature Communications
Trees are integral to ecosystems and hold considerable economic importance. Their exceptional longevity and modular structure also make them valuable models for studying the long-term accumulation of somatic mutations and epimutations in plants ...
