Brachypodium SPEECHLESS2 Promoter Drives Expression of a Synthetic EPF to Reduce Stomatal Density in Sugarcane Without Pleiotropic Effects

Plant Biotechnology Journal, EarlyView.
ABSTRACT Stomata are microscopic pores that regulate the exchange of CO2 and water vapour, making them a major target for engineering plants with improved intrinsic water use efficiency (iWUE). Proof‐of‐concept studies have demonstrated the potential to increase iWUE by reducing stomatal density (SD) and stomatal conductance (gsw) by ubiquitously ...

The in silico study of the COBRA gene family in sugarcane related to potential biomass content

Menara Perkebunan, 2022
Sugarcane (Saccharum sp.) is potential as a biofuel and biomaterial source for its high cellulose content. Cellulose is the main constituent of the plant cell wall, as a linear chain arranged in a polysaccharide bundle, called cellulose microfibril.

WRKY Transcription Factors: Integral Regulators of Defence Responses to Biotic Stress in Crops

Plant Biotechnology Journal, EarlyView.
ABSTRACT Crops are continually challenged by biotic stresses, including fungal, bacterial and viral pathogens and insect pests, which cause substantial yield and quality losses worldwide. WRKY transcription factors constitute a plant‐specific and functionally diverse family that is central to immune regulation.

Analysis of biomass traits in sugarcane (Saccharum spp. hybrids) [PDF]

, 2020
Sugarcane is a C4 perennial grass able to efficiently convert light energy into biomass. Bagasse, the fibrous waste product of sugar production, and biomass from high-fiber sugarcane varieties are important feedstocks for replacing fossil carbon in the production of fuels and other chemicals.

A Fusarium sacchari Glycoside Hydrolase 12 Protein FsEG1 Is a Major Virulence Factor During Sugarcane Infection and Confers Resistance to Pokkah Boeng Disease via the HIGS Strategy

Plant Biotechnology Journal, EarlyView.
ABSTRACT Pokkah Boeng disease (PBD), caused by Fusarium sacchari, has severely impacted the yield and quality of sugarcane, resulting in significant economic losses. However, the molecular interaction mechanisms between F. sacchari and sugarcane remain poorly understood.

Alelopatía en Saccharum spp. (caña de azúcar)

AIA Avances en Investigación Agropecuaria, 2011
El presente trabajo es una revisión de la alelopatía en la agricultura. La alelopatía incluye interacciones bioquímicas por exudados de compuestos orgánicos excretados por las plantas y otros organismos (donador) para el ambiente, las cuales provocan inhibición o estímulos en los organismos aceptores.
