Systematic consideration of petiole anatomy of species of Echinodorus Richard (Alismataceae) from north-eastern Brazil

, 2007
Petiole anatomy of the north-eastern Brazilian species Echinodorus glandulosus, E. palaefolius, E. pubescens, E subalatus, E lanceolatus and E paniculatus were examined. All species had petioles with an epidermis composed of tabular cells with thin walls.

Molecular Links Between Heat Stress and DNA Damage Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT Climate change poses a major threat to agricultural productivity and, consequently, to global food security. Among the consequences of climate change, heat stress (HS) has emerged as a critical factor limiting crop performance. This has stimulated extensive research over the past decade to elucidate the molecular and physiological mechanisms ...

Perturbation of Spermine Homoeostasis Uncouples Hypersensitive Cell Death From Systemic Plant Immunity

Plant, Cell &Environment, EarlyView.
ABSTRACT Polyamines are key regulators of plant stress responses, yet their contribution to coordinating local immune responses with systemic immunity remains poorly understood. Here, we investigated how spermine (Spm) homeostasis influences local and systemic defence responses in Arabidopsis thaliana following inoculation with Pseudomonas syringae pv.

BSA-seq and transcriptome analyses reveal candidate gene associated with petiole color in papaya (Carica papaya L.)

Ornamental Plant Research
Papaya (Carica papaya L.) is an important tropical species popular for highly nutritious fruit as well as medicinal value. In addition, non-commercial cultivation of papaya trees has resulted in dual-purpose cultivars grown for both fruit and ornamental ...

Genetic diversity in soybean [Glycine max (L.) Merr.] genotypes based on agro‐morphological traits using univariate and multivariate statistical techniques

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Soybean [Glycine max (L.) Merr.] is a versatile leguminous crop that plays a vital role in biodiesel production, livestock feed, and enhancing global food security. Soybean production and productivity in Ethiopia are low compared to the national potential, mainly due to the lack of high‐yielding genotypes.

Reduction of mineral fertilizer use through municipal solid waste compost application in potted spinach (Spinacia oleracea L.)

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract The overuse of mineral fertilizers can harm the environment and reduce crops quality. The combined use of N fertilizers with organic amendments may provide a more sustainable fertilization strategy. This study aimed to evaluate the effects of source‐separated organic fraction of municipal solid waste (OFMSW) compost application on crop yield ...

Kin discrimination in plants: overview and implications for population and community ecology

Biological Reviews, Volume 101, Issue 6, Page 2656-2669, December 2026.
ABSTRACT Following the discovery of identity discrimination, particularly self and kin discrimination amongst plant competitors, research on interplant interactions has advanced significantly within plant physiology and evolutionary ecology. This review synthesizes current knowledge on how both self and kin discrimination influence plant growth ...

Conventional and chlorophyll meter–based nitrogen fertilization management for sweetpotato in the tropics

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Sweetpotato [Ipomoea batatas (L.) Lam.] exhibits low nitrogen (N) uptake during early growth stages, suggesting that N fertilization at planting may be unnecessary. A portable chlorophyll meter can be a useful tool for more precise determination of the timing and rate of topdressed N applications, thereby aligning fertilization with crop ...

SP290-M Maple Petiole Borer [PDF]

, 2010
The maple petiole borer, Caulocampus acericaulis (MacGillivray), was first introduced into the United States from Europe. This sawfly is wasp-like in appearance and is rarely seen because of its small size.
