Most cacti in subfamily Cactoideae have tiny foliage leaves (most less than 1.5 mm long) hidden by enlarged axillary buds (the spine clusters). Leaf development similar to that of Arabidopsis and other model plants occurs in six species that have a rudimentary lamina, mesophyll, vascular tissue, stomata, and dorsiventral asymmetry. In the other 141 species, mature foliage leaves are progressively simpler, as if development stops at different points during otherwise ordinary morphogenesis. In 21… 

Secondary Growth of the Leaf and Bud Traces in Hylocereus undatus (Cactaceae) during the Formation of Branches or Flowers

TLDR
The objective of this research was to analyze the secondary growth of these two structures as they develop from their initial state as leaf/bud traces that connect the axillary bud with the stele of the parental shoot.

Different Ways to Build Succulent Leaves in Portulacineae (Caryophyllales)

TLDR
Leaf histogenesis is examined in species of four families with succulent leaves—Basellaceae, Didiereaceae, Portulacaceae, and Talinaceae—through optical microscopy to better understand the mechanisms underlying the development of different leaf morphologies within this group.

Many Cacti Have Clusters of Terminal Tracheids on Their Cortical Bundles

Abstract: Most cacti in subfamily Cactoideae have a thick cortex vascularized by a network of cortical bundles. It was noticed that some cortical bundles had a leaf-like feature: clusters of terminal

Morphogenesis in the Parasitic Plant Viscum minimum (Viscaceae) Is Highly Altered, Having Apical Meristems but Lacking Roots, Stems, and Leaves

TLDR
The body of V. minimum is examined inside its host and the ways its morphogenesis differs from that of ordinary plants such as Arabidopsis are determined to greatly expand the understanding of morphogenesis in all plants.

Evolution of leaf and habit characters in Opuntioideae (Cactaceae): reconstruction of ancestral form

TLDR
Diversity in Opuntioid morphological features (below ground storage organs, stem shape, and leaf persistence) in the phylogenetic context shows a trend towards increased size and surface area.

In vitro Plant Regeneration of Thanks Giving Cactus [Schlumbergera truncata (Haw.) Moran] from Sliced Segment Section for Shoot Proliferation

TLDR
Cactus is a member of the family Cactaceae, comprising of 127 genera with some 1750 known species of the order Caryophyllales which are native to America and South Africa and subtropical North and South American house the highest number of species.

The Potential Roles of Unique Leaf Structure for the Adaptation of Rheum tanguticum Maxim. ex Balf. in Qinghai–Tibetan Plateau

Leaves are essential plant organs with numerous variations in shape and size. The leaf size is generally smaller in plants that thrive in areas of higher elevation and lower annual mean temperature.

Systematics of Harrisia (Cactaceae)

TLDR
DNA sequence analyses in this study do not clearly resolve generic relationships with Harrisia, but the flower morphology suggests a relationship between Harrisia and some species of Echinopsis s.

Molecular phylogeny and character evolution in terete-stemmed Andean opuntias (Cactaceae-Opuntioideae).

Phytochemical Screening for Leaves,Cortex and Pith of the Cactus Euphorbia trigona L.

TLDR
E. trigona could be a potential source of active principles which may help to discover new chemical classes of drugs that could serve as selective agents for the maintenance of health, and hence, this study recommends to run a further studies to identify the active constituents, as well as to verify the biological activities of this plants.

Giant shoot apical meristems in cacti have ordinary leaf primordia but altered phyllotaxy and shoot diameter.

TLDR
This study examined how SAM size affects leaf primordium (LP) size, phyllotaxy and shoot diameter in cacti, and suggested genes such as SHOOT-MERISTEMLESS, WUSCHEL and CLAVATA must control much larger volumes of SAM tissue in cacts than they do in A. thaliana.

Structure-function relationships in highly modified shoots of cactaceae.

TLDR
This review explains cactus shoot structure, discusses relationships between structure, ecology, development and evolution, and indicates areas where research on cacti is necessary to test general theories of morphogenesis.

Anatomical Adaptations to Xeric Conditions in Maihuenia (Cactaceae), a Relictual, Leaf-Bearing Cactus

TLDR
Although closely related, maihuenias have fewer relictual features than do pereskias, and plants of Pereskia probably are more similar to the ancestral cacti.

A review of the information that is currently available about various mechanisms of leaf development in Arabidopsis finds that vascular patterning is also an important factor in the determination of leaf shape.

Basal cactus phylogeny: implications of Pereskia (Cactaceae) paraphyly for the transition to the cactus life form.

TLDR
A new hypothesis of phylogenetic relationships at the base of the Cactaceae is presented, inferred from DNA sequence data from five gene regions representing all three plant genomes, which support a basal split between a clade of eight Pereskia species, centered around the Caribbean basin, and all other cacti.

Relictual vegetative anatomical characters in Cactaceae: the genusPereskia

TLDR
Pereskia features may be relictual in the Cactaceae and were studied to establish a basis for determining the ways that morphogenic mechanisms and anatomical characters diversified as the family evolved.

Pereskia and the Origin of the Cactus Life‐Form

TLDR
Ancestral trait reconstruction for the physiological and environmental data provides a preliminary assessment of the ecology and water relations of the earliest cacti and suggests that several key elements of the cactus ecological niche were established before the evolution ofThe cactus life‐form.

HORMONAL CONTROL OF ORGANOGENESIS IN OPUNTIA POLYACANTHA (CACTACEAE)

TLDR
Explants on medium lacking hormones show no structural change, but by the tenth day are insensitive to BAP or NAA, and four types of lateral appendage can be produced: leaves, mildly altered leaves, leaf-spine transition forms, and spines.
