“…Owing to the small size of the xylopodium and the restricted location of the buds on this organ, the number of buds is fewer ( c . 150 recorded in Eupatorium ligulaefolium ; Fidelis et al ., ), and their xylem is not as contorted as in lignotubers (Appezzato‐da‐Glória et al ., ; Lopes‐Mattos et al ., ; da Silva et al ., ). Some species store fructans or starch in the xylopodium (Table S2); however, in most cases the xylopodium lacks reserves and these are instead associated with the tuberous roots where carbohydrates are stored (Table S2; Fig.…”

Despite long-time awareness of the importance of the location of buds in plant biology, research on belowground bud banks has been scant. Terms such as lignotuber, xylopodium and sobole, all referring to belowground bud-bearing structures, are used inconsistently in the literature. Because soil efficiently insulates meristems from the heat of fire, concealing buds below ground provides fitness benefits in fire-prone ecosystems. Thus, in these ecosystems, there is a remarkable diversity of bud-bearing structures. There are at least six locations where belowground buds are stored: roots, root crown, rhizomes, woody burls, fleshy swellings and belowground caudexes. These support many morphologically distinct organs. Given their history and function, these organs may be divided into three groups: those that originated in the early history of plants and that currently are widespread (bud-bearing roots and root crowns); those that also originated early and have spread mainly among ferns and monocots (nonwoody rhizomes and a wide range of fleshy underground swellings); and those that originated later in history and are strictly tied to fire-prone ecosystems (woody rhizomes, lignotubers and xylopodia). Recognizing the diversity of belowground bud banks is the starting point for understanding the many evolutionary pathways available for responding to severe recurrent disturbances.

“…The buds are axillary or adventitious originating from the cambium of the xylopodium; they are usually located on the upper part of the xylopodium, i.e. close to the soil surface (Lopes-Mattos et al, 2013;da Silva et al, 2014). They may be supported by a taproot tuber (Fig.…”

“…Xylopodia and other underground organs are common in shrubs in campo rupestre and in other OCBILs (Veldman et al 2015). They may play a role in water storage (Lopes-Mattos et al 2013), but also represent significant reserves of nutrients and carbohydrates, which can be utilised during resprouting after fire, extreme droughts (Neves and Conceição 2010) or herbivory. Aerenchyma occurs in roots of plants from peat bogs in campo rupestre (Coan et al 2002).…”

“…Individuals from several botanical families worldwide have the ability to regenerate their photosynthetic shoots in fire-prone ecosystems (Burrows 2008. However, despite the effort to understand morphoanatomical traits of plants from Cerrado, only a small number of species were analyzed in previous studies conducted on Apocynaceae (Appezzato-da-Glória & Estelita 2000b, Lopes-Mattos et al 2013, Asteraceae (Appezzato-da-Glória & Cury 2011, Bombo et al 2014), Fabaceae (Milanez & Moraes-Dallaqua 2003), Rutaceae (Rodrigues et al 2004, Hayashi & Appezzato-da-Glória 2009 and Smilacaceae species (Martins et al 2010a). There is no information about resprouting mechanisms in Myrtaceae from Cerrado even if it is one of the most important botanical family in this domain (Fiaschi & Pirani 2009) with 21 genera and approximately 344 described species (Mendonça et al 2008).…”

Resprouting is a functional trait in species which occur in fi re-prone ecosystems. These plants can resprout from aerial buds and by recruiting belowground bud bank using carbohydrates allocated in roots as resource. In this study, we present morpho-anatomical features and chemical composition related to the resprouting potential of two species of Eugenia L. in an area of the Cerrado (Brazilian savanna) under regeneration, after the clear-cutting of Pinus sp. with the later burning of pine needles layer. We used standard histological techniques for belowground organs analysis and aerial buds protection degree. Belowground buds in layer from soil surface down to 10 depth were counted and the chemical analyses were performed on roots. In all aerial buds, there were relevant protection traits. The belowground organ is a sobole and the number of buds in its upper portion varied from 24 to 517 between individuals of both species. Phenolic compounds, fl avonoids, starch and other carbohydrates were detected in roots. The protection of aerial buds, the large number of belowground buds and the storing and protective compounds may have favored the resprouting of the species in the area.
