Resurrection plants

A cactus avoids drying out. A resurrection plant lets it happen — dries to a crisp, waits months, and revives within hours of rain.

Resurrection plants dry to a brown crisp, stay that way for months, and revive within hours of rain. They appear to do it by switching on in their leaves the desiccation-tolerance programme that nearly every flowering plant already runs in its seeds.

The distinction that makes this subject work is between avoiding drying and surviving it. A cactus is not a resurrection plant; it is a water store with a waxy skin, arranged so that its tissues never dry out. A resurrection plant does the opposite: it lets its leaves lose almost all their water, down to air-dryness, and survives in that state. Where they grow explains why. Typically it is shallow soil over rock — nowhere to send a deep root, no water store to build, and no possibility of avoiding a dry season. When avoidance is not available, tolerance is what is left. The evolutionary story is a good one and it echoes the antifreeze case from the cold wave. Vegetative desiccation tolerance was probably present in the earliest land plants and is retained in mosses, but among flowering plants it appears to have been re-derived independently several times — and the most plausible route is not building it from nothing but switching on somewhere new a programme the plant already had. Nearly every flowering plant makes desiccation-tolerant tissue routinely: its seeds. The sugars, the protective proteins, the antioxidant systems are all already there, expressed during seed maturation. A resurrection plant looks like a plant that turned that programme on in its leaves. One problem is unique to doing it in a leaf, and it is the part most accounts skip. A seed is not photosynthesising. A drying leaf in sunlight still has chlorophyll catching light it can no longer do anything with, and that captured energy has to go somewhere — which, in a cell with no water to work with, means damage. So much of what a resurrection plant does while drying is not protecting itself against dryness at all. It is dismantling or shielding its own light-harvesting machinery before that machinery destroys it.

What this page covers

Several hundred flowering plant species across many unrelated families, concentrated in seasonally arid rocky habitats, plus the mosses and lichens where the capacity is far commoner and much older.

Often confused with: Drought-resistant plants, which avoid water loss rather than surviving it; Succulents, which store water and are doing the opposite thing; Annuals that die and leave seeds, where it is the seed that survives and not the plant

Quick facts

What they do
Dry to air-dryness and recover, rather than avoiding water loss
Where the machinery came from
Most likely the seed programme, switched on in leaves
The problem a seed does not have
A drying leaf is still catching sunlight it cannot use
Where they grow
Shallow soil over rock — where avoiding the dry season is not an option

Tolerating, not avoiding

The opposite strategy from a succulent, and it goes with a particular kind of place.

Nearly every flowering plant already makes desiccation-tolerant tissue: its seeds. Resurrection plants appear to have switched that programme on in their leaves, rather than inventing tolerance from scratch.

Well supported

Good evidence backs this, though some details remain open.

Vegetative desiccation tolerance in angiosperms appears to be re-derived multiple times independently, most plausibly by redeployment in vegetative tissue of the protective programme — sugars, late embryogenesis abundant proteins, antioxidant systems — already expressed during orthodox seed maturation.

Who this applies to
Flowering plants with desiccation-tolerant vegetative tissue, in several independently derived lineages.
Studied in
Plantae
Why we rate it this way, and what the caveats are
Well supportedModerate confidence

The shared molecular repertoire is directly documented. That redeployment is the evolutionary route is a reconstruction that depends on the phylogeny and on how tolerance is scored, and is better supported in some lineages than others.

How far it can be extended

The shared protective repertoire between seeds and resurrection plants has been characterised in several unrelated lineages that acquired vegetative tolerance separately.

Caveats

  • The seed programme is necessary but not sufficient: a green leaf must also shut down photosynthesis safely, which a seed never has to do.
  • Ancestral state reconstruction is sensitive to the phylogeny used, and both have been revised since the original analysis.

Still unanswered

  • What regulatory change switches the seed programme on in vegetative tissue, and whether it is the same change in each lineage.

The evidence (3 studies)
Three ways a plant deals with a dry season
StrategyWhat it doesWhere it works
Avoid — storeHolds water in tissue behind a waxy skinWhere enough water arrives to store
Avoid — escapeDies back, leaves seeds or an underground organWhere the plant can afford to start again
TolerateDries out entirely and survives itShallow soil over rock, where the first two are unavailable

The third row is a small habitat and a distinctive one. On a rock outcrop with a centimetre of soil there is nothing to store water in and nowhere for a root to go, and the plant cannot retreat underground because there is no underground. Everything that lives there permanently either tolerates drying or is a moss or lichen that has been doing so all along.

A programme the plant already had

Nearly every flowering plant makes desiccation-tolerant tissue. It is called a seed.

An orthodox seed dries to a few per cent water content, survives for years, and germinates. That is desiccation tolerance, achieved with sugars that vitrify the cell contents, protective proteins that hold structures in place as the water leaves, and antioxidant systems that mop up the damage of the transition. It is one of the most ordinary things in botany. The comparative evidence suggests resurrection plants are running the same repertoire, in leaves — which reframes the question from "how did a plant evolve something so extraordinary" to "what regulatory change lets an existing programme run somewhere new". That is the same shape of answer as the fish antifreeze that came from a digestive enzyme, and it is the commoner shape in this whole subject.

A drying leaf in sunlight is still catching light it can no longer use, and that is actively dangerous. Much of what a resurrection plant does while drying is dismantling or shielding its own photosynthetic machinery.

Well supported

Good evidence backs this, though some details remain open.

Desiccating photosynthetic tissue accumulates damaging reactive oxygen species when light capture continues without the capacity to use the absorbed energy. Resurrection plants manage this either by dismantling chlorophyll and thylakoid membranes during drying, or by retaining them under protective screening pigments and elevated antioxidant capacity.

Who this applies to
Resurrection plants with green vegetative tissue; the two strategies divide the group.
Studied in
Plantae
Why we rate it this way, and what the caveats are
Well supportedModerate confidence

The photo-oxidative problem is well established in plant physiology generally, and both management strategies are documented in resurrection species. The relative importance of the mechanisms differs by species and is not fully resolved.

How far it can be extended

Both strategies have been characterised in multiple independently derived resurrection plant lineages.

Caveats

  • Species that dismantle their chlorophyll recover more slowly on rewetting, so the two strategies trade protection against speed.
  • How much of the drying-phase damage is photo-oxidative and how much is purely mechanical has not been separated cleanly.

Still unanswered

  • What determines which strategy a lineage adopts, given that both occur among close relatives in similar habitats.

Last reviewed 2026-09-03

The evidence (2 studies)
  • Some resurrection plants dismantle their chlorophyll as they dry, and rebuild it on rewetting. They are protected but slow to restart — days rather than hours.
  • Others keep their chlorophyll and shield it, often behind pigments that accumulate as the leaf dries and give these plants their characteristic dry colours. They recover much faster and carry more risk while dry.
  • Both strategies occur among close relatives in similar habitats, and what decides between them is not known.
  • Either way, a large part of the drying process is about light rather than about water.

What it costs

Slow growth, and a recovery that is neither instant nor free.

Resurrection plants are small and grow slowly, and it is reasonable to read that as the price of the arrangement — maintaining the capacity to survive drying, and repairing the damage after each cycle, is not compatible with growing fast. Recovery is also less immediate than the photographs suggest. Greening can take hours, but full photosynthetic function commonly takes days, and a plant put through repeated rapid cycles fares worse than one dried slowly and rewetted once. As with every other survival on these pages, the conditions are part of the finding.

The recovery is slower than the photographs suggest. Greening can take hours, but full photosynthetic function commonly takes days — and plants put through repeated rapid cycles fare worse than those dried slowly once.

Well supported

Good evidence backs this, though some details remain open.

Rehydration in desiccation-tolerant angiosperms restores turgor within hours but photosynthetic competence over one to several days, with recovery slower in species that dismantle their photosynthetic apparatus during drying. Repeated rapid dehydration–rehydration cycling reduces performance relative to slow single cycles, and the maintenance and repair costs are consistent with these species’ characteristically slow growth.

Who this applies to
Desiccation-tolerant flowering plants, with the recovery rate differing by strategy.
Studied in
Plantae
Why we rate it this way, and what the caveats are
Well supportedModerate confidence

Recovery kinetics are measured in the studied species. That the slow growth is the price of the tolerance is a reasonable and widely held inference rather than a demonstrated trade-off.

How far it can be extended

The two recovery patterns correspond to the two documented drying strategies, and have been observed across independently derived lineages.

Caveats

  • Species that retain their chlorophyll recover much faster than those that dismantle it, so a single recovery time does not describe the group.
  • Whether slow growth is caused by the tolerance or merely accompanies the habitats where tolerance is needed has not been separated.

Still unanswered

  • How many drying cycles a plant can sustain before damage accumulates measurably, which few studies have followed.

2011Current Opinion in Plant Biology

Programming desiccation-tolerance: from plants to seeds to resurrection plants

Resurrection plants use the same protective repertoire as seeds — sugars, late embryogenesis abundant proteins, antioxidant systems — with the additional problem, unique to green tissue, of shutting down photosynthesis safely so that a drying leaf in sunlight does not destroy itself.

2000Plant Ecology

The evolution of vegetative desiccation tolerance in land plants

Vegetative desiccation tolerance was probably present in the earliest land plants and retained in mosses, but in flowering plants it appears to have been re-evolved independently several times, most likely by redeploying the tolerance programme that seeds already use.

1971Science

Desiccation-tolerant flowering plants in southern Africa

A substantial number of flowering plant species survive the drying of their leaves to air-dryness and recover full function within hours to days of rewetting — a capacity previously thought largely confined to mosses and lichens.
